Problems solved by technology

However, since the dry state of vitamin C is relatively stable, non-volatile, and cannot play a role in a non-solution environment, it is rarely used in the preservation of fresh fruits and vegetables.

Embodiment Construction

[0010] (1) Use alumina molecular sieves, activate at 250-700 degrees for 0.5-3 hours, put them in a desiccator and cool to room temperature.

[0011] (2) Dissolve 100-500 grams of vitamin C in 100-3000 ml of water, dissolve completely, then pour into 100-3000 grams of activated and cooled alumina molecular sieves and mix well.

[0012] (3) Put the mixture into a vacuum oven and dry it at 30-60 degrees.

[0013] (4) Grinding to a particle size of 1-4mm after drying.

[0014] The material prepared through these steps can be used in the refrigerator to delay the cooking and aging of food. It can also be used as an antioxidant in cosmetics. Of course, its scope of use is not limited to refrigerators and cosmetics. It can be used alone or in combination with other substances. Those of ordinary skill in the technical field should recognize that the above-mentioned embodiments are only used to illustrate the present invention, rather than to limit the present invention. For examp...

Abstract

The invention relates to a method for preparing materials which can slowly release vitamin C. The method is that vitamin C is dissolved into a porous adsorption vector, then solvent is dried in a swing way, finally power is crushed into needed particle size. The powder materials prepared by the method has the efficacy of slowly releasing vitamin C, takes the effects of deferring food oxidation, supplementing vitamin C under non-contact condition. The method can be applied to refrigerators, air-conditions and other places which need vitamin C, has good economic value and market prospects.

Description

Technical field: [0001] The invention relates to the preparation of a material capable of slowly releasing vitamin C. Background technique: [0002] Vitamin C is easily soluble in water and is relatively stable in a dry state. It can combine with oxygen to become an oxygen scavenger and inhibit the oxidation of oxygen-sensitive food components. Vitamin C can participate in the metabolism in the human body and is a very safe antioxidant. Vitamin C is often used for the anti-oxidation of food, but for fresh fruits and vegetables, it is generally only refrigerated. Fresh fruits and vegetables will slowly release ethylene gas, which makes the fruits and vegetables self-ripe and aging. Antioxidants can react with ethylene to make fruits and vegetables self-ripe and delay aging. Among antioxidants, vitamin C is the first choice in terms of safety and cost performance. However, because vitamin C is relatively stable in dry state, non-volatile, and cannot play a role in a non-so...
