| 1 | Evaluation Model Construction of Peak Sweet Processing Suitability of Different Varieties of Chestnut显示文摘[Objective]The aims was to construct peak sweet processing suitability evaluation model and determine the suitable varieties of peak sweet processing in chestnut.[Method]'Zaofeng','Yan Long'etc.15 chestnut varieties in Yan Shan area were taken as research objects and investigated the sensory,physicochemical nutrition and processing indexes.The correlation analysis,principal component analysis and cluster analysis were adopted to simplify and calculate the evaluation index,and set up the mathematical model.[Result]Obvious differences in different varieties of raw materials and products of each index and some indicators existed significant correlation relationship;principal component analysis determined the five principal components:hardness,b value,moisture content,total sugar,browning degree and edible rate or the core indicators of quality evaluation in peak sweet chestnut,and the establishment of products comprehensive value scoring model:Y=0.033 509 hardness+0.033 509b value+0.185 173 moisture content+0.208 983 total sugar+0.108 499 browning degree+0.430 327 ratio of feed,peak sweet chestnut quality and raw material associated model:Y=-1.109+0.015 ratio of good fruit-0.018 kernel hardness+0.008 starch.[Conclusion]Peak sweet chestnut processing suitability evaluation model can provide the basis for chestnut processing and the suitable processing of the chestnut breeding;'Yanguang','Yan Long','Yankui',are very suitable,and'Zibo','Yan Ping'are more appropriate for peak sweet processing. | Haoning GUO Yuhua ZHAO Xuedong CHANG Bingfeng YANG Zanyi WU | 2016 | Agricultural Science & Technology2016，17，9： | 0 |
