Effect of Rice Hull Extract on Lipid Oxidation and Volatiles of Cooked Turkey Meat
남기창,Jeong-Han Kim,AhnDongUk,이승철 한국식품과학회 2004 Food Science and Biotechnology Vol.13 No.3
Turkey breast meat patties containing no additive (control), 0.01% sesamol, 0.1% rice hull extract (RHE), and0.2% RHE were cooked in vacuum bags submerged in a 90oC water bath to 75oC internal temperature, drained, individuallyrepackaged in oxygen-permeable bags, and stored at 4oC. Effects of RHE on lipid oxidation, color, and volatiles in cookedturkey breast were compared with those of sesamol at 0 and 7 days of storage. RHE at 0.1 and 0.2% levels showed significantantioxidant activities. Addition of RHE was effective in reducing production of hexanal and total volatiles. Antioxidant effectof 0.2% RHE was lower than that of 0.01% sesamol. Antioxidant and volatiles-reducing effects of RHE diminished significantlyafter 7 days storage. Cooked turkey breast meat added with 0.2% RHE produced brown color and characteristic RHE odor.RHE contained several phenolic compounds such as o-methoxy cinnamic, 4,7-dihydroxy benzoic, and p-coumaric acidsknown to have antioxidant effects.

The effect of adding 10% fat substitute (10%F) or 2% plum extract (2%P) on the formation of hydrocarbons and 2-alkylcyclobutanones (2-ACBs) in freeze-dried beef patties, irradiated (IR) at 44 kGy, and freeze-dried irradiated cooked beef patties was investigated. Hydrocarbons, such as C_(16:3), C_(16:2), C_(17:2) and C_(17:1), were detected only in irradiated samples and their concentrations were high in the order of 2%P+IR, IR and 10%F+IR. Only irradiated beef samples produced 2-ACBs (2-DCB, 2-TCB, 2-TeCB), and their amounts were high in reverse order. The addition of fat substitute or plum extract did not help in reducing hydrocarbons and 2-ACBs in the freeze-dried irradiated cooked beef. However, the amounts of radiationinduced hydrocarbons and 2-ACBs in all irradiated beef patties even at 44 kGy were too small to be of concern for human consumption.

Dietary Cholesterol Affects Lipid Metabolism in Rabbits
민병록,남기창,Kathleen Mullin,김일석,AhnDongUk 한국식품과학회 2013 Food Science and Biotechnology Vol.22 No.2
Effects of dietary cholesterol [0 (control), 1, 2,4, or 8 g cholesterol/kg diet for 12 weeks] on lipid contents and fatty acid compositions in red blood cell (RBC)membranes and plasma of rabbits and pathological changes and lipid oxidation in their livers were determined. Contents of total lipid and unsaturated fatty acids in RBC membrane and plasma of rabbits fed ≥4 and ≥2 g dosages, respectively,were significantly higher (p<0.05) than those of the control,and their increases were dosage-dependent. Accumulations of neutral lipids in centrolobular regions of livers in rabbits fed ≥2 g were dosage-dependent. Lipid oxidation in liver of rabbits fed 8 g was >2 times higher (p<0.05) than those fed lower dosages. The results indicated that dietary cholesterol can modify lipid metabolisms of rabbits, including biosynthesis and transportation of lipids and fatty acids and incorporation of fatty acid into RBC membranes.

Dosage Response of Atherosclerotic Lesions to Dietary Cholesterol in Rabbits
민병록,남기창,Min Du,Kathleen Mullin,AhnDongUk 한국식품과학회 2013 Food Science and Biotechnology Vol.22 No.5
Thirty New Zealand White rabbits were fed diets containing 0 (control), 1, 2, 4, or 8 g cholesterol/kg diet for 12 weeks to determine the cholesterol dosageresponse of plasma cholesterol and triglycerides, and the development of atherosclerosis. The concentration of plasma cholesterol increased proportionally with the dietary cholesterol dosage during the first 4 weeks, then remained constant until the 12th week. The plasma triglycerides and TBARS concentrations gradually increased with feeding time when rabbits were fed 2 g dosages. Aortas from rabbits fed a 2 g dosage developed moderate to severe multifocal or diffusive atherosclerotic lesions. Aortas from rabbits fed 4 and 8 g dosages were diffusely affected with massive atherosclerotic lesions, and had severe calcification and Alcian blue-positive foci throughout the media of the aorta. These results indicate that at least 2 g of cholesterol/kg in the diet is needed to generate atherosclerotic lesions in rabbit aortas.

Egg yolk lipids: separation, characterization, and utilization
Edirisingha Dewage Nalaka Sandun Abeyrathne,남기창,Xi Huang,AhnDongUk 한국식품과학회 2022 Food Science and Biotechnology Vol.31 No.10
Egg yolk contains very high levels of lipids, which comprise 33% of whole egg yolk. Although triglyceride is the main lipid, egg yolk is the richest source of phospholipids and cholesterol in nature. The egg yolk phospholipids have a unique composition with high levels of phosphatidylcholine followed by phosphatidylethanolamine, sphingomyelin, plasmalogen, and phosphatidylinositol. All the egg yolk lipids are embedded inside the HDL and LDL micelles or granular particles. Egg yolk lipids can be easily extracted using solvents or supercritical extraction methods but their commercial applications of egg yolk lipids are limited. Egg yolk lipids have excellent potential as a food ingredient or cosmeceutical, pharmaceutical, and nutraceutical agents because they have excellent functional and biological characteristics. This review summarizes the current knowledge on egg yolk lipids' extraction methods and functions and discusses their current and future use, which will be important to increase the use and value of the egg.
