Barley grains

Diastase or amylase is formed when malt is produced by the germination of barley grains. Malt is therefore a good source of the enzyme. Diastase is also secreted by the salivary glands (when it is known as ptyalin), and also by the pancreas. Its function is to hydrolysef starch to a mixture of maltose and dextrin ... [Pg.512]

Weigh the samples [strawberry, rice grain, 25 g wheat grain, barley grain, 10 g rice straw, 5 g soil (dry weight basis), 30 g] in round-bottom flasks of appropriate volumes (500- or 300-mL). For soil samples add 40mL of IN sulfuric acid and 120mL of acetone to the flask, and for other samples add 20 mL of 1 N sulfuric acid and 60 mL... [Pg.534]

Transfer the concentrated crop sample extract (strawberries, rice grain, barley grain and rice straw) into a 50-mL separatory funnel with a small volume of water. Extract the solution three times with 10 mL of a chloroform-methanol (3 1, v/v). Dry the chloroform-methanol layer with a small amount (about 8 g) of anhydrous sodium sulfate on a glass funnel and transfer the dried solution to a 100-mL separatory funnel. [Pg.535]

Extract the chloroform-methanol layer from the strawberry, rice grain, barley grain and rice straw samples twice with 30 mL of 0.1 M phosphate buffer solution (pH 7.0). Since an emulsion is formed, the first extraction should be conducted with very gentle shaking. Centrifuge the extract at 2500 rpm for 10 min, when an emulsion is formed. Discard the chloroform-methanol layer. [Pg.535]

Sample storage stability Prohexadione-calcium in strawberry, rice grain, rice straw, wheat grain and barley grain is stable at -20 °C for 40, 140, 60, 80 and 100 days, respectively. Approximately 88% of the applied prohexadione-calcium remained in soil when stored at —20 °C after 80 days. [Pg.538]

Enzymes are also added to catalyze the hydrolysis or saccharification of starch. Malt produced by the germination of barley grain contains the enzymes that catalyze this hydrolysis. Sometimes called diastase, the enzymes are primarily a- and 6-amylase. Glucoamylase is a pure enzyme that can now be used. Both diastase and glucoamylase hydrolyze starch polysaccharide to the disaccharide, maltose. For fuel grade ethanol production, hydrolysis takes place at temperatures ranging from about 120°F to 140°F (50°C to 60°C) for about 1 hour. The final product of hydrolysis is called a wort. Solids can be filtered from the wort before continuing. [Pg.279]
