In our endeavor to produce value added Sudanese local products, we have been embarked upon studying our local crops seeds oils. In that respect we have directed our research towards identifying the seed oil fatty acids components revealing their abundance, physio-chemical properties and medical application (Mutasim and Ibrahim, 2016; 2017); Mutasim et al., 2017; 2019; 2020). Here in this note we are pleased to report an astonishing characteristic property of the oil extracted from one of a local crop seeds. It was found that on gentle shaking of the oil with water at room temperature, a stable off white oil/water emulsion is formed (Figure 1). It is then logical on bases of experimental results to envisage and even assume the presence of one type of a natural surfactant among the fatty acids components. To our knowledge, no report on a self-emulsifying oil has ever been reported. We believe that such a finding will have a biological impact since this oil is bioavailable and able to reduce the absorption of its saturated fats components. Whether that natural surfactant is an anionic, cationic or neutral one, it is awaiting our on-going investigation.

Palado (Aglaia sp) is a plant that grows wild in the forest around Mamuju regency of West Sulawesi, Indonesia. This plant is locally known as palado. Palado seeds (Aglaia sp) can be used as a source of vegetable oil because it contains approximately 14.75 % oil, and it has the potential to be used as food ingredients or as raw material for oil production. The purpose of this study was to determine the chemical properties and the composition of fatty acids contained in palado seed oil (Aglaia sp). The employed method involved the use of palado fruit that had been processed to be palado seed and undergoing flouring process. Palado flour was produced by the extraction process by using chloroform solvent with the soxhlet method. The characteristics of the chemical properties in the oil produced were analyzed by using a standard method, including iodine, saponification, and acid values. The analysis of fatty acid composition was conducted by using gas chromatography. The results showed that palado oil extracted with hexane had an iodine value of 15.38 mg/g, saponification value of 190.01 mg KOH/g, and acids value of 1.961 mg KOH/g. The fatty acid composition of the palado seed oil consisted of saturated fatty acids (41.601 %), which included palmitic acid (41.062 %), myristic acid (0.539 %), and unsaturated fatty acids (45.949 %), which included mono-unsaturated fatty acids (MUFA) such as (22.929 %), oleic acid and poly-unsaturated fatty acids (PUFA), which was linoleic acid (23.020 %).

The physico-chemical properties of the extracted oil were studied by the conventional methods. It was observed that Siyal Kanta grown under the soil and climatic condition of Bangladesh contains about 35% of pale yellow coloured oil. The total lipids were fractionated into three major lipid groups, neutral lipids, glycolipid and phospholipids by silicic acid column chromatography. Among the lipids, the neutral lipids were varied from 92.1-92.3%, glycolipid 5.5-5.8% and phospholipid 1.5-1.7% of the total oil of the lipid applied. The oil was also fractionated into mono-, di- and triglyceride by silicic acid column chromatography. The triglycerides were varied from 90.1-90.3%, diglycerides from 2.3-2.8% and monoglycerides from 1.5-1.8%. The saturated and unsaturated fatty acids present in the oil were separated and found to be 14.2-14.5% and 84.2-84.8% respectively depending on the areas in which the plant grows. The fatty acid compositions of the oil were analyzed by Gas Liquid Chromatography (GLC). The major fatty acids found in the oil were oleic acid (23%), linoleic acid (58%), palmetic acid (7%) and ricinoleic acid (10%). Key words: Siyal kanta seed oil; Glyceride; Lipid; Fatty acid.

Study on assessmentof biodiesel fuel potentials of seed crude oil extracts of Balanites aegyptiaaca (L.) Del was carriedout. Standard methods of the Association of Official and Analytical Chemist (AOAC) were adopted to evaluate the proximate, physico-chemical properties and fatty acid  compositions of crude seed oil extracts of the test plant. The proximate constituents of the crude seed oil extract gave crude protein (22.09%), crude fat (56.75%), moisturecontent (1.35%), ash (4.70%), crudefiber (12.75%) and carbohydrate (2.36%). The crude oil physicochemical properties included saponification value(216.439mgKOH/g), peroxide value(4.84meq/kg), acid value(2.18mgKOH/g), iodine value(77.08g/100g), viscosity  value(150.3@30°C) and cetane number(54.08), refractive index(1.487 @30°C), relative density (0.949g/cm3) while calorific value was 39.03(MJ/kg). The fatty acids composition of crude kernel oil extract of B. aegyptiaca indicated the presence of four (4) fatty acids, with relative percentage abundance (RPA) in the order of 67.17% (9,12-Octadecanoic acid (C19 H3402)) > 16.22% (Pentadecanoic acid (C17H3402)) > 11.8kg% (Heptacosanoic acid (C28H5602)) > 4.72% (Oleic acid(C18H3402)). These properties conferred relative prospects on the crude oil of the test plant as a suitable  potential biodiesel substrate and consequently, large scale aforestation efforts be renewed, to guarantee ready availability of the raw materials.

Oil-water emulsion stability was determined for crop origin and refinement of seed oils and their methyl esterified fatty acids (methylated seed oil) as influenced by emulsifiers and herbicides. Oil-in-water emulsion stability of one-refined, degummed, and crude seed oils was affected by the emulsifier. However, emulsion stability of methylated seed oil was not affected by the refinement of the seed oil used to produce the methylated seed oil or by the emulsifier. Oils without emulsifiers or emulsifiers alone added to formulated herbicide-water emulsions reduced emulsion stability depending upon the herbicide and emulsifier. Further, emulsion stability of formulated herbicides plus oil adjuvants was influenced by the oil type, the emulsifier in the oil adjuvant, and the herbicide. Oil-in-water emulsions improved or were not affected by increasing concentration of the emulsifier in the oil. However, T-Mulz-VO at a concentration greater than 10% with soybean oil or 5% with methylated soybean oil reduced emulsion stability with sethoxydim. Emulsion stability of herbicides with adjuvants depends upon the herbicide, the emulsifier, emulsifier concentration, and the crop origin, type, and refinement of oil.

Pumpkin seed oils are rich in bioactive compounds such as tocopherols, sterols, β-carotene, and lutein that have, along with some fatty acids, high nutritional value factors. In addition, it has so far been proven that these compounds have a positive effect on human health. The present study mainly aimed at evaluating the chemical composition and the bioactive compounds of pumpkin (Cucurbita maxima) seed oil of the ‘Béjaoui’ Tunisian cultivar using both cold pressing and solvent extraction methods. The seed oils contained substantial amounts of unsaturated fatty acids, particularly oleic and linoleic acids, with values ranging respectively from 28.19% for cold pressed pumpkin seed oil to 30.56% for pumpkin seed oil extracted by pentane and from 43.86% for pumpkin seed oil extracted by pentane to 46.67% for cold pressed pumpkin seed oil of the total amount of fatty acids. Investigations of different seed oils revealed that extraction techniques had significant effects on the antioxidant activity and the γ-tocopherol. Cold pressed pumpkin seed oil revealed the highest γ-tocopherol content (599.33 mg kg-1) and the highest oxidative stability (3.84 h). However, the chloroform/methanol extracted pumpkin seed oil, which is rich in total phenolics (54.41 mg Gallic Acid Equivalent kg-1), was a more effective scavenger of DPPH radicals (250 µmoles Trolox kg-1) than the poor phenolic pumpkin seed oils extracted by hexane and pentane (110 µmoles Trolox kg-1 vs 100 µmoles Trolox kg-1). Based on its unique seed oil features, cold press extracted pumpkin seed may add great value to product innovation in the industrial, nutritional, cosmetic, and pharmaceutical fields.

Structured Triacylglycerols

Abstract Structured triacylglycerols play an important role in determining the functional properties of fat-based emulsion products. The aim of the study was to evaluate the physical properties of the emulsion systems manufactured on the basis of enzymatically modified rabbit fat with pumpkin seed oil in the presence of sn-1,3 regioselective lipase. Emulsions containing variable contents of thickener and variable fat ratios were analyzed for rheological behavior and particle size changes during storage, and their stability was assessed using the Turbiscan test. The results showed that the emulsion containing the majority of rabbit fat and 1 wt% of carboxymethylcellulose was characterized by the highest stability. On the other hand, the emulsions containing higher amounts of pumpkin seed oil in a fatty base characterized the lowest resistance to destabilization processes. The research confirmed the possibility of producing structured fat which can be the basis for new emulsion systems proposed as a food, cosmetic, and pharmaceutical product.

This study investigates the physico-chemical and fatty acids composition of crude seed oil extracts of Azadirachta indica . The main objective was to evaluate some biodiesel characteristics of the crude seed oil extract of Azadirachta indica. The procedures of the Association of Official and Analytical Chemist (AOAC) were used for assessment of some physical, biochemical, and fatty acids constituents of the test seed oil extract. The physical properties assayed for indicate that the oil is liquid at room temperature, non-drying, with specific gravity, with flash and melting points of 0.910±0.08 g/cm3, 80±2.10°C and 76±1.60°C respectively. The chemical properties included 66.77±2.55 g/100g (iodine value), 1.465±0.07 (refractive index@ 30°C), 212.96±1.16 mgKOH/g (saponification value), 0.39±0.16 meq/Kg (peroxide value), 4.24±0.12 mgKOH/g (acid value), 2.20±0.12 mm2/s (viscosity value), 56.91±2.19 (cetane number), 39.21±1.11 MJ/kg (calorific value) and 2.13±0.05% w/w (free fatty acids). Fatty acids composition of the crude seed oil of A. indica obtained were linoleic, hexadecanoic, octadecanoic and alpha linolenic acids, with retention time and % composition of 18.2 min and 10.8±0.50%, 22.2 min and 30.01±1.79%, 18.2 min and 59.10±2.22%, and 20.2 min and 0.09±0.02% respectively. The crude seed oil extract clearly presents a potential as a biodiesel substrate for incorporation as a proximate blend in auto-engines. This therefore would necessitate intensive afforestation efforts of the plant species for sustainable utilization.
