Problems solved by technology

Because the traditional process of preparing frozen tofu is cumbersome and labor-intensive, it is particularly important to propose a time-saving and labor-saving method for preparing frozen tofu.
[0004] Because frozen tofu will also melt under natural conditions, there is little research on its thawing method. However, for frozen foods, the thawing method directly affects product quality, and its importance is no less than the freezing process, so it is necessary to study it
At present, the traditional thawing methods of various hot pot restaurants and shabu-shabu restaurants are natural thawing or water bath thawing, which takes a long time and reproduces many microorganisms, which cannot guarantee the safety of the product. If microwave thawing can be used, the frozen tofu can be quickly and hygienically It is a good way to deliver to consumers

Embodiment 1

[0027] Fully mix 6% soybean plant protein with 4% sucrose and water to obtain an emulsion, heat it to 85°C, keep it warm for 7 minutes, and then add 0.2% soybean lecithin and 4% volume percent to it. % soybean oil, homogenize under the condition of 20Mpa after mixing evenly, add the calcium sulfate that the mass percentage is 0.20% and the gluconolactone that the mass percentage is 0.40% in the liquid after the homogenization, fully stir and put into In the mold, keep warm at 75°C for 27 minutes to prepare tofu products, put them into the refrigerator, freeze at -15°C for 3 hours, and then store them at -18°C for 18 days. After the frozen storage operation, microwave thawing under the condition of 500W for 30s to obtain the frozen tofu product.

Embodiment 2

[0029] Fully mix 8% soybean plant protein with 5% sucrose and water to obtain an emulsion, heat it to 90°C, keep it warm for 10 minutes, and then add 0.3% soybean lecithin and 6% volume percent to it. % soybean oil, homogenize under the condition of 30Mpa after mixing evenly, add the calcium sulfate that the mass percentage is 0.35% and the gluconolactone that the mass percentage is 0.50% in the liquid after homogenization, fully stir and put In the mold, keep warm at 85°C for 30 minutes to prepare tofu products, put them into a blast freezer, freeze at -10°C for 4 hours, and then store them at -16°C for 19 days. After the freezing storage operation, microwave thawing under the condition of 300W for 60s to obtain the frozen tofu product.

Embodiment 3

[0031] Mix 10% soybean plant protein with 5% sucrose and water to obtain an emulsion, heat it to 90°C, keep it warm for 11 minutes, then add 0.5% soybean lecithin and 8% volume % soybean oil, homogenize under the condition of 40Mpa after mixing evenly, add the calcium sulfate that mass percentage is 0.35% and the gluconolactone that mass percentage is 0.60% in the liquid after homogenization, fully stir and put into In the mold, keep warm at 85°C for 33 minutes to prepare tofu products, put them into the refrigerator, freeze at -10°C for 3 hours, and then store them at -16°C for 19 days. After the freezing storage operation, microwave thawing under the condition of 200W for 60s to obtain the frozen tofu product.

Abstract

The invention relates to a production method of novel frozen bean curd. The production method includes: sufficiently mixing vegetable protein, sucrose and water to obtain turbid emulsion, heating to 85-95 DEG C, and keeping the temperature for 7-12 minutes; mixing soybean lecithin and vegetable oil, adding the mixture into the turbid emulsion, and emulsifying and homogenizing to obtain emulsion; adding calcium sulfate and glucolactone, sufficiently stirring, placing into a mould, and keeping the temperature of 75-85 DEG C for 27-33 minutes to obtain bean curd; curing the bean curd taken out through freezing, and sufficiently unfreezing the bean curd taken out through microwaves to obtain the frozen bean curd. The frozen bean curd produced by the method is even in porosity, good in flexibility and good in taste.

Description

technical field [0001] The invention belongs to the technical field of food processing, and in particular relates to a preparation method of a novel frozen tofu. Background technique [0002] Soybean protein is a complete protein, which contains essential amino acids required for the normal development of infants and children, and is an ideal protein source for increasing food nutrition. Like milk and egg proteins, soy protein has a digestibility-corrected amino acid score (PDCAAS) of 1.0, the highest score a protein can achieve. While soybean protein provides nutrition, soybean protein containing high content of soybean isoflavones can effectively relieve hot flashes and reduce the incidence of breast cancer and colon cancer. [0003] Tofu is a kind of traditional soybean food in our country. It is high in quality, cheap in price and rich in nutrition, but it is not suitable for preservation and is easy to deteriorate. Frozen tofu refers to the product after tofu is quick...
