There are basically two directions of valorization, aiming at carbohydrate and non-carbohydrate based products. Both groups are of great heterogeneity, thus candidates are usually grouped according to their functionality.
Due to this theoretical approach the production of glucose and fermentation to lactic acid, succinic acid or ethanol, the extraction of proteins and production of essential amino acids including 纬-aminobutyric acid (GABA), the extraction of ferulic acid (FA) and its conversion to vanillin, as well as the extraction of arabinoxylans (AX) seem to be feasible and of economic relevance, which will be highlighted within this review.
