Abstract

OBJECTIVE

To evaluate the 8 main quality characteristic indexes of fruit-using Chaenomeles speciosa and C. sinensis fruits produced in Chongqing and explore the comprehensive assessment for the fresh eating-quality of the samples based on the theory of fuzzy comprehensive.

METHOD

The total sugar content, titratable acid content, ascorbic acid content and superoxide dismutase (SOD) activity of fresh samples were determined, and the oleanolic acid, ursolic acid, total flavones and total saponins content of dried sample were determined by HPLC and colorimetry method. The fuzzy probability method was used to comprehensively evaluate their fresh eating-quality of the fruit-using C. speciosa and C. sinensis fruits produced in Chongqing.

RESULT

The mean SOD activity of C. speciosa and C. sinensis fresh fruits separately was 15.99 U x mg(-1) and 27.40 U x mg(-1), respectively. And the fresh fruit titratable acid content, total sugar content, ascorbic acid content separately was 0.357 g x L(-1), 0.854 mg x L(-1), 1.118 mg x L(-1) and 0.252 g x L(-1), 0.845 mg x L(-1), 1.260 mg x L(-1), respectively. The oleanolic acid, ursolic acid, total flavones and total saponins content was 0.320%, 0.461%, 43.90 mg x g(-1), 23.11 mg x g(-1) and 0.255%, 0.176%, 41.24 mg x g(-1), 15.01 mg x g(-1), respectively. The Chaenomeles speciosa and C. sinensis sample quality mean comprehensive evaluation value was 0.599 and 0.367 based on the fuzzy probability method.

CONCLUSION

The edible quality of fruit-using C. speciosa fruits are better than C. sinensis fruits produced in Chongqing. And the fuzzy probability method could be used to quality comprehensive evaluation of samples containing many trait paramaters.

摘要

目的

评价重庆产食用型木瓜和中华猕猴桃果实的8项主要品质特征指标，并基于模糊综合理论探索对样品鲜食质量的综合评价。

方法

测定新鲜样品的总糖含量、可滴定酸含量、抗坏血酸含量和超氧化物歧化酶（SOD）活性，采用高效液相色谱法和比色法测定干燥样品的齐墩果酸、熊果酸、总黄酮和总皂苷含量。运用模糊概率法综合评价重庆产食用型木瓜和中华猕猴桃果实的鲜食质量。

结果

木瓜和中华猕猴桃新鲜果实的SOD活性均值分别为15.99 U·mg⁻¹和27.40 U·mg⁻¹。新鲜果实的可滴定酸含量、总糖含量、抗坏血酸含量分别为0.357 g·L⁻¹、0.854 mg·L⁻¹、1.118 mg·L⁻¹和0.252 g·L⁻¹、0.845 mg·L⁻¹、 1.260 mg·L⁻¹。齐墩果酸、熊果酸、总黄酮和总皂苷含量分别为0.320%、0.461%、43.90 mg·g⁻¹、23.11 mg·g⁻¹和0.255%、0.176%、41.24 mg·g⁻¹、15.01 mg·g⁻¹。基于模糊概率法，木瓜和中华猕猴桃样品质量综合评价均值分别为0.599和0.367。
