Description
Technical field
The invention belongs to food processing field, and in particular to a kind of red bean jelly and preparation method thereof, red bean of the invention
Jelly includes whole grain red bean, and outward appearance, mouthfeel are good.
Background technology
Jelly is a kind of high, soft, the flexible food of moisture, from west.Jelly is because its outward appearance is sparkling and crystal-clear, color
The soft cunning of gorgeous, mouthfeel, fresh and sweet moisten and deep liked by people, especially children.With the improvement of living standards, people are to stopping
The requirement of not busy food also more and more higher, not exclusively requires tasty, safety and sanitation, and should have certain health care work(
Energy.
Red bean (in the present invention, being otherwise referred to as " red bean ", " red bean " etc. below) is legume rde bean or red
The seed of beans, red bean has the effects such as promoting lactation, clearing heat and detoxicating, defaecation diuresis, dispelling malignant blood, full dissipate-swelling to make inside traditional Chinese medical science medicinal material
With.Red bean can whole grain eat, be generally used for cooking, cook congee, do red bean soup or ice lolly, ice cream etc.There is " red bean for dish
Rib soup " etc..It is in silty sand after steaming because Red Bean Starch content is higher, and has the fragrance of uniqueness, therefore is commonly used to make beans
Sand, for the fillings of various pudding's millet cake.
Enterprise is had at present and is conceived to the jellies product that exploitation with the addition of red bean, to meet consumer to jelly production mouthful
Pursuit in terms of sense, taste and health-nutrition.Zhang Jieming patent application CN 102228170A disclose a kind of five cereals
Jelly and preparation method thereof, however, its product be mainly by the five cereals such as red bean be milled into slurries add to jelly its
In its raw material, the jelly made employs the natural color of five cereals in itself.For another example " red bean corn is really for Zhao Yu academic dissertation
Freeze the research of production technology " jelly being made using red bean and corn as raw material is disclosed, it into jelly raw material mainly by adding
Plus proper amount of red bean juice and corn juice complete production, products obtained therefrom is opaque.Patent of invention CN 104207032A are disclosed
A kind of red bean pudding and preparation method, however, milk powder, emulsifying agent, grease are with the addition of in jelly hyaline layer, after clipped emulsification
Jelly layer is no longer transparent, loses the glittering and translucent characteristic of jelly production, and full grains can not be seen through jelly cup naked eyes
Whole grain sugaring red bean, it is impossible to bring visual impact for consumer.
Do not occur the transparent jelly production for including whole grain sugaring red bean also in the market, include the jelly of whole grain red bean
Production there are following technological difficulties：
First, jelly solid content is usually Brix=15-25wt%, enterprise is typically difficult to produce Brix>25wt%
Jelly production, solid content is too high in jelly, then obvious increase cost, while solid content is higher, it is meant that use
More sweeteners (such as white granulated sugar, glucose syrup), its jelly sugariness increase, influence eating mouth feel, trigger consumer to strong
The worry of health.Research finds that the sugaring solid content of red bean cannot be below 50wt%, when less than 50wt%, sugaring red bean mouthful
Induct hard, lose viscous glutinous mouthfeel.Sugaring red bean is added in jelly, then requires that the solid content of jelly can not be too low, otherwise can send out
Sugar in raw sugaring red bean is migrated into jelly hyaline layer, and similarly the moisture in jelly layer can be migrated into sugaring red bean, most
Dynamic equilibrium is reached eventually, causes sugaring red bean solid content to be inducted firmly less than 50wt% deutostomas, mouthfeel when substantially reducing edible.
Second, jelly is processed into the acidulated acid food (pH of fruit taste mostly<4.6), using pasteurize (85
DEG C, 15-20min) technique.And sugaring red bean is not suitable for being fabricated to tart flavour, mainly the sugaring red bean taste of tart flavour, mouthfeel compared with
Difference, can be mistakenly considered the tapinoma-odour produced after red bean is rotten after eating.Accordingly, it would be desirable to which red bean jelly is processed into neutral food
(pH=5.0-6.5), to ensure edible safety, high pressure sterilization technique (121 DEG C, 20min) need to be taken.
Third, conventional sugaring red bean is easily broken in jelly production process, crushed in high pressure sterilization, cooling procedure
Red bean skin or fiber fines can be migrated into jelly hyaline layer, it appears that such as impurity, are influenceed product appearance, are mistakenly considered different
Thing；Also, the pigment that red bean epidermis is carried itself has unstability, easily darken dimmed, and then influence fruit
Freeze the exterior quality of product.
Fourth, common malt syrup or glucose syrup are used in formula, and after high pressure sterilization and in storage process, product meeting
Generation brown stain influences product appearance into dark yellow.
The content of the invention
To solve the above problems, the present inventor carries out in depth studying comprehensively to the materials of jelly, proportioning and manufacture craft,
Obtain the jelly production for including whole grain red bean of the present invention.The red bean jelly of the present invention is glittering and translucent, sugaring red bean and fruit
Freeze the clearly demarcated not batch mixing of transparent layer time, no red bean skin or fiber transfer are into jelly hyaline layer.Sugaring red bean particle is complete, without bright

Embodiment
Term " conformal serviceability rate " used in the present invention refers to that the complete red bean weight of grain type accounts for red bean after cooking
The ratio of gross weight.
Below with reference to accompanying drawings, the embodiment to the present invention is described in detail.
In one aspect, present invention firstly provides the preparation method of sugaring red bean, it is red bean that it, which is formulated consumption,
30wt%-45wt%, beans softening agent 0.3wt%-1wt%, calgon 0.3wt%-1wt%, high maltose syrup
25wt%-40wt%, white granulated sugar 5wt%-20wt% and surplus pure water；A kind of embodiment of its fabrication processing is such as
Shown in Fig. 1, this method is mainly included the following steps that：
Raw material is selected：It is preferred that kind is when the deer beans produced per year, it is crushed with big, fuller than other kinds grain after boiling
The low advantage of rate.Classifying screen selects a diameter of 6-7mm use, it is desirable to which particle is complete, color and luster is consistent, and artificial removal damages by worms, mould
Become grain.
Red bean soaks：The red bean that classifying screen is selected is poured into stainless steel sink, plus the water of 2-5 times of weight soaks,
Soak time about 10-30h, preferably 20h (summer)；15-35h, preferably 25h (spring and autumn)；20-35h, preferably 30h (winter), leaching
The screened strong beans of rejecting of red bean after bubble processing.Process conditions that the temperature of immersion, time cook to follow-up red bean and
Effect has considerable influence, and soaking temperature is too low, soak time is not enough can cause beans expansion insufficient, causes follow-up cook to be stranded
Difficulty, brew time is long, and red bean epidermis percentage of damage is high, influences sugaring effect；Soaking temperature is too high, long soaking time is easily boiled
Make ripe rotten frangible, grain type is poor or does not have grain type, it is therefore desirable to the suitable immersion water temperature of control and soak time.It is suitable in order to determine
Soaking conditionses, inventor enters to different immersion water temperatures and corresponding influence of the soak time to the conformal serviceability rate of red bean
Experiment is gone, as a result as shown in table 1 and Fig. 2：
The soaking temperature of table 1, influence of the time to the conformal integrity of red bean
| Water temperature DEG C | 10h | 15h | 20h | 25h | 30h | 35h |
| 35℃ | 92% | 95% | 99% | 94% | 92% | 89% |
| 25℃ | 90% | 95% | 98% | 96% | 94% | 92% |
| 15℃ | 85% | 90% | 93% | 99% | 97% | 95% |
| 5℃ | 82% | 85% | 90% | 93% | 99% | 94% |
As a result：Can be seen that from above test data, soaking conditionses are 5 DEG C, 30h when, the conformal serviceability rate of red bean is up to 99%；
Soaking conditionses are 15 DEG C, 25h when, the conformal serviceability rate of red bean is up to 99%；Soaking conditionses be 25 DEG C, 20h when, red bean is conformal complete
Availability ratio is up to 98%；Soaking conditionses are 35 DEG C, 20h when the conformal serviceability rate of red bean up to 99%.It therefore, it can be become according to weather conditions
Change to adjust soak time, soaking temperature and soak time can also be fixed to operate.
Drain：Red bean after immersion is filtered out soaking water with sieve；
Swing and wash：Still there is loose colour (pinkiness) on red bean surface after immersion, it is necessary to be rinsed again once with water, red to remove
The loose colour on red bean surface；
Cook：Cooked beans uses the pure water that 2-5 times of weight of red bean is put into normal pressure cooking technology, steam-jacked kettle, plus
Enter beans softening agent and calgon, opening to stir and lead to steam and heat is completely dissolved beans softening agent, opens big cap relief valve
Door, steam pressure is controlled in 2-3kg/cm2, boil after about 20-25min (winter about 20min, summer about 25min), steam pressure
Turn down to 0.3-0.6kg/cm2, 3-8min closes natural immersion 25-40min after steam under slight boiling condition, is drained the water with screen cloth.
The present inventor is found through experiments that shadow can be produced to the conformality and degree of raw and cooked of red bean by closing the time of natural immersion after steam
Ring, as a result as shown in table 2：
Table 2 closes influence of the steam natural immersion time to the conformality and degree of raw and cooked of red bean
Degree of raw and cooked is evaluated：The finger afterturn of beans after cooking, feel powdery, without lump preferably, and should be broken without skin of beancurd
Split situation；Without hard core during chewing.
Test by contrast, soak time 30min is drawn from table 2, preferably, conformal serviceability rate is up to 98% for the degree of raw and cooked of its beans.
Because by immersion in advance before red bean boiling, the abundant water swelling of beans is effectively reduced starch gelatinization in red bean
Time, gelatinization effect is improved, beneficial to cooking, while improving the conformal serviceability rate of bean or pea.The present inventor was once tested, and red bean is cooked
If preceding without immersion treatment, cooked directly in steam-jacked kettle, natural immersion is for up to after 50min after closing steam
Could be ripe soft, conformal serviceability rate is 95%, and the skin of beancurd rupture during cooked beans of non-premenstruum (premenstrua) immersion treatment is serious, while in the presence of
The strong beans that part is not removed are stiff, and now non-strong beans are ripe soft, cause the inconsistent situation of degree of raw and cooked, to follow-up sugaring
Bring difficulty.Therefore, before cooking, early stage immersion treatment is preferably carried out.
To prevent in product storage process because the unstable color occurred of pigment that red bean epidermis is carried itself becomes
It is deep dimmed, 0.5% calgon is added when being cooked before red bean sugaring, can effectively stablize the coat color of red bean,
Protect product color.
Sugaring：High maltose syrup Brix=35-40% after 85 DEG C of hot water dilutions, drains the water after step 5 boiling
Red bean in pour into its 2 times of weight Brix=35-40% high malt sugar slurries, the sugared temperature 50 C of leaching, filter after leaching sugar 10-15h
Fall syrup.
Secondary sugaring：Once soak and white granulated sugar is added in the syrup being filtrated to get after sugar, Brix=45- after dissolving is boiled in heating
55%, added when being cooled to 75-85 DEG C and once soak the red bean after sugar, syrup is filtered after leaching sugar 8-12h.
Three sugarings：White granulated sugar is added again in the syrup being filtrated to get after secondary leaching sugar, and Brix after dissolving is boiled in heating
Syrup is filtered after=65-75%, the red bean added when being cooled to 75-85 DEG C after secondary leaching sugar, leaching sugar 10-15h.
Had shown that through research, if sugaring red bean has following problem using a sugaring technique：
1st, the sugaring red bean that a sugaring technique makes is due to syrup concentration height, and osmotic pressure is big, and red bean top layer is preferably permeated
Enter syrup, but red bean inner core is difficult immersion syrup, causes the sugaring red bean mouthfeel made to be hardened, and lacks and glues glutinous mouthfeel, surface
Intensely dark pool；
2nd, its conformal intact degree of the sugaring red bean that a sugaring technique makes is low compared with three sugaring red beans, and red bean epidermis is broken
Split, starch has dissolution in beans, be added in jelly again that red bean epidermis has and come off after high pressure sterilization.Starch dissolution is permeated in beans
Enter jelly hyaline layer, influence product appearance；
3rd, sweetened bean paste spilling is mixed into carbohydrate gum liquid during a sugaring, product appearance is deteriorated, is caused fraction defective to improve.This be by
Syrup concentration is too high when using a sugaring, then osmotic pressure is big, and the liquid glucose of high concentration easily blocks red bean infiltration lane, red bean
In moisture be not easy same syrup and enter line replacement, liquid glucose is difficult to penetrate into red bean centre, causes red bean center to reach requirement
The time of pol is longer, influences production efficiency.
The present invention in each sugaring process, gradually steps up the concentration of liquid glucose using three sugaring techniques, it can be ensured that production
Product particle shape is complete, bright in color, mouthfeel soft durometer are moderate, pol is uniform.As preferred embodiment, first time sugar concentration
40%, sugaring time 12h；Second of sugar concentration is 50%, sugaring time 10h；Third time sugar concentration 70%, sugaring time
12h, can reach the sugared effect of preferably leaching.Pass through three sugaring techniques, it is ensured that product particle shape is complete, bright in color, mouthfeel are soft
The good characteristics such as hardness is moderate, pol is uniform.The liquid glucose reusable edible being filtrated to get, reduces cost of material.
3 three sugaring parameters of table and interpretation of result
It can be seen from the experimental result described in upper table, when a 40% sugaring syrup concentration (experiment 1vs comparative tests

1vs comparative test 5-6) when, sugaring red bean of the invention has optimal color and luster, mouthfeel and profile (integrity degree), from above-mentioned knot
Fruit understands, influences maximum factor to be three syrup concentrations sugaring red bean profile, mouthfeel.Maximum factor is influenceed on color and luster is
Secondary syrup concentration.
On the other hand, the present invention carries out sugaring instead of part white granulated sugar using high maltose syrup to red bean, and it has
Following advantage：
1st, part white granulated sugar is replaced with high maltose syrup has that sugariness is low, sugariness is gentle, mouthfeel is viscous to make sugaring red bean
The advantage of glutinous good toughness；Compared with white granulated sugar, the sugariness of high maltose syrup is 40% of white granulated sugar or so,
2nd, what is more important high maltose syrup can play a part of preventing age of starch in sugaring red bean, and moisture retention is good,
Its surface of long-time storage will not be dried, the characteristics of mouthfeel will not be hardened.
Syrup, which swings, to be washed：Red bean after soaking sugar through third time, because surface is stained with the syrup of high concentration, it is difficult to which drip is except clean
Cause surfaces of tacky.Solid content Brix=50%, 70 DEG C of high malt sugar slurries are prepared, by the red bean after sugaring in the syrup
In swing and wash a viscous liquid glucose to remove surface, drain again.
Drying：It is placed in 60-65 DEG C of drying room, dries 30min and do not glued not firmly to surface, is cooled to standby after 25-35 DEG C.
