Objective: This study investigated the effects of the administration of ethanolic saffron petal extract (SPE) and vitamin E (Vit E) on growth performance, blood metabolites and anti-oxidant status in Baluchi lambs. Methods: Thirty-two Baluchi male lambs ($35.22{\pm}5.75kg$) were randomly divided into 4 groups. The 1st (control), 2nd (injectable saffron petal extract [ISPE]), and 3rd (Vit E) groups were respectively injected subcutaneously with either physiological saline (5 mL), SPE (25 mg/kg body weight [BW]) or DL-${\alpha}$-tocopheryl acetate (225 IU) once a week. An oral dose of SPE (500 mg/kg BW) was also administered to the 4th group (oral saffron petal extract [OSPE]). Feed intake and BW were measured for 42 days and blood samples were taken on days 1, 14, 28, and 42. The lambs were slaughtered, and tissue samples were taken. Results: Growth performance and many blood metabolites were not affected (p>0.05) by the treatments. Cholesterol of plasma in the ISPE and Vit E groups was similar and less (p<0.01) than both the OSPE and control groups. Although there was no significant difference between the control and other groups for plasma triglyceride, the ISPE group showed lower (p<0.05) triglyceride than the OSPE and Vit E groups. The highest (p<0.01) plasma glutathione peroxidase (GPx) was detected in the OSPE group, while the ISPE and Vit E groups showed higher (p<0.01) superoxide dismutase (SOD) of plasma than the control. Malondialdehyde of plasma in the ISPE group was lower (p<0.05) than the OSPE. No differences (p>0.05) were observed among the groups for antioxidant status of both longissimus dorsi muscle and liver. However, the activity of GPx in the kidney and heart, as well as SOD activity in the kidney, were influenced ($p{\leq}0.01$) by the treatments. Conclusion: Adding ethanolic SPE improved antioxidant status and lowered lipids oxidation in lambs. The SPE and Vit E demonstrated similar effects on antioxidant status in lambs.

This experiment was carried out to investigate the effects of dietary vitamin E levels on carcass characteristics and vitamin E contents, fatty acid composition and lipid oxidation as indicated by thiobarbituric acid reactive substances(TBARS) of the longissimus muscle in Hanwoo steers. Forty Hanwoo steers were randomly assigned to one of four groups and fed the diet containing 200(control), 1000, 2000 or 2500 IU a(alpha)-tocopherol acetate/head/day for 3 months of last finishing period. Backfat thickness was thinner and beef fat color was whiter(P<0.05) in steers fed the vitamin E supplemented diets than those fed the control diet. But the longissimus muscle area and yield grade did not differ among treatments. Marbling score and quality grade were higher(P<0.05) in steers fed the diets containing 1000 and 2000 IU vitamin E than those fed the other diets. Vitamin E concentration in the longissimus muscle was higher(P<0.05) as the vitamin E content in diet was higher. The levels of oleic and linoleic acids in the longissimus muscle were not affected by dietary vitamin E levels. But linolenic and arachidonic acids were lower in steers fed the vitamin E supplemented diets than those fed the control diet. TBARS in the longissimus muscle was not affected by the vitamin E levels in diet until 5th day of storage but delayed muscle lipid oxidation in steers fed the vitamin E supplemented diets after 7th day of storage. Therefore according to this result, it may be concluded that steers have a higher quality grade and higher vitamin E concentration in muscle and lower in TBARS when diet contains 1000 or 2000 IU vitamin E per kg of diet.

Subjective pork quality was determined on the six groups of the following treatments. Meat samples were obtained from pigs which had been fed with finishing pig diets containing 5% beef tallow(C), 3% beef tallow and 2% perillar seed oil(T1), 250ppm vitamin E($\alpha$-tocopheryl acetate) in T1(T2), 3% beef tallow and 2% squid viscera oil(T3), 250ppm vitamin E in T3(T4), 3% beef tallow and 2% CLA(Conjugated linoleic acid, T5). In the fatty acid composition, SFA(Saturated fatty acid) and EFA(Essential fatty acid) were higher in T5 than in the rest of three treatments such as C, T1, T3 groups, while UFA(Unsaturated fatty acid), MUFA(Monounsaturated fatty acid), UFA/SFA, MUFA/SFA were low. The total content of amino acid in the T3 were higher those for the rest of rest of C, T1, T5 the content for vitamin added treatment(T2, T4) groups higher than non treated one. T3 and T5 showed higher TBARS(Thiobarbituric acid reactive substance) values than the C and T1 groups VBN(Volatile basic nitrogen) values were higher in the order of T5>T3>T1>C. There was no difference in total plate counts, number of lactic acid bacteria and number of E. coli. In sensory property, the C and T1 showed a higher acceptance than the T3 and T5. In cooked meats, the T3 showed a lower hardness than that of control(C), T1 and, with a higher acceptance. In TBARS, VBN, total counts, lactic counts, and E. coli counts, sensory test of cooked meat and raw meat, there was no significant difference between vitamin supplement groups within each oil treatment.

In the field of makeup cosmetics, especially, powder-based foundations such as two-way cake, pact and face powder, the quality of which is known to be strongly influenced by the properties of powder, surface treatment technology is widely used as a method to improve the various characteristics of powder texture, wear properties, dispersion ability and so on. The two-way cake or pressed-powder foundation is one of the familiar makeup products in Asian market for deep covering and finishing purpose. In spite of the relent progress in surface modification method such as composition of powders with different characteristics and application of a diversity of coating ingredient (metal soap, amino acid, silicone and fluorine), this product possess a technical difficulty to enhance both of the adhesion power and spreadability on the skin in addition to potential claim of consumer about heavy or thick feeling. This article is covering the preparation and coating method of nano-vesicle that mimic the double-layered lipid lamellar structure existing between the corneocytes of the stratum corneum in the skin for the purpose of improving both of two important physical characteristic of two-way cake, spreadability and adhering force to skin, and obtining better affinity to skin. Nano-vesicle was prepared using the high-pressure emulsifying process of lecithin, pseudo ceramide, butylene glycol and tocopheryl acetate. This nano-sized emulsion was added to powder-dispersed aqueous phase together with bivalent metal salt solution and then the filtering and drying procedure was followed to yield the nano-vesicle coated powder. The amount of nano-vesicle coated on the powder was able to regulated by the concentration of metal salt and this novel powder showed the lower friction coefficient, more uniform condition of application and higher adhesive powder comparing with the alkyl silane treated powder from the test result of spreadability and wear properties using friction meter and air jet method. Two-wav cake containing newly developed coated powder with nano-vesicle showed the similar advantages in the frictional and adhesive characteristics.
