Problems solved by technology

The applicant found in the research that after the green tofu is stored in vacuum packaging, due to chemical and biological changes such as Maillard reaction and microbial fermentation, the color of the green tofu will continue to deepen with time, which will affect its visual effect, and the surface of the green tofu will change. Some yellow-brown spots appear, affecting its visual sensory effect

Abstract

The invention relates to a green tofu with stable color, which belongs to the technical field of food processing. The green tofu is prepared from the following ingredients: 0.25-0.6% of polydimethylsiloxane and 0.2-0.4% of sodium carboxymethyl cellulose , 0.5-0.8% epigallocatechin, 0.05-0.2% propylene glycol, 0.1-0.3% konjac gum, 0.6-1.0% gluconolactone, and the balance is soybean milk, wherein the content of soybeans in the soybean milk is 5-10% % (g / mL), the edamame curd prepared by the present invention has the same taste and quality after vacuum packaging, and can keep its color unchanged within 60 days.

Description

technical field [0001] The invention relates to a brand-new edamame product, in particular to a color-stable edamame. Background technique [0002] Hairy tofu is a famous traditional dish in Huizhou (now Huangshan City, Anhui Province). It is artificially fermented to make a layer of white hairs grow on the surface of the tofu. Because tofu converts the vegetable protein into a variety of amino acids after fermentation, it tastes very fresh after cooking. [0003] The top-quality edamame has a thick layer of pure white hair, and some black particles are evenly distributed on it, which are spores and a sign of mature edamame. Hairy tofu is a well-known vegetarian delicacy in Anhui. It is generally called Huangshan hairy tofu or Huizhou hairy tofu. As the name suggests, it is mainly made of edamame curd, which is a special product in Shexian, Tunxi, Xiuning, Yixian, Qimen, and Wuyuan in Huizhou. After being fried, it is served with green onion, ginger, sugar, salt, meat brot...
