Problems solved by technology

But Saiwaihong apple is a typical small fruit, with an average single fruit weight of about 60g, short growth and development period, high temperature season when it matures, and thin skin, not resistant to bumping, not resistant to storage and transportation, stored under natural temperature conditions after harvest for 6~ It will become soft in 8 days. Studies have found that Saiwaihong has a good effect on low temperature and CO 2 Extremely sensitive, once the storage temperature, humidity, and gas components are improperly configured under low temperature conditions, quality deterioration problems such as peel cracking, dehydration and softening of the pulp, browning of the tissue, and decline in flavor will occur, causing serious damage to the fruit grower or storer. loss
At present, most of the Shangsai Waihong apples are refrigerated using the technology and method of storing Fuji and other big apples. Although they can be stored for 60-90 days, the shelf life is only 2-3 days. Even browning, fruit rot, and low commercial fruit rate, this characteristic of not being able to withstand storage and transportation restricts the healthy development of the excellent characteristic apple industry of Saiwaihong

Abstract

The invention relates to the technical field of apple storage and preservation, in particular to a method for improving storage quality and extending shelf life of apple fruit. The method comprises the following steps: S1, pre-harvest treatment; S2, preparation before storage; S3, harvesting; S4, transportation; S5, fumigation; S6, salicylic acid treatment; S7, packaging; S8, storage by two-stagecooling method; and S9, modified atmosphere storage. The method adopts a combination of physical and chemical methods, the apples are sprayed with benomyl and thiophanate methyl wettable powder at 30to 15 days before the suitable harvesting period of the apples, subjected to 1-methylcyclopropene and salicylic acid treatment after harvesting, packaged with a fresh-keeping bag with single fruit andnon-woven fabrics, stored by a cooling method at two periods at an early stage, and then subjected to modified atmosphere storage.

Description

technical field [0001] The invention relates to the technical field of apple storage and preservation, in particular to a method for improving the storage quality of apple fruit and prolonging the shelf life. Background technique [0002] "Saiwaihong", also known as "Splendid Begonia" and "Chixinguo", passed the Inner Mongolia Autonomous Region forest tree variety certification in December 2012 (the variety number R-SC-MP-002-2012) and was named. The fruit of this variety is broadly conical, like a chicken heart, with a light yellow skin. When it is nearly ripe, the whole fruit surface is bright red, and when it is ripe, the color turns dark red. Fragrance, the soluble solid content of the fruit is as high as 16.5% to 21.5%, the total soluble sugar content is 13.6% to 16.5%, the titratable acid content is 0.735% to 0.900%, and the vitamin C content is as high as 140.0 to 180.5mg / kg. The quality is better than The high-quality large apple "Hanfuhe Hongfuji" is a Chinese char...
