α-amylase of sorghum malt has been purified by a combination of charcoal and heat treatment, DEAE-cellulose and calcium phosphate chromatography, and gel filtration, yielding a product with a specific activity of 10,304 units per mg nitrogen. Both i

Methods of processing hake livers whereby the protein fraction and the water-soluble nutritional factors may be recovered in addition to the oil and oil-soluble vitamins, have been examined. Methods involving (a) partial tissue digestion by papain, a

The α- and β-amylases produced by the germination of kaffircorn may be either soluble or insoluble depending on the variety of the kaffircorn. The insoluble amylases occur chiefly in malts from ‘birdproof’ kaffircorn and sweet sorghum. The amyl

The main sites of fat deposition in the rock lobster are the hepatopancreas and the gonads. Data on the yield and characteristics of the oils from these organs are given. The composition of the saponifiable and unsaponifiable fractions of the hepatop

New and modified methods have been developed for the determination of amylases in kaffircorn malts because of their low β-amylase content and because of the presence of insoluble but active α- and β-amylases in malts made from certain varieties of

A method for determining the fusel oil content of kaffir beer, based on the A.O.A.C. method for alcoholic beverages, was developed. The average fusel oil content of kaffer beer is high, 227 ppm in comparison with European type beer (average 110 ppm).

Contrary to commonly accepted views, sorghum (kaffircorn) malts have been found to contain β-amylase in considerably more than traces, 18–39% of the saccharifying activity being due to the β-amylase. The α- and β-amylases have been found to dev

Unlike barley which possesses β-amylase activity before germination, sorghum grain is devoid of this enzyme. Both α- and β-amylase are produced during the germination of sorghum and, in any particular malting trial, the ratio of the enzymes to one

The effect of heat, salts and acidity on pure sorghum starch and the starch in sorghum grain and malt has been studied by determining the degree to which these factors render the starch susceptible to subsequent attack by sorghum malt amylases. This
