in some embodiments, the modified starch comprises at least one of hydroxypropyl distarch phosphate, acetylated distarch phosphate, sodium starch octenyl succinate.
Preferably, the modified starch comprises a combination of hydroxypropyl distarch phosphate, acetylated distarch phosphate and sodium starch octenyl succinate in a weight ratio of 1: (1-1.4): (0.3-0.7).
More preferably, the modified starch comprises a combination of hydroxypropyl distarch phosphate, acetylated distarch phosphate and sodium starch octenyl succinate in a weight ratio of 1:1.2:0.5.
in some embodiments, the thickener further comprises a low methoxy pectin in a weight ratio of 1: (1-2).
Preferably, the weight ratio of the low methoxy pectin to the modified starch is 1:1.5.
in some embodiments, the feedstock further comprises 10% -15% by weight apple juice.
Preferably, the raw material further comprises 12% by weight of apple juice.
More preferably, the apple juice is concentrated apple juice, and the solid content reaches 65-70%.
The source of apple juice in the present invention is not particularly limited and may be commercially available or may be prepared by any of the methods well known to those skilled in the art, including but not limited to the preparation steps including: cleaning, crushing, squeezing juice, filtering, sterilizing and concentrating.
In some embodiments, the feedstock further comprises 0.1 to 0.5 weight percent of an auxiliary agent.
Preferably, the raw materials comprise 0.3% by weight of auxiliaries.
In some embodiments, the adjunct comprises at least one of calcium lactate, calcium citrate, calcium chloride.
Preferably, the auxiliary agent is calcium lactate.
In some embodiments, the colorant is gardenia blue pigment.
In some embodiments, the acidity regulator is citric acid.
The applicant prepares a kind of blueberry jam in advance, make the shelf life of this blueberry jam longer, stability is good, and mouthfeel is abundant through the proportion of the composition, but the applicant feels that this blueberry jam has relatively high sugar degree and poor spreadability after a period of time, the applicant has improved on the original basis, nevertheless find the sugar degree reduces and can make the stability worsen in the course of improvement, the phenomenon of dehydration and sponginess appears easily in the course of storage, the applicant finds after a large number of researches that adopts the specific thickening agent to mix with certain proportion of auxiliary agent in this system again, especially the thickening agent includes modified starch, xanthan gum, low methoxy pectin, and the auxiliary agent is calcium lactate, can make the jam prepared have excellent stability and better spreadability while reducing sugar degree, the applicant considers that the possible reasons are that modified starch hydroxypropyl di-starch phosphate, acetylated di-starch phosphate form stable aggregation group through intertwining with dietary fiber in the concentrated apple juice, while sodium octenyl succinic acid starch is added to reduce the surface tension in the system, this system stability is promoted; on the other hand, certain low methoxy pectin is added to generate bridging effect with calcium lactate to form gel, so that the stability of the blueberry jam is further promoted, the spreadability of the blueberry jam is improved, and in addition, the organization feel of the gel is improved and the water separation phenomenon is reduced by adding the xanthan gum with a specific proportion into a system.
The invention also provides a preparation method of the easy-to-smear blueberry jam, which at least comprises the following steps:
(1) Uniformly mixing white granulated sugar and a thickener, adding the mixture into hot water, and uniformly stirring to obtain a mixture A;
(2) Adding blueberry pulp, apple juice, an auxiliary agent and a colorant into the mixture A, heating and stirring until the mixture A is uniformly mixed to obtain a mixture B;
(3) Adding an acidity regulator into the mixture B to regulate the pH value, stirring and mixing uniformly under the condition of heat preservation, heating to more than 95 ℃, stirring uniformly to obtain a soluble solid, and then carrying out hot canning and water boiling to obtain a blueberry jam finished product.
In some embodiments, the hot water in step (1) has a temperature of 90-95 ℃.
Preferably, the temperature of the hot water in the step (1) is 93 ℃.
In some embodiments, the temperature of heating in step (2) is 88-92 ℃.
Preferably, the temperature of heating in step (2) is 90 ℃.
In some embodiments, the pH in step (3) ranges from 3.7 to 3.9.
The beneficial effects are that: according to the invention, a specific thickener and a certain proportion of auxiliary agents are adopted, particularly, the thickener comprises modified starch, xanthan gum and low methoxy pectin, and when the auxiliary agent is calcium lactate, the prepared blueberry jam has excellent stability and better spreadability while the sugar degree is reduced; and the organization sense of the gel is improved, and the water separation phenomenon is reduced.
