Problems solved by technology

At present, the natural red pigments used in crab sticks include cochineal red pigment, monascus red pigment, etc., but these red pigments generally only have the effect of protecting color, and the effect of freshness preservation is poor.
[0005] Chinese patent document CN104621230A discloses a fresh-keeping and color-protecting atomizer for fresh foods such as chicken wings, pork, and beef. The effect makes lycopene dissolve in water to form an atomizing agent and form a protective film on the surface of fresh meat to reduce water evaporation, but the effect on color protection is not obvious
Chinese patent document CN1053949A discloses a water-soluble emulsified lycopene vegetarian coloring agent and a preparation method thereof, and the coloring effect of the product obtained by this scheme is not good when applied to surimi products

Abstract

Disclosed is a lycopene food coloring agent with a fresh-keeping function, which is characterized in that, in parts by weight, it is prepared from raw materials comprising the following components: 1-3 parts of lycopene crystals, 5-20 parts of emulsifier, 0.5-5 parts of antioxidant, 60-70 parts of glycerin, and 10-20 parts of water. The food coloring agent is prepared by mixing raw materials, emulsifying and grinding. The obtained lycopene coloring agent has moderate particle size, suitable color tone for the coloring of surimi products, strong coloring power, bright colors, and the effect of stimulating myoglobin, making the surimi products bright in color and appear fresher, and also has the function of keeping freshness. Function, can kill some food microorganisms, so as to keep the food fresh and increase the shelf life.

Description

technical field [0001] The invention relates to the field of food industry, in particular to a lycopene colorant with a fresh-keeping function and a preparation method thereof. Background technique [0002] Lycopene is one of the carotenoids. Its molecule contains many double bonds and has strong antioxidant activity, which can avoid the antioxidant damage of cells and prevent the occurrence of cancer. Secondly, lycopene can also prevent the heart and brain. The occurrence of vascular disease, as well as anti-aging and other functions. [0003] Lycopene is a fat-soluble red pigment. When it is applied to the surface of food such as meat products, it can not only make fresh meat products bright in color, but also play a moisturizing and fresh-keeping function, and increase the shelf life of products. However, due to the water insolubility of lycopene, the application of lycopene in food is greatly limited. [0004] Crab sticks and other surimi products need to be coated wit...
