Abstract

Introduction: Replacement of synthetic pesticides and antifungal compounds with natural ones for reducing the decay of agricultural products is a challenge in the industry. Materials and Methods: In order to investigate the effects of sodium alginate (Alg-Na) and pomegranate peel extract (PPE) on reduction of decay and improving the postharvest quality of sweet lemon fruit, an experiment based on Completely Randomized Design (CRD) with six treatments and three replications was conducted. Treatments included Control (C), Sodium Alginate (Alg-Na 1%), PPE, PPE/Water ratio of 1: 1, PPE/Water ratio of 1: 2, PPE/Water ratio of 2: 1 combined with Alg-Na 1%. Treated fruits were kept for 35 days at 20 oC and the fruit characteristics were evaluated at seven day intervals. Traits such as Weight loss%, fruit firmness (N), total acidity (TA %), pH, TSS%, vitamin C, fruit skin color (a*, b* and L*) and organoleptic properties were measured. Results: The results showed that postharvest application of PPE and Alg-Na 1% had significant effect on maintenance of sweet lemon in storage as compared to untreated fruits. The lowest fruit decay and microbial concentration was obtained in fruit treated with PPE and Alg-Na 1% as compared to other treatments. The lowest Weight loss% was obtained in fruit treated with PPE and Alg-Na 1% and the highest was observed in untreated fruits. Fruit treated with PPE and Alg-Na 1% showed the highest fruit firmness at the end of storage period as compared to the control. The highest Vitamin C at the end of storage was observed in fruit treated with PPE and Alg-Na 1%. The sensory test showed that consumer's acceptability was increased by increasing the PPE concentration plus at Alg-Na 1%. Conclusion: Our study suggests that the use of PPE combined alginate coating has the potential to maintain sweet lemon quality and extend its postharvest life to 35 days.
