Preparation process of freezing-resistant crystal balls

Abstract

The invention provides a preparation process of freezing-resistant crystal balls. The preparation process comprises the steps of step-by-step gelling, heating, forming, sugaring concentration and the like; (1) sodium alginate, agar, carrageenan, konjac gum and locust bean gum powder as raw materials; (2) a physical means of adding coconut oil and a water-soluble emulsifier to refine water distribution is used; (3) a high and new technology for compounding gel with rigid gel and elastic gel by high-temperature instant forming and low-temperature slow forming is used; and (4) the solid content is increased by sugaring. The technical problem that ice crystals are formed due to gel freezing volume expansion in the freezing process of crystal balls to cause that a gel structure is prone to damage in the prior art is solved. The preparation process disclosed by the invention is reasonable in design, and the prepared freezing-resistant crystal balls have the advantages that the ice crystals are not prone to form after freezing, the gel structure is not prone to damage, and the mouthfeel is good.

Description

technical field

[0001] The invention belongs to the technical field of food processing, in particular to a preparation process of edible crystal balls, in particular to a preparation process of freeze-resistant crystal balls. Background technique

[0002] Hantian crystal balls are often used as raw materials for the preparation of milk tea. It is a gel product with a water content of more than 80%. During the freezing process of the crystal balls, the water is easy to form ice crystals, which will enlarge the gel structure and cause the gel structure to be destroyed.

[0003] At present, the research on freeze-resistant technology mainly focuses on liquid products or semi-solid substances. According to literature records, liquid milk products can improve the freeze-thaw stability of products by adding stabilizers; Ice crystals, while the research on the freeze resistance of gel crystal balls is less, because of the special gel structure of crystal balls, the water content is...
