Beet root red pigment is a natural pigment made from edible red beet roots through extraction, separation, concentration and drying. The main component is beet root anthocyanin. Beet root red is a red-purple to dark purple liquid, powdery, and easily soluble Water and aqueous solution are red to purple-red, with bright color.
1. Beet root red has bright color, uniform coloring, no peculiar smell, and good coloring function. Beet root red pigment is widely used in the coloring of beverages, ice creams, some alcohols, candies, pastries, meat products and other foods.
2. It has good coloring properties to food, and since most foods have a pH value between 3.0 and 7.0, and their color does not change in this pH value range, the color of the food when beet root red is used as a food colorant will not be affected by pH. In the production of low-water activity foods, the use of beet root red can receive satisfactory dyeing and long-lasting color effects.
3. Compared with other coloring agents, beet root red is relatively stable during food processing and storage. Beet root red can give food the bright red color of bayberry or rose. Vitamin C is slightly stable in the presence of polysaccharides and can prevent fading in the presence of polysaccharides. It is used for cold fruits that are not affected by heat and light, especially yogurt, milk drinks and strawberry drinks, soft ice and any food.
4. In the study of using beet root red pigment and oligochitosan to remove nitrite in sausages, it is found that chitosan has good water retention ability, but the ability to remove smoke nitrate is relatively hot. Beet root red pigment has a good ability to remove nitrite. Therefore, in the process of sausage production, reduce the general amount of chitosan and supplement it with beet red pigment, which can be used as a coloring agent for sausages and as a sub Nitrate scavenger.
