アブラヤシの葉,パーム原油,ファイバー及び空果房の糖脂質を同定定量した。糖脂質の同定には,主にTLCのR<SUB><I>f</I></SUB>値と1-ナフトールや過塩素酸による呈色反応を利用した。定量はデンシトメータで行った。アブラヤシの葉の主な糖脂質はアシルステリルグリコシド,モノガラクトシルジグリセリド,ステリルグリコシド(SG),セレブロシド,ジガラクトシルジグリセリド及びスルホキノボシルジグリセリド(SQDG)であった。一方,パーム原油には,SGとSQDGは存在せず,またファイバーと空果房にはSQDGが存在しなかった。<BR>アブラヤシの葉とパーム原油の各糖脂質の脂肪酸組成についても検討した。飽和脂肪酸ではいずれの糖脂質もパルミチン酸が主であった。不飽和脂肪酸ではアブラヤシの葉ではリノレン酸が多いのに比べ,パーム原油ではオレイン酸が多い点に特徴があった。

Current experimental techniques for estimation of the cell surface tension by contact angle measurements were reviewed. It is shown that in the process of measuring the contact angles of drops of water or air bubbles at biological surfaces, transfer of natural surface active materials to the air/water interface occurs with a consequent reduction in the surface tension. The estimation of cell surface tensions from contact angles based on theoretical calculations in which the air/water tension of pure water is used are in error. The adhering bubble method is preferable for contact angle determinations in biological systems.

The aqueous citric acid solution was added into the vegetable oils (cotton seed oil, soya-been oil) and heated to 180°240°C, and analysed by paper-chromatography with chloroform-acetic acid-water solvent (volume ratio 30 : 15 : 1.2).Authors confirmed that citric acid is decomposed to citraconic anhydride through aconitic and itaconic acids by heating at 180°C for 30min. At 240°C, citric acid was disappeared after 10min heating and only small quantity of citraconic anhydride was detected after 30min heating. No citric acid was detected after 30min heating at the condition of deodorization for oil purification (210°C, 23mmHg, steam blowing).The stabilities were tested by A.O.M. for the oil added with citric acid before and after the deodorization. The A.O.M. stability was higher for the oil added the acid after the deodorization, and when it is added before, it is necessary to restrict the duration time of the deodorization within 30min because citraconic anhydride formed by the decomposition has no antioxidant effect.

Over the last twenty years, some hydrocarbon-utilizing microorgainisms have been found to produce emulsifying materials, namely, biosurfactants. Biosurfactants have certain structural characteristics which are not seen in industrial synthetic surfactants. Application of biosurfactants has been attempted in a wide variety fields, including the tertiary petroleum recovery, pollution-free removing agents, hydrocarbon fermentation, industrial surfactants, and so on. It is explained that a general outline on the current situation of research and development of these biosurfactants, according to the classification depending on the structures of their hydrophilic moieties. And, it is explained that results of our research and development on a sophorolipid, whose derivertive has found commercial utility as a skin moisturizer.

Among the oxidation products of edible fats and oils, lipid hydroperoxides and the low-molecular-weight compounds containing short-chain aldehydes such as 4-hydroxynonenal are absorbed from the intestinal wall and carried into the internal organs with oral administration to rodents. Oral intake of lipid hydroperoxides or the low-molecular-weight compounds causes significant cytotoxic damage to the lymphoid tissues. The DNA synthesis of thymocytes is remarkably depressed and lymphocyte necrosis is observed in the thymus and intestinal Peyer's patches. In these cases, the mitogenic response to concanavalin A of splenocytes is increased. With long-term (90 d) feeding of slightly autoxidized soybean oil (peroxide value ; 150 meq/kg) in mice, the same symptoms as those mentioned above are observed. These findings indicate that oral intake of rancid oils give significant effects on immunocompetent cells and causes depression of the DNA synthesis of thymocytes, which would be one of the major cause for impairing immunocompetent systems in animals.

The solubilities of carbon dioxide in soybean oil, olive oil and linseed oil, and those of nitrogen, hydrogen and oxygen in soybean oil were measured at pressures ranging from 0.2 to about 1 atm. of gases and at temperatures between 30 and 70°C. In most cases, the solubility of gases in oils follows Henry's Law, that is, the solubility of gas increases linearly as the pressure of gas increases. Generally, the solubility of gas in oils decreases as the temperature increases, except for the case of oxygen. The solubility of oxygen at 70°C is as large as about twice compared with that of 30 or 50°C. This might be due to the reason that the oil is oxidized slightly by oxygen at higher temperatures.Another expression of the solubility of gas, the Bunsen's absorption coefficient may be calculated as the Henry's Law rules in every case. These coefficients are shown in Table-2. The temperature dependence of logarithms of the Bunsen's absorption coefficients enables the calculation of the differential heats of solution of gases. These values are listed in Table-3.Although the values of the differential heat of solution of carbon dioxide in fatty oils do not vary so greatly with the kind of fatty oils, it seems that the value depends either on the molar volume or on the iodine value of the fatty oils. The theoretical considerations based on the quasi-lattice model of the solution of gas in oil suggests that the effect of variation of the molar volume of fatty oils on the differential heat of solution of gas is negligibly small, and the effect of the iodine value is predominant.In spite of the low solubility of hydrogen in fatty oil, the differential heat of solution is larger than that of other gases.The viscosities of soybean oil under vaccum or at saturation with gas at a definte pressures were also measured. When carbon dioxide is dissolved in oil, the viscosity, or the flow out time of oil, decreases lineally as the amount of dissolved gas increases. But, when nitrogen is dessolved, the flow time of oil is somewhat longer than that under vaccum, slightly exceeding experimental errors. This might be partly due to the larger differential heat of solution of nitrogen than that of carbon dioxide.

The solidification behavior of cocoa butter from the melt phase was examined during two different types of thermal treatment : simple cooling (60→29°C) and cooling/heating (60→22→30°C).Triacylglycerol composition and polymorphic modified samples were determined. The crystals formed by simple cooling were a mixture of Form V and Form VI of cocoa butter. But only the Form V could be found in crystals obtained by the cooling/heating. These crystals were filtered out and what appeared to be fat blooming of the solidified samples of residual melt was examined. The fat blooming was found in solidified fat after the filtration of simple cooling crystals less than 1 μm in size and in cooling/heating cystals 0.22 μm in size. The addition of 0.2 % of the seed crystals of cocoa butter with Form VI increased the rates of solidification and no fat blooming was observed.

This investigation was carried out to study the effect of some detergents and surfactants on the early stages of growth of radish, chinese cabbage and rice in hydroponic culture.Based on the results and the known highest levels of major anionic surfactants present in river waters, it could be estimated that these are not capable of inhibiting growth of these plants.The threshold level of toxicity on test materials for these plants was different from that of the animals tested.Plants treated with sodium chloride, soybean sauce and phosphorous-containing detergent showed better growth compered to the control.

Acylamino acid is a surfactant comprised of fatty acid and amino acids. There are several natural acylamino acids present as components in living tissuue and the research of acylamino acid started from biological interest. Acylglutamate is the first surfactant utilizing natural amino acid and is being actively sold as mild cleansing product due to its extreame mildness to the skin.Mild and environmentally gentle surfactants are eagerly being sought at present and this has led to increased demand for various acylamino acids.The properties and applications of various acylamino acids are explained and breaf introduction is made for other surfactants derived from amino acids.
