Abstract

The invention belongs to the technical field of fruit preservation, and discloses preparation and application of a natural preservative for nectarine. In the natural preservative, the main active ingredients are tea polyphenol and tea saponin, and vitamin C or oxalic acid is taken as a synergist; and based on g / L and scalar quantity, the natural preservative comprises the following components: 9 to 11 parts of tea polyphenol, 11 to 13 parts of tea saponin, 0.5 to 0.8 part of organic acid and the balance of water. Compared with the common chemical preservative carbendazim, the natural preservative can inhibit the reduction of hardness of nectarine fruits, reduce the respiratory intensity of the nectarine fruits, inhibit the increase of the permeability of the nectarine fruits and the invasion of pathogenic microorganisms, induce resistance enzymes to improve activity, reduce the rot and deterioration of the nectarine fruits and prolong the quality guarantee period of the nectarine fruits.

Description

technical field

[0001] The invention relates to the technical field of fruit preservation, in particular to a nectarine preservative developed by using tea polyphenols and tea saponin as main components. The shelf life of the fruit. Background technique

[0002] Nectarines are bright in color, crispy in flesh, sweet and sour, and rich in nutrition, so they are deeply loved by consumers. However, peaches have strong respiration, rapid ripening, and poor storability. In addition to the high temperature and rainy season during the harvesting season, it is easy to be infected and rotted by various fungal diseases such as soft rot and brown rot after harvesting. Therefore, certain anti-corrosion and fresh-keeping measures must be taken to meet market demand.

[0003] Refrigeration combined with the use of chemical fungicides is currently the main method for keeping nectarines fresh. Low temperature can inhibit the growth of some pathogens and reduce the occurrence of some disea...
