Problems solved by technology

[0007] The main technical problem to be solved by the present invention is to overcome the poor elasticity and hardness of the hemp tofu, poor taste, poor overall texture and poor texture of the hemp tofu caused by the inability to form a stable network gelling system when heating and coagulating the hemp tofu with hemp seeds as raw materials. Inhomogeneous, brittle and other serious defects, a preparation method of hemp tofu is provided, which uses the integration of hemp seed protein thermal polymerization and glutamine transaminase cross-linking technology, effectively solving the problem of heating hemp tofu. Coagulation cannot form a stable network gelling system, the prepared hemp tofu has good elasticity, is not easy to break, has a good taste and good water holding capacity

[0047] (3) Thermal coagulation: Hemp milk is slowly heated to 75°C in a boiling water bath for 30 minutes, then cooled to 45°C in a water bath;

[0048] (4) TG enzyme cross-linking: adding 1‰ of the total amount of hemp protein to activate TG enzyme (16000u / g) at 50°C in advance, and keeping it at 50°C for 60 minutes to solidify;

[0049] (5) Extrusion molding: inject the curd into the mold, and the pressure is 0.8MPa and pressed for 25min to form;

[0050] (6) Pack the shaped hemp tofu and pasteurize it at 65-85° C. for 20-30 min...

Embodiment 2

[0051] The preparation of embodiment 2 hemp tofu

[0052] (1) Pre-swelling: select the mildew-free shelled hemp seeds, wash them and soften them with steam, and the steam pressure used is 4MPa;

[0053] (2) Refining: Defining the fully swollen hemp seeds and water at a ratio of 1:5 (without removing slag) to obtain hemp milk;

[0054] (3) Thermal coagulation: Hemp milk is slowly heated to 80°C in a boiling water bath for 10 minutes, then cooled to 50°C in a water bath;

[0055] (4) TG enzyme cross-linking: adding 3‰ of the total amount of hemp protein to activate TG enzyme (16000u / g) at 50°C in advance, and keeping it at 50°C for 90 minutes to solidify;

[0056] (5) Extrusion molding: inject the curd into the mold, and the pressure is 0.8MPa and pressed for 15min to form;

[0057] (6) Pack the shaped hemp tofu and pasteurize it at 65-85° C. for 20-30 minutes.

Abstract

The invention discloses a preparation method of China-hemp tofu and a product of the preparation method and belongs to the field of preparation of the China-hemp tofu. The preparation method of the China-hemp tofu comprises the following steps of (1) mixing China-hemp seed kernels and water, and refining a mixture into a pulp to obtain a China-hemp milk; (2) heating the China-hemp milk for heat coagulation, and then performing cooling; (3) adding TG enzyme in a cooled coagulation product for crosslinking coagulation to obtain curd; and (4) performing compression molding on the curd to obtain the China-hemp tofu. In the preparation method provided by the invention, by taking full cream China-hemp seed kernels as a raw material, the full cream China-hemp seed kernels are heated at 77-78 DEGC to enable China-hemp globulin to generate preliminary thermal polymerization, and the crosslinking integration effect of the TG enzyme is combined on the basis, so that the problem that the China-hemp tofu coagulates without forming a stable network cementitious system during heating is effectively solved, and a China-hemp tofu product which is uniform in elasticity, moderate in hardness, good in formation, difficult in crushing and good in taste and water retention and has a nut flavor is acquired and is particularly suitable for patients with a heart disease and people with menstrual disorder, gluten intolerance and the like to eat.

Description

technical field [0001] The invention relates to a preparation method of hemp tofu and products thereof, in particular to a method for preparing hemp tofu by coagulating heat and TG enzyme, and belongs to the field of hemp tofu preparation. Background technique [0002] Hemp is commonly known as marijuana. Internationally, varieties with a tetrahydrocannabinol (THC) mass fraction lower than 0.3% are called industrial hemp. After 2005, China called hemp; Chinese hemp has a long history of planting and has a wide and large area. The largest producer and exporter of hemp seeds in the world today. The shelled hemp seeds contain about 30% protein, 48% oil, 11% carbohydrates and 6% minerals; because the ratio of linoleic acid and linolenic acid in hemp seeds is close to 3:1, This ratio is consistent with the normal metabolism of the human body. It is the best for human health and is regarded as an important source of high-grade oil. At the same time, studies have found that hemp s...
