| Abstract: | Starches isolated from 59 wheat cultivars, of diverse genetic origin but grown in New Zealand, exhibited hot-pasting peak viscosities ranging from 82 to 269 units when tested by ‘Minipaster’. Each starch was prepared without mechanical damage, without drying, and was pasted at 10% db concentration in the absence of amylase, with pH adjusted to 5.5 before pasting. Two small groups of cultivars were distinguished on the basis of unusual pasting properties, having either high peak viscosity relative to both breakdown and setback viscosities, or high setback viscosity relative to both peak and breakdown viscosities. |
