Abstract
Broken rice flours of three indigenous rice cultivars were utilised for the formulation of tube type pasta (Ziti-cut) using four levels of vital gluten (14-20%, flour weight basis) and gum Arabic (0.5-2.0%, flour weight basis). The textural qualities of pasta were analysed using a texture analyser (TAXT-2i) and by descriptive sensory analysis. The pasta made from native broken rice flour and pre-gelatinised broken rice flour supplementing with vital gluten to obtain 14% protein content were compared for their instrumental texture qualities (hardness and shear strength of raw pasta as well as stickiness and adhesiveness of cooked pasta) and sensory texture analysis (colour, hardness, chewiness, smoothness and grittiness). The pre-gelatinised broken rice flour was found suitable for pasta preparation based on its firmer, larger shear strength and less stickiness and adhesiveness than its native broken rice flour. Among the three varieties, the pre-gelatinised broken rice flour of variety PR-114 with 14% protein content (supplemented by vital gluten) and 1.5% gum Arabic has been found most suitable for the pasta preparation with desirable quality attributes on the basis of instrumental and sensory textural characteristics.
