Utilization and application of wet potato processing coproducts for finishing cattle1

Abstract

Wet coproducts fed to beef cattle include processing coproducts of the fruit, vegetable, juice, and brewing industries. Considerations for their utilization in beef cattle diets include quantity available, feeding value, quality of animal products produced, economics (e.g., transportation of water), storage and preservation, consumer perception, nuisance concerns, contaminants, and interactions with other diet ingredients. Potato (Solanum tuberosum) coproducts from processing for frozen food products may be quantitatively most important because the 11.3 million t of potatoes (fresh weight) processed in the United States and Canada in 2008 resulted in an estimated 4.3 million t (as-is basis) of coproduct. Chemical composition and feeding value of potato coproducts depends on the coproduct type. The names of coproducts vary among potato processors and some processors combine the different coproducts into one product commonly called slurry. The 4 main potato coproducts are 1) potato peels; 2) screen solids (small potatoes and pieces); 3) fried product (fries, hash browns, batter, crumbles); and 4) material from the water recovery systems (oxidation ditch, belt solids, filter cake). The coproducts, except the fried products, ensile rapidly, reaching pH 5 in 7 d or less. Dry matter content varies from 10 to 30% and on a DM basis varies in CP (5 to 27%), starch (3 to 56%), NDF (4 to 41%), and ether extract (3 to 37%) content among potato coproducts. Type of coproduct and frying greatly affect the energy value (0.6 to 1.6 Mcal of NE(g)/kg of DM). Composition, quality, and shelf life of beef was not affected by potato coproduct feeding in contrast to perceptions of some purveyors and chefs. Potato coproducts are quantitatively important energy sources in beef cattle diets, which, in turn, solve a potentially massive disposal problem for the food processing industry.

Evaluation of biochar-anaerobic potato digestate mixtures as renewable components of horticultural potting media

“…This waste can be fed to livestock, applied to agricultural fields as fertilizer, or dumped in landfills (Charmley et al, 2006;Nelson, 2010). During the past decade there has been increasing global interest in using these wastes for bioenergy generation (Kryvoruchko et al, 2009;Arapoglu et al, 2010;Singh et al, 2012;Wang, 2013).…”

Optimization of enzymatic hydrolysis and fermentation conditions for improved bioethanol production from potato peel residues

“…Statistics estimate that nearly two million tons of potato peel are generated per year from potato processing . PPR were incorporated in some animal feed formulation . Whereas, it was indicated that animal feed prepared from this kind of waste have low nutritional values .…”

Current options for the valorization of food manufacturing waste: a review

“…Potato peel extracts retard lipid peroxidation of radiation-processed meat without affecting its flavor. Nelson (2010) proposed to use byproducts of potatoes industry processing as cattle feed. Potato waste was a quantitatively important energy source in beef cattle diets and solved a potentially massive disposal problem; limitation to use is mostly economic, not due to quality concerns.…”
