Ccxvii. the Proteolytic Enzymes of Sprouted Wheat. Iii

نویسنده

  • J. D. MOUNFIELD
چکیده

IN two previous communications the author [1936, 1, 2] has described the chief properties of the proteinase and dipeptidase found in aqueous extracts of sprouted wheat. The present paper is a continuation of these studies and deals primarily with the action of the proteinase on gelatin, ovalbumin and on the principal proteins of wheat, namely, gliadin and glutenin, both separately and in the form of gluten. EXPERIMENTAL

Lxxx. the Proteolytic Enzymes of Sprouted Wheat

ALTHOUGH previous work has shown the presence of proteolytic activity in wheat and wheat flour, attention has been focused on the fate of the wheat proteins rather than on the nature of the enzymic processes [Sharp and Elmer, 1924; Johnson et al., 1929; Brownlee and Bailey, 1930]. Although the proteolytic activity of wheat is very slight [Cairns and Bailey, 1928; Herd, 1931; Landis, 1935] it ma...

The Effect of Proteolytic Activity on the Technological Value of Wheat Flour from Pre-harvest Sprouted Grain

Investigations were conducted on the level of the overall proteolytic activity in flour fractions as well as fine and bruise bran, obtained from four varieties of wheat (‘Zyta’, ‘Pegassus’, ‘Sukces’, ‘Tonacja’), subjected to pre-harvest sprouting. Moreover, an analysis was conducted on the effect of pre-harvest sprouting on the functional properties of flour, determining the physical properties...

Effect of Pre-Harvest Sprouting on Physicochemical Properties of Starch in Wheat

Pre-harvest sprouting (PHS) in wheat (Triticum aestivum L.) occurs when physiologically mature kernels begin germinating in the spike. The objective of this study was to provide fundamental information on physicochemical changes of starch due to PHS in Hard Red Spring (HRS) and Hard White Spring (HWS) wheat. The mean values of α-amylase activity of non-sprouted and sprouted wheat samples were 0...

Interaction of maternal photoperiod history and food type on growth and reproductive development of laboratory meadow voles (Microtus pennsylvanicus).

The interaction of maternal photoperiod history and four diets were tested by measuring body growth, reproductive development, and pelage development in 9-week-old juvenile meadow voles. Meadow vole dams were housed in long daylengths (LD; 14 h light/day), short daylengths for 2 weeks (SD; 10 h light/day), or short daylengths for 26 weeks (PR; photorefractory) prior to mating. Immediately follo...

The Effect of Bug Damage on Physicochemical, Electrophoretic and Quality Factors of Wheat Gluten

One of the most important forms of preharvest damage to wheat is caused by sunn pests. The insects insert their mouth parts into the immature grain and while injecting their saliva suck the milky juices. Flour from damaged wheat results in low baking performance due to the bug proteolytic enzymes’ injected which cause the breakdown of gluten structure in the dough. In the present study three wh...
