Effect of Roasting on Physico-Chemical Properties and Bioactive Components of Brown Rice, Oats and Flaxseeds
Roasting is a process of dry heat treatment which involves high temperature and short time which lead to an increase in characteristic aroma, colour and texture in the food grains. The present study was undertaken to investigate the effect of roasting on the physico-chemical properties and bioactive components of brown rice, oats and flaxseeds. The effect of roasting on physico-chemical properties (colour values viz., L*, a*, b*, moisture, protein, fat, fibre, ash content, carbohydrates and energy value) and bioactive components (total phenolic content and antioxidant activity) was evaluated. The changes in colour values were observed and it was found that the L* value of brown rice, oats and flaxseeds decreased from 56.23, 75.20 and 44.36 to 53.78, 69.63 and 33.15, respectively, whereas a* values increased after roasting. The bioactive components viz., total phenolic content and antioxidant activity became higher in roasted brown rice, oats and flaxseeds and the values for total phenolic content increased from 75.21 to 76.03 mg GAE/100g, 95.00 to 96.29 mg GAE/100g and 3.75 to 4.28 mg GAE/100g, respectively, whereas the values for antioxidant activities increased from 49.78 to 50.39 %, 14.28 to 15.86 % and 76.19 to 76.92 %, respectively for brown rice, oats and flaxseeds.
Design and Development of a Self-propelled potato digger for Small land holdings
A self-propelled potato digger for small landholders was developed and evaluated. The developed prototype comprises of power transmission unit, digging unit, and separating/collecting unit of the self-propelled potato digger designed to address the needs of the hilly area. All the components were connected to a central support structure via nut bolts and welding, which was powered by a diesel engine (6.71 kW). The developed potato digger was evaluated at different machine and performance parameters. For all the treatment combinations, the maximum digging efficiency (95.37 percent) and the lowest damage percentage (3.24 percent) were observed at a treatment combination of forward speed of 2 kmh-1, rake angle of 260, and vibrating frequency of 900 rpm.
DESIGN OF AN ATESTA FORCED CONVECTION DRYER WITH REDUCED ENERGY CONSUMPTION
This work aims to improve the technical and economic performance of the ATESTA dryer by including a device with forced convection. This innovation aims to increase the quality of the dried mango and the dryer’s efficiency. For this purpose, a technical diagnosis of the ATESTA natural convection dryer has been carried out. The results of the technical diagnosis combined with a Functional Analysis (FA) and a Multicriteria Analysis (MCA) enabled the sizing of the device with forced convection integrated into the ventilation circuit. This new device comprises an air extractor, a potentiometer, and installation support. The performances of the ATESTA dryer with integrated forced convection compared to those of the ATESTA dryer with natural convection show a net improvement of 68 to 100% of the quality of the dried mangoes of 1st choice, a reduction of 40% of the drying time, of 34% of the consumption of butane gas; a 40% saving of the energy cost. Drying trials with the improved ATESTA gas dryer will be carried out on other tropical products (pineapple, papaya, etc.) to meet the needs of food processors in the West African sub-region.
Response of root characters of transplanting redgram (Cajanus cajan L.) varieties under different nursery technique
The field experiment was conducted at Agricultural College and Research Institute, Madurai at kharif 2021 to evaluate the effect of different nursery technique on root characters of different redgram crop varieties. The experiment was laid out in Factorial Randomized Block Design (FRBD) and replicated thrice. The first factor comprised of three different nursery techniques such as portray nursery, mat nursery and polybag nursery and the second factor comprised of 7 redgram varieties of different duration such as short duration (APK 1 and VBN 3), medium duration (Co (Rg) 7) and long duration (ICPH 2671, ICP 7035, ICPH 2740 and Co 8). The experiment concluded that, in all redgram varieties polybag nursery achieved the highest root length, root volume, root nodules and root shoot ratio at (30.80 cm, 0.71 cc, 14.35 and 1.39). This will improve the growth and development of redgram crop.
Correlation studies between temperature variables during different phenophases and flower quality parameters of Hybrid Tea rose cultivar Minu Pearle
Floral characters of rose cultivar Minu Pearle influenced in varied degree by studied temperature related weather variables. Correlation between floral characters and weather parameters studied with 6 different phenological stages (P1- bending to FBE, P2- FBE to SR, P3- SR to full bloom, P4- bending to SR, P5- FBE to full bloom and P6- bending to full bloom). Among the characters studied, all the characters negatively correlated with all the temperature related weather variables, except accumulated diurnal variation of temperature at all the phenological stages. Improvement in floral characters was observed with wider day and night temperature along with higher number of bright sun shine hours during the peak flowering stage (December to January).
