Problems solved by technology

However, there are few reports on the fresh-keeping methods of kiwi fruit pre-harvest treatment. There are mainly pre-harvest spraying of calcium, potassium, chlorine dioxide and other treatment methods. In production practice, there is still no feasible special fresh-keeping technology for pre-harvest kiwi fruit

Abstract

The invention discloses a kiwi fruit preservation method, and belongs to the technical field of fruit preservation. According to the method, the step of spraying composite spraying agent to kiwi fruits before harvesting and the step of treating after harvesting are organically combined, wherein the composite spraying agent is characterized in that 50-300 mg of organic calcium, 10-50 mg of auxin additive and 1-20 g of chitosan oligosaccharide substance are contained in each liter of water. The preservation method disclosed by the invention can be used for delaying the descent rate of the hardness of the kiwi fruits, effectively inhibiting the pectin polygalacturonase (PG) activity, and postponing the peak of respiration rate of the kiwi fruits, so that the rotting rate after the fruits are picked is effectively reduced, and the storage life of the kiwi fruits is remarkably prolonged.

Description

technical field [0001] The invention belongs to the technical field of fruit preservation, and in particular relates to a method for preserving kiwi fruit. Background technique [0002] Actinidia is a general name for perennial plants of the genus Actinidia in the family Actinidia. It is a perennial vine and is an important fruit resource. Kiwifruit pulp is sweet and sour, nutritious, rich in VC, and has high health value. Kiwifruit also contains functional ingredients such as dietary fiber, polysaccharides, flavonoids, polyphenols, and a variety of amino acids and mineral elements that are beneficial to the human body. , so it has the reputation of "super fruit". [0003] Patent No. CN201410220733.6 "A Preservative for Kiwifruit Fruit and Its Application Method" proposes that kiwifruit is a typical climacteric berry, which is extremely sensitive to temperature and ethylene. It is extremely perishable, and the post-harvest loss rate is as high as 35%. It is known as "soft ...
