| خلاصه مقاله | Abstract Introduction: Plant-derived oils and fats are estimated to constitute at least 79% of the annual global oil production. Flaxseed oil, which is rich in omega-3 fatty acids, has been linked to the prevention and reduction of several serious health conditions, including cancer, diabetes, atherosclerosis, hypertension, eczema, gastrointestinal disorders, and cardiovascular diseases. Despite its numerous health benefits, flaxseed oil is susceptible to oxidation. The process of extracting flaxseed oil from flaxseeds yields 32–45% of the seed mass, with the oil containing 55–57% alpha-linolenic acid (ALA) and 15–18% linolenic acid (n-6). Mixing flaxseed oil with other oils, such as olive and sesame, can create a balanced fatty acid profile while preserving oxidative stability. However, during storage, the peroxide and anisidine values of these oil blends tend to increase. Methods and Materials: Microencapsulation techniques have been developed to enhance its stability and applicability in food products. Results: Flaxseed, packed with alpha-linolenic acid, lignans, and fiber, provides multiple health benefits. Regular intake may enhance lipid metabolism, reduce hypertension, regulate blood sugar, and mitigate insulin resistance. Scientific studies focus on protective processing methods like coating milled flaxseed with Arabic gum, ascorbic acid, and hydrogenated fats to minimize oxidation. Microencapsulation shields oxidation-sensitive compounds in foods, improving stability. Key methods include physical (spray/freeze drying), chemical (interfacial polymerization/cross-linking), and physico-chemical (ionic gelation/coacervation) techniques. Incorporating flaxseed oil into zein films boosts tensile strength and moisture resistance, while maltodextrin with sodium caseinate showed optimal encapsulation performance. These strategies enable effective integration into foods while preserving nutritional potency and absorption. Conclusions: As a result, the food industry can develop functional products that harness the health-promoting properties of flaxseed oil while ensuring product stability and quality. |
