Abstract

The invention discloses a green peeling method for kiwi fruit. The method comprises the following steps: S1) performing intermittent vacuum treatment on kiwi fruit till kiwi fruit surface slightly swells; S2) soaking the kiwi fruit after intermittent vacuum treatment into a waxy degradation solution, and performing ultrasonic immersion treatment; S3) rubbing and peeling the kiwi fruit treated in step S2). According to the green peeling method provided by the invention, shape and quality of fruit pulp can be extremely prevented from being damaged; water consumption and discharge capacity are low; peeling effect is excellent; treating condition is mild; the method is beneficial to guaranteeing pulp quality and complete fruit shape, is capable of increasing pulp yield and is capable of extremely reducing pollutant discharge and resource waste.

Description

technical field [0001] The invention relates to the field of agricultural product processing, in particular to a green peeling method for kiwifruit. Background technique [0002] Kiwifruit (Actinidia Chinensis Planch), also known as kiwi fruit, commonly known as carambola, hair peach, and kiwi fruit, is a fruit native to China. There are more than 52 species of Actinidia in China, many of which are edible.
