ジャーナル フリー鮮魚 (アジ) の漁場より消費地までの低温流通過程に保鮮剤として, FFを種々の方法で使用したときの効果および水揚げ時の用水による差違について化学的ならびに官能的な検討を行ない, つぎの結果を得た.
1. 肉部のpH, VBN, TMA-Nの変化は低温流通過程中の鮮度低下が少なかったので処理法による差はみられなかった.
2. 氷蔵後室温に13時間放置し, 人為的に鮮度を低下させた場合にも, 水揚げ時の魚体洗浄方法による差はなかったが, 船上でのFF処理群には化学的判定法で顕著な有効性が認められた.
3. 官能試験では各処理群間に明らかな差が認められたが, FF船上処理群が最もよかった. 水揚げ直後の試料では体表の色つやに良く現われ, 東京輸送試料では, 目, 体表, うろこにさらに顕著な効果がみられた. しかし洗浄方法による差はほとんど認められなかった.
4. FF船上処理群の有効性は東京中央卸売市場での業者による魚価の判定によっても認められた.抄録全体を表示PDF形式でダウンロード (1325K) -

ジャーナル フリーBacteriological survey was conducted 3 times during July and August in 1967, with respect to the contamination of sea water in Nagasaki Port and the sea waters in the holds of fishing boats. To one of the fish hold in each boat was added furyl furamide (FF) for keeping the quality of fishcatch and the others being non-treated control.
In addition, the skins and muscles of horse mackerel samples which had been either treated or non-treated with FF were examined, and the tests were done before and after transport from Nagasaki to Tokyo by rail of rapid service under chilled condition.
Results obtained may be summarized as follows:
1. The sea water in Nagasaki Port being employed for landing such fishcatch as horse mackerel and common mackerel was found to be highly contaminated showing high plate counts and coliform numbers. Moreover, it was noted that Vibrio parahaemolyticus, one of the most important causative organisms of food poisoning in Japan could be detected throughout the present survey.
2. Fairly high bacterial numbers were recorded in the sea water of the control fish holds, while addition of FF at 5ppm to the holds resulted in marked decreases in the number of indicator organisms, and almost no V. parahaemolyticus was detected in the sea water of FF treated fish holds.
3. No V. parahaemolyticus was detected in the fish samples when tested immediately after being landed at Nagasaki, whereas the presence of this organism was confirmed in the control samples of the first experiment. Interestingly, almost no Vibrio was detected in the samples which had been treated with FF.抄録全体を表示PDF形式でダウンロード (1156K) -

ジャーナル フリーThe gas chromatographic behaviours of dulcin were investigated. From the results it became clear that dulcin was decomposed in injection port at higher temperature than about 170°C where it could be vaporised, showing the appearance of the subsidiary peak which was identified to be p-phenetidine. The higher temperature of injection port, the more sharply appeared both peaks, and the subsidiary peak was increased.
By on-column reaction with trifluoroacetic anhydride, the subsidiary peak shifted and the new peak of trifluoroacetophenetidine was observed. In case of the reaction with bis- (trimethylsilyl) -acetamide, the new peak of trimethylsilyl-p-phenetidine and two peaks of trimethylsilylated-dulcin appeared.抄録全体を表示PDF形式でダウンロード (742K) -

ジャーナル フリーIn this report, the determination of dulcin was carried out by after conversion to its derivatives. The results were as follows:
When dulcin was reacted with acetic anhydride-pyridine mixture (1: 4) in boiling water bath for 20 minutes, the product showed a single peak of acetophenetidine gas chromatographically, having a linear relation between the peak heights and amounts of dulcin. In case trifluoroacetic anhydride was added and reacted with dulcin in dichloromethane at room temperature for 5 minutes, trifluoroaceto-p-phenetidine was produced. For the determination of dulcin, the linearity and precision of this method were less than those of the acetylation method, though the procedure was simple and rapid. Dulcin reacted with bis- (trimethyl silyl) -acetamide, and on the gas chromatogram, obtained by using non-polar column, the reaction mixture showed two major peaks which were presumed to be those of mono-and di-trimethyl silyl derivatives of dulcin.抄録全体を表示PDF形式でダウンロード (857K) -

ジャーナル フリーStilbazo was used for the determination of tin in food stuffs, and its analytical result was compared with those obtained by the reference official method.
Presented method was proved to be more suitable for the microanalysis of tin contained in food due to the following reason.
Tin, ranging from 0.1 to 0.8ppm can be determined easily and rapidly without interference by other cations and there are no difficulties in operation, in procedure.抄録全体を表示PDF形式でダウンロード (610K) -

ジャーナル フリーAdministration of ABS to rats during pregnancy caused diarrhea and suppression of body weight gain in groups given 1.0% and 2.0% diet. No remarkable effect was observed in groups given 0.5%, 0.1% and 0.025% diet. Although pregnancy was maintained even in 2.0% group the increase of fetal death and the decrease in fetal development was observed in the group. No macroscopic malformation, assumed to be caused by the administration of ABS, was observed. No deleterious effect on delivery and lactation as well as on development of new-born until 5 weeks after parturition was observed.
Oral administration of aqueous ABS to pregnant mice between 7 and 13 day of pregnancy caused slight effect on maternal weight gain, but no effect was observed in fetus from dams given 24mg/kg ABS. Administration of 240mg/kg caused increase of fetal development suppression and death on 18th day of pregnancy. Occurrence of congenital malformation, assumed to be originated from ABS administration, was not observed.抄録全体を表示PDF形式でダウンロード (1542K) -

ジャーナル フリーFrom the application tests of SMEC medium to the detection of E. coli from various kinds of foods, the following results have been obtained.
(1) In comparison of positive rate of E. coli from oysters applied by SMEC medium with that applied by EC medium, it was revealed that, in SMEC medium, MPN count on the confirmation test was perfectly identical with that on the IMViC completed test, but, in EC medium, the ratio of identity was only 40 percent.
(2) An evaluation of confirmation test was made, applied either by EC- or SMEC-medium for the detection of E. coli as an index of sanitary condition of oysters. Out of 49 EC gas-positive cultures, only 37 revealed to contain E. coli actually. In case of SMEC test, however, all the 37 gas-positive cultures contained E. coli from the market foods was achieved applying EC-, SMEC-, and BGLB-medium.
The results revealed that detection rate of E. coli from the positive specimens through presumptive test was highest in SMEC-medium (79.6%), followed by that in EC-medium (46.3%), while the rate was lowest in BGLB-medium (20.8%).抄録全体を表示PDF形式でダウンロード (1338K) -

ジャーナル フリーDibutyl tin compounds are widely used as the stabilizer of polyvinyl chloride. The determination of such dibutyl tin compounds used can be successfully carried out by square wave polarography using mercuric pool as the electrode. Various kinds of polyvinyl chloride films were manufactured by use of dibutyl tin compounds (chloride, maleate and laurate) as the stabilizer, then the amount of stabilizer eluted by 0.01N hydrochloric acid, 4v/v% acetic acid or 20v/v% ethanol was measured by polarography. From the results it became clear that the organic tin in the stabilizer is more apt to be eluted by ethanol than that in dibutyl tin maleate. The stabilizer was scarcely eluted from rigid polyvinyl chloride in the experimental conditions.抄録全体を表示PDF形式でダウンロード (928K) -

ジャーナル フリーIn this paper a systematic separation of carotene, phytol and chlorophyllin salt from methanol extraction of lyophylized Chlorella vulgaris was investigated and the following results were obtained:
1) Chlorophyllin salt, phytol and carotene were obtained in relatively high yield.
2) Copper and iron chlorophyllin salts from chlorella chlorophyll were conformed to the regulations of food additives.
