Yield of Soya Paste (Okara) Influenced by Some Mechanical Parameters of an Automated Grain Drinks Production Machine

Soya bean paste (okara) is the by-product obtained after extraction of aqueous milk from soya bean. Large quantities of the paste are generated as by-product obtain the process of extracting the aqueous liquid from soya beans and in the production process of tofu. Several research works have reported on quantity of okara to be generated from soya beans. According to Liu [1], 1.1 pounds of okara can be generated from 1 pound of soya beans, while Riaz [2], stated that 1 kilogram of soybeans used for soymilk processing can generates between 1.4-1.8kg of okara. According to Africa Do Business Limited (2012), 1.2kg of fresh okara is produced from 1 kg of soya beans processed for manufacturing of tofu [3].
