The main feed for silkworm is mulberry leaf. Because the quality of mulberry leaf differs greatly in different seasons, it has a great influence on the yield and quality of silkworm cocoon. If the nutritional supplements for summer and autumn silkworm breeding, the output can be increased by 10% -20%, the formula technology is introduced as follows: First, add food formulations and feeding methods 1. Glucose solution additive. In the silkworm rearing period, in the case of continuous rainy weather, the mulberry leaf is lighter due to lack of light and the texture is tender, the water content is high, and the carbohydrate is reduced. At this time, the mulberry leaf reclaimed by the 5% glucose solution can be sprayed, and the silkworm can be fed after the silkworm is dried. Can greatly ease the decline in quality caused by the decline in the quality of enamel and pods. 2. Soybean milk additives. In the case of long-term drought and no rain in summer and autumn, mulberry leaves tend to age hard and lack sap. At this time, a better way is to use the boiled cold soya milk to spray Mulberry leaves to feed silkworms. Add 1-2 times during the day to the 4-5 day old silkworm. Soybean milk production methods: Wash the soybeans to miscellaneous, according to the proportion of soybeans and water 1:15 dip fat after refining to slag, boiled and cooled after consumption, with every 1000 grams of soybean milk spray mix 15 kg of mulberry leaves is appropriate. 3. Urea liquid additive. The mulberry leaves were sprayed with 0.5%-1% urea solution, dried and fed with silkworms. Starting from the third day of the fifth-day silkworm, adding one serving each morning and afternoon can significantly increase silkworm cocoon production. Second, note 1. The formula water should be clean cold water, and the concentration of the added food should not be arbitrarily increased. 2. The mulberry leaves that have been sprayed with nutritious additives cannot be stored for a long time and must be used up on the same day of preparation to prevent deterioration and bacterial growth. Soymilk is more easily fermented and deteriorated, so it is not appropriate to produce more milk each time. 3. The mulberry leaves that have been supplemented with nutrients when the weather is hot and dry may not be allowed to dry and the rainy weather must be air-dried and then fed. 4. Urea urea must meet the standard, small factories can not use the urea to meet the standard, to prevent biuret poisoning.
Preservative Agent
Preservatives refer to natural or synthetic chemical ingredients. When used in cosmetic formulations, it can effectively inhibit microbial growth or corruption caused by chemical changes to ensure the safety and stability of the product during its shelf life.
There are roughly three types of anti-corrosion principles for preservatives:
1. Interfering with the enzyme system of microorganisms, destroying their normal metabolism, and inhibiting enzyme activity.
2. Causing solidification and denaturation of microbial proteins, interfering with their survival and reproduction.
3. Changing the permeability of the cell plasma membrane, inhibiting the elimination of enzymes and metabolites in the body, leading to its inactivation.
