Evaluation Methods and Indices of the Suitability of Different Peanut Varieties for Boiling
Currently,boiled peanut varieties are disordered in the field,the evaluation standard is vague,and the qual-ity of boiled peanuts of different varieties varies dramatically.Evaluation of the suitability of different peanut varieties for boiled peanut processing is urgently necessary,and the corresponding evaluation methods and indicators should be estab-lished to provide a reference basis for the evaluation of the suitability of boiled peanut processing and to assist the high-quality development of the boiled peanut industry.In this study,23 fresh-edible peanuts were fully evaluated for their basic nutrient composition,and quality indicators of boiled peanuts.Hierarchical cluster analysis,correlation analysis and logistic regression model were used to establish the evaluation methods and indices for the suitability of boiled peanut processing,and to screen out the special varieties suitable for boiled processing.The first-grade standard of boiled peanut quality was determined:Boiled peanut pod length 29.13-36.37 mm,pod width 15.38-15.87 mm,hardness 3 137.35-3 363.29 g,protein content 23.01-24.14 g/100 g,sucrose content 3.55-5.19 g/100 g.Five significantly related variables were screened and determined:The contents of fat,protein,sucrose,crude fibre,and arginine at P＜0.05.The suit-ability evaluation model of boiled peanut was established using logistic regression,and the accuracy of internal validation was 91.30％ .The suitability evaluation methods and indices of boiled peanut processing were established,and six special varieties(1,7,8,9,10,19)were screened to be suitable for processing boiled peanut.
