During the production of potato starch, potato starch, wastewater, soil, and potato starch residue are mainly produced. Wastewater can be recycled and reused, and potato starch can be applied to process food and industrial products, so what are the potato starch residue applications?

Generally speaking, about 0.5 tons of potato starch residue with a water content of 90% will be obtained from 1 ton of potatoes. Potato starch residue has three applications includes food applications, agriculture applications, and industrial applications, such as wine making, animal feed production, food production, and fertilizer production.

Potato starch residue applications

1. Food applications

Potato starch residue can be used in food applications to make high-fiber food and wine.

After the potato starch is extracted, the starch residue is very high in cellulose. It can be processed into dietary fiber products, which is beneficial to human health. In addition, potato starch residue is also a good choice for fermentation to make wine, so potato starch residue can be sold to wineries as raw materials.

2. Agricultural applications

Potato starch residues are used in agricultural applications to make animal feed.

Since potato starch residue is rich in protein and a large amount of cellulose, hemicellulose, and pectin, it can be used as a substrate for microbial fermentation to produce animal feed. This is a low-cost, high-yield project that is well worth the investment.

3. Industrial applications

Potato starch slag can be used in industrial applications to produce biogas for combustion and power generation.

Potato starch residue, as an agricultural by-product, can be used as a raw material in a biogas homogenization tank for fermentation to produce biogas, which can be used for daily use and industrial chemical raw materials. The residue after fermentation is used in agricultural production as organic fertilizer.
