To determine the importance of bushel weight as a factor in grading, 51 samples of Sunrise and 34 samples of Mennonite seed were examined for associations between bushel weight and other properties of commercial sunflower seed.Highly significant correlations of bushel weight with total oil content of the seed, r =.867**; percentage kernel, r =.740**; percentage oil in the kernel, r =.795**; and percentage nitrogen in the kernels, r = −.467** were obtained. Oil yield, estimated on the basis of a cake containing 5% oil and 10% moisture, was also associated with bushel weight, r =.871**. The correlation coefficients of bushel weight with iodine value, acid value, and refractive index were not significant.The present grade specifications fail to take full advantage of bushel weight as a factor in grading sunflower seed since the levels were set too low to be effective. It is suggested that the levels might well be 30 lb. for No. 1, 26 lb. for No. 2, and 22 lb. for No. 3 instead of 24 lb. for No. 1 and 21 lb. for No. 2 and No. 3. The effects of this change are discussed in relation to grading of the two varieties and the establishment of appropriate price spreads between grades.** Indicates that the 1% level of significance was attained.

Common Association

Data for oil content, nitrogen, iodine value, 1000-kernel weight, and refractive indices of extracted and expressed oil were determined on three varieties of flax, i.e. Bison, Royal, and Redwing, grown at 35 stations in Saskatchewan. Varietal differences were demonstrated for all properties with the exception of total nitrogen, and significant differences were obtained for all properties due to the effect of environment.Within varieties, highly significant simple correlation coefficients were obtained between iodine value (Hanus) and refractive indices of both expressed and extracted oils. Analysis of residual variance showed that varietal regressions did not differ significantly and prediction equations applicable with equal validity to all three varieties could be derived. Partial correlation coefficients, independent of nitrogen, indicate that these associations are independent of the latter property. A significant association (r =.497**) between oil content and 1000-kernel weight proved to be due to common association of these properties with total nitrogen.A simple intravarietal correlation coefficient of r = −.817** was obtained between nitrogen and oil content. Analysis of residual variance indicated that varietal regressions did not differ in slope and that on the average an increase of 1% in nitrogen was associated with a decrease of 2.45% in oil content. Oil content may be estimated with a standard error of ± 0.57% from the equation, oil content = −2.54 nitrogen + A, where A is a varietal constant.** Indicates that the 1% level of significance was attained.

The physiocochemical properties of Jatropha curcas kernel oils were characterized as potential biodiesel, including oil yield per plant, seed oil content, kernel oil content, acid value, iodine value, saponification value and cetane number. Twenty-five accessions of Jatropha curcas were used for oil content measurement sranging from 21.14 to 40.66 %with a mean value of 32.85% and Kernels oil 48.59 to 60.45 % with a mean value of 56.28 %. The seed index ranged significantly from a seed weight of 45.45 to 64.45 g. Oil yields per plant ranged from 0.44 to 2.85 kg with a mean value of 1.70 kg per plant, respectively. To understand the properties of acid value, iodine value, saponification and cetane number, experimental physio-chemical studies were performed. Since these properties are critical for determining the current oil condition. The current study confirms that accession seeds performed higher than international saponification value, iodine value and cetane number standards may be an important source for meeting potential energy requirements.

Avartana is a unique concept mentioned for Sneha Kalpana. The more the number of Avartana the more potent will be the formulation. “Shata Paka Madhuka Taila" is one such formulation that is explained in Charaka Chikitsa Vataraktha Adhikara. Samples were subjected to pharmaceutico - Analytical study to compare the probable changes that would have happened pharmaceutically & analytically. Shata paka Madhuka Taila was prepared as per reference & samples were Analysed. The change in the organoleptic characters of all the Avartita samples was noted. Consistency of taila to semisolid consistency of ghruta in proceeding Avartana was observed. A slight increase in specific gravity & Refractive index were noted, decrease in acid value & iodine value was observed. Rancidity test passed & peroxide value was nil. slight acidic pH was noted. The presence of more bands with different Rf values was seen towards 50th, 75th & 100th Avartita samples on TLC. Pharmaceutical procedure reveals that concentration of the Active bio constituents of yastimadhu & milk fat gets increased in each Avartana., And it was evident from organoleptic characters like conversion of liquid Consistency of taila to semisolid consistency of ghruta (on cooling) in proceeding Avartana. A slight increase in specific gravity & Refractive index suggests more active constituents, decrease in acid value & iodine value suggests products are more stable & less chance of rancid on successive avartana. Rancidity & peroxide value tells product are not rancid. pH changes indicate slight acidicnature & may be irritant due to high potency. TLC shows the presence of more bands towards 50th, 75th& 100th avarti samples shows more active constituents. Hence Avartana process helps for potentiating the formulation by adding active constituents. Keywords: Sneha Kalpana, Avartana, Shata Paka Madhuka Taila.

This research work was undertaken to evaluate the physicochemical parameters of oil from the cherry kernel non-irradiated and irradiated at 3 and 6 kGy of gamma irradiation for two storage periods (0 and 12 months). The acid value, peroxide value, thiobarbituric acid reactive substances value, iodine value, saponification value refractive index (peroxide value), and the color parameters of cherry kernel oils were determined. The results indicated that the extracted cherry kernel oils were liquid at room temperature with color varying from light yellow to deep red. The physicochemical properties of cherry kernel oils including acid value, peroxide value, thiobarbituric acid reactive substances, iodine value, saponification value, and refractive index values were 1.19 mg KOH g−1, 9.01 meq2 kg−1, 0.014 mg MDA kg−1, 99.48 KOH g−1 I2 100 g−1, 194.50 mg KOH g−1, and 1.472, respectively. Generally, gamma irradiation doses and storage time increased acid value, peroxide value, thiobarbituric acid reactive substances, and refractive index value of cherry kernel oils, whereas no significant (p > 0.05) change due to irradiation was recorded in iodine value, saponification value, and in color parameter (L*, a*, b*, and ΔE values) of cherry kernel oils. However, the properties of cherry kernel oils revealed that the cherry kernel is a good source of oil which could be used for industrial purposes.

Basic fertilization and nitrogen top-dressing of basil was studied in 1984 and 1985 at the Department of Horticulture, University of Helsinki. The total N doses applied were 0, 0.2, 0.4, 0.8, 1.2 and 1.6 kg N/100 m2. In 1984 the plants were of a mixture of different fenotypes and two of those formed 85 % of the crop-stand. In 1985 the variety grown was ’Budakalasz’. The optimum basic fertilization proved to be a compound fertilizer at the rate (NPK) of 0.4—0.16—0.68 kg/100 m2. The content of volatile oils in dried herb ranged from 0.32 to 1.46 %. The total oil content was not significantly affected by fertilization except in 1984 when the fertilization decreased the oil content in the other of those two major fenotypes.

Aims: Evaluate possible application of African Star Apple seed oil as industrial raw material geared towards possible conversion of waste to wealth with no negative impact as it borders on food scarcity. Also unveiling the possibility of a sustainable environment via the eradication of waste from the environment, thereby creating a clean environment. Place and Duration of Study: Fresh ripped fruits of African Star Apple were bought from some local market sellers at Agbarha-Otor market which is located in Ughelli North Local Government Area of Delta State, Nigeria on longitude 6° 2' 54" E /5° 30' 40" N, between November, 2019 and March, 2020. Experimental Details: Soxhlet extraction with n-hexane as solvent was used for the oil extraction of 100 g per batch of extraction. Pretreatment procedure of oil was done prior to transesterification. Homogenous base-catalyzed transesterification reaction was used in this study under controlled experimental conditions such as temperature, reaction time, methanol to oil molar ratio and catalyst type and concentration were examined under varied ranges to ascertain optimum experimental conditions for the reaction. Extracted seeds oil were analysed for its physicochemical properties using standard methods via: specific gravity, acid value, refractive index, saponification value, iodine value and free fatty acid using standard methods. Results: The results showed an oil yield of 14.9%, an indication that the seed reflects a poor source of abundant oil. Results obtained for the physiochemical properties, revealed that; specific gravity, refractive index, saponification value, acid value, free fatty acid and iodine value showed values of 0.896 kg/m3, 1.549, 231.32 mgKOH/g, 3.23 mgKOH/g, 2.07% and 47.63 mg/100 g respectively. Also, results for Methanol: Oil ratio showed that maximum yield was obtained at 6:1 molar ratio. Maximum conversion efficiency for molar concentration was achieved at 0.75% for both catalysts. While a reaction time of 125 min projected better yield. Conclusion: The seed of African star fruit are discarded as waste, therefore its use as a source of oil for industrial feedstock and other domestic application, poses no challenge with regards to food security. Its non-drying potential based on its low iodine value, makes it suitable lubricating oil for industrial application. Similarly, potential application of the oil as feedstock for the production of biodiesel is justified on the basis of its low acid value. Conclusively, the seeds may not have sufficient oil volume potential to be used as edible (domestic) and industrial oil. Consequently upon its low yield, application for biofuel production in commercial scale becomes unrealistic.
