Abstract

In order to investgate the effects of H2S on the quality of cold-storage passion fruit, fresh harvested fruits were treated with different concentrations of H2S(0 mmol/L, 1 mmol/L, 2 mmol/L, 3 mmol/L), packaged with BOPP plastic wrap and placed into 5±1°C for 35 days. Samples were randomly selected and at 7-days interval during cold storage, compared the preservation effect of different concentrations of H2S. The results indicated that the fruits with 2 mmol/LH2S treatment have better chroma and lower weight loss rate, and soluble solid content, titratable acidity, vitamin C, sugar were preserved at higher level than that of control fruits during storage time. These results showed that 2 mmol/LH2S treatment could maintain the quality of passion fruit during cold storage.

Highlights

Passion fruit (Passiflora etuis Sims) is grassy vine of the passifloraceae, the scientific name is passiflora, known as egg fruit or Brazil fruit
Passion fruit is a kind of tropical fruit origined from Brazil, it has strong respiration and fast ethylene response while at a high temperature in the mature season, seriously water lose during storage, prone to shriveling, peel color darkening, rot, fermentation to bad odor, etc[3,4]
The results revealed that application of 2 mmol/L H2S maintained the best quality of passion fruit during cold storage

Summary

Introduction

Passion fruit (Passiflora etuis Sims) is grassy vine of the passifloraceae, the scientific name is passiflora, known as egg fruit or Brazil fruit. Passion fruit is a kind of tropical fruit origined from Brazil, it has strong respiration and fast ethylene response while at a high temperature in the mature season, seriously water lose during storage, prone to shriveling, peel color darkening, rot, fermentation to bad odor, etc[3,4]. It is all-important to study the preservation of post-harvested passion fruit to maintain its commodity and prolong its shelf life. In this study, ‘Ziguo NO1’was used as the materials to explore the influence of H2S treatment with different concentrations on the physiological and quality change of cold-storage passion fruit, so as to provide production guidance for the preservation of passion fruit
