Defatted pumpkin (C. pepo andC. maxima) seed flour has potential food uses because of its high protein content, 61.4±2.56%. The functional and electrophoretic properties of the defatted flour were investigated. Polyacrylamide gel electrophoresis and electrofocusing indicated 14 bands of water-soluble protein subunits with isoelectric points between 3.81–8.08 and apparent molecular weights between 19,200 and 97,000 daltons. Minimum nitrogen solubility was observed at pH values between 3.0–7.0… Expand
Nitrogen extractability and functional properties of defatted Erythrina variegata flour
Abstract Defatted Erythrina variegata flour was prepared from dehusked seed meal by hexane extraction of residual oil. The resulting flour had 403 g kg −1 of protein as compared to 282 g kg −1 in theExpand
Chemical and functional characterization of Gum karaya (Sterculia urens L.) seed meal
Abstract Chemical and functional characterization of the meal of Gum karaya ( Sterculia urens ) whole and dehulled–defatted seed were investigated. Dehulled–defatted seed meal (DDSM) contained 40.7%Expand
Physicochemical and functional properties of whole and defatted meals from Mexican (Cucurbita pepo) pumpkin seeds

Preparation of wood apple (Feronia limonia L.) seed protein concentrateand evaluation of its nutritional and functional characteristics.
Wood apple (Feronia limonia L.) seed protein concentrate (WSPC) was prepared and its properties were compared with the wood apple seed meal (WSM). The protein content was found to be 33.79 and 77Expand
SOFTENING OF PUMPKIN SEEDS (CUCURBITA MOSCHATA) BY ALKALINE MACERATION
ABSTRACT The nutritional value of pumpkin seeds is widely recognized. This article shows that alkaline maceration of pumpkin seed makes them soft and improves their market acceptability as anExpand
Influence of enzymatic hydrolysis and enzyme type on the nutritional and antioxidant properties of pumpkin meal hydrolysates.
TLDR
Hydlysates from by-products of pumpkin oil-processing might serve as alternative sources of dietary proteins with good nutritional quality, and protection against oxidative damage, as well as providing protection against lipid peroxidation in a linoleic acid model system. Expand
