Embodiment 1

[0021] A composite natural antistaling agent for chilled meat, which consists of the following components in parts by weight: 3 parts of tea polyphenols, 3 parts of chitosan, 4 parts of nisin, 6 parts of natamycin, and 3 parts of lysozyme 5 parts of oregano essential oil, 10 parts of vitamin C, 10 parts of vitamin E, 16 parts of erythrobonic acid, 18 parts of spice extract, 160 parts of water;

[0022] The preparation method of the spice extract is as follows: the spices with the weight ratios of 16 parts of ginger, 14 parts of garlic, 20 parts of cinnamon, 18 parts of cardamom, 7 parts of cloves and 5 parts of rosemary are respectively dried, pulverized and mixed evenly, and added Extract with 95% ethanol, the ratio of solid to liquid is 1Kg: 20L, extract with traditional Chinese medicine ultrasonic extraction machine for 2 hours, remove the filter residue, collect the supernatant, concentrate to 1.7-1.9 times the volume by rotary evaporation in a reduced-pressure water bath, ...

Embodiment 2

[0025] The fresh-keeping test was compared with pork special fresh-keeping agent produced by Hubei Yuancheng Pharmaceutical Co., Ltd.

[0026]On April 7, 2015, a test on the freshness effect of different preservatives on chilled pork during storage was carried out. The longissimus dorsi of fresh pigs was removed from the fascia on a clean and sterilized chopping board, and cut into pieces of uniform size and mass (200g±10 ) g meat pieces were randomly divided into 3 groups, with 5 repetitions in each group. Groups 1 and 2 were treated with the composite natural antistaling agent for chilled fresh meat of the present invention in Example 1 and the special antistaling agent for pork provided in Example 2 respectively, and group 3 used distilled water as a control test. The three groups of meat pieces were soaked for 2.5 minutes, and after standing for 15 minutes, they were accurately weighed, put into aseptic bags, vacuum-packed, and placed in a (4±1)°C freezer for storage for l...

Abstract

The invention relates to a composite natural fresh-keeping agent for cold fresh meat and application of composite natural fresh-keeping agent. The composite natural fresh-keeping agent for the cold fresh meat is characterized by comprising tea polyphenol, chitosan, nisin, natamycin, lysozyme, oregano essential oil, vitamin C, vitamin E, erythorbic acid, a spice extract and water in certain proportions by weight, wherein the spice extract is obtained by extracting ginger, garlic, cinnamon, cardamom, clove and rosemary in certain proportions by weight through ethanol extraction. The composite natural fresh-keeping agent for the cold fresh meat is prepared from biological-source raw materials by a simple preparation method, has the advantages of non-toxicity, safety, broad antibacterial spectrum and the like, is convenient to operate during using and prominent in fresh-keeping effect, and has an important industrial value.

Description

technical field [0001] The invention relates to a composite natural preservative for chilled fresh meat and its application, which belongs to the technical field of chilled fresh meat preservation, and in particular relates to a compound natural preservative for chilled fresh meat, which is prepared by using biological source raw materials, and the preparation method is simple, and has the advantages of non-toxicity, safety, and wide antibacterial spectrum. , easy to operate during use, outstanding fresh-keeping effect, and a compound natural fresh-keeping agent for chilled fresh meat with important industrial value and its application. Background technique [0002] Chilled fresh meat means that the slaughtered carcass is rapidly cooled, so that the temperature of the carcass (the center of the hind leg meat) drops to 0-4°C within 24 hours, and it is kept at 0-4°C during the subsequent processing, distribution and sales. Range of fresh meat. In the process of chilled meat p...
