Abstract

Abstract:

【Objective】 In this paper, the effects of different pH values coupled with ultrasound irradiation on the color, texture and some physicochemical properties of the apricot kernels during debitterizing were investigated. Correlation analysis of all measured variables was conducted to simplify the evaluating indicators of the quality of debitterizing apricot kernels with different solvents. In addition, multivariate data analysis was applied to categorize the debitterizing solvents and provide the theoretical base for the selection of debitterizing solvents in the debitterizing processing of apricot kernels. 【Method】 Determinations of the amygdalin, water content and beta-glucosidase activity of the apricot kernels, and the contents of total phenols, proteins, reducing sugars and soluble solids in the debitterizing solutions were conducted by the high performance liquid chromatography, spectrophotometer and abbe refractometer, etc, respectively. In addition, the texture and organoleptic properties of the debitterized apricot kernels were also investigated by the texture analyzer and sensory evaluation test, respectively. Finally, principal component analysis (PCA) and cluster analysis (CA) were applied to classify the six kinds of debitterizing solvents. 【Result】 Compared with the untreated sample, the color, hardness, fracturability, chewiness, resilience, gumminess and sensory evaluation of the debitterized apricot kernels were significantly different after being debitterized by the six kinds of debitterizing solvents. In the meantime, the moisture content and the activity of beta-glucosidase of the apricot kernels increased significantly. Based on the comprehensive analysis of the physicochemical indicators, the debitterizing time was the shortest (only 90 min), and the loss of the nutrients in the apricot kernels was less than the other treated samples, when the pH of the debitterizing solution was at the value of 5. Correlation analysis showed a certain correlation among the indicators. The results of PCA and CA provided the same classification, and the six kinds of debitterizing solvents could be classified into three categories. Moreover, the effects of the different solutions on the apricot kernels in the same category were not significant. 【Conclusion】 The citric acid solution with a pH of 5 could be used as the optimal solution to remove the bitterness of apricot kernels, which not only accelerated the bitterness of apricot kernels, but also reduced the loss of nutrients of apricot kernels. All these results could provide the support for the industrial rapid debitterizing of apricot kernels.

Key words: apricot kernel, debitterizing solvents, texture, sensory evaluation, principal component analysis, cluster analysis
