Microwave-Oven Drying of Forage Samples Collected via Esophageal Fistula

Abstract Fourteen laboratories analyzed 7 samples of tomato products with total solids content ranging from 6.5 to 40.2%. Samples were analyzed directly with the exception of samples with solids contents greater than 15%, which were diluted with water (1 + 1 for up to 30% solids and 1 + 3 for greater than 30% solids). The 2-4 g samples were dried at 100% power for 4 min. The results of the collaborative study showed good repeatability and reproducibility: 5„ = 0.16 (CV = 0.46%) and S, = 0.36 (CV = 1.06%) for the higher solids samples and S„ = 0.37 (CV = 3.76%) and Sx = 0.14 (CV = 1.41%) for samples with total solids up to 15%. Results were compared with those obtained using vacuum oven drying. No difference was seen in the results by the 2 methods at the 95% level of confidence. The microwave oven drying method has been adopted official first action as an alternative to the vacuum oven drying method for total solids.

Viable Method

In the process of working, storage, finished fodder acceptance and the preservation process of grass materials, the moisture content of forage is a very important indicator. The blast oven drying method has been generally adopted in the measurement of moisture content. The related experiment showed that the microwave oven method for grass moisture content measuring improved 200-400 times in the efficiency compared with blast oven drying method. The microwave oven method was accurate and easy operating. So, we can conclude that microwave oven method is a viable method for measuring the moisture content.

Taj Mahal

Aims: To optimize drying technique for the popular Dutch rose cultivar, Taj Mahal, by evaluating different drying methods and appraising the physical, biochemical and sensory quality of the product. Study Design: Completely Randomized Design. Place and Duration of Study: Department of Floriculture, Medicinal and Aromatic Plants, Faculty of Horticulture, Uttar Banga Krishi Viswavidyalaya, during 2019-2020 Methodology: Flowers of rose cultivar ‘Taj Mahal’, at their prime beauty i.e., half-opened bud stage, were subjected to embedded drying in silica gel at six different conditions viz. at room temperature (T1), in hot air oven at 45°C, (T2) and at 60°C, (T3) in micro-wave oven at 100% power level (T4), 80% power level (T5) and at 60% power level (T6). The quality of the ensuing dehydrated flowers was judged with respect to colour, weight, volume shrinkage and anthocyanin and carotenoid contents. Temperature during drying and time to reach optimum dehydrated condition under different drying techniques were recorded. Sensory evaluation for the quality of the products was done after six months of storage. Results: The time taken for optimum drying ranged from 120 hours in case of room temperature drying (25.1°C) to 3 minutes in microwave oven on high power i.e., 100% (130.4°C). Significant variation in final weight of the product was recorded between 18.34% to 28% of the fresh weight. Minimum shrinkage (42.85%) was noted in room drying (T1) and hot air oven drying at 60°C (43.53%). Maximum anthocyanin concentration (3.528 mg/g) was recorded in flowers dried at room temperature, whereas, minimum among the dried flowers, was recorded in microwave oven drying at 100% power level (1.439 mg/g). Maximum Carotenoid content (16.780 µg/g) was recorded in flowers dried in hot air oven at 45°C. Out of six treatments in the present study, maximum sensory score (30.38 out of 36) was gathered by T2, which was at par with T1 and T5. Conclusion: Dehydrating ‘Taj Mahal’ rose flowers by embedding in silica gel and drying under room temperature (25°C) for 120 hours or hot air oven at 45°C for 27.5 hours or microwave oven at 80% power level for 3.5 minutes can be recommended for commercial dry flower production.

African Marigold

Drying of flowers is the method of maintenance of flowers or removing water and moisture. Dehydration is most important for getting dry flowers. There are Many different types of methods use for removing moisture contain from flowers are air drying, embedded (sand, borax, silica gel, and other materials) press drying, freeze drying, microwave oven drying, hot air oven drying, Glycerin drying, freeze drying. Chrysanthemum is one of the most widely cultivated garden flowers and ranks popularity. The Chrysanthemum flower has fully double flowers with flat petals and the central disc is generally absent. Many of the commonly grown marigolds are cultivars of African and French marigolds. Flower petals of African marigold are the best source of carotene for coloring foodstuffs. From the dried flowers varied manufacture are made and use like petal embedded handmade paper, press dried flower products, candle making, pot pourri, floral jewelry etc. This dried plants and flowers materials also used in industry. For chrysanthemum embedded drying is the best in which flower shape, size, structure, colour are maintained and for marigold microwave and air drying techniques are best in size, colour, shape, colour are maintained.
