Abstract

The invention relates to the technical field of food additives, and especially relates to a microcapsule-embedded bread preservative and a preparation method thereof. The microcapsule-embedded bread preservative is composed of the following materials in percentage by weight: 25-80% of wall materials, and 20-75% of preservative core materials; and the preservative core materials are embedded by the wall materials. The wall materials comprise at least one material selected from the following materials: distilled glycerol monostearate, sorbitan monooleate, hydrogenated vegetable oil, monoglyceride laurate, diacetyl tartaric acid esters of mono- and di-glycerides, polyglycerol fatty acid ester, sodium stearyl lactate and calcium stearyl lactate. The preservative core materials comprise the following raw materials in parts by weight: 20.5-65 parts of preservatives, and 10-40 parts of acidity regulators. The synergistic effects of the acidity regulators are made full use of in the microcapsule-embedded bread preservative, so that the freshness keeping effects of the monomer preservatives are thereby improved; moreover, the influence of the preservatives and the acidity regulators on yeast fermentation is reduced by adopting the embedding technology. In addition, emulsifiers are main components of the wall materials, so that the microcapsule-embedded bread preservative also has improvement effects on dough.

Description

technical field [0001] The invention relates to the technical field of food additives, in particular to a microcapsule-embedded bread preservative and a preparation method thereof. Background technique [0002] The main reason why food preservatives can keep food fresh is that it can inhibit the growth of microorganisms in food, thereby protecting food from or being less eroded by bacteria and prolonging its shelf life. However, for fermented foods (such as: bread, steamed buns), it must be fermented by microorganisms (yeasts), so general preservatives effect no significant effect . [0003] At present, most of the bread preservatives in the market are powder mixed compound products, and the preservative monomer can directly contact with the yeast in the dough during use. Although most of the preservatives have obvious antiseptic effects, they will inhibit the fermentation of yeast, thus affecting the proofing time and final fermentation time of the entire dough. finis...
