Abstract:
The effect of extrusion processing using Wenger X-5 extruder on the quality of products of rice-legume (75:25) blends was investigated. The products were palatable and had a good texture. The nutritional quality of protein in the extrudates was significantly improved. The protein efficiency ratio values of rice-soybean, rice-bengal gram and rice-black gram products were: 2.25, 2.30 and 2.28 as compared to 2.10, 1.89 and 1.98 for the respective raw blends. Extrusion processing reduced the phytates in the products to the extent of 20.3 to 26.8%.

Protein Modifications in the RER
Broadly, these modifications can be categorized into four main categories — glycosylation, formation of disulfide bonds, assembly of protein subunits, and specific proteolytic cleavages like removal of signal sequences.
