Cassava starch films incorporated with clove essential oil and nanoclay as a strategy to increase the shelf life of strawberries

Abstract

The incorporation of essential oil and nanocomposites can develop bioplastics with antioxidant and antimicrobial effects that extend the shelf life of food. In this study, active cassava starch films were incorporated with clove essential oil (CEO) and montmorillonite (MMT) for application on fresh strawberries. Central composite design was used in the development of cassava starch active films and the mechanical, barrier, antioxidant and antimicrobial properties were evaluated. The effects of active films on the quality of fresh strawberries were investigated. The incorporation of MMT and CEO promoted better mechanical performance (elongation greater than 180%), greater light barrier properties (opacity greater than 17%) and high antioxidant action due to the content of polyphenols present (32 mg GAE/g). Strawberries packed with the active films showed less changes in the parameters of colour, acidity and microbial contamination during the storage period evaluated.

Recent trends in the application of films and coatings based on starch, cellulose, chitin, chitosan, xanthan, gellan, pullulan, Arabic gum, alginate, pectin, and carrageenan in food packaging

“…Reinforcing compounds can also be used to improve the characteristics of starch packaging. The starch packing added other compounds like CS (Fonseca‐García et al., 2021), cellulose (Zhang et al., 2023), oils (Gao et al., 2020), proteins (Wu et al., 2023), nanocomposites (Alves‐Silva et al., 2022; Ni et al., 2018; Xu et al., 2023), nanocrystals (Ren et al., 2023), and agro‐industrial waste (Bhat et al., 2013). When added to other compounds, this kind of package is called “composites.” The results of the studies are very promising for the food industry.…”

Effects of biodegradable and active sachets based on sodium alginate and Macaúba (Acrocomia aculeata) pulp extract on the quality of olive oil

“…The solubility in water (SW) of films was obtained according to Alves-Silva et al 1,21 The films were cut in 2 cm of diameter and dried in an oven (DeLeo A15E, Porto Alegre, Brazil) for 24 h at 105 C to determine the initial dry weight (W 0 ). The films were submerged in 50 mL of distilled water and homogenized in an orbital shaker (Tecnal TE-420, Piracicaba, Brazil) at 150 rpm for 24 h. Then, the samples were dried again at 105 C for 24 h to determine the final dry weight of the films (W f ).…”

Active carboxymethyl cellulose/polyvinyl alcohol biodegradable packaging film for shelf‐life enhancement: Effects of makrut lime essential oil on Cavendish bananas ripening and fungal spoilage

“…16 Compared to the plums treated with other coatings at 23 ± 2 C, the coating with HPMC containing 2% w/w OEO was shown to be very effective in reducing the respiration rate, ethylene production, total weight loss, and total cell count. 17 Sousa et al reported that cassava starch film containing 0.8% clove essential oil (CEO) exhibited excellent antifungal activity against Colletotrichum gloeosporioides and C. musae. The CEO-loaded film also prolonged the shelf life of banana with good quality and low weight loss.…”
