Abstract

The invention provides a method for prolonging the freshness lifetime of harvested citrus reiculata blanco and relates to the technical field of freshness keeping of fruits and vegetables. The methodfor prolonging the freshness lifetime of the harvested citrus reiculata blanco, provided by the invention, comprises the following steps: (1) pre-treating the citrus reiculata blanco; (2) carrying outheat shock treatment; (3) storing; (4) pre-cooling; and (5) storing at a low temperature. According to the method for prolonging the freshness lifetime of the harvested citrus reiculata blanco, the freshness lifetime of the citrus reiculata blanco can be prolonged and the mouthfeel, sweetness, and color and luster of the citrus reiculata blanco are not influenced; the freshness keeping of the citrus reiculata blanco is realized and the disease resisting capability of the citrus reiculata blanco is greatly enhanced; the yield is improved and the rotting speed is delayed.

Description

【Technical field】 [0001] The invention relates to the technical field of fruit and vegetable fresh-keeping technology, in particular to a method for extending the fresh-keeping period of post-harvest tangerines. 【Background technique】 [0002] Wo Tangerine is a hybrid of "Temple" Tangerine and "Dancy" Red Tangerine. This variety is a late-maturing hybrid citrus variety. Also has high nutritional value, it contains 13.3% soluble solids, 0.58% titratable acid, 12.76 g / 100 ml invert sugar, 6.84 g / 100 ml reducing sugar, 23.69 mg / 100 ml Vc content, 22.9 solid-acid ratio , the edible rate is 74.62%, and the juice yield is 59.56%. After the fresh citrus is harvested, it is still undergoing complex physiological changes, biological changes and physical changes in the process of being shipped to all parts of the world. It is very important to keep the citrus fresh and not rot. [0003] With the improvement of people's living standards, people's demand for off-season fruits and veg...
