Abstract

The invention relates to a carrot bifunctional enzyme-containing fruit and vegetable fresh-keeping agent which comprises the components with content: 40-80mg of carrot bifunctional enzyme, 1-10mg of polysaccharide, 0.01-1mg of preservative, 0.1-5mg of surface active agent, 0.01-1mg of antioxidant, 1-20ml of edible ethanol and 50-100ml of water. The fresh-keeping agent is capable of effectively killing fungus leading fruits and vegetables to decay and preventing water loss, and is simple in formulation and good in fresh-keeping and green-keeping effects.

Description

technical field [0001] The invention relates to the field of antistaling agents, in particular to a fruit and vegetable antistaling agent containing radish bifunctional enzymes. Background technique [0002] Fruits and vegetables are necessities in people's lives, but because of their strong seasonality and regionality, it is currently the domestic hot topic of foreign research. [0003] The epidermis and epidermis of fruits and vegetables are covered with a layer of waxy substance, which can prevent the invasion of microorganisms, so the internal tissues of normal fruits and vegetables are generally sterile. However, when the epidermal tissue of fruits and vegetables is stabbed by insects or other mechanical damage, microorganisms will invade and reproduce, thereby promoting the rot and deterioration of fruits and vegetables, especially fruits and vegetables with high maturity are more likely to be damaged. In addition, the material composition of fruits and vegetables is...
