Milling properties of peas in relation to texture analysis. Part II. Effect of pea genotype

摘要

Three smooth and three wrinkled pea varieties were evaluated for their milling behaviour in a classifier hit mill. Two of the smooth pea types were the commercially available yellow peas and the other a green wild type. The wrinkled pea varieties were mutants of the smooth wild type pea. The site of the mutation was located at the gene that affects the supply of substrate during starch synthesis, which modifies the overall composition of the pea and the size distribution of starch granules. A texture analyser with a Stanley knife set-up was used to measure the energy uptake required to split the pea varieties at different moisture contents.
