Outline
To optimize the processing of Chaenomeles speciosa leaf beverage using fuzzy sensory evaluation and response surface methodology, and investigate its shelf life and antioxidant activity.
Using sensory scores as the key indicator, the formulation was optimized by fuzzy mathematics sensory evaluation combined with single-factor analysis and response surface methodology. The flavor profile was characterized by headspace solid-phase microextraction coupled with gas chromatography-mass spectrometry, electronic nose, and electronic tongue bionic systems. Furthermore, the beverage’s shelf life was predicted based on a chemical reaction kinetics model incorporating the Arrhenius equation.
The optimal formulation of beverage was 60 mL extract solution, 2 g sweetener and 0.01 g DL-malic acid, achieving a sensory score of 88 points. The beverage exhibited a rich flavor, bright color and a taste profile of initial sweetness followed by bitterness. A total of 19 kinds of volatile aroma compounds were identified, predominantly aromatic compounds. The product exhibited good stability, with a shelf life of 189, 146 and 128 days at 4, 25 and 37 °C. respectively, the antioxidant capacity remained stable during the storage period.
The beverage has good flavor and antioxidant activity, this study provides an effective solution for the value-added utilization of by-products in the Chaenomeles speciosa industry, contributing to the enhancement of the industry’s overall value.
