Problems solved by technology

Due to the poor texture of pigskin itself, pigskin is rarely used in the leather industry, and the pigskin produced by the slaughterhouse cannot be processed into leather after blanching, so the processing and utilization of pigskin has dropped significantly in recent years the trend of
In addition, due to the unacceptable peculiar smell, bad taste, low digestibility, and inconvenient processing of pigskin, it is often thrown away and rarely used directly, resulting in a large backlog of pigskin, and the The nutritional value and function have not been fully utilized
Pigskin raw materials are rich in resources, but the application area is relatively narrow, and it is impossible to use pigskin raw materials on a large scale, so that the comprehensive utilization rate of pigskin is not high, which restricts the development of pigskin processing industry
[0006] 2. Pig skin deep processing technology failed to break through the constraints of modern eating habits
The reason for this situation, in the final analysis, is that the existing food processing technology cannot break through the constraints of modern eating habits. Innovative technology is needed to produce delicious and nutritious pigskin products by using advanced

Embodiment 1

[0050] see figure 1 , the processing method of the recombined puffed pigskin in this embodiment sequentially includes a raw material pretreatment step, a pickling step, a rinsing step, a secondary trimming step, a mincing step, a biological enzymatic hydrolysis step, a cooking inactivation step, and a high-speed chopping step , Filling forming step, freezing step, slicing step, drying step, wet equalization step, frying step, deoiling step, sprinkling step, baking step and packing step, specifically as follows.

[0051] (1) Raw material pretreatment step.

[0052] Cut off the dirt and residual minced meat on the raw pigskin, scrape off the residual oil under the skin until the pores of the skin are exposed, then add the trimmed pigskin to clean water and wash it for 4 times until the water is colorless and free of impurities. Pre-treat the pork skin. In the present invention, the trimmed pigskin is usually washed for 3 to 5 times by adding clean water.

Abstract

The invention relates to a machining method of recombined puffed pigskin. Currently, a machining method for manufacturing the puffed pigskin by utilizing crushed pigskin leftover materials does not exist. The machining method comprises the following steps of: pre-treating raw materials; pickling; picking in a pickling solution for 10-12 hours, wherein the pickling solution comprises the components of water, sodium hydroxide and potassium phosphate; rinsing; carrying out secondary finishing; crushing; carrying out biological enzymolysis: adding pigskin grains, alkaline protease and saline water into an enzymolysis fermenting pot, agitating uniformly and keeping the pH (Potential of Hydrogen) value of the system to be at 7-8 at a temperature of 40-55 DEG C, and then agitating and carrying out enzymolysis at an interval for 4-6 hours; cooking and inactivating; carrying out high-speed chopping: adding pigskin protein liquid into a chopping and mixing machine when the pigskin protein liquid is hot, and then adding glutamine transaminase, aspartame, I+G, soybean isolated protein, modified starch, mashed potato and water to carry out chopping and mixing; filling and molding; freezing; slicing; and drying. According to the machining method, the crushed pigskin leftover materials can be utilized to manufacture the puffed pigskin with a comfortable mouth feel and a special flavor.

Description

technical field [0001] The invention relates to a processing method of recombined puffed pigskin, in particular to a processing method of using pigskin as a raw material and using bio-enzymolysis technology to recombine the raw material of pigskin and then make puffed leisure pigskin food, which belongs to puffed food processing field. Background technique [0002] my country is a big meat producing country, and its output has been ranked first in the world for more than ten years. In 2010, my country's pork output was 50.7 million tons, and the total meat output value of my country has accounted for 3.7% to 4.7% of GDP, and 33% to 40% of the output value of the primary industry. One of the pillar industries of the national economy. As a by-product of pig slaughtering and processing, pig skin accounts for about 10% of the total weight of pig carcasses. Pig skin resources are quite abundant, and it is a material with abundant sources and low price. [0003] The main compone...
