Article Synopsis
- The study developed a biodegradable packaging (PLA-PHB-CARV) for cherry tomatoes, incorporating a carvacrol-emitting sachet to enhance shelf-life at different temperatures (15 °C and 25 °C).
- Results showed that this packaging significantly reduced decay and weight loss, maintaining fruit firmness and color better than conventional macro-perforated polypropylene (PP) or non-active PLA packaging.
- The active EMAP demonstrated potential benefits like extending shelf-life, reducing the use of petrochemical plastics, and minimizing food waste during storage and distribution, making it a promising alternative for packaging fruits.
Free sugars from fruit wastes were evaluated for the production of poly(3-hydroxybutyrate) (PHB) in Paraburkholderia sacchari fed-batch bioreactor fermentations. Different initial sugar concentration, carbon to inorganic phosphorus (C/IP) ratio, IP addition during feeding and volumetric oxygen transfer coefficient (ka) were evaluated to promote PHB production. The highest intracellular PHB accumulation (66.

Bacterial cellulose (BC) was produced via fermentation in 6 L static tray bioreactors using nutrient-rich supplements derived from the enzymatic hydrolysis of sunflower meal (SFM) combined with crude glycerol as carbon source. Novel biofilms were produced using either matrices of protein isolates extracted from sunflower meal (SFMPI) alone or SFMPI matrices reinforced with nanocellulose biofillers of commercial or bacterial origin.
