Response surface optimization for development of Dragon fruit based ready to serve drink
Get PDFDragon fruit based ready to serve drink (RTS) was formulated using dragon fruit (60-80% v/v), grape juice (0-10% v/v) and sugar syrup (2-6% v/v). The juice concentrations were optimized using response surface methodology (RSM) following box-behnken design (BBD) for obtaining blended RTS drink with higher functional and nutritional characteristics like total soluble solid (TSS), titratable acidity, ascorbic acid content, total phenol content, colour and sensory evaluation. Results showed that there was significant (P<0.01) effect of incorporating grape juice and sugar syrup which further improved the organoleptic properties of the blended RTS.Optimum juice percentages obtained for the best blend formulation were,dragon fruit (70%), grape juice (5%) and sugar syrup (3%), respectively. The beverage was observed to be acceptable in terms of its nutritional value and overall acceptability
Sensory and nutritional evaluation of beverages developed using malted ragi (Eleusine coracana)
Get PDFFive milk based beverages were developed by supplementing malted ragi and were organoleptically evaluated for sensory attributes by semi-trained panel of 10 judges. Control samples were developed by using milk, fruits (banana, kiwi, strawberry, papaya and mango) and honey and in test samples malted ragi was added at different levels ranging from 5-15 percent. Results revealed that banana based malted ragi beverage supplemented with 5 percent malted ragi was overall highly acceptable in terms of all sensory attributes. The most accepted level was chemically analysed for proximate composition, amino acids, vitamins, minerals, available carbohydrates and antinutritional components by using standard methods. The most acceptable malted ragi beverage was estimated to have 11.78±0.06 g crude protein, 6.81±0.51 g of crude fat, 1.21±0.07 g of crude fibre, 27.44±1.03 g of carbohydrates, 594.3±4.5 mg of tryptophan, 517.6±23.2 mg of methionine, 372.3±8.5 mg of lysine, 172.6 mg of calcium, 3.73 mg of iron, 102.2 mg of phosphorus and 0.596 mg of zinc per 100 ml. The anti-nutritional components were 155.8±11.3 mg of phytates, 15.4±2.3 mg of total phenols and 0.32±0.01 mg of trypsin inhibitor activity. Total sugars were found to be 5.44±0.21 g, 3.16±0.15 g of reducing sugars, 2.28±0.14 g of non-reducing sugars and 1.06±0.05 g of starch. It may be concluded that malted ragi can be utilized successfully up to 5 percent level to prepare beverages with high nutritional value without imposing negative impact on sensory attributes which may prove a boon to osteoporotic patients

Genetic diversity analysis for various morphological and quality traits in bread wheat (Triticum aestivum L.)
Get PDFThe present investigation was carried out during 2011-12 in a randomized block design (RBD) with 35 diverse wheat genotypes to assess the genetic diversity for various morphological and quality traits. The analysis of variance for grain yield and its contributing components namely days to 50% flowering, days to maturity, productive tillers, plant height, spike length, spikelets pet spike, grains per spikelet, biological yield, harvest index, 1000 grain weight, grain yield and gluten content showed highly significant differences (at <1% level of significance) among the genotypes under present study. High heritability along with high genetic advance and high phenotypic coefficient of variation (PCV) and genotypic coefficient of variation (GCV) for grain yield (g), biological yield (g), harvest index (%), spike length (cm) and 1000 grain weight (g) indicated substantial contribution of additive gene action in the expression and thus selection would be effective for genetic improvement of these traits for improving grain yield in wheat. On the basis of multivariate analysis, 35 genotypes were grouped into ‘6’ clusters based on genetic divergence (D2 ) value. The compositions of clusters revealed that the Cluster IV contained the highest number of genotypes (9) followed by Cluster II (8), Cluster VI (8) and Cluster III (7). The highest inter cluster values were recorded between cluster III and V (8357.19) followed by cluster IV and V (7513.88), cluster IV and VI (6009.44) and cluster III and VI (5530.40) exhibiting wide genetic diversity. Among different traits, biological yield (32.12%), productive tillers (28.74%), harvest index (26.71%), plant height (24.20%), grain yield (19.23%) and grains per spikelets (14.89%) had maximum contribution to total genetic divergence, therefore may be used as selection parameters in transgressive segregants. Selection of genotypes from the clusters may be used as potential donors for further hybridization programme to develop genotypes with high yield potential in wheat crop

Get PDFThe study was designed to evaluate the effect of leaf powder of Giloy (Tinospora cordifolia) in fish feed on survival and growth of post larvae of Catla catla. The experiment consisted of five treatments (T1, T2, T3, T4 and T5) in triplicate. The artificial feed was prepared from de-oiled groundnut cake (49.5%), de-oiled rice bran (49.5%) and vitamin – mineral mixture (1%). The leaf powder of giloy was incorporated into larval feed at various rates. In treatment T1 (control), no leaf powder was incorporated in the feed. In T2, T3, T4 and T5 leaf powder was mixed at the rate of 0.25%, 0.5%, 0.75% and 1%, respectively. One hundred post larvae of C. catla of uniform size (7.3 mm length, 1.5 mg weight) were stocked in each of 5×3=15 tanks. The larvae were fed twice in a day. The water quality parameters were regularly monitored. The survival rate of post larvae in T1, T2, T3, T4 and T5 were recorded as 95.3, 94.3, 97.0, 98.6 and 100%, respectively. Post larvae fed with diet incorporated with 1% leaf powder achieved significantly enhanced (P< 0.05) specific growth rate (6.97%), feed conversion ratio (2.41) and gross conversion efficiency (0.415). The study revealed that giloy leaf powder has very good growth promoting potential in raising post larvae of carp. Thus, it is recommended that the leaf powder of giloy may be incorporated in fish feed upto 1% for enhancing growth and survival of post larvae of carp fishes up to fry stage
