摘要
非浓缩复原汁(not from concentrate,NFC)果汁产品品质对原料的要求较高。为评价不同品种苹果加工NFC果汁的适应性,以10个苹果品种为原料,对其固酸比、色值、总酚、维生素C、稳定性等12个指标进行测定,并以测定结果为依据,采用层次分析法构建模型。结果表明,NFC苹果汁品质评价模型为Y=0.0866×可溶性固形物+0.1841×固酸比+0.2385×总酚+0.0408×L*-0.4500×稳定性,依据此模型计算得出‘富士’苹果的得分最高,这说明‘富士’苹果较适宜加工NFC果汁。采用模糊评价法对构建的模型进行验证,建模得分与模糊评价法得分呈线性相关,因此该模型可用于不同品种苹果加工NFC果汁适应性的判定。
The quality of NFC fruit juice requires high raw materials.In order to evaluate the adaptability of different varieties of apples for processing NFC apple juice,10 varieties of apples were used as raw materials,12 indicators such as sugar-acid ratio,color value,polyphenols,vitamin C and stability were measured,and then the analytic hierarchy process was used to build the model.Results showed that the quality characteristic model of NFC apple juice was Y=0.086 6 × soluble solids + 0.184 1 × sugar-acid ratio + 0.238 5 × polyphenols + 0.040 8 × L* -0.450 0 × stability. According to this model, the ‘Fuji’ apple scored the highest, indicating ‘Fuji’ apple was more suitable for processing NFC juice. The fuzzy evaluation method was used to verify the constructed model, and the score obtained by the modeling was linearly related to the score of the fuzzy evaluation method. Therefore, this model could judge the adaptability of NFC apple juice for apple processing.
