Food Additives are substances added to food. Some additives have been used for centuries. With the advent of processed foods in the second half of the twentieth century, many more additives have been introduced, of both natural and artificial origin.

First, do feed potato tubers and potato residues can feed livestock and poultry. According to experiments, feeding a pig with 50 kilograms of potatoes can increase meat by 2.5 kilograms; feeding cows can produce milk by 40 kilograms or cream by 3.5 kilograms. Each chicken is fed an average of 71 grams each of chopped cooked potatoes and mixed feed. The annual production of eggs can increase by 30 to 50, and 20 kg of concentrated feed can be saved.
Second, the extraction of starch per 100 kilograms of potatoes can generally produce 12.15 kg of starch. The extraction process is relatively simple. The potatoes are washed first, followed by mechanical crushing, grinding, sifting, separation of sludge, and finally dewatering and drying.
Third, the processing of cooked food can be processed potato chips, potato strips, mashed potatoes and deep-fried all kinds of packaged foods and puffed foods. Among them, fried potatoes are delicious and nutritious and are very popular among people. The processing process is: choose fresh, high-quality potatoes to wash, and then peeled by mechanical or chemical methods, cut into thin slices by a rotary slicer, then fry in a 190 °C oil pan, add salt or sugar seasoning, Packed into a product for sale.
Fourth, the production of brown sugar, potato starch or powder residue can be made of sugar. In the former, the starch is first made into starch milk, which is then liquefied, and then the starch is hydrolyzed and saccharified by the addition of amylases, and the pulp is filtered; the latter is required to grind the powder slag, add an appropriate amount of glutinous and clear water, steam and saccharification.熬 Serve.
Fifth, the production of calcium citrate calcium citrate is an intermediate product of citric acid, can be further processed into citric acid, and citric acid is an important raw material for food, chemical, pharmaceutical, machinery, textile and other industries. Each ton of potato powder residue can produce 1 ton of calcium citrate. The process flow is: powder residue crushing - adding water to sieving - cooking and sterilizing - replenishing water and adding bacteria - fermenting - immersing - heating deproteinization - precipitating impurities - neutralization plus calcium - product drying - packaging products. In addition, potatoes and their by-products can be used to make wine or to make alcohol, monosodium glutamate, and the like.
The advantages of food additives are these followed:
1. Improve the appearance of food.
2. Keep and enhance the nutrition value of food.
3. Increase the variety and conveniences of food.
4. Miantain freshness and prolong shelf life.
5. Provide leavening or control acidity and alkalinity.
Comprehensive utilization of potato
Potato is one of China's major cash crops and is cultivated everywhere. In addition to people eating as rations and vegetables, there are still plenty of resources available for comprehensive utilization that can further increase their economic value. The main methods for processing and utilizing potatoes are:
