[0004] The purpose of the present invention is to provide a method for measuring the quality of peanuts used in peanut sprouts and its evaluation method. This method can be used to predict whether a certain peanut variety is suitable for the production of peanut sprouts, so as to overcome the current peanut sprout processing industry that uses varieties to produce peanuts. Resource waste and economic loss caused by sprouts

Embodiment l
[0026] A method for measuring the quality of peanuts for peanut sprouts and an evaluation method thereof, comprising the steps of:
[0028] Table 1 Quality analysis of tested peanut varieties
[0029]
[0030] The numerical value in the above-mentioned table 1 is substituted into the quality comprehensive score Y general evaluation of peanuts for peanut sprouts:
[0031] Y overall evaluation=2. 3160709-0.00898×100 kernel weight+0.01935×crude protein content-0.01062×nut diameter+0.01285×water content+0.04051×polysaccharide content+0.0906×crude fat content+0.02156×three-day weight gain rate+0.02708×crude fiber content
[0032] Obtain the total evaluation value of the peanut sprout quality Y of the variety to be tested, as shown...
Embodiment 2
[0037] Example 2: Establishment of a peanut quality evaluation model suitable for peanut sprouts
[0038] l. Determination of peanut quality
[0039] Take 20 peanut samples harvested in 2015 (in line with the normal distribution of peanut populations), including Baisha 1016, Haihua, Weihua No. 8, Fenghua No. 1, Shanhua No. 9, Huayu 22, Yuhua 9414, Fuhua 12 , Huayu 23, Huayu 19, Huayu 25, Fuhua 19, Huayu 51, Osmanthus 17, Kai 1517, Huayu 53, White Peanut, Colorful Peanut, Fuhua 16, Fuhua 13 and Yueyou 256. There are 10 indicators of sensory quality, physicochemical nutritional quality and processing quality of the varieties; the variation range, mean, standard deviation and coefficient of variation of the basic data of the selected 15 peanut varieties are analyzed, and the results are shown in Table 1;

Abstract
The invention relates to a quality determination method of peanuts for peanut sprouts and an evaluation method thereof. The method comprises the following steps: measuring nuts weight, nut diameter, water content, crude protein content, polysaccharide content, crude fat content, three-day weight gain rate and crude fiber content of peanuts to be determined; introducing above measured values into a formula to obtain quality comprehensive score Y overall rating of the peanuts for peanut sprouts. According to the formula, the Y overall rating= 2.3160709-0.00898 * nuts weight + 0.01935 * crude protein content- 0.01062 * nut diameter + 0.01285 * water content + 0.04051 * polysaccharide content + 0.0906 * crude fat content + 0.02156 * three-day weight gain rate + 0.02708 * crude fiber content. By the quality determination method and the evaluation method, whether a peanut variety is suitable for production of peanut sprouts can be predicted. The analytical method is simple and has degree of standardization. It is confirmed through model validation that whether the peanut variety is suitable for production of peanut sprouts is reflected objectively and accurately. The method is simple and feasible in production practice.
Description
technical field [0001] The invention relates to a quality determination method and an evaluation method of peanuts for peanut sprouts, belonging to the fields of nutrition and food processing. Background technique [0002] As an oil crop, peanut is the main economic crop in my country. Due to its rich nutritional value, peanut processing products have been paid more and more attention by people. In recent years, a new sprout vegetable has appeared on the market - peanut sprout has become a hot topic of discussion. Peanut sprouts can be cultivated without soil under artificial control, without fertilization, occupying a small area, and can also be cultivated three-dimensionally. It is a kind of pollution-free and pollution-free green food. Because it is rich in nutrients and dietary fiber, it has the effect of nutrition and health care, and is loved by the majority of consumers. Because the germination of peanuts can hydrolyze the protein in the cotyledons into amino acids...
