ジャーナル フリーA. We studied the preparation of edible fish paste from fish meal by means of mould (Aspergillus oryzae).
Our process is as follows.
1. Fish meal was softened and swelled by boiling with ca. 1% NH4OH solution. By this treatment the rough and sand-like touch of fish meal is removed. (Tab. 1, 2)
2. Starch is added to the softened, swelled fish meal and mouled using Aspergillus oryzae. Moulded fish meal is mixed with NaCl and water. And then mixture is fermented for 10-20 days at 30-35°C.
Softening and swelling process of fish meal was effective to accelerate the enzymic digestion of fish meal during the moulding process.
B. We studied also on the changes of fish meal caused by moulding process. Results obtained are as follows.
1. Decrease of crude protein was slight. (Vab. 4, 7.)
2. Monoamino-N was decreased and cystine was decreased extremely. (Tab. 7, 8.)
3. Decrease of crude fat was very much but that of unsaponifiable matter was not remarkable. (Tab 4, 5, 6, 10.)
4. The production of ergosterol in moulded fish meal was observed. (Tab. 11, Fig. 1.8.)抄録全体を表示PDF形式でダウンロード (588K) -

ジャーナル フリーIt has been reported that the discharge of sexual products of scallop or abalone were artificially induced by simultaneous increase of temperature and alkalinity. In my experiments it was successful to make discharge the mature sexual products of Mytilus edulis by mere bathing its mantle piece in ammoniacal sea water of 0.008 normality (Table 1). In 1-1.5 hours after the mantle was bathed in ammoniacal sea water, it began to discharge the sexual products. However, it was not necessary to immerse the mantle in alkaline sea water until it begins to discharge, but this treatment was enough to induce this reaction for shorter than 1 hour (Fig. 1).
Sea water alkalified by NaOH or by KOH could not make discharge the sexual products from the mantle piece even in 0.02 N solution. M/2 NaHCO3 aqueous solution was also ineffective to induce the discharge. However a pronounced discharge was observed in M/2 NH4Cl solution, which showed somewhat acidic reaction.抄録全体を表示PDF形式でダウンロード (275K) -
HexamethylenetetramineとFormaldehydeの殺菌並に静菌作用に就て山田 金次郎1951 年 17 巻 6 号 p. 161-167

ジャーナル フリーEarlier works on the antibacterial action of preservatives were chiefly concerned with studying the variation in toxicity from one member of a homologous series to the next and there was scarcely anything on the mode of the action.
Accordingly, the writer intend to report in this paper some observations which throw light on the mechanism of antibacterial action of hexamethylenetetramine and formaldehyde.
The results obtained are as follows;
(1). The bactericidal and bacteriostatic actions of hexamethylenetetramine are attributed to the free formaldehyde in its solution (Table 1, 2 and Fig. 3).
(2). The bacteriostatic efficiency of formaldehyde is not markedly increased by increases of hydrogen-ion concentration (Fig. 4).
(3). The inhibitory effect of formaldehyde on the growth of Escherichia coli is repressed by cysteine (Fig. 7).抄録全体を表示PDF形式でダウンロード (428K) -

ジャーナル フリーA collaborative experiment was made on the grinding and mixing machine, wherein the authors took over a portion of the analysis of the mixing power. For the judgement of the proceeding of mixing, the variation of distribution of salt was pursued, which was added to the chopped meat of shark in amount of ca. 3% of the latter at the onset of mixing and grinding. The samples of meat were taken from 5 or 9 definite stations within the mill, 7 times at equal intervals during the whole procedure, being analysed for their salt contents, the data of which were subjected to the critical consideration, (Table 3).
Upon the comparative studies with 2 representative types of this machine in Japanese market, type Y proved itself to be more effective than type A in its mixing power. On the other hand the latter was found to be more effective in that, of grinding, as the other colla borators reported on the basis of histological observations. It was shown, however, that both types can be used satisfactorily for the practical purpose in “Kamaboko” (a sort of fish paste product) industry.抄録全体を表示PDF形式でダウンロード (382K) -

ジャーナル フリーThere are a number of substances which promote polymerization when added to unsaturated oils. These substances are effective in small amounts, and appear to act catalytically.
We studied the nutrutive values of polymerized sardine oils manufactured by the two different catalytic agents, e. g. Japanese acid cly (Sansei-Hakudo) and AlCl3. And as we showed in Table 3, the nutritive value of polymerized sardine oil (Japanese acid cly as caalyst) is better than that of oil manufactured by AlCl3, and moreover polymerized oil No. IV (see Table 2) appeared to be better than soy-bean oil.抄録全体を表示PDF形式でダウンロード (212K) -

ジャーナル フリーComparing the drying efficiency of infra-red ray with that of heated air, we found that the fish products were more speedily dried up by the former than by the latter.抄録全体を表示PDF形式でダウンロード (177K)
