Description

TEXTURIZED VEGETABLE PROTEIN AND USE THEREOF

FIELD OF THE INVENTION

The invention is broadly in the field of the plant-based savoury market, more precisely in the field of texturized vegetable protein. In particular, the invention concerns a texturized vegetable protein comprising protein from at least two different types of pulses, and its use in food applications.

BACKGROUND OF THE INVENTION

Nowadays, two types of texturized protein exist on the market: texturized or textured vegetable protein (TVP) and high moisture meat analogues (HMMA). Generally, TVP has a water content of less than 10% by weight of the product, while the water content of a HMMA is at least 10% by weight of the product.

It is estimated that the European market supply of TVP will at least double in the next five years from 5000 tons to 11000 tons.

TVP protein has prime importance in food industry as well as from a health point of view. Indeed, TVP is used to replace the meat because the texture provided by the TVP can mimic the texture of the meat. TVP is also cholesterol free and used worldwide due to quality protein of plant source. Its utilization is also related with cultural and economic issues, it is especially popular in vegetarians. Worldwide relief agencies use this product in child school nutrition programmes. It is easy to handle, has a larger shelf-life than real meat and has health benefits.

TVP is generally used to completely replace meat in a food serving or it can be eaten in combination with meat as extenders. TVP resembles meat in terms of texture and taste. Animal protein is expensive and in short supply on worldwide basis. Hence, there is a need to replace animal protein. This can be done by utilizing concentrated or isolated plant proteins. Although most vegetable proteins are of inferior quality to animal protein, legumes are good sources of protein, more specifically pulse proteins.

Today, due to increasing consumer demand for healthy diets, and concerns about rising meat prices and environmental issues, plant protein-based food materials are getting of prime importance as meat alternatives worldwide. This is the reason why various types of plant protein-based meat products are now seen in the market like TVP comprising pea protein, faba bean protein, or lentil protein. However, TVP comprising pea protein, faba bean protein, or lentil protein is not satisfactory to replace meat in all kinds of food applications due to unacceptable sensory evaluation including taste and texture. Therefore, there remains a need in the art for further and/or improved texturized vegetable protein products having different properties than existing TVP products in term of texture, sensory properties, and nutritional value.

SUMMARY OF THE INVENTION

The present inventors have found a texturized vegetable protein (TVP) comprising faba bean protein and pea protein, thereby addressing one or more of the above-mentioned problems in the art.

Accordingly, a first aspect of the invention relates to a texturized vegetable protein comprising faba bean protein and pea protein, wherein the texturized vegetable protein comprises at least 60% by weight of faba bean protein and pea protein based on dry weight of the TVP. Preferably, the texturized vegetable protein comprises faba bean protein concentrate, pea protein concentrate, and pea protein isolate.

As shown in the experimental section, the present inventors realized that the present texturized vegetable protein has unique characteristics including high protein content and provides good results in terms of texture and taste for food applications. Due to the low hydration capacity, the present texturized vegetable protein has high functionality, for instance in vegetarian chorizo that requires chunks to mimic fat inclusion, in vegetarian burgers that require good texture to form the patties, or in plant-based Teewurst that requires meat-like texture. Furthermore, the present texturized vegetable proteins are gluten-free, free from animal-based protein, high in essential amino acids, and suitable for vegetarian and vegan products.

Preferably, the texturized vegetable protein has a hydration capacity of at most 3.0 g water/g of the texturized vegetable protein; preferably a hydration capacity of 1.5 to 3.0 g water/g or 2.0 to 2.8 g water/g of the texturized vegetable protein. Compared to other TVPs on the market, the present texturized vegetable protein has a good fibrous texture and taste, while the hydration rate is lower, thereby leading to advantageous functionalities and satisfactory sensory analysis.

The texturized vegetable protein has satisfactory nutritional and functional properties for food applications. As shown in the example section, good results were obtained when the texturized vegetable protein is used to form meat analogues such as vegetarian chorizo, vegetarian burger, or vegan teewurst.

According to a second aspect, an edible composition is provided, preferably a food or feed product, comprising the texturized vegetable protein as defined herein. A further aspect provides the use of the texturized vegetable protein as defined herein in a food or feed product, preferably in vegetarian products (e.g. vegetarian chorizo or vegetarian burger), vegan products (e.g. a plant-based teewurst), meat products, dairy products, non-dairy products, confectionery products, beverages, food supplements, nutritional products destined to weight control, sports food, medical food, food for elderly, and bakery food products. The texturized vegetable protein can advantageously be used as a meat analogue or meat extender.

The above and further aspects and preferred embodiments of the invention are described in the following sections and in the appended claims. The subject-matter of appended claims is hereby specifically incorporated in this specification.

The term "faba bean protein concentrate" refers to a mixture of protein, starch, and fibers obtained from the faba bean seeds. Methods for obtaining a faba bean protein concentrate are known in the art. Faba bean protein concentrates are typically produced using air classification, which separates beans into fractions based on different particle sizes. Air currents fed into a classifying chamber separate flour based on centrifugal and gravitational forces as a function of size and density, which then generates two main fractions: a fine protein-rich and a coarse starch-rich fraction (Lundgren, 2011, Uppsala, Sweden: SLU, Dept, of Food Science). Electrostatic separation is another dry extraction method relying on differences in dielectric properties of particles instead of their size and density (Sharan et al., 2021, Compr Rev Food Sci Food Saf.;20:401-428).

EXAMPLES

Materials and methods

Determination of protein content by the Dumas method

The apparatus (Leco FP2000) was calibrated with EDTA marketed by Leco under reference 502092. The Quantities of EDTA weighed for the realization of the calibration ranged from 0.08 g to 0.50 g (0.08 g, 0.15 g, 0.25 g, 0.35 g, 0.40 g, 0.50 g). 0.3 g to 1 g of sample was weighed on a precision balance (Sartorius BP61 S, capacity 61 g, sensitivity 0.1 mg) and placed into a ceramic boat. The ceramic boat was automatically placed in an oven at 1200 °C wherein the sample was burnt in a combustion tube by pyrolysis under controlled oxygen flow. Nitrogen compounds are converted to Nj and NOx while other volatile decomposition compounds are retained through adsorbent filters and series of purification regents. All nitrogen compounds are reduced to molecular N, which is quantitatively determined by a thermal conductivity detector. The Nitrogen content was then calculated by a microprocessor.

Results are expressed as a percentage of protein as follows:

% Nitrogen = g of Nitrogen per 100 g of sample

% protein = % Nitrogen x 6.25

Density

The density was measured by pouring the TVP in a 500ml glass and the mass (m) was noted in g. Volume (Vav) was recorded in ml.

Density was calculated as follows: density = m/Vav, wherein m: mass in g

Vav: volume in ml.

Hydration rate

In an 800 ml beaker, 400 ml of water was added with 15 g of TVP. The mixture was left for a hydration time of 15 minutes. The TVP was then collected using a sieve. The TVP was weighted after hydration, noted P. The hydration rate was calculated as: (P - 15) / 15.

Dry matter determination

Total dry matter or solids content was determined gravimetrically as residue remaining after drying. Moisture was evaporated from sample by oven drying.

5 g of sample were weighed in a dry aluminium dish previously weighed (precision balance Ohaus, capacity 410 g, sensitivity 0.001 g). The sample was placed in an oven at 103°C until the residual weight remained constant (at least 24h). Sample was cooled in a desiccator for lh and then immediately weighed. Results are expressed in % (g of dry matter per 100 g of sample).

Dry matter (%) = (m3 - ml)/(m2 - ml) x 100 ml = weight of the dry aluminium dish (in g) m2 = weight of the aluminium dish with the sample before drying (in g) m3 = weight of the aluminium dish with the sample after drying (in g)

Texture

The texture of chorizo and teewurst was defined as the force required to compress over a distance of 20 mm.

The measurement was carried out using a TA-XT2I texture analyser (Stable Micro Systems, Ltd).

Compression cell load, 25 kg

Probe P45C 45° Perspex cone

Table 3: Description of commercially available texturized vegetable protein

Characterization and results

Chemical analysis The solids content and protein content of the TVPs Fl, F2 and F3 illustrating the invention and of the commercially available TVPs was determined as described herein (Table 4).

Table 4: Chemical analysis of TVPs Fl, F2 and F3 illustrating the invention and of commercially available TVPs

The solids content of TVPs Fl, F2 and F3 illustrating the invention and of the commercially available TVPs was higher than 90% by weight of the TVP.

The protein content of TVP Fl, TVP F2 and TVP F3 was at least 65% by weight of the TVP (based on dry matter). This was higher than the protein content of some of the commercially available TVPs, e.g. Vegtein60, Vantastic Foods Soy TVP.

Physical characteristics

The texture including density, size and shape of TVPs Fl, F2 and F3 illustrating the invention and of the commercially available TVPs was determined (Table 5). Table 5: Physical characteristics of TVPs Fl.4, F4.4 and F9.2 illustrating the invention and of commercially available TVPs

Photographs illustrating the shape of the TVPs Fl (Figure 1A), F2 (Figure IB) and F3 (Figure 1C) according to embodiments of the invention and of a commercially available texturized pea protein Vegtein60 (Figure ID) are provided in Figure 1.

Functional properties

The hydration capacity of the TVPs Fl, F2 and F3 illustrating the invention and of the commercially available TVPs was determined (Table 6). Table 6: Hydration capacity of TVP Fl, TVP F2 and TVP F3 illustrating the invention and of commercially available TVPs.

Hydration capacity of the commercially available TVPs ranged from 3.4 to 4.9 g water / g TVP. TVP Fl, TVP F2 and TVP F3 had a hydration capacity of at most 3.0 g water /g TVP, and hence lower than the hydration capacity of the commercially available TVPs.

Sensory analysis

A sensory analysis was performed for TVPs Fl, F2 and F3 according to embodiments of the invention and for the commercially available texturized pea protein Vegtein60. The sensory analysis was performed as described above under cold conditions and hot conditions. The results are provided in Table 7.

Table 7: Results of sensory analysis after 10 min for TVPs Fl, F2 and F3 illustrating the invention and for a commercially available TVP.

The texturized vegetable proteins illustrating the invention provided good results in term of sensory analysis both in cold and hot conditions with different taste and texture for the different TVPs. It is noted that faba bean brings crispiness and vegetal taste. The TVPs Fl, F2 and F3 according to embodiments of the invention had a hydration capacity of 2.2, 2.0, and 2.8 g of water per g of TVPs respectively. Overall, these TVPs gave good results in terms of texture and taste.

Conclusion

All the TVP products have different protein content, particle size and density and particle size and shape. Moreover, TVP Fl, TVP F2 and TVP F3 illustrating the invention have a lower hydration capacity than the commercially available TVPs, and hence the TVPs according to embodiments of the invention will have different behaviour in applications depending on the conditions of use.

The lower hydration capacity of at most 3.0 g water/ g TVP provides texturized vegetable proteins with good sensory properties (both cold and hot conditions) and excellent properties for use in particular food products such as vegetarian chorizo, vegetarian burger, and vegan teewurst (as shown in Examples 3-5).

Example 3: Use of a texturized vegetable protein according to embodiments of the invention and of comparative texturized pea proteins in vegetarian chorizo

In this example, texturized vegetable proteins according to embodiments of the invention were used in a vegetarian chorizo and advantageously allow to obtain a vegetarian chorizo with improved texture and visual aspect, namely imitation of fat pieces in delicatessen (Figure 2).

The composition of the vegetarian chorizo is as provided in Table 8. The ingredients list contains: sunflower oil, egg albumen, pea protein (PISANE™ M9), natural flavour, pea starch (NASTAR™ Instant), potato starch, pea cell-wall fibre (SWELITE™ C), colouring, spices, ascorbic acid, xanthan, locust bean gum, and texturized vegetable protein.

The tested TVPs were TVP Fl or F2 according to embodiments of the invention (as described in Examples 1 and 2, referred to as "TVP Fl" and "TVP F2"), Texta Pois 65/70 (SotexPro, referred to as "SotexPro"), non-GMO texturized pea protein (Zumbro Pure Farms, referred to as "Zumbro TVP"), and Ancient Balance D-Texturized Pea Protein Cl (R&S Blumos, referred to as "Blumos Cl"). Nutrition information of a vegetarian chorizo according to an embodiment is as follows (per serving of 30 g): Energy (Kcal): 93, Fat (g): 7.9, of which saturated fat: 0.9, Total sugars (g): 2.3, Protein (g): 3.7, Fibre (g): 0.3.

Table 8: Composition of vegetarian chorizos illustrating the invention and comparative chorizos

The vegetarian chorizos were prepared according to the following steps: hydrate the TVP with the adapted quantity of water and time; in Stephan mixer, pour the remaining water and add egg, xanthan gum, locust bean gum and PISANE™ M9. Mix for 1 minute at 1500 rpm; - add the rest of the powders (except spices and colouring agents) and mix again for 1 minute at 1500 rpm; add oil (under vacuum) and mix for 1 minute at 3000 rpm; add the spices and the colouring agents, mix for 1 minute at 3000 rpm; add the hydrated TVP and mix for 30 seconds at 1500 rpm; fill in casings (55 mm diameter, 50 cm length) (casings are hydrated in advance in water at 30°C for 20 min; cook in oven at 75°C (till 72°C) (~2.5 hours) in steam atmosphere; cool down and pack in appropriate packaging.

Results

No difference was observed with the different TVPs during the process.

Dry matter, pH, texture (TAXT2/pic) and sensory analysis were made. The results are provided in Table 9. The texture was measured using a T / TAXT2 (using a slice of 2 cm of height).

Table 9: Analysis of vegetarian chorizos illustrating the invention and of comparative chorizos

*Properties considered as undesirable are indicated in italics

It can be seen from Table 9 that the pH and dry matter were not affected by the different TVPs.

The chorizo with Zumbro TVP had the lowest hardness. This was observed during the sensory analysis.

The texturized vegetable proteins TVP Fl and TVP F2 illustrating the invention gave the best results in terms of visual aspect because the big pieces better mimic fat inclusion (Figure 2A). Less visual pieces were observed in the vegetarian chorizos comprising SotexPro (Figure 2B), Zumbro TVP (Figure 2C) and Blumos Cl (Figure 2D). The sensory analysis of the chorizos with TVP Fl and TVP F2 was also satisfactory with less dry taste in comparison with the vegetarian chorizos comprising Zumbro TVP or Blumos Cl. A nice texture and taste were observed in the vegetarian chorizo comprising SotexPro but no pieces mimicking the fat inclusion were observed (Figure 2B). In conclusion, the faba bean/pea-based TVPs gave good results in vegetarian chorizo in term of visual aspect, texture and taste. The big pieces observed with the texturized vegetable proteins illustrating the invention are recommended for this application for a better visual aspect that mimic fat inclusion in delicatessen.

Example 4: Use of texturized vegetable protein according to embodiments of the invention and of comparative texturized pea proteins in a vegetarian burger

In this example, texturized vegetable proteins according to embodiments of the invention are used in a vegetarian burger and advantageously allow to obtain a vegetarian burger with improved texture (Table 11).

The composition of the vegetarian burger is as provided in Table 10. The ingredients list contains: water, vegetables (carrots and tomatoes), sunflower oil, egg albumen, pea cell-wall fibre (SWELITE™ C), methylcellulose, spices, and texturized vegetable protein.

The tested TVPs were TVP Fl or F2 according to embodiments of the invention (as described in Examples 1 and 2, referred to as "TVP Fl" and "TVP F2"), Texta Pois 65/70 (SotexPro, referred to as "SotexPro"), non-GMO texturized pea protein (Zumbro Pure Farms, referred to as "Zumbro TVP"), and Ancient Balance D-Texturized Pea Protein Cl (R&S Blumos, referred to as "Blumos Cl").

Nutrition information of a vegetarian burger according to an embodiment is as follows (per serving of 100 g): Energy (Kcal): 114, Fat (g): 5.6, of which saturated fat: 0.7, Total sugars (g): 3.8, Protein (g): 10.9, Fibre (g): 2.3.

Table 10: Composition of vegetarian burgers illustrating the invention and comparative burgers, and of hydration ratio and time of the TVPs illustrating the invention and comparative TVPs

Hydration ratio and time were different according to the different TVPs. Therefore, the quantity of TVP and water was determined for each TVP. Also, as the water content of the recipe is not high, the TVP was hydrated with water separate from the water of the recipe. In this way, a better processing was achieved.

The vegetarian burgers were prepared according to the following steps: hydrate the TVP with the adapted quantity of water and time; cook the vegetables in hot water (95°C) for 3 minutes; in the Stephan mixer with knife, disperse powder in water, mix 30 seconds 750 rpm (25%); - add oil, mix 15 seconds 1500 rpm (50%); add vegetables, mix 30 seconds 3000 rpm (100%); add hydrated TVP, mix 30 seconds 3000 rpm (100%); form the patties (100g) and store at -18°C.

Cook in pan frying for 12 minutes. Different process observations and results of sensory analysis are provided in Table 11.

Table 11: Process observations and sensory analysis of vegetarian burgers illustrating the invention and of comparative burgers

*Properties considered as undesirable are indicated in italics

It was very difficult to form a vegetarian burger comprising SotexPro, Zumbro TVP or Blumos Cl. The paste was too soft and liquid leading to an inhomogeneous formation of patties. No issues were observed for forming the patties comprising TVP Fl and TVP F2. Indeed, the results of the texture confirm that TVP Fl and TVP F2 illustrating the invention provided a better texture for forming the patties than the comparative TVPs (SotexPro, Zumbro TVP and Blumos Cl).

In addition to the better and firmer texture, the taste of the vegetarian burgers comprising TVP Fl illustrating the invention was satisfactory. For the vegetarian burgers comprising TVP F2, flavours can be added to overcome the bitter taste.

Example 5: Use of texturized vegetable proteins according to embodiments of the invention and of comparative texturized pea proteins in a plant-based Teewurst

In this example, the texturized vegetable proteins according to embodiments of the invention are used in a plant-based Teewurst and advantageously allow to obtain a plant-based Teewurst with meat-like texture (Table 13).

The composition of the plant-based Teewurst is as provided in Table 12. The ingredients list contains: water, vegetables (carrots, potato, green pepper, onion), sunflower oil, pea protein (PISANE™ M9), pea starch (NASTAR™ Instant), potato starch, defatted vegetable broth, spices, beetroot juice powder, carrageenan, bacon flavour, ascorbic acid, and texturized vegetable protein. The tested TVPs were TVP Fl or TVP F2 according to embodiments of the invention (as described in Examples 1 and 2, referred to as "TVP Fl" and "TVP F2" respectively), Texta Pois 65/70 (SotexPro, referred to as "SotexPro"), non-GMO texturized pea protein (Zumbro Pure Farms, referred to as "Zumbro TVP"), and Ancient Balance D-Texturized Pea Protein Cl (R&S Blumos, referred to as "Blumos Cl").

Table 12: Composition of plant-based Teewurst illustrating the invention and comparative Teewurst The plant-based Teewurst were prepared according to the following steps: blanch all vegetables in hot water (85°C for 20 minutes); hydrate TVP with the adapted quantity of water and for an adapted time; in Stephan mixer, put the vegetables for 1 minutes at 3000 rpm (100%); add the powder, mix 1 minutes at 1500 rpm (50%); - add oil, mix 1 minutes at 3000 rpm (100%); add hydrated TVP, mix 30 seconds at 1500 rpm (50%). The paste was filled in glass jars and pasteurised (85°C core temperature) (1 hours in oven at 95°C).

In this application, texturized vegetable proteins were used for the meat-like texture that a Teewurst needs. No difference was observed with the different TVPs during the process. The TVP Fl and TVP F2 illustrating the invention provided the meat-like texture that a Teewurst needs.

Dry matter, pH, texture (TAXT2/cone) and sensory analysis were made. The results are provided in Table 13. The texture was measured using a T / TAXT2, with a Cone Perspex 45C (using a slice of 2 cm of height).

Table 13: Analysis of plant-based Teewurst illustrating the invention and of comparative Teewurst

The pH was not affected by the different TVPs, except for the Teewurst comprising SotexPro which had slightly lower pH. Teewurst comprising TVP Fl and TVP F2 illustrating the invention had slightly higher dry matter. This can be explained by the lower hydration capacity.

Except for the texture of the Teewurst comprising Zumbro TVP (lower hardness), all the trials had quite the same hardness. The Teewurst comprising SotexPro had the better spread-ability.

Taste was not an issue in this application, all the trials were vegetal and no off-note was detected. The TVP Fl and TVP F2 illustrating the invention thus demonstrated satisfactory taste when used for preparing a plant-based Teewurst.

For this application, it is possible to grind the chunks of TVP Fl and TVP F2 illustrating the invention before incorporation in the matrix, in order to make the pate homogeneous and more less spreadable. The texturized vegetable proteins illustrating the invention provided in the form of chunks thus offer a flexible solution to customers for preparing plant-based and vegetarian food products. Conclusion

In chorizo, where higher particles size is preferred, the present texturized vegetable proteins provided for a good texture and better visual aspect with bigger pieces that mimics delicatessen. In burgers, the present texturized vegetable proteins resulted in a firmer texture with excellent properties for forming the patties. In Teewurst, where lower particles size are better for the spreadability of the pate, the present texturized vegetable proteins resulted in good taste and meat-like texture.

Thus, the texturized vegetable proteins comprising pea protein and faba bean protein according to the invention give good results in terms of texture and taste for food applications. Due to the low hydration capacity, the present texturized vegetable proteins have high functionality for instance in vegetarian chorizo that require chunks to mimic fat inclusion, in vegetarian burgers that require good texture to form the patties, or in plant-based Teewurst that require meat-like texture. Furthermore, the present texturized vegetable proteins are high in protein, free of animal-based protein, free of gluten, high in essential amino acids, and suitable for vegetarian and vegan products.
