Embodiment Construction

[0020] 1. Production process:

[0021] 1) Raw material pretreatment: Collect duck blood immediately when meat duck is slaughtered, take 300g duck blood, and then add 100g of 0.9-1.0% trisodium citrate aqueous solution to duck blood within 8 minutes, stir well and filter with double gauze , Collect the filtrate, refrigerate at 4 ℃ temperature conditions, standby.

[0022] 2) Broken wall treatment: Duck blood is subjected to 20±5Mpa, 20±1℃ high pressure homogenization treatment to make cell fragments less than 100nm, and then 40±5kHz, 15±1℃ ultrasonic treatment for 30±2min.

[0023] 3) Compound mixing: Weigh 0.40 g of sodium alginate, 0.60 g of chitosan, 0.04 g of glutaminase, 1.20 g of white sugar, and 0.40 g of monosodium glutamate into the broken duck blood, stir and mix them.

[0024] 4) Vacuum degassing: perform vacuum degassing at a low temperature of 10±1℃ (the vacuum degree is 0.01MP), and keep it for 5±1min.

[0025] 5) Blood coagulation cross-linking and shaping: inject 40g cal...

Abstract

The invention relates to a method for producing composite bean curd with duck blood and belongs to the technical field of deep processing of agricultural products. The method comprises the following steps of: raw material pretreatment of collecting duck blood, anticoagulation, filtering and the like; treatment of high-pressure homogenization and ultrasonic wall breaking, composite mixing of flavoring and a water retention agent, vacuum degassing, calcium chloride-sodium chloride aqueous solution coagulation crosslinking and sizing, and a sealing and pasteurization process. The process greatly improves the quality and safety of the bean curd with duck blood, realizes industrialized production of the duck blood, and well solves the problems that nutritional ingredients of the bean curd with duck blood have low digestion and utilization rate; the texture is not exquisite enough and the section is coarse. An obtained product has smooth surface, black red lustre, leveled section, no pores and delicious flavor; and compared with a conventional method for processing the bean curd with duck blood, the method has the advantages of easy absorption of rich nutrition, high quality, health and safety and remarkable economic benefit.

Description

Technical field [0001] The invention relates to a method for producing wall-broken compound duck blood tofu, which belongs to the technical field of agricultural product processing. Background technique [0002] Duck blood is cold and salty, has the effect of nourishing blood, clearing heat and detoxifying. "Materia Medica Biandu" records: Duck blood specializes in detoxification, but it requires hot drink to solve it. In addition to about 85% of water, duck blood contains about 16% of protein, rich in mineral elements such as iron, zinc, potassium, and a variety of vitamins. In addition, it also contains a variety of biologically active substances with high nutritional value. Duck blood can treat dysentery, vomiting blood due to strain, hot flashes in women, and white dysentery. For vandan stone, arsenic, vegetable poisoning, etc., oral administration with duck blood has a good effect. Duck blood can also treat hot blood, stroke and dizziness, and prevent gastrointestinal tum...
