Problems solved by technology

Although long-term consumption of pork containing chemical preservatives is non-toxic to the human body, chemical preservatives will affect the quality of fresh meat, destroy the original characteristics of meat, and have poor freshness preservation effect. Therefore, we have designed a method to improve the freshness of pork Processing methods to solve the above problems

Abstract

The present invention discloses a processing method for improving freshness of pork. The food processing comprises the following steps: pork of slaughtered pigs is washed, water of the washed pork iscontrolled, the pork is cut into blocks, heat of the cut pork is dissipated to room temperature, the heat-dissipated pork is put in a freezing chamber, the pork is subjected to an aging process at a temperature of 2-3.5 DEG C until pH value of the pork is reduced to 5.4-5.8, a preservative is prepared, an ultrasonic treatment is conducted to enable the preservative to penetrate into the pork, thepork is subjected to a modified atmosphere packaging, and the packaged pork is put in the freezing chamber with a freezing point temperature to be stored. The preparation method can delay deterioration of the aged pork and maintain freshness, color and luster of the aged pork for a long time, the pork has functions of clearing heat, removing dampness, benefiting the spleen and caring health at thesame time, and the preparation method is also simple and easy to operate and suitable for mass production.

Description

technical field [0001] The invention relates to the technical field of food processing, in particular to a processing method for improving the freshness of pork. Background technique [0002] Pork, also known as porridge, is the meat of one of the main domestic animals, the pig family pig. Its nature and taste are sweet and flat, rich in protein and fat, carbohydrates, calcium, iron, phosphorus and other nutrients. Pork is the main non-staple food in daily life. It has the functions of tonifying deficiency and strengthening the body, nourishing yin and moistening dryness, and plumping the skin. Anyone who is weak after illness, postpartum blood deficiency, and yellow and thin, can be used as a nutritious product. my country is a big consumer of pork, and it is very important to develop fresh-keeping technology for meat products. Especially the advent of chilled meat in recent years has put forward higher requirements for pork fresh-keeping technology. However, the shelf l...
