We have investgated UV-Vis absorbance to observe the photoisomerization using the mixture solutions in chloroform and LB monolayers mixed with DLPE and 8A5H containing azobenzene which showed reversible cis-trans photoisomerization irradiated by alternate lights. We have found that the absorbance spectrums of the mixture solutions and LB monolayers were reversibly induced to cis-trans photoisomerization irradiated by alternate lights. In addition, the absorbance of both solution and LB monolayer mixed with 8A5H and DLPE were reversibly by alternate temperatures. As a results, the 1:1(by volume) mixture ratio of 8A5H and DLPE was more flexible and reversible cis-trans photoisomerization than the others.

This research was designed to develop a computer program and evaluate the nutritional balances especially the balance of fatty acids, amino acids and antioxidant vitamins for convenience foods. The Korean convenience food, Kimbab purchased from markets was evaluated by using the self-developed computer program. Contents of calories, protein and calcium were lower(1/3˚＋1/2) than the recommended levels of Korean adult woman, and the carbohydrate/ protein/ fat(CPF) energy ratio was 70: 13: 17. The mean P/ M/ S ratio was 2.2/ 1.4/ 1 and that of Ω6/ Ω3 fatty acids was 17.9/ 1, which was higher than the desirable ratio of 4~8/ 1. Average essential amino acid balance of market-Kimbab samples was within the desirable range even though the absolute amount of protein was lower than the recommended level. Contents of antioxidant vitamins (A, C &E) were lower than recommended levels. Two kinds of nutritionally adjusted Kimbab menu were established by self-developed computer program. Some of major changes was adding food ingredients such as tuna fish and perilla leaf cooked with sesame oil and soybean oil to increase Ω3 series fatty acids. Some fruits and milk were also added to the menu. The adjusted CPF ratios was 63: 15: 22 and the new values for P/ M/ S and Ω6/ Ω3 fatty acids ratios were 1.0/ 1.2/ 1/0 and 6.1/ 1 respectively. In sensory evaluation of two kinds of adjusted Kimbab, the taste and overall estimation scores were higher than unadjusted Kimbab. The computer program developed in this study might be used as a tool for the evaluation of nutritional balance of other convenience foods and menu planning.

Lipid peroxidation is one of the main manifestations of oxidative damage and has been found play an important role in the toxicity and carcinogenesis of many carcinogens. This study was carried out to investigate the effects of aflatoxin B₁ co-administrated with antioxidant vitamins on lipid contents and fatty acids components of liver in mice. For this work, vitamin C and vitamin E, the major antioxidants, were administrated with 10 ㎎/㎏ and 63.8 ㎎/㎏ respectively, through intraperitoneal(i.p) injection to male ICR mice, and 0.4 ㎎/㎏ of the AFB₁ injected by i.p. lhr later. The results were as follows: two fold amounts of free cholesterol, triglyceride, and total cholesterol in serum and liver of mice treated with only AFB₁ were observed, when compared to those of mice co-administrated with antioxidant vitamins. However, the levels of phospholipids in serum and liver of mice treated with only AFB₁ were decreased. Concerning to fatty acids composition of liver from AFB₁-treated mice, P/S ratio was shown more low level in cholesteryl ester, triglyceride, total cholesterol and phospholipid than those of mice co-administrated with antioxidant vitamins. In these data which provide with a reliable evidence on their antioxidantal effects to aflatoxicosis.

The lipid stability of walnut added with water extracts of Ganoderma lucidum, Camellia sinensis and Lycii fructus was studied. The results are as follows : 1. when the extracts were added to walnut, the lipid stability was improved. The antioxidative activities of water extract of Camellia Sinensis and Lycii Fructus were considerably higher than that of Ganoderma lucidum. The antioxidative activity was decreased in the rank order Lycii Fructus$gt;Camellia Sinensis$gt;Ganoderma lucidum. 2. This clearly suggests that water extract of Lycii Fructus at 4℃ Bx level can be used as an alternative natural antioxidant for the lipid stability of walnut.

We carried out this subject to observe photoisomerization using 8A5H and phospholipid(DLPC) containing azobenzene group which has reversible to cis-trans by light irradiation. We investigated the photoisomerization and property of the monolayer film on quartz substrate prepared by the mixture of 8A5H and phospholipid deposited using Langmuir-Blodgett(LB) method. It was found that the absorption spectrum of the 8A5H and phospholipid LB monolayer was induced to photoisomerization by alternate light irradiation. And the absorbance of both the solution of mixtures of 8A5H-phospholipid and LB film was reversibly changed by the acid-base exposure and alternate temperatures.

Several instances of synergistic interaction have been identified between alkyl amine oxide and long chain fatty acohol polyethoxylates in various surfactant formulation. The purpose of this study was examined whether these benefits could be observed within the framework of generic hand-surface cleaning formulations. Comparative evaluation were also carried out to determine the performance characteristics of low-and zero-phosphate systems in which amine oxide and alcohol ethoxylates are used. Best cleaning was observed with 1:1 mixtures of the subject surfactants, but substantial improvements over fatty alcohol ethoxylate alone also were noted with formulations that contained lower ratios of amine oxide
