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.

This study investigated the effects of blending alhydwan seed oil and peanut oil as a way of enhancing the stability and chemical characteristics of plant seed oils and to discover more innovative foods of high nutraceutical value which can be used in other food production systems. Alhydwan seed oil and peanut oil blended at proportions of 10:90, 20:80, 30:70, 40:60 and 50:50 (v/v) were evaluated according to their physi­cochemical properties, including refractive index, relative density, saponification value, peroxide value, iodine value, free fatty acids, oxidative stability index, and tocopherol contents using various standard and published methods. At room temperature, all of the oil blends were in the liquid state. The physicochemical profiles of the blended oils showed significant decreases (p < 0.05) in peroxide value (6.97–6.02 meq O2/kg oil), refractive index at 25 °C (1.462–1.446), free fatty acids (2.29–1.71%), and saponification value (186.44–183.77 mg KOH/g), and increases in iodine value and relative density at 25 °C (98.10–102.89 and 0.89–0.91, respectively), especially with an analhydwan seed oil to peanut oil ratio of 10:90. Among the fatty acids, oleic and linoleic acids were most abundant in the 50:50 and 10:90 alhydwan seed oil to peanut oil blends, respectively. Oxidative stability increased as the proportion of alhydwan oil increased. In terms of tocopherol contents (γ, δ, and α), γ-tocopherol had the highest values across all of the blended proportions, followed by δ-tocopherol. The overall acceptability was good for all blends. The incorporation of alhydwan seed oil into peanut oil resulted in inexpensive, high-quality blended oil that may be useful in health food products and pharmaceuticals without compromising sensory characteristics.

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.

Over the last decade, the use of hand sanitizers has increased substantially. Recently, with this outbreak of COVID 19 virus, all natural hand sanitizers have taken the spotlight for their simplicity, powerful cleaning abilities, natural moisturizing formulas and the ability to never leave the skin feeling dry. Marula [Sclerocarya birrea] seed oil was soxhlet extracted with n-hexane and then brominated. The oil quality parameters of marula oil (MO) and brominated Marula oil (BMO) were found to be; for MO: oil content (58.5 ± 0.435 %), moisture content (4.3 ± 0.158 %), saponification value (180 ± 0.7150 mgKOH/g ), peroxide value (10.52 ± 0.006 meq/kg), acid value (3.48 ±0.002) meq/kg ), FFA (1.73 ± 0.000 % as oleic),iodine value (61.02 ± 0.477 gI2/100g ). For brominated marula oil (BMO) ; saponification value ( 168.7 ± 0.930 mgKOH/g ), iodine value ( 8.6 ± 0.490 gI2/100g ), peroxide value (10.63 ± 0.505 meq/kg ), acid value ( 3.42 ± 0.000 meq/kg ), FFA (1.61 ± 0.000 % as oleic). Fourier Transform Infrared (FTIR) spectroscopy was used to confirm the bromination process. The following peaks of absorptions were observed for BMO: C–Br at 600 cm-1 , C–H stretch, (2950 to 2850 cm-1 for alkane), 1750cm-1 for carbonyl stretch, 1450 cm-1 for ester, 1680 cm-1 for alkene. The BMO showed a broad spectrum activity against E. coli, Salmonella sp, Staphylococcus aureus and Streptococcus epidermidis microorganism which gave the inhibitions zones of 19.50 mm, 20.50 mm, 19.00 mm, 18.60 mm respectively. DMSO was used as the negative control while streptomycin as the positive control at 400 mg/ml concentration. Based on these findings, BMO may be use as disinfecting oils or hand sanitizers and will discourage its use as food additive.

The physical value of oil depends upon its chemical composition, even today these values play a vital role while using different oil for industrial products and also, despite the vast nutritional and medicinal significance of egusi melon, there are little details on the shell life and stability of its oil over time. Therefore, the influence of time and temperature on melon seed oil was investigated at temperatures of 0oC and 30oC at different weeks to ascertain its physicochemical value and storage stability. For week zero, at 0oC and ambient temperature (30oC), the result revealed iodine value 124.09, Acid value 3.64 mgNaOH/g, Free Fatty Acid value 1.84 mgNaOH/g, Saponification 217.35 mgKOH/g, Peroxide value 1.25 mg/g oil, pH 5.89 and thiobarbituric acid value 0.1383 respectively. In the 5th week, at 30oC, the result revealed iodine value 91.1543, acid value 12.8921 mgNaOH/g, free fatty acid value 6.4988 mgNaOH/g, Saponification 346.42 mgKOH/g, Peroxide value 9.5mg/g oil, pH 3.2 and thiobarbituric acid value 0.413 respectively. Also at 0oC in the 5th week, the results were observed as follow: Iodine value 102.53, Acid value 7.96 mgNaOH/g, Free Fatty Acid value 4.01 mgNaOH/g, saponification 287.51 mgKOH/g, Peroxide value 6.1 mg/g oil, pH 5.05, and thiobarbituric acid value 0.2658 respectively. Refrigeration (0oC) of oil reduced the rate of most of the oxidative deterioration that produces rancidity. These values are within recommended range for edible oils. These results indicate that egusi melon oil could be a good source of table oil. The statistical results show that there was a significant difference between the melon seed oil stored at 0oC and 30oC (P < 0.001).

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.
