Storage method

Packaging in food-grade plastic bags and woven bags. Store in a cool and dry place.

Synthesis method

1. A large amount of sucrose comes from cane sugar and beet. Sugar cane contains about 15-20% sucrose, and beet contains 10-17%. There are also different contents in various other fruits, seeds, leaves, flowers, and roots. Squeeze out the liquid from sugar cane or extract sugar juice from sliced beets with water. Use lime clarification method or combined with sulfurous acid filling method to remove impurities in the sugar juice. After filtration, vacuum evaporate the filtrate to thicken, recrystallize and separate to obtain jaggery, and then Refined sugar is obtained through decolorization and recrystallization.

2.Dissolve ordinary sucrose in water, filter, and then evaporate under reduced pressure. Pure product available.

Purpose

1. Sucrose is the most commonly used sweetener. The annual production and consumption of sucrose in the world is about 80 million to 100 million tons. It can also be used as chemical raw materials, such as the synthesis of sucrose lipids, etc.

2. Used for the preparation of analytical reagents and biological nutrients.

3. Sucrose is the most common edible sugar and is also used to make citric acid, caramel, invert sugar, transparent soap, etc. , sucrose can inhibit bacterial growth at high concentrations and is used in medicine as a preservative, antioxidant and tablet excipient.
