A SWELLING POWER TEST FOR SELECTING POTENTIAL NOODLE QUALITY WHEATS

A swelling power test was developed for selecting wheats suitable for the manufacture of Japanese white noodles. The test is rapid, uses less than 0.4 g of sample and is applicable to starch, flour, wholemeal or Quadrumat Junior flour samples. Swelling power values correlated significantly (P < 0.01) with peak paste viscosity monitored on the Rapid Visco Analyser and with noodle eating quality. Paste viscosity of flour or starch is considered an important characteristic governing noodle quality. The swelling power test provides a suitble predictive method for identifying noodle quality wheats in the early stages of a breeding programme.
