The oxidation of squalene was investigated at various conditions. An induction period with a slow increase in hydroperoxide and an accelerated period with a rapid increase are observed. One of decomposition products is confirmed to be a ketone. The formation rate of peroxide derived from a chain reaction model of lipid radical is independent of the peroxide concentration in the induction period, and is expressed by the first order of the peroxide concentration in the accelerated period.

The extraction equilibrium and rate of nickel with 5-dodecylsalicylaldoxime was investigated at 303K. The extraction equilibrium for this system was determined. The dependency of the extraction rate on the concentration of each chemical specie participating in the extraction was examined. In order to analyze the interfacial adsorption mechanism, the interfacial tension between the organic and the aqueous phases either with or without nickel were measured by Wilhelmy's vertical plate method. By analyzing the results based on the interfacial reaction model, it was estimated that the rate-determining step is the interfacial reaction between the adsorbed 1: 1 nickel chelate complex and the extractant. The experimental results obtained the transfer cell can be explained by this interfacial reaction model.

Effect of antioxidants on oxidation of linoleic acid were measured at various reaction conditions. Oxidation was proceeded by the way of induction and accelerated periods and the rate of induction period was suppressed in low addition of a-tocopherol, but in high addition of a-tocopherol, the rate of induction period was promoted and the steady period were observed between the induction and accelerated period. Ascorbic stearate acted as antioxidant of oxidation of linoleic acid. Mutual effect of suppression on the oxidation of linoleic acid was observed in addition of both a-tocopherol and Ascorbic stearate. The rate equation was leaded using the chain reaction model of lipid radical to explain the experimental results.

Biodegradable microcapsules entrapping water soluble materials such as potassium nitrate, bovine serum albumin, and egg yolk proteins were prepared by the solvent evaporation method in a (W/OIW) complex emulsion system. Effects of preparation conditions of (W/O) emulsion and concentrations of salts in the inner and
outer aqueous phases on the capsule morphology and the entrapment efficiency of the core materials were investigated. The entrapment efficiency of core material was improved by decreasing in the volume fraction and concentration of salt in the inner aqueous phase, by the irradiation of ultrasonic wave on (W/O) emulsion, and by increasing in concentration of salt in the outer aqueous phase. The entrapment efficiency decreased by the releasing of core material in the course of wall formation of the microcapsules.

INTRODUCTION
Lipids are oxidized at various conditions. The primary products of oxidation of lipids were hydro-peroxides. The hydro-peroxides are further decomposed with heat and light to form secondary products such as ketones, aldehydes or acids. Considering the harmful effects on health of the hydro-peroxides and these secondary products, it is very important to obtain the information of formation and inhibition of hydro-peroxides. a-Tocopherol has commonly used as an antioxidant of lipids. In this study, the effects of addition of a-tocopherol on oxidation of linoleic acid were investigated for various conditions. -

INTRODUCTION
Reverse micelles have been extensively investigated as a media for extraction of proteins and enzymes2,5,6. Most previous studies were carried out in the system using sodium bis (2-ethylhexyl) sulfosuccinate (AOT) as surfactants. Extraction of proteins with the AOT reverse micellar system can be carried out by the control of the electrostatic interaction, for example, forward extraction can be carried out at pH lower than isoeIectric point (PI) of protein, where proteins have positive charge, and back extraction at pH higher than the pI, where proteins have negative charge. The electrostatic interaction can be most effective for the extraction of protein. However, at the same time, the electrostatic interaction often causes a structural change and inactivation of proteins. Some studies have been reported on the control of the formation of reverse micelles by pH3,4, pressure7 and temperature1 for the purpose of developing novel and effective extraction processes of protein. In this paper, the mixed systems of AOT and long chain alkyl amines, such as tri-n-octylamine (TOA), bis (2-ethylhexyl)amine (DEHA), di-n-octylamine (DOA), n-octylamine (OA) were used as a reverse micellar solution. Effect of pH on the extraction characteristics of proteins and water in the mixed micellar systems was investigated. -

INTRODUCTION
In shochu mash, citric acid, fatty acids and many other minor components are contained in addition to water and ethyl alcohoL Fatty acids react with ethyl alcohol to form their esters having high volatility. and the taste and smell of shochu are influenced by content of these esters [Nishiya et aL, 1978]. Therefore, it is important to determine the esterification rate of the fatty acids and ethyl alcohol in the pot still for the fundamental study of shochu distillation.
In this study. esterification rate of the llinoleic acids and ethyl alcohol, vapor-liquid equilibria of minor ethyl Iinoleate in aqueous ethanol solution, and behavior of ethyl linoleate in batch rectification of aqueous ethanol solution containing linoleic acid and citric acid were investigated. -

Oxidation rates of linoleic acid were investigated under various conditions. Two of the periods, induction having low rate and accelerated having high rate were observed without antioxidant, a-tocopherol. The rate equation of the oxidation was derived by assuming autoxidation mechanism. The rate of these periods were the zero order and the first order of hydro-peroxide formed, respectively. With a-tocopherol, the steady state period was added to both periods without antioxidant. The rate of induction was affected by the amounts of antioxidant. The time length of steady state depended on the dimer of a-tocopheroxyl radical. However, the rate of accelerated period was independent of addition of antioxidant and same order as without antioxidant.

N-Phosphonomethylchitosan(=PHMC) was synthesized to examine the antimicrobial activity against Escherichia coli
(=E'coli) and Staphylococcus aureus(=St.aureus). The antimicrobial activity was evaluated by measuring the decrease in the number of viable cells in the bacteria suspension after contacting with the resin for prescribed time. PHMC exhibited a high antibacterial activity for both bacteria. The antimicrobial mechanism was presumed to be electrostatic interaction between the surface of resin and bacteria. -

The extraction of bovine serum albumin (BSA, M.W. 66 kDa, pI 4.9) was carried out using reverse micelles of sodium di(2-ethylhexyl) sulfosuccinate (AOT). When CaCI2 or MgCI2 is used, BSA is extracted at pH higher than pI. In the cases of KCI and NaCl, the extraction of BSA is occurred at narrow pH range, and the maximum extraction was achieved at pH of 5.5 for NaCl and 5.0 for KCI, respectively. The BSA extraction decreased sharply at high concentration of NaCI and KCI. Sufficient concentration of AOT in the organic phase, which is depend on salt type and concentration, is required to extract BSA to the organic phase. BSA extracted to the organic phase can be backextracted to a new aqueous phase at high pH range and high salt concentration.

Extraction of various proteins into AOT reverse micelles were investigated at various pHs. Large molecular weight proteins higher than 30 kDa, such as ovalbumin, BSA, catalase and hemoglobin, were extracted under a certain condition. Effects of pH and salt on the extraction was dependent on the kinds of protein. In the extraction of large proteins at pH lower than pi, the formation of aggregate of the proteins was predominantly occurred. Large proteins, which formed preferentially the aggregation by the extraction at pH lower than pI, caused structural change in the aqueous phase containing AOT and NaCl by electrostatic interaction.
