Food bioactive packaging has received increasing attention from consumers and the food industry for its potential to reduce waste environmental issues. Several materials can be used produce edible films/coats; however, bio-based, cost-effective, sustainable coatings have gained a high reputation these days. For instance, Aloe vera gel (AV) is promising bio-based material films; therefore, present study aimed investigate film-forming abilities of AV Chitosan (CH) combination as active...

Abstract The effects of ultraviolet (UV‐C) and medium heat (70 °C) treatments on the quality fresh‐cut Chokanan mango Josephine pineapple were investigated. Quality attributes included physicochemical properties (pH, titratable acidity, total soluble solids), ascorbic acid content (vitamin C), antioxidant activity, as well microbial inactivation. Consumers’ acceptance was also investigated through sensory evaluation (appearance, texture, aroma taste). Furthermore, shelf‐life study samples...

Piper betle leaf powder is increasingly utilised as a health supplement. In this study, P. leaves were subjected to four different drying methods: convective air-drying, oven-drying, sun-drying, and no drying, with fresh control. Their antioxidant properties then evaluated using colourimetric assays GC-MS. Results showed that the sun-dried had highest (p < 0.05) total capacity (66.23 ± 0.10 mg AAE/g), polyphenol content (133.93 3.76 GAE/g), flavonoid (81.25 3.26 CE/g) DPPH radical...

Postharvest treatments of fruits using techniques such as ultraviolet-C have been linked with maintenance the fruit quality well shelf-life extension. However, effects this treatment on a proteomic level remain unclear. This study was conducted in order to understand response mango postharvest UV-C irradiation.Approximately 380 reproducible spots were detected following two-dimensional gel electrophoresis. Through analysis, 24 observed be differentially expressed treated and 20 successfully...

Drying kinetics of Malaysian Moringa oleifera leaves was investigated using a convective-air dryer. The drying parameters were: temperature (40, 50, 60, 70 °C), air velocity (1.3 m s–1, 1.7 s–1). process took place in the falling rate period and there an absence constant this experiment. Six mathematical models (Lewis, Henderson Pabis, Wang Singh, Peleg, Page, logarithmic) were selected for description characteristics leaves. Singh model determined as best based on highest overall...
