Objective: Grape seed oil (GSO) from Vitis vinifera L. is a liquid vegetable oil which has been used mainly for its linoleic acid content. However, there are many efforts to convert the liquid form of the oil into a solid form due to the instability under storage condition. The aim of this study was to convert GSO into the solid microcapsules by emulsion crosslinking method with gum arabic as a coating polymer.Methods: The GSO was formulated with gum arabic in the ratios of 1:2, 1:3, 1:4, and 1:5. Gum arabic solution was emulsified with GSO using Span 80 and glutaraldehyde. The emulsion was dropped into a beaker glass of isopropyl alcohol to form microcapsules. The microcapsules were dried at 70 °C. Then, they were characterized in terms of morphology, particle size, swelling index, water content, and entrapment efficiency.Results: The produced microcapsules of GSO showed white yellowish color and spherical shape. The particle size of F1, F2, F3 and F4 microcapsules were 69 μm, 82 μm, 125 μm, and 131 μm, respectively. The water content of the F1–F4 ranged from 4.37±0.34 to 5.70±0.92% and swelling indexes were ranged from 5.54±0.01 to 5.94±0.04. The value of entrapment efficiency of F1, F2, F3, and F4 were 17.33±0.603, 20.73±0.678, 34.22±1.195, and 67.15±2.019%, respectively.Conclusion: The results of this investigation showed that GSO could be converted into the solid spherical microcapsules by emulsion crosslinking method using gum arabic. Taken together, this study has provided the most promising formulation of GSO microcapsules for further production in pharmaceutical industry.

Antioxidant Effects

Wine production is an ancient human activity that generates several by-products, which include some constituents known for their potential in health care and for their role in the food or cosmetic industries. Any variety of grape (Vitis vinifera L.) contains nutrients and bioactive compounds available from their juice or solid parts. Grape seed extract has demonstrated many activities in disease prevention, such as antioxidant effects, which make it a potential source of nutraceuticals. Grape seed is a remarkable winery industry by-product due to the bioactivity of its constituents. Methods for recovery of oil from grape seeds have evolved to improve both the quantity and quality of the yield. Both the lipophilic and hydrophilic chemicals present in the oil of V. vinifera L. make this wine by-product a source of natural nutraceuticals. Food and non-food industries are becoming novel targets of oil obtained from grape seeds given its various properties. This review focuses on the advantages of grape seed oil intake in our diet regarding its chemical composition in industries not related to wine production and the economic and environmental impact of oil production.

The objective of this research is to develop water in grape seed oil nanoemulsions which prepared by low energy method to be used in lipstick base formulation. Water in grape seed oil nanoemulsions were prepared by low energy methods which was employed a Phase Inversion Composition (PIC) technique in elevated temperature at 80°C using mixed-surfactants (tween 20/span 80). In ternary phase diagram (oil:water:mixed-surfactants), the largest area of nanoemulsions was occurred in equal ratio tween 20:span 80 (1:1). The maximum water content of water in grape seed oil nanoemulsions was reached at 20% water with 60% mixed-surfactants (1:1). An unimodal size distribution of water in grape seed oil nanoemulsions with varied water content at 6, 10, and 14% were found with droplet size at 29.33 ± 5.30, 30.23 ± 7.33, and 29.83 ± 11.47 nm. Water content of water in grape seed oil nanoemulsions insignificantly affected to melting profile and hardness properties of lipstick. Water in grape seed oil nanoemulsions which was prepared by low energy can be developed as lipstick base formulation.

Biodiesel Fuels

With incessant increases in fuel prices worldwide and concerns for environmental pollution, the need for alternative sources of energy is becoming urgent. In this study, the potential of grape seed oil for biodiesel as an alternative fuel was evaluated. Refined grape seed oil was bought in liquid form and then subjected to an alkali-catalyzed transesterification process for biodiesel production. The physicochemical properties of the resulting biodiesel—namely, viscosity, cetane number, and heating value—were investigated. The biodiesel was blended with a conventional diesel in various proportions and combusted in a four-cylinder, four-stroke compression ignition (diesel) engine under two loading conditions. Experimental results revealed that the blend ratio of B70 (70% GS biodiesel and 30% conventional diesel) gave the best overall engine performance in terms of maximum power, minimum emissions, and fuel consumption. Furthermore, a novel neural network technique called extreme learning machine was adopted to investigate the optimal blend ratio using the dataset obtained from the experimental results. The results also indicate that the best choice of biodiesel blend ratio is approximately B73.67 (73.67% GS biodiesel and 26.33% conventional diesel). The study shows that grape seed oil could serve as a reliable source of production of quality biodiesel fuels, which could be used as an alternative to conventional diesel fuels.
