Problems solved by technology

At present, many duck slaughtering enterprises directly discharge duck blood in the form of waste in the production process, wasting resources and polluting the environment; some enterprises process it, but the processed products are mainly in the form of blood meal and traditional blood tofu. to a lesser extent
[0003] Because duck blood is easy to coagulate, difficult to collect, and easy to pollute, the utilization rate of duck blood in my country is relatively low, and the duck blood processing industry has not yet formed a certain scale.
At present, the most common duck blood product on the market is duck blood tofu, which is mainly produced and processed by hand workshops. The quality of the products produced is poor, unstable, with pores, dark color, short shelf life, and poor edible quality.

Abstract

The invention belongs to the field of comprehensive utilization of food resource byproducts and relates to a duck blood deep processing production method, in particular to a duck blood curd productionmethod. In a duck blood collection process, a certain quantity of an anti-coagulation agent is added to prevent duck blood coagulation and keep duck blood in a fresh plasma state. Before eating, a coagulant is added to enable coagulation of duck blood. By adoption of the duck blood curd production method, high-quality duck blood curd bright in color and tender and smooth in taste can be produced,the duck blood utilization rate is increased, and high economic benefits and social benefits are created.

Description

Technical field: [0001] The invention relates to a production method for deep processing of duck blood, in particular to a production method of duck blood tofu, which belongs to the field of comprehensive utilization of by-products of food resources. technical background: [0002] The total amount of duck blood in my country is large. In recent years, the number of meat ducks slaughtered in my country has remained at about 3 billion. According to the calculation of the blood volume collected from each duck during the processing of meat ducks, the amount of duck blood produced can reach 300,000 tons. A very important animal protein resource. Duck blood is rich in nutrients, rich in protein and essential amino acids, as well as carbohydrates, fats, minerals, vitamins, enzymes and some active peptides. At present, many duck slaughtering enterprises directly discharge duck blood in the form of waste in the production process, wasting resources and polluting the environment; some...
