The accumulation of petroleum-based plastics causes economic and environmental concerns which necessitate a comprehensive search for biodegradable packaging materials. Brewer's spent grain (BSG) is an interesting by-product, which is one of the main wastes of beer production in Europe. BSG could offer added value in the food packaging sector owing to the significant amount generated annually, high biomaterials content, and low market value. Herein, the significance of various biorefinery techniques (physical, chemical, and biological) for the extraction of high-value products (such as protein, cellulose, hemicellulose, lignin, and phenolic compounds) from the BSG are comprehensively examined. BSG-derived biodegradable films and coatings for food packaging are critically evaluated. Finally, techno-economics, environmental impacts, energy consumption, regulations, challenges, and prospects are also critically evaluated. The best biorefinery system necessitates a balance between extraction efficiency, energy consumption, environmental impact, tangible upscaling, and operating cost. The mechanical dewatering of BSG before extraction, including the physical pretreatments, utilization of green solvents, the integration of the solvent recovery system, and the combination of two or more biorefinery techniques could reduce the energy requirements, greenhouse gas emissions, and increase the recovery yield of biomaterials. Cellulose, lignin, xylitol, and arabinoxylan are recommended as the most promising components from BSG for food packaging applications.

Abstract
The maturity stage of carrot and the temperature strategy during storage are essential factors in maintaining storage quality during long-term storage. The aim of the study was to examine the effect of maturity and storage strategy on storage quality in different cultivars of carrot (Daucus carota subsp. sativus). Two cultivars, ‘Nominator’ and ‘Romance’, harvested at three different maturity levels were stored with different temperature strategies in small-scale experimental stores. The different maturity levels were obtained by different sowing dates. The study was conducted over 2 years and storage seasons in 2019-2020 and 2020-2021. The carrots were stored with three different temperature strategies with stable temperature at 0, 2 or 0°C interrupted with intervals of 2 weeks with 4°C in February and in March. After six-months storage we found that weight loss was higher (7.8%) after storage when the temperature was not stable during storage (fluctuations up to 4°C in February and March) than at stable temperatures at 0 or 2°C. The number of healthy roots after storage was highest in the most mature carrots (91%) while there were less healthy roots in the least mature roots (85%) (P<0.05). Diseases detected after storage were gray mold (Botrytis cinerea), liquorice rot (Mycocentrospora acerina), tip rot, crater rot (Fibularhizoctonia carotae), Fusarium rot (Fusarium spp.) and cavity spot (Pythium spp.). There was significantly more liquorice rot in Nominator (1.9%) than in Romance (0.6%). There was more tip rot in the least mature carrots (3.3%) compared to the other two maturity levels (1.3 and 1.5%).
