Abstract

The invention discloses a food-grade coloring product applied to the pig raising industry, which is characterized by comprising, by weight, 0.5% -15% of a coloring agent, 40% -80% of water, 10% -30% of a moisture retention agent, 0.1% -20% of a thickening agent, 0.1% -5% of a stabilizing agent and 0.01% -5% of a preservative. The invention also discloses a preparation method of the catalyst. Compared with the prior art, the marking method can mark the raw pig ketone body, has stable coloring, reduces the food safety risk caused by adopting non-food-grade crayon materials when the raw pig ketone body is colored, reduces the problems of pollution of livestock caused by skin contact of related high-risk substances such as mobilizable heavy metals (such as lead, mercury and the like) and polycyclic aromatic hydrocarbon problems (such as naphthalene, pyrene, phenanthrene, benzo [ g, h, i ] perylene and the like), is convenient for cleaning the smearing coloring trace problem and the equipment cleaning problem, and reduces the dust pollution problem of the coloring agent.

Description

Food-grade coloring product applied to pig raising industry and preparation method thereof Technical Field The invention relates to the field of food-grade coloring product manufacturing, in particular to a food-grade coloring product applied to the pig raising industry and a preparation method thereof. Background The pig raising industry is one of the most traditional agricultural raising products, is one of important industries in China agriculture, and with the improvement of the living standard of people and the improvement of the living environment of common people, the pig raising industry in China is changed from the traditional pig raising industry to the modern pig raising industry, and the raising mode, the regional layout, the production mode and the production capacity are all changed obviously. There are many challenges of weak autonomous innovation capability, outstanding food safety problem, high labor cost, import dependence on stock, serious epidemic disease, large environmental protection pressure, deficient feed resources and the like. But also has opportunities of autonomous innovation condition improvement, large international market space, steady increase of domestic market, large government support force and the like. The future development direction is mainly in the aspects of food safety, moderate-scale cultivation, intelligent pig industry, animal welfare, low carbon emission and the like. China is the biggest pork production and consumption market worldwide. According to the data of the national statistical bureau, the number of pigs in 2024 China is 70256 ten thousand, the pork yield is 5706 ten thousand tons, the number of pigs in the stock 42743 ten thousand, the number of sows in the stock 4078 ten thousand can be increased, the yield is ranked third in the last year but is still at a higher level in the last 16 years, and the pig is the largest pork producing country worldwide. According to the comprehensive data of the national statistical office and the United states department of agriculture, the 2024-year Chinese pork consumption is 5795.2 ten thousand tons, accounting for about 50% of the contemporaneous global pork consumption, which is the largest pork consumption country worldwide. Although the gliding state is affected by the earlier stage of beef and mutton price gliding, pork is still in a long-term dominant position in meat consumption in China. According to the data of the national statistical bureau, in 2024, the pork yield of China is 5706 ten thousand tons, accounting for 59.05 percent of the pork yield of 9663 ten thousand tons. The population number and diet structure of our country determine that pork continues to dominate the protein demand of our country for a long period of time in the future. Meanwhile, in the notification about the requirements of standardized animal quarantine inspection witness marks, related mark patterns and the like issued by the office in the agricultural rural area department at 3 months and 20 days, the raw materials meeting the food-grade standard and the raw material materials meeting the national regulations are definitely written, so that pollution to live pig products cannot be caused, and the adoption of food-grade coloring agents as the raw materials of the seal ink becomes a necessary option caused by policies.
