Lanzhou Ruaner pear ripening method

Abstract

The invention relates to a post-ripening method for Lanzhou Ruaner pears, which is characterized in that: firstly, the post-ripening workshop, cold storage, and fruit baskets are cleaned and sterilized before the fruit is purchased in late September; and then the purchased Lanzhou Ruaner pears are Use a fruit sorting machine to sort the first- and second-class fruits, and pack them according to different varieties and grades, so that the fruits can be packed into 2 / 3 of the fruit baskets, and the relevant information is marked on the labels of the fruit baskets; secondly, according to different varieties, Different grades and different acquisition times are classified and stacked in the post-ripening workshop, and the sterilization lamp is turned on for 5-10 minutes every morning and evening for sterilization; the post-ripening workshop uses a temperature control system to control the temperature at 18-22°C, and uses a mixed-flow fan every morning At 8 o'clock and 8 o'clock in the afternoon, take a breath, one hour each time, and the Ruan'er pears are completely ripe; finally, they are sorted into the cold storage according to the date of purchase, variety, and grade, and they are stacked neatly for frozen storage. The invention has high production efficiency and can realize industrialization.

Description

technical field [0001] The invention relates to the technical field of post-ripening frozen pears, in particular to a post-ripening method for Lanzhou Ruan'er pears. Background technique [0002] Ruaner pear is a climacteric fruit. The biggest feature is that the flesh is hard and sour before harvesting, and the stone cells are many and large. The quality is not good and it is not edible. Ruaner pears are post-ripened after harvesting, the skin turns yellow, the flesh becomes soft, the acidity decreases, the sweetness increases, the juice increases, the fragrance is strong, the food has a unique flavor, and the quality of the fruit is significantly improved. When eating, tear the skin and suck it with your mouth. A pack of fruit juice, like sugar and honey, will melt into your mouth. It is sweet, cool, and very fragrant. The quality of Ruaner pear depends mainly on the sugar content in the fruit, the thickness of the peel, the number of stone cells and the acidity after the...

AI Technical Summary

Problems solved by technology

[0004] The natural post-ripening process of Ruan'er pear is relatively long, during which the fruit undergoes complex physiological changes, which generally results in a decrease in the commercial value of the fruit and a loss of some nutrients, and in the natural post-ripening process, different fruit individuals show obvious asynchrony , it is easy to damage the fruit surface due to extrusion during the post-ripening period of the fruit

In addition, due to global warming in recent years, traditional post-ripening techniques have made it difficult to complete the fermentation and saccharification process of Ruaner pears, let alone freeze and turn black, making it difficult to guarantee quality, which has reduced consumers' recognition of it and lowered sales prices. , the income of fruit growers has dropped significantly
