Large quantities of biological waste are generated at various steps within the food production chain and a great utilization potential for this solid biological waste exists apart from the current main usage for the feedstuff sector. It remains unclear how the usage of biological waste as compost modulates plant metabolites.
We investigated the effect of biological waste of the processing of coffee, aronia, and hop added to soil on the plant metabolite profile by means of liquid chromatography in pak choi sprouts. Here we demonstrate that the solid biological waste composts induced specific changes in the metabolite profiles and the changes are depending on the type of the organic residues and its concentration in soil. The targeted analysis of selected plant metabolites, associated with health beneficial properties of the Brassicaceae family, revealed increased concentrations of carotenoids up to 3.
Rising world population, globally changing climate, intensification and competition of biomass usage as source of bioenergy and urban horticultural practice are only a few examples which enhance people's concern about the efficient, multiple use of bio-mass and recycling of residues. Biological waste is generated at various steps within the food production chain, e.
These industries generate large quantities of biological waste and 13 million tons are produced in Germany per annum Mahro et al. Much of these wastes are either burnt or treated by oxygen-driven biological methods, such as composting, which serves a dual purpose, i. On the other hand biological food waste is a reservoir of complex carbohydrates, proteins, lipids, and nutraceuticals and can form the raw materials for commercially important metabolites. Different modes of pre-treatments, followed by recovery procedures have been applied to attain value-added products natural antioxidants, vitamins, enzymes, cellulose, starch, lipids, proteins, and pigments of spent coffee of high significance to pharmaceutical, cosmetic, and food industries Murthy and Naidu, The valorization of the solid coffee by-products in the non-food sector is also gaining more importance Murthy and Naidu, During the technological processing of fruits and berries, large amounts of solids remain containing pulp, skins, seeds etc.
