Empirical models to correlate the basic physical and chemical indices of modified rice bran and mustard oil

This research was conducted to evaluate physical and chemical properties of organic mineral additive incorporated by Saccharomyces cerevisiae which was cultivated on different growth media consisted of cassava flour and rice bran, respectively. Treatment was arranged on completely randomized design consisted of rice bran without inoculants (RBo), rice bran with inoculants (RBi), cassava flour without inoculants (CFo), cassava flour with inoculants (CFi). Substrates were fortified by microminerals contained of Cu (100 ppm), Mn (100 ppm), Zn (100 ppm), I (10 ppm), Fe (2.5 ppm) and Co (2 ppm). Inoculation of S. cerevisiae could reduce fungal contamination. Physical characteristic of cassava flour was better in flavour and texture than rice bran in which tends to rancidity. Nutrients composition was similar in cassava and rice bran however crude fibre content in rice bran tends to be higher after fermentation. Mineral content (Zn and Fe) relatively decreased and in substrate supplemented by inoculant and rice bran had higher than cassava. In summary, micromineral was incorporated in cassava flour with inoculated S. cerevisiae had better than rice bran.Keywords: Organic mineral, cassava flour meal, S. cerevisiae, rice bran, ruminant.

Physical And Chemical

Mustard oil extracted from seasonal crops, Brassica nigra, Brassica junea and Brassica hirta, has enormous edible and non-edible uses in India. The oil is consumed after extraction from mustard seeds, generally without any further processing. High price and dark colour of the oil make it vulnerable for adulteration. But there are some distinct physical and chemical parameters like refractive index, saponification value, iodine value, colour, essential content and unsap composition, by which the purity check of mustard oil can be done. Similarly, acid value, free fatty acid content, peroxide value, p-anisidine value of the oil helps to determine its conformity as safe and standard edible oil. In the present study few samples of mustard oil were procured from local market and analysed them to ascertain their purity and safety parameters. The packed samples are found as un-adulterated but few samples slightly deviated from safety standards.

The objective of this study was to evaluate the viability of using microwave-roasted rice bran as an ingredient in high-fiber cereal bars to obtain a product with good acceptability. The influence of the rice flakes, corn flakes, and roasted rice bran levels on the physical and chemical characteristics of the cereal bars was studied. The overall acceptability of three selected formulations was also evaluated. An increase in the roasted rice bran level in the formulation reduced the force of rupture and water activity, resulted in intermediate density, and caused darkening of the bars. The contents of lipid and total dietary fiber were higher in the formulation with the highest rice bran content, which was therefore classified as functional food. The formulation containing 0.34; 0.32; and 0.34 roasted rice bran, rice flakes, and corn flakes, respectively, seemed to be the best outcome. Cereal bars with roasted rice bran levels between 10 and 20% were accepted by consumers.

And Chemical Properties

In order to reduce the need of petroleum fuels, the prospect of finding the alternative fuel is a primary goal. This work deals with the cause of mustard oil as a possible alternative. The physical and chemical properties of mustard oil are investigated. Using the gas chromatography, the composition of mustard oil is checked. Transesterification process is used for converting the mustard oil into biodiesel. Biodiesel thus formed is converted into bio fuel by the addition of an oxygenated additive (methanol). The current experiment is performed by varying the compression ratio by 16, 17 and 18 using bio fuel which comprises of 80% of mustard oil biodiesel and 20% of methanol in the diesel engine. Emission aspects of bio fuel are investigated. From this experiment it is observed that, by increasing the compression ratio CO and smoke emissions were slightly reduced, whereas HC emission is significantly reduced. However, the emissions of NOx were found to be on higher side.

Experimental data of Ca-induced activated sludge flocculation under different conditions of temperature and dissolved oxygen are investigated in order to model the influence of changing physical and chemical factors. However, current kernel structures for collision frequency and efficiency are unable to describe activated sludge flocculation data. Therefore, an earlier developed methodology based on an inverse problem is applied, yielding empirical models, to find out how flocculation is affected by these different environmental conditions. This contribution shows the useful application of inverse problems to improve the understanding of complex aggregation mechanisms.

The present study was done to evaluate the quality and the vitamin A fortification status of 5 types of commercial edible oils sold in Dhaka city markets. The percentages of free fatty acid (FFA), peroxide value (POV), iodine value (IV) and fatty acid composition were estimated to evaluate the quality and vitamin A content were determined to evaluate the vitamin A fortification status of 25 commercial edible oils- soybean oil, sunflower oil, rice bran oil, mustard oil and palm olein (5 brands of each) . The results revealed that FFA, POV and IV of the commercial oils analyzed were within the BSTI standard limits. The highest saturated fatty acids (SFA) values ranging from 39.85 ± 0.005 to 46.97 ± 0.002 % was found in palm olein samples and the lowest SFA values ranging from 4.56 ± 0.031 to 6.97 ± 0.096 % was found in mustard oils. On the other hand, mustard oils contained highest monounsaturated fatty acids (MUFA) ranging from 69.30 ± 0.189 to 75.87 ± 0.069 % compared to other oils analyzed. Highest polyunsaturated fatty acids (PUFA) were recorded in sunflower oils 64.78 ± 0.035% followed by soybean oils 63.25 ± 0.245%. In addition, except sunflower and mustard oils, vitamin A was found in all the soybean and rice bran oils analyzed. On the contrary, vitamin A was found only in 60% of the palm olein samples analyzed and the content was much lower than the standard value (15-30 ppm). Bangladesh J. Sci. Ind. Res.54(1), 11-20, 2019

An experiment has been conducted under AICRP on Soil Test Crop Response (STCR) at the Central Research Farm (Gayeshpur), Bidhan Chandra Krishi Viswavidyalaya, West Bengal to find out the effect of integrated nutrient management in ArkaHarit variety of bitter gourd. The treatments contain different organic and inorganic fertilizer viz. Control (T1), NPK @ 90:60:60 kg/ha (T2), Vermicompost @ 12t/ha (T3), NPK+ Vermicompost @ 3t/ha (T4), FYM @ 25t/ha (T5), NPK+FYM @ 6.25t/ha (T6), Mustard oil cake (MOC) @ 7t/ha (T7), NPK+MOC @ 1.75t/ha (T8). Application of organic and inorganic sources in an integrated manner has resulted higher in yield, physical and chemical parameter such as seed yield (2815 kg/ha), aggregate ratio (0.69), mean weight diameter (0.593 mm), geometric mean weight diameter (0.679 mm), organic carbon (1.28 %), CEC (12.88 meq/100g), available nitrogen (208 kg/ha), phosphorus (62 kg/ha), potassium (167 kg/ha) in higher magnitude as compare to the single application of inorganic fertilizer. In maximum cases, the chemical parameters is highest in harvesting stage rather than other stage. Quality characters such as Vitamin A, C, crude fibre are nourished in favourable way due to integrated appli-cation of organic and inorganic fertilizers. Based on the performance, it was found that treatment combination of NPK+MOC @ 1.75t/ha (T8) was best among all treatments in most cases for yield, productivity and nutritional as-pects of ArkaHarit variety of bitter gourd.
