Qualitative Performance and Consumer Acceptability of Starch Films for the Blueberry Modified Atmosphere Packaging Storage

Abstract

The sustainability of packaging is an important part of food system innovation and it can infl uence the purchase decision for the fresh produce. In this work, we evaluated the qualitative performance and the consumer acceptability of three starch fi lms for the blueberry modifi ed atmosphere packaging (MAP) storage under fl uctuating temperatures. Fruits cv. Duke were monitored for up to 18 days (15 days at 1±1°C and 3 days at 20±1°C). The respiration rate of the blueberries and the permeability of the fi lms affect the initial atmospheric composition (0.2 kPa CO 2 and 21.2 kPa O 2 ) inside each package infl uencing the headspace gas composition and the quality parameters of the fruits. The F3 fi lm has better controlled O 2 values inside the packages up until the end of storage (5.7 kPa) and it maintained the highest anthocyanin content (156.21 mg C 3 G/100 g FW) and antioxidant capacity (22.18 Fe 2+ /kg) of fruits at 20±1°C.

Shelf life prolongation of cherry tomato using magnesium hydroxide reinforced bio‐nanocomposite and conventional plastic films

“…Lycopene synthesis is maximum in the temperature range of 12 to 32 °C. Temperatures below 12 °C inhibit the biosynthesis and above 32 °C obstruct the process (Giuggioli et al, ; Souza et al, ). The controlled conditions of temperature and humidity along with a packaging intervention delayed the ripening of fruits.…”

“…Cherry tomatoes are rich sources of lycopene, ascorbic acid, carotenoids, and phenols. During maturation, they go through numerous complex biochemical and physiological changes including variation in flavor, texture, and color thereby making them captivating and flavorsome (Giuggioli, Girgenti, & Peano, ; Souza et al, ). In climacteric fruits, like cherry tomato, the ripening occurs in conjugation with respiration (Gharezi, Joshi, & Sadeghian, ).…”

Monitoring of oxygen using colorimetric indicator based on graphene/TiO2 composite with first‐order kinetics of methylene blue for modified atmosphere packaging

“…Modified atmosphere packaging (MAP), as an established food packaging and preservation technique, can prolong the shelf life, enhance food value, and protect the quality of food against physical, chemical, biological, and other aspects of deterioration . Modified atmosphere packaging for various foodstuffs is flushed with different ratios of nitrogen, carbon dioxide, and oxygen, and the concentration of oxygen is controlled under the ideal level to guarantee the safety and quality of foods .…”
