| Abstract:[Objective] Yuping yellow peach is Prunus persica "Jinxiu yellow peach" .Yuping County , Guizhou province have the unique climate and environmental, and these have contributed to excellent quality of Yuping yellow peach.This study aim to find out the quality of Yuping yellow peach and establish a comprehensive fruit quality evaluation method,and then give a provide reference for the efficiency planting,agricultural product processing and utilization of yellow peach. [Methods] Ten samples of yellow peach from different orchards in Yuping County were collected, and sensory evaluation was conducted from four aspects: flavor, aroma, texture and appearance. Appearance indexes such as single fruit weight, hardness and color, physical and chemical and nutritional quality indexes such as moisture content, total acid content, soluble sugar and mineral elements were determined. The quality was evaluated by using coefficient of variation, SPSS correlation analysis and membership function value.[Results] Among the 10 samples of Yuping yellow peach, there were significant differences in the quality of each peach. The soluble solid average content was 12.3%, the total acid average content was 2.72 g/kg, and the solid acid ratio was 46.15. Based on sensory evaluation, all the sample had soft with firm taste, sweet with sour, rich aroma .The fruit pit was small , which made the edible rate was above 96%. It was rich in soluble sugar, glucose, amino acids, protein, mineral elements. The average content of calcium was59.22 mg/kg, the average content of potassium was 1748.27 mg/kg, the average content of magnesium was 54.12 mg/kg. [Conclusion] The sensory indexes and nutritional indexes of Yuping yellow peach were investigated.The quality of Yuping yellow peach was comprehensively evaluated by membership function method. No. 02 yellow peach had outstanding performance in sensory evaluation, and No. 08 yellow peach had the best membership function value in evaluating fruit quality.which provided data support for efficient cultivation, storage and processing of Yuping yellow peach. |
