Description

In order to study the effect of irradiation of corn grains on the starch extraction and quality of by-products, the grains were subjected to different doses of gamma-rays. It was generally found that irradiation led to increase the water absorption during steeping. This increase in the water absorption increases the yield of starch and facilitates the removal of hulls and germ. However, at higher dose (1,000 Krad) the yield of starch decreses. The results are discussed on the basis of effect of hydrogen bond protein denaturation, and formation of volatile compounds. (orig.)

Abstract (German)

Zum Studium der Wirkung einer Bestrahlung von Maiskoernern auf die Staerkeextraktion und die Qualitaet der Nebenprodukte wurden die Koerner unterschiedlichen Strahlungsdosierungen von Gammastrahlen ausgesetzt. Allgemein wurde festgestellt, dass die Bestrahlung zu einer Erhoehung der Wasseraufnahme waehrend des Quellprozesses fuehrte. Dies fuehrte zu einer Erhoehung der Staerkeausbeute und erleichterte die Abtrennung der Schalen und der Keime. Bei hoeheren Dosierungen (1.000 Krad) verminderte sich die Staerkeausbeute. Die Untersuchungsergebnisse werden auf der Grundlage der Wirkung einer Eiweissdenaturierung und der Bildung von fluechtigen Verbindungen diskutiert. (orig.)
