Isolation, Identification and Methods for Inhibiting Growth of the Spoilage Molds from Postharvest Strawberry Fruits

Abstract

Abstract: Objective: The molds from spoilage strawberries were isolated and identified, and the methods for preventing rot were explored to provide a reasonable and effective basis for controlling the molds purposively during the processes of keeping fresh, storage and deep processing for strawberries. Methods: The molds isolated from strawberry fruits were identified by morphological characteristics and DNA sequence analysis. Results: The molds causing strawberry rot included Penicillium commune, Penicillium chrysogenum, Penicillium olsonii, Penicillium spinulosum, Aspergillus terreus, Aspergillus fumigates, Trichoderma atroviride, Glomerella acutata and Pestalotiopsis sp.. Furthermore, the molds from strawberry fruits were inhibited respectively using ultraviolet, sorbic acid, phytic acid sterilization combining cold storage. It was showed that cold storage after 0.05% sorbic acid was the best preservative method for strawberry fruits. Conclusion: The molds causing strawberry rot were classified 5 genera and 9 species, among which Penicillium was the dominant genus causing strawberry rot. The present results showed that 0.05% sorbic acid solution was an ideal method for fresh keeping and storage of strawberries
