Determination and evaluation method for quality of lychees suitable for can processing

Abstract

The invention discloses a determination and evaluation method for the quality of lychees suitable for can processing. According to the method, the total acidity, brittleness and chromatic aberration a0 value of a to-be-detected lychee are only required to be determined; the determined values are substituted into the formula that Y is equal to a sum of a difference obtained by subtracting a product of 8.319 and the total acidity and a product of 0.445 and a0 value from (-2.471) and a product of 0.080 and the brittleness; if Y is larger than or equal to minus 1.55, the to-be-detected lychee is suitable for being processed into a can; and if Y is larger than minus 4.29 and smaller than minus 1.55, the to-be-detected lychee is basically suitable for being processed into the can; and if Y is smaller than or equal to minus 4.29, the to-be-detected lychee is not suitable for being processed into the can. According to the method, lychee can processing is studied with a scientific method, an evaluation method is established, determination of special lychee varieties suitable for can processing is facilitated, healthy and fast development of processing industry for agricultural products is promoted, and important basis can be also provided for lychee breeding, raw material base establishment and adjustment of a plant structure for farmers.

Description

technical field [0001] The invention relates to a method for measuring and evaluating the quality of fruit suitable for canning, in particular to a method for measuring and evaluating the quality of canned lychees. Background technique [0002] Lychee belongs to evergreen trees, native to southern China, is a tropical and subtropical characteristic fruit, delicious taste, rich nutrition, remarkable health care function. In my country, the research on litchi mainly focuses on the breeding of improved varieties, cultivation management, damage by diseases and insect pests, and storage and preservation. There are few reports on its composition and deep processing. At present, the processed products of lychees are still mainly dried lychees. Not only is the product single, but also the process is simple, the technology content is low, the market price is not high, and the added value is low. Canned fruit is an emerging main category of canned food exported from China, and it wil...
