“…Glucosinolates were determined after their enzymatic hydrolysis to oxazolidinethione and isothiocyanates (Appelqvist and Josefsson, 1967). The color of the protein isolates was determined spectrophotometrically (Fontaine et al, 1945). Molecular weights of the polypeptide chains of the protein isolates were determined by sodium dodecyl sulfate electrophoresis (Weber and Osborn, 1969) with and without the use of mercaptoethanol during incubation.…”

“…Cottonseed has been recognized for many years as a potential high-protein food source (17). Extraction of the proteins from cottonseed may be accomplished by single-step procedures with aqueous alkaline or salt solutions (1,9,16,17). A two-step extraction procedure employing water or dilute salt followed by dilute alkali for the isolation of cottonseed proteins was shown to yield a product higher in nitrogen than that obtained by a single-step procedure (3).…”

Enzymatic hydrolysates of various cottonseed flours were prepared with the proteolytic enzymes bromelain, HT-200, Pronase, and trypsin. The growth of various aerobic bacteria of clinical significance in these hydrolysates was compared to that obtained with a standard casein-soybean peptone culture medium, Trypticase soy. The generation times of the majority of bacteria grown in the bromelain cottonseed flour hydrolysate were shorter than that obtained with the standard control broth. A bromelain cottonseed flour hydrolysate agar preparation supported the growth of the bacteria comparably to that of the casein-soybean agar substrate. All the bacterial colonies were larger on the bromelain cottonseed flour hydrolysate blood agar medium than those grown on the control agar. The peptones derived from the enzymatic hydrolysis of

Countercurrent extraction‐isoelectric precipitation of sunflower seed protein isolates

A countercurrent extraction-isoelectric precipitation procedure for the preparation of protein isolates from defatted sunflower seed meal is described. Using 0 . 0 4~ NaOH and a solvent : meal ratio of 20 : 1, as much as 95 % of meal nitrogen was extracted.Precipitation at pH 4.0 resulted in an isolate containing 88.4% of the meal protein.Using 0.1 sodium sulphite with the alkaline solution in the countercurrent extraction resulted in a white, bland and highly pure protein isolate. Isolated sunflower seed protein is limiting in the amino acid lysine, while other essential amino acids are present in amounts which meet the dietary requirements of chicks and human adults.
