Influence of acidic electrolyzed water combined with vacuum precooling treatment on quality and antioxidant performance of fresh Lycium barbarum L.

In this work, to evaluate the role of acidic electrolyzed water (AEW) combined with vacuum precooling (VP) treatment in fresh goji preservation, the physicochemical properties and anti-oxidation indexes of goji berries were compared between the AEW+VP-treated and control (VP treatment) groups during storage at 4, 7, and 10 degrees C. The results showed that AEW+VP could effectively inhibit the decrease in L* and a* values, reduce the respiratory rate, delay the loss of vitamin C content, and maintain higher total soluble solid (TSS) content. Compared to the control, AEW+VP-treated goji maintained higher catalase (CAT), peroxidase (POD), and superoxide dismutase (SOD) activity. Therefore, AEW+VP treatment could effectively improve the storage quality and extend the shelf life of fresh goji berries. Practical applications Acidic electrolyzed water, a clean and environmentally friendly preservation technology, combined with vacuum precooling extended the shelf life of fresh goji berries while delaying the aging of goji berries at different storage temperatures. In this sense, AEW+VP had certain stability in enhancing the storage quality and extending the shelf life of goji berries, which can be regarded as an effective strategy for promoting the preservation of agricultural products.
