Chia seed oil-in-water emulsions as potential delivery systems of ω-3 fatty acids

The aim of this study was to evaluate the effect of a 2% chia seed oil addition to natural yogurt on its quality and to determine whether chia seed oil can be used as an additive in fermented milk products. The dominant species of microorganisms found in yogurt was Lb. delbruecki subsp. bulgaricus. The number in natural yogurt varied from 6.2 to 6.3·106 CFU·g-1 and in enriched yogurt between 6.1 and 6.3·106 CFU·g-1. Chia seed oil contained 4.5 g of sterol per 100 g of oil. The addition of 2% chia seed oil to natural yogurt resulted in a high content of phytosterol in yogurt. Natural yogurt contained 1.2 g of cholesterol in 100 g of the fat fraction of yogurt. Enriched yogurt contained 2 g of phytosterols. The addition of 2% chia seed oil to natural yogurt resulted in higher amounts of unsaturated fatty acids, especially linoleic and α-linolenic acid.

Agro Ecological Zones

The chia seed samples were purchased from farmers in five locations in three agro-ecological zones in Kenya. The oil was obtained by cold pressing and physicochemical properties were determined; the fatty acid profile was determined by Gas chromatography. The mean oil yield from pressing was 16%, the refractive index of chia seed oil at 25 °C ranged from 1.4811 to 1.4832, specific gravity ranged from 0.9616 to 0.9629, acidity index and free fatty acids content ranged from 0.0345-0.0808 mg KOH/g oil, and 0.1736-0.4061%, respectively. The matter in volatiles ranged from 0.047-0.086%. The saponification value ranged from 162.1969–183.3791 milligrams (mg) of potassium hydroxide (KOH) per gram (g) of chia seed oil. The differences in refractive index, acidity index, free fatty acids, specific gravity, and saponification value, were statistically significant at (P<0.05). The α-linolenic (C18:3) and linoleic acids (C18:2) were the dominant fatty acids in chia seed oil and they varied with regions. The levels α-linolenic (C18:3) and linoleic acids (C18:2) ranged from 53.32-64.04% and 19.37-22.87%, respectively. The levels of oleic, linoleic, and linolenic fatty acids in chia seed oils from different regions were statistically significant at (P<0.05). The study recommended the cultivation of chia seed in agro-ecological zones II and III where higher yields and higher content of linoleic and linolenic fatty acids were reported, consumption of chia seed oil as edible oil, and substitution of marine oils with chia oil as potential sources of polyunsaturated fatty acids.

Chia Seed Oil

Abstract Alpha-linolenic acid (ALA) and linoleic acid (LA), abundant in chia seed oil, are useful polyunsaturated fatty acids (PUFA) with numerous health benefits. The objectives of the present study were to explore the optimum extraction condition of chia seed oil and the possibilities of direct analysis of ALA and LA in chia seed oil by reversed-phase high-performance liquid chromatography with ultraviolet detection (RP-HPLC-UV). The optimized chia seed oil extraction condition was set by the usage of Soxhlet extrator with hexane as a solvent, with the solvent to solid ratio of 8 and the extraction time of 8 h. Prior to HPLC-UV analysis, the oil was saponified in order to get the free fatty acids for detection. The results showed that the proposed HPLC-UV method allowed the quantification of ALA and LA in chia seed oil. The method was simple, rapid (within 18 min) and sensitive (limit of detection 0.006 mg/mL for ALA and 0.02 mg/mL for LA) and precise (RSD ≤ 2%). Thus, the proposed experimental designs were shown to offer considerable advantages over traditional derivatization approaches in the ALA and LA analyses.

Chia Seed Oil

The purpose of this research was to investigate the chemical profile, nutritional quality, antioxidant and hypolipidemic effects of Mexican chia seed oil (CSO) in vitro. Chemical characterization of CSO indicated the content of α-linolenic acid (63.64% of total fatty acids) to be the highest, followed by linoleic acid (19.84%), and saturated fatty acid (less than 11%). Trilinolenin content (53.44% of total triacylglycerols (TAGs)) was found to be the highest among seven TAGs in CSO. The antioxidant capacity of CSO, evaluated with ABTS•+ and DPPH• methods, showed mild antioxidant capacity when compared with Tocopherol and Catechin. In addition, CSO was found to lower triglyceride (TG) and low-density lipoprotein-cholesterol (LDL-C) levels by 25.8% and 72.9%respectively in a HepG2 lipid accumulation model. As CSO exhibits these chemical and biological characteristics, it is a potential resource of essential fatty acids for human use.

Chia Seed Oil

The use of a new bio-based plasticizer derived from epoxidized chia seed oil (ECO) was applied in a poly(lactic acid) (PLA) matrix. ECO was used due to its high epoxy content (6.7%), which led to an improved chemical interaction with PLA. Melt extrusion was used to plasticize PLA with different ECO content in the 0–10 wt.% range. Mechanical, morphological, and thermal characterization was carried out to evaluate the effect of ECO percentage. Besides, disintegration and migration tests were studied to assess the future application in packaging industry. Ductile properties improve by 700% in elongation at break with 10 wt.% ECO content. Field emission scanning electron microscopy (FESEM) showed a phase separation with ECO content equal or higher than 7.5 wt.%. Thermal stabilization was improved 14 °C as ECO content increased. All plasticized PLA was disintegrated under composting conditions, not observing a delay up to 5 wt.% ECO. Migration tests pointed out a very low migration, less than 0.11 wt.%, which is to interest to the packaging industry.
