Embodiment 1

[0015] The 'Huayou' kiwifruit was harvested 144 days after full bloom, and the harvested 'Huayou' kiwifruit was refrigerated at 5°C in the cold storage, and then lowered by 1°C every 24 hours until the storage temperature dropped to 3±0.2°C. Then put it in a refrigerator with a storage temperature of 0.5±0.2°C.

Embodiment 2

[0017] Harvest the 'Huayou' kiwifruit 134 days after full bloom, put the harvested fruit into a cold storage at 5°C, and then lower it by 1°C every 24 hours, until the storage temperature drops to 2±0.2°C, put it directly in a cold storage at 0.5±0.2°C Refrigerate.

Abstract

The invention discloses a golden kiwifruit harvesting and refrigerating technique. The technique comprises the following steps: harvesting the golden kiwifruit 134-148 days after the full-bloom stage; and according to a gradual cooling way, directly refrigerating the harvested golden kiwifruit in a 5-8-DEG C refrigerator, lowering the temperature by 1 DEG C every 24 hours, and refrigerating the golden kiwifruit in a 0.5+ / -0.2-DEG C refrigerator after the refrigerator temperature drops to 2-3 DEG C. The method can effectively relieve the degree of cold damage, prevents the chlorophyll in the fruit from being degraded and hindered, and can implement long-term storage on the golden kiwifruit; after the golden kiwifruit is discharged out of the refrigerator, the flesh can normally turn yellow from green within the shelf life; and thus, the technique maintains the length of the shelf life and the fruit quality, and is beneficial to enhancing the commercial value of the fruit.

Description

technical field [0001] The invention belongs to the technical field of fruit refrigeration, and in particular relates to a harvesting and refrigeration process of yellow-fleshed kiwi fruit. Background technique [0002] Kiwi fruit has unique flavor, rich nutrition, high nutritional value and medicinal value. It is favored by consumers and occupies an important position in the fruit market at home and abroad. In terms of plant classification, kiwifruit is a genus with 66 species. The currently cultivated kiwifruit varieties are distributed in two species of delicious kiwifruit and Chinese kiwifruit. Most of the cultivated varieties have green flesh and hairy skin. The hairless cultivar belongs to the Chinese kiwifruit species, and the variety with yellow flesh is relatively scarce, and its price is several times that of green flesh. Therefore, the color of the flesh has become an important indicator for evaluating the quality of kiwifruit. Some yellow-fleshed varieties have ...
