  Total phenolic content of cereal brans (wheat, rice, oat) singly and in combination (wheat: rice: oat:: 2:1.5:1.5) extracted using conventional and microwave-assisted solvent extraction (2, 3.5 and 5 min) methods were studied. Three different solvents (methanol, acetone and hexane) were used in the conventional solvent extraction using three different temperatures (50, 60 and 70°C). Methanol at 60°C was the most effective solvent, producing higher total phenolic compound content in all types brans singly and in combination than either acetone or hexane. Microwave-assisted solvent extraction significantly increased the total phenolic compound content in solvents used at 2450 MHZ for 3.5 min. Maximum total phenolic content was recorded in methanolic extracts using microwave energy at 2450 MHZ for 3.5 min. However, total phenolic content of conventional and microwave-assisted extractions at different temperatures and different time durations, respectively were significantly different (p≤0.05). The mean total phenolic content of brans ranged from 1.24-2.87 and 2.20-4.09 mg GAE g-1 by conventional and microwave assisted extraction, respectively. Among different solvents methanolic extract recorded maximum mean total phenolic content in both types of extraction systems i.e., 2.83±0.17 and 4.50±0.25 mg GAE g-1 in conventional and microwave extraction, respectively.

  Both full fat and defatted cereal brans were blended with wheat flour at different levels to prepare nutritive biscuits. Product making, sensory and texture quality were assessed to find out the most appropriate level of bran incorporation. On the basis of quality (spread ratio and sensory by a panel of judges), 20% level was selected best. Acceptability of enriched biscuits was affected with progressive storage, however, the product remained in high acceptability range upto 3 months. Free fatty acids content of biscuits were within permissible limits after three months of storage except rice bran (full fat) biscuits. Packaging material had significant impact on biscuit quality. The biscuits were stored safely in both packaging material i.e., HDPE and laminate. Microbiological study depicted that microbial count was far below the permissible limits upto three months of storage of biscuits in HDPE and laminate at room temperature. Economics of enriched biscuits revealed that wheat bran enriched biscuits were economically profitable.

  Bulgur preparation is not common in our country, despite it is known as man’s first processed food. Therefore, by making a stable nutritious product from wheat i.e., bulgur, a value can be added in consumer’s diet. Potential utilization of rain affected wheat can also be achieved by converting it into bulgur. The main purpose of this study was to standardize the process of bulgur preparation and to assess the suitability of wheat class/variety for bulgur production. Wheat of three different classes (durum, aestivum, triticale) were used for preparation of bulgur by soaking for 3.5 h at 60°C followed by pressure cooking at 15 psi 15 min-1 and drying to 10% moisture at 40°C. Pearling (8% degree of polish) and cracking operations were carried out to yield coarse, medium and fine bulgur. Sensory quality data revealed that bulgur of all fractions remained highly acceptable up to 6 months of storage at 37°C with respect to different sensory attributes. Microbial load in terms of total plate count remained well within limits during storage. The lower moisture content, ERH values and absence of aflatoxins collectively supported the increased shelf-life of bulgur. Among coarse, medium and fine fraction of bulgur from different wheat, fine fraction received high likeness followed by medium and coarser ones.
