Essential oil vapours suppress the development of anthracnose and enhance defence related and antioxidant enzyme activities in avocado fruit

TL;DR: Postharvest thyme oil treatment has positive effects on reducing anthracnose in avocados, and the activities of defence enzymes including chitinase, 1, 3-β-glucanase, phenylalanine ammonia-lyase and peroxidase were enhanced and the level of total phenolics in thymeOil treated fruit was higher than that in untreated (control) fruit.
Journal ArticleDOI

Influence of photo-selective netting on fruit quality parameters and bioactive compounds in selected tomato cultivars

TL;DR: In this paper, three types of photo-selective nets (red, yellow and pearl with 40% shading) were compared with commercial black net for fruit quality parameters [firmness, soluble solids concentration, titratable acidity, fruit mass, CIE-Lab colour parameters (L*, a*, b*] bioactive compounds (ascorbic acid, lycopene, -carotene, total phenols) and total antioxidant activity in three tomato cultivars (AlfaV, Irit and SCX 248) at harvest.
Journal ArticleDOI

Thyme oil vapour and modified atmosphere packaging reduce anthracnose incidence and maintain fruit quality in avocado.

TL;DR: MAP + TO combination treatment reduced the incidence and severity of anthracnose, grey pulp, vascular browning, weight loss and loss of fruit firmness, and showed acceptable taste, flavour, texture and higher overall acceptance.
Journal ArticleDOI

Phytochemicals and Overall Quality of Leafy Lettuce (Lactuca sativa L.) Varieties Grown in Closed Hydroponic System

TL;DR: Red lettuce varieties are rich in bioactive compounds and antioxidant property mainly due to higher total phenols and flavonoid compounds and other red lettuce varieties can be recommended for mixed lettuce salads or as whole product.
Journal ArticleDOI

Antifungal Activity and Chemical Composition of Thyme, Peppermint and Citronella Oils in Vapor Phase against Avocado and Peach Postharvest Pathogens

TL;DR: The results of this study provide a novel practical tool using thyme oil vapors to reduce losses because of postharvest diseases in avocado, and thus ensuring safe food.
