摘要
The effect of cold atmospheric plasma (CAP) and pulsed electromagnetic fields (PEMF) on the metabolic process, microbiological, enzymatic and quality parameters of fresh strawberries, after processing and during storage at 1 and 6 degrees C, was studied. CAP was more effective on microorganisms, reducing the total viable count by similar to 0.9 logCFU/g. Phenolic compounds and antioxidant activity were increased after CAP processing by similar to 20.9 and 16.5%, respectively. PEMF strawberries were firmless by similar to 16% compared to control. Both treatments did not significantly affect the weight loss, color, anthocyanins content and pH-value. B-glucosidase activity was higher for PEMF strawberries by at least 35 and 20%, compared to control and CAP respectively, explaining PEMF enhancing aromatic-profile. Ascorbic acid was decreased during storage, nevertheless, nonthermal treated samples showed higher values by at least 10%, compared to control samples. The shelf-life at 1 degrees C for control, CAP and PEMF strawberries was estimated as 13, 17 and 15 days, respectively.
