This study consists of two parts. The first part is to identify the fatty acid composition of chia seed oils obtained by Soxhlet method using acetone and hexane as extraction solvents with different extraction times including acetone 4 hrs (A4), acetone 8 hrs (A8) and hexane 8 hrs (H8) as a control. Next, the oxidative stability and antioxidant activity of chia seed oils stored at different temperatures (25°C and 40°C) for 18 days were evaluated. From the study, chia seed oil (A8) had the highest content of α-linolenic acid (67.79%) with significant difference (p < 0.05) followed by other oil samples that were extracted using acetone and hexane for 4 hrs (67.54%) and 8 hrs (66.38%), respectively. The oxidative stability of chia seed oil was determined by peroxide value, p-anisidine value and TOTOX value. The results revealed that chia seed oils stored at room temperature (25°C) had higher oxidative stability compared to oil samples stored at 40°C. Elevated temperature strongly affected lipid oxidation. The control sample had higher oxidative stability than acetone-extracted chia seed oils. Meanwhile, antioxidant activity using DPPH (2,2-diphenyl-1-picrylhydrazyl) scavenging activity test was also carried out. Antioxidant activity of chia seed oil extracted by acetone had higher radical scavenging activity inhibition (p < 0.05) than the control sample at both temperatures (25°C and 40° C).The results confirmed that chia seed oil obtained by acetone had higher polyunsaturated fatty acids and lower oxidative stability than hexane. In conclusion, chia seed oil extracted by hexane showed better oxidative stability at different storage temperatures.

AbstractChia seed and flax seed oils are rich in polyunsaturated fatty acids, but are susceptible to oxidative deterioration. The aim of this study was to determine the oxidative stability of chia seed and flax seed oils and enhance the stability using rosemary or garlic extracts. During accelerated storage at 65 °C for 14 days, the antioxidant abilities of rosemary or garlic extracts were evaluated and compared with those of butylated hydroxy toluene, ascorbyl palmitate, and α-tocopherol using peroxide value, conjugated dienoic acids, free fatty acid, thiobarbituric acid value analysis. The profile of volatiles, fatty acid composition, and the tocopherol contents in the treated and/or untreated oils were also determined. Active ingredients of rosemary and garlic extracts were also determined. Rosemary extract was found to provide higher oxidative stability than garlic extract after 14 days in most assays (e.g., the CDA values of 4.8% for rosemary extract and 5.2% for garlic extract in chia seed oil). The contents of γ-tocopherol, linoleic acid, and α-linolenic acid were well retained in the functional oils treated with the two extracts. After accelerated storage, the content of the major odor-active volatiles varied based on the type of oil. Our findings show the potential of natural aromatic plant extracts with respect to improving the oxidative stability of functional oils.

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.
