Spent Grain

Brewer’s spent grain (BSG) is a processing waste generated in large quantities by the brewing industry. It is estimated that over 38 million tons of BSG is produced worldwide each year and is usually used as animal feed, composted, or thrown into landfills. BSG contains valuable nutritional components, including protein, fiber, and antioxidants. Due to its brittle texture, strong nutty flavors, and dark color profiles, BSG has seen limited use in food products for human consumption. The objective of this study was to develop a palatable chip product that maximized the level of inclusion of BSG. Chips were produced that contained BSG levels ranging from 8% to 40%, and the physical and sensory properties of the chips were evaluated. Spent grain samples were provided by Iron Monk in Stillwater and were dried at a low temperature and milled into flour for use in the chip formulation. BSG chips were evaluated for water activity, color, and texture (fracture force). An informal sensory evaluation was conducted to evaluate flavor, texture, and probability of purchase using a 5-point hedonic rating scale. Results showed that there were no significant differences in the texture of the chips containing different levels of BSG. The color measurements showed no significant differences between L ∗ and a ∗ values for the chips containing different inclusion levels of BSG, but there were some differences in the b ∗ values. Results from the sensory evaluation showed that consumers preferred the texture of chips with 40% BSG over chips with 8% BSG, and they were also more likely to purchase the 40% BSG chips. There were no significant differences in flavor among the chips containing different inclusion levels of BSG. These results suggest that, for a chip-type product, BSG inclusion levels up to 40% are possible with positive consumer responses. Development of an alternative value-added product represents an opportunity for breweries nationwide to turn a processing waste into a future asset.

Biosynthetic capabilities of microbes have solved several hurdles in the human welfare. Microbes have served and continue to serve as imperial candidates in both production and management strategies. Microbe mediated techniques has emerged as ecofriendly and sustainable alternative to their synthetic counterparts. Fruit based industries produces large volumes of solid and liquid wastes contributing to increase in pollution load. Disposal of these waste not only represent loss of valuable biomass but also leads to substantial increase in Biological Oxygen Demand (BOD) and Chemical Oxygen Demand (COD). However, in spite of their pollution and hazard aspects, in many cases, fruit processing wastes have a promising potential for being chief raw materials for secondary industries. This chapter summarizes microbe mediated fermentative utilization of fruit waste, for the production of value added products like organic acid, single cell protein, bioplastics, enzymes and biogas.

Summary The chemical characterization of the pulp, peel and seeds of cocona (Solanum sessiliflorum Dunal) was determined. In artisanal fruit processing, 26.3% of peel and 9.7% of seeds were obtained. The seeds showed a high potential for the development of value-added products because of their dry matter contents (23.46%) as follows: carbohydrate (69.37% dry basis (d.b.)), nitrogen (3.18 g/100 g of seed d.b.), K (0.023 g/100 g of seed d.b.), Fe (0.0185 g/100 g of seed d.b.) and dietary fiber (21.27 g/100 g of seed d.b.). The carbohydrate, dietary fibre and mineral contents of the pulp, peel and seeds also highlighted the agroindustrial potential of the fruit in that these constituents could be used to develop functional foods, food additives, preparations for functional diets and dietary supplements.

Rearing Conditions

Bioconversion is the process whereby nutrients are recovered from organic waste products, often by flies, to produce value-added products such as protein for animal feed and lipids for biodiesel production. Currently, research and industry focus on a select few fly species for use in bioconversion that are generalists in their feeding behaviour, the black soldier fly, Hermetia illucens L., and the housefly, Musca domestica L. More investigation is needed on species of flies that are more suited to underutilised waste streams, including meat processing waste. Species of flies that breed in carrion, such as blowflies (Calliphoridae) and flesh flies (Sarcophagidae) can be used to reduce meat processing waste and produce a valuable source of protein. In this review, we propose more investigation and use of a wider range of fly species for bioconversion of organic waste. Four blowfly species are recommended for use in the bioconversion of meat processing waste or a mixture of manure waste and meat processing waste. Chrysomya chloropyga (Wiedemann) is a large mammal carcass specialist and has been found to be effective at recovering nutrients from abattoir waste within four days and producing large larvae in the process. Chrysomya putoria (Wiedemann) and Chrysomya megacephala (Wiedemann) naturally breed in carrion and faeces, are associated with pit latrines and respond well under mass rearing conditions, with high egg production. These species would be recommended for a large-scale bioconversion facility that receives mixed waste streams including manure and animal remains. Lucilia sericata is known to produce antimicrobial compounds that assist in wound healing and has been frequently bred and studied and responds well to lab and mass rearing conditions. We recognise the potential obstacles to using alternative species in industrial-scale bioconversion facilities and pose future directions for research to overcome these challenges.
