Physicochemical characterization of an arabinoxylan-rich fraction from brewers' spent grain and its application as a release matrix for caffeine

A bibliometric analysis on potential uses of brewer's spent grains in a biorefinery for the circular economy transition of the beer industry

“…Among the most explored products from BSG are the arabinoxylans, which can be recovered from alkaline pretreatment. As BSG is an excellent source of bioactive compounds, the conventional arabinoxylan extraction method also extracts a large amount of ferulic acid, a biologically important phenolic compound 91 . Based on the literature, 1 ton of BSG can produce 133 kg of arabinoxylan, which means a yield of up to 50% of untreated BSG 90 .…”

Arabinoxylans matrixes as a potential material for drug delivery systems development - A bibliometric analysis and literature review

“…On the other hand, integrating materials derived from agri-food by-products into the circular economy is paramount for sustainable resource management and waste reduction. By utilizing AX extracted from agri-food by-products, such as maize bran, wheat bran, and brewers’ spent grain, researchers can contribute to the valorization of these by-products, thereby reducing waste and encouraging the effective utilization of agricultural resources [ [25] , [26] , [27] ]⁠. On the other hand, AX utilization in the development of functional materials, such as films, coatings, and hydrogels, aligns with the principles of the circular economy through the promotion of the reusability and recyclability of agro-food by-products [ 17 , 18 , [27] , [28] , [29] ]⁠.…”

Production of xylose through enzymatic hydrolysis of glucuronoarabinoxylan from brewers’ spent grain

“…Various pretreatment options have been reported to fractionate, solubilize, hydrolyze, and separate cellulose, arabinoxylan (AX), and lignin components (Saha 2003 ). Specifically, AX can be extracted using water or hydrothermal pretreatment (Kaur et al 2020 ), alkaline pretreatment (Pérez-Flores et al 2019 ), ultrasound-assisted extraction (Reis et al 2015 ) and microwave (Coelho et al 2014 ). The AX of BSG are usually extracted by a well-established sequentially procedure using solutions of KOH with increasing concentration of 0.5 M, 1 M, and 4 M follow for ethanol precipitation (Mandalari et al 2005 ; Vieira et al 2014 ).…”
