Diacylglycerol (DAG) is a novel functional structural lipid, but its application in base oils remains underexplored. This research investigated the effect of three liquid oils (groundnut oil, corn oil, and flaxseed oil), with varying polyunsaturated fatty acid (PUFA) (39.60, 69.50, and 77.65 %) and DAG content (0.00, 40.00, 80.00 %), on the crystallization behaviors of palm-based oil. DAG (40.00 %), obtained through enzymatic glycerolysis and molecular distillation, was found to stabilize the binary system with good compatibility and fine crystal structure. "Liquid" DAG played a dual role: diluting solid lipids, and promoting crystallization. Increasing DAG content led to larger crystalline domain size, while higher PUFA content accelerated crystallization and increased crystal orderliness, though decreasing crystal density. These results demonstrated the clear influence of PUFA and DAG content on palm-based oil crystallization. This knowledge can guide the utilization of different unsaturated DAGs for tailored fat crystallization in food application.

Microencapsulation of oil samples such as flaxseed oil, blended oils such as flaxseed-sesame oil and flaxseed-rice bran oil rich in omega-3 and omega-6 fatty acids was carried out through spray drying technique. During this study, emulsions were prepared and homogenized at 1000 rpm to prepare the stable emulsion. About 8% (w/w) of oils were encapsulated with maltodextrin as wall material and Tween 20 as an emulsifier, yielding a polyunsaturated fatty acid (PUFA) microencapsulated oil powder. The physical properties of powders were calculated based on the bulk density and tapped density observations. Apart from these, Carr's index (C) and Hausner's ratio evaluated to study the flow properties of microencapsulated powders ranged between 30 and 39 for Carr's index and 1.40-1.64 for Hausner ratio, respectively. The results of moisture content stated that oil-encapsulated powders exhibited higher shelf life due to lower moisture content values of 2-4%. Encapsulation efficiency of 73%, 60%, and 80% was achieved for flaxseed oil powder, flaxseed-sesame oil powder, and flaxseed-rice bran oil powder, respectively. Powders high in PUFA such as omega-3 and omega-6 are beneficial for addressing variety of health issues, that can be used most convenient way to receive important nutrients in our period of health issues.

This study aimed to evaluated the effect of dietary fermented pineapple residue (FPR) on the chemical composition, antioxidant capacity, meat quality, fatty acid profile, and volatile compounds in yellow-feathered chickens. GC-IMS technique combined with multivariate analysis were performed to clarify the key volatile compounds. The results showed that dietary FPR improved meat quality by increasing the antioxidant capacity and pH value and decreasing cooking loss of breast muscle. The fatty acid profile was altered in breast muscle of chickens that fed with FPR. GC-IMS detected 43 volatile compounds in breast muscle, including mainly aldehydes, alcohols, esters, and ketones. Among them, 12 volatile compounds could serve as potential aroma markers to distinguish meat flavor of chickens fed with FPR. Correlation analysis revealed that C18:1n9c, C18:2n6, and PUFA are important contributors for meat flavor formation. In conclusion, dietary FPR improved antioxidant capacity, meat quality, fatty acid profile, and volatile compounds of breast muscle in chickens.
