Optimization of microwave assisted extraction parameters of betalains pigment from Celosia argentea var. cristata using box behnken design
Full text linkThe use of effective extraction technique would be beneficial for degrading the cell wall leading to efficient leaching out of pigments with less degradation of pigments. The pigment extracted using this technique will be use as a replacement of synthetic colorant in food industry and pharmaceutical. The main objectives are to extract betalains pigment, study the effect of extraction parameters on response and optimization of parameters for pigment production. In microwave assisted extraction of betalains pigment, parameters such as microwave power of 80, 160 and 240 W, treatment periods of 30, 60 and 90 s and solid to solvent ratio of 1:20, 1:30 and 1:40 g/ml were employed. Effect of these parameters were studied on response quantification of betalains and the parameters were optimized using Response Surface Methodology. Numerical analysis and effect of parameters on quantification of betalains was also studied. It was observed that solid to solvent ratio was observed to be highly significant affecting the extraction yield. The optimal process variables and response obtained for microwave power, treatment period, solid to solvent ratio and quantification of betalains are 200 W, 66 s, 1:20 g/ml and 9.11 mg/g, respectively. Microwave assisted extraction is found to be one of the promising extraction techniques for betalains extraction
Briquetting of mango seed shell: effect of temperature, pressure and binder
Full text linkMango peel and stone are the major process wastes of mango processing industry. In this study, an attempt was made to explore the economic potential and operational feasibility of outer hard fibrous pericarp of mango stone as a source of energy by adopting briquetting technology. Mango seed shell briquettes were prepared using hot and cold compression techniques to evaluate the influence of temperature (100 and 150°C), applied pressure (150 and 200 kg.cm-2) and binder level (sodium silicate: 15 and 20%). Properties of the briquettes such as density, durability, shatter indices and calorific value were determined. The briquettes produced by hot compression have the maximum and minimum densities of 1281 and 1184 kg.m-3, respectively. On the other hand, corresponding values in cold compression were 1127 and 1032 kg.m-3, respectively. Durability ranged from 88.04 to 94.31% in hot compression, while the range was 85.93 to 91.09% in cold compression. Among the two methods, maximum per cent (95.21%) weight was retained by the briquettes made by hot compression with high temperature and pressure combinations. The calorific value of mango stone shell was found to be 4468.67 kcal.kg-1. Minimum calorific value of 3546.23 kcal.kg-1 was noticed when briquettes were made with 20% binder level. High calorific value with good stability and durability of mango seed shell briquettes reflected its potential as a feasible energy source
Effectiveness of three manually operated weeding tools for farm women
Full text linkIn this study, khurpi, three tyne hoe and twin wheel hoe were evaluated in terms of performance, grade of work and comfort for gram crop with eight farm women (subjects). Weeding operation between the rows of gram crop was carried out with these tools during December-January, when the average ambient temperature and relative humidity were 18OC and 70%, respectively. The result of this investigation indicated that weeding with khurpi and twin wheel hoe could be graded as moderately heavy work, whereas weeding with 3-tyne hoe could be graded as heavy work. However, weeding with khurpi required less energy (9.39 kJ/min) than twin wheel hoe (9. 67 kJ/min). High energy expenditure (12.89 kJ/min) was observed in case of 3-tyne hoe. In terms of higher output, twin wheel hoe was observed best (179 man-h/ha) than 3-tyne hoe (302 man-h/ha) followed by khurpi (447 man-h/ha). Khurpi had shown highest weeding efficiency (92.1 to 94.8 %). Improved weeding tools such as twin wheel hoe and 3-tyne hoe reduced physical exertion and fatigue to make farm women comfortable
Transforming Agriculture through Innovation – Indian Perspective
No full textAgriculture is oldest and largest sector in India which employs more than 54.6% of workforce along with significant contribution in country’s economy (17.8% GVA added for the year 2019-2020). According to FAO, India is the largest producer of pulses (25% of global production) and milk, second largest producer of rice, wheat, sugarcane, cotton and groundnuts. India is also second-largest producer of fruit and vegetables, accounted 10.9% and 8.6% of global production respectively
Transforming Agriculture through Innovation drive
No full textProminence of Agriculture over the years Agriculture constantly being the backbone of a country’s economy and prominently being the only promising sector worldwide contributes to about 6.4% of GDP to the Indian economy which is much higher than the world’s average according to the data published in 2021 Statistics Times. The food sector as well as the agriculture sector are facing challenge to feed the estimated global population of 9.7 billion people by 2050 and 10.4 billion people by 2100 with the available diminishing land resources. Farming is a complex; unpredictable and individual business,on the other hand the modern agriculture has always been threatened by constraints and challenges. To tackle this, one needs to provide creative solutions. This is where Innovation comes to picture
Automation for Aatmnirbhar Krishi
No full textLike any other big farmers, Ramlal was also tired of small and big problems in farming. Despite having good land, plenty of water, good means of transportation, they were facing many issues due to lack of labour. He had almost decided to stop farming or to hand over it to someone and get shied to the city with his elder son. In this regard, Ramlal went to the nearby Krishi Vigyan Kendra to take the next decision as aer discussing it with the experts there. From the discussion, he saw that many facilities of farming are now simplied due to technology, without depending on labours. Of course, all these technologies are more convenient for rich farmers or big land holders, though in the future, when the demand increases, the prices of these services will also decrease and they will come within the reach of common farmers as well
Abundant opportunities for mechanizing farm activities
No full textIndeed, India is an agrarian economy. With the appropriate climatic conditions and the rich fertile land, the country has huge potential to become one of the leading producers of various agriculture products. With the adoption of advance agricultural equipment and tech-driven methods, we have huge potential to improve productivity. If we look at the Agriculture machinery industry in India, we undoubtedly hold the top position in annual production and sales of tractors, which is almost half of the global volume. The domestic sales of tractors had touched 900,000 units and exports were at 100,000 units. So we have a strong market for tractors, which basically are the prime movers for most land preparation implements. The issue here is that although we have mechanized most of the land preparation activity, but there is a lot more to be done on agriculture mechanization. There are abundant opportunities for mechanizing other farm activities to boost productivity namely – transplanting, precision planting, crop protection and harvesting
