Thermo-sensitive sodium bicarbonate microcapsule and preparation method thereof

Abstract

The invention discloses a thermo-sensitive sodium bicarbonate microcapsule. The thermo-sensitive sodium bicarbonate microcapsule comprises a main ingredient, a core material and an auxiliary material, wherein the main ingredient takes the mixture of glyceryl monostearate and lard as a wall material; the core material adopts sodium bicarbonate; the auxiliary material adopts beta-cyclodextrin. The thermo-sensitive sodium bicarbonate microcapsule has the advantages that the temperature sensitivity of the microcapsule is improved due to the addition of lard; the encapsulating effect and the granulation property of the microcapsule can be improved effectively due to the addition of beta-cyclodextrin; the microcapsule is high in granulation property, is free of external world impact, stable in physical and chemical properties at low temperature, and sensitive to high temperature; when the temperature reaches 60 DEG C, the wall material melts, the core material is released and can release carbon dioxide more effectively via thermal decomposition or a neutralization / double decomposition reaction between the core material and an acid substance, so that the bulking effect can be better. The preparation method has the advantages that the preparation technology is simple; the preparation conditions are easy to control; the prepared product is safe and nontoxic.

Description

technical field [0001] The invention belongs to the field of food processing and food ingredients, in particular to a temperature-sensitive sodium bicarbonate microcapsule and a preparation method thereof. Background technique [0002] Microcapsules refer to small particles with a core-shell structure that wrap gaseous, liquid or solid substances inside, with particle sizes ranging from millimeters to nanometers. The outer material of the microcapsule is the wall material, also known as the membrane material, which is generally a natural or synthetic polymer material; the inner material is the core material, also known as the content or inclusion. Microcapsule technology is a technology that embeds the core material in a tiny closed capsule formed by the wall material. Microencapsulating the reactive, sensitive or volatile core material can effectively separate the core material from the surrounding environment, reduce or avoid the adverse effects of the external environmen...

Problems solved by technology

But CO is sometimes released by thermal decomposition 2 The speed is too slow to achieve the ideal bulking effect, and the acidic substance is added in advance, and the neutralization reaction or metathesis reaction will occur prematurely to release CO 2 , the same can not achieve the purpose of leavening; in addition, some prefabricated special dough often contains acidic ingredients, such as diced fruit, sour cream, etc., they will react when they come into contact with sodium bicarbonate, and consume sodium bicarbonate , so that the dough reduces or even loses its expansion ability during the baking process, and the resulting baked products have a hard taste and poor quality
