Problems solved by technology

The earliest "Bingtangxin" apples were launched in the Aksu region of Xinjiang, my country, and then began to rise in Daliangshan, Zhaotong and other places. However, in the past two years, the publicity of this kind of apples has declined. The possible reason is that global climate change has affected these products. The incidence of water-core disease in the district may also be due to the short storage time of "Bingtangxin" apples, which affects the market income.
[0003] At present, there are several main problems in the storage and transshipment of candied apples: 1. During the storage of candied apples, sorbitol is transported and diffused from the candied parts to non-sugar-centred parts; Regulatory effect, the sorbitol in the apple candy center will gradually diffuse into the whole apple, resulting in the disappearance of the candy center, seriously affecting the quality of the apple candy center on the market; 2. During the storage of candy apples, the heart rate of apple candy drops; 3. Storage of candy apples During the period, the sugar index decreased
[0006] Patent document CN110803957A discloses a kind of anti-digestion physiological regulator and treatment technology of apple candy heart. It is a kind of amino acid produced by bacteria to solve the problems of nutrient loss and fruit tree resistance caused by the application of different types of non-organic fertilizers in production. It replaces nitrogen fertilizer, but its treatment is mainly used to prevent apple sugar core digestion during preharvest cultivation, but the postharvest storage time of apples is long, and the effect of this fertilizer is limited during postharvest storage
[0007] The patent literature of the above-mentioned patented candied apples has no relevant description and research on the candied heart rate and related quality during the candied apple storage process. materials, further guaranteeing the quality of candied apples during storage and transportation

Embodiment 1

[0039] A fruit wax material for preventing digestion and transport of sorbitol sugar and its application method. The material is composed of component A and component B. The specific preparation method is as follows:

[0040] Dissolve 45 parts of β-cyclodextrin, 5 parts of citric acid and 50 parts of deionized water at 90°C. During the dissolution process, use high-pressure pulse jet nitrogen blowing and mixing at a frequency of 1200 times / min to obtain component A.

[0041] Component B was obtained by mixing 70 parts of fatty acid triglycerides, 7 parts of ursolic acid, 8 parts of oleanolic acid and 15 parts of α-farnesene under high pressure pulse jet nitrogen blowing.

[0042] Freshly picked Aksu apples were transported back to the laboratory in time, waxed with component A first, and then waxed with component B after natural air drying. Take untreated apples as a control, store them at 20±0.5°C for 30 days, and measure related indicators such as sorbitol and sugar core.

Abstract

The invention relates to a fruit wax material for preventing digestion and transportation of a sorbitol sugar core as well as a preparation method and an application method thereof. The material consists of a component A and a component B, wherein the component A comprises the following components in parts by weight: 1-2 parts of triiodobenzoic acid, 40-62 parts of beta-cyclodextrin, 4-7 parts of citric acid and 43-68 parts of deionized water; the component B is prepared from the following components in parts by weight: 64-82 parts of triglyceride fatty acid, 5-7 parts of ursolic acid, 5-11 parts of oleanolic acid and 10-20 parts of alpha-farnesene. The beta-cyclodextrin is adopted for embedding the triiodobenzoic acid into an apple wax material for the first time, so that TIBA can be slowly released in the storage process after picking, sorbitol is prevented from being transported from the center to the periphery along vascular bundles in the storage process, sorbitol transportation is inhibited, and sugar core digestion is prevented. Experiments prove that the sugar core fruit rate of apples is effectively increased by 33.1%-37.6%, and the sorbitol sugar core index is effectively maintained by 32.9%-36.9%.

Description

technical field [0001] The invention belongs to the field of fruit and vegetable protective agents, in particular to a sorbitol sugar core anti-digestion and transshipment fruit wax material and an application method thereof. Background technique [0002] Reasons for the formation of apple candy hearts: high altitude, relatively cold winter, and few pests and diseases during fruit ripening; sufficient sunshine time, large temperature difference between day and night; mostly sandy soil, less pollutant deposition; mostly glacial snowmelt, cold water for irrigation , clean; the picking period is late, and it is usually picked after it is fully ripe, giving enough time for the sugar to condense into the center of the apple. Sugar apple is not a special variety, and it does not have the imaginary genetic characteristics. It is a physiological disease in the production process of apples, commonly known as water core disease, honey fruit disease, and molasses disease. It mainly occ...
