Study on the effect of drying and storage conditions on the shelf-life quality of pecan products

Abstract

Abstract:

The aim of this study was to investigate the effects of post-harvest drying methods and cold storage conditions on the quality of pecan products during shelf life. By comparing changes in acid value，peroxide value，and sensory quality scores of pecans under different conditions，the optimal drying and storage conditions were identified：sun-drying was employed to reduce the moisture content of the raw material to 5%，with a cold storage temperature of 3 °C，and a relative humidity of 50%. The determination of these processing parameters provides a scientific basis for the drying and storage of pecan. It contributes to improving the quality of the product while effectively prolonging its shelf life，thereby better meeting market demands.

Key words: pecan, drying method, storage condition, shelf life, quality
