Soya Fluff

Preparation of Raw Materials. Defatted soy flours used in this study were Soya Fluff-200W (Central Soya Inc., Fort Wayne, IN) and Extra Acted Soy Flour 200-1 (A.E. Staley, Decatur, IL). These two flours met the requirements proposed by Smith (9 ). ... 

To vary the Nitrogen Solubility Index (NSI) of the Soya Fluff 200W (NSI 65), 600-g batches of flour were heated on baking pans in an oven (135 C) for 2, 4 and 12 hr. These heat treatments reduced the 65% NSI flour to 51, 46 and 14% NSI, respectively. Extra Acted Soy Flour 200 I, with an NSI of 55.8%, was also included in this study without any heat treatment. 

Ionic strength of the Soya Fluff 200W was varied by adding various amounts of NaCl and CaCl2. Amounts of each salt added to the flour were 0.2, 1 and 2%, based on flour weight.
