    It was well known that thiamine was readily adsorbed on acid clay and that the adsorbed thiamine was not eluted from the adsorbent. In previous papers, the authors showed the adsorbed thiamine could readily be eluted by some protein or amino acids solution.
    The present experiment was designed to clarify the availability of thiamine adsorbed on acid clay in rats.There was no difference between pure and adsorbed form in growth test. So was it in urinary excretion of both forms.It was concluded that no significant difference was found in the availability of these.

    The nutritional utility of protein of rice and bread was compared by the experiment on five male subjects 23-25 years old.Total experimental period was devided into three, the first period being 5 days as preparation and the second and the third being 10 days each, during which the subjects were fed rice or bread as a staple food each period alternatively. The side dishes were, however, prepared samely throughout the three experimental period containing 19.3 g animal protein per day.
    Results obtained were as follows:
    (1) On the digestibility of the protein, the bread period was superior to the rice period.
    (2) On the nitrogen equilibrium, no difference wes obtained.
    (3) On the ratio of accumulated nitrogen to intake or to absorbed nitrogen, the rice period was superior to the bread period.
    (4) No differences were found between the two periods on the status of blood and physiological functions influenced by working, but on the specific gravity, haemoglobin content of blood and on some physiological functions, better results were obtained from a large number of the subjects during the rice period.

    日常よく用いる野菜類及びキノコ類74種類の総コリン量を硝酸加水分解法によるライネッケ塩法で定量し, 検討を加えた。分析試料中ではキノコ類, 豆類茎葉菜類がコリンに富むが, 特に興味深いのは, アレルギー誘発性食餌とされているクワイ, 里芋, 長芋, タケノコ, キノコ類などの総ゴリン量がいつれも多いこと, 子持カンラン, 花ヤサイのコリン含量が他の野菜にくらべて非常に高いこと, ソラマメのヘソ部に異常に高濃度のコリンが含まれていることなどである.
    また, ペーパークロマトグラフィーを用いて, 植物cho1inereineckateの純度を調べ, 本法で用いた定量法に他物質が殆んど干渉しないことを証明した。

    Riboflavin content of processed albuminous foods that is cheese, dried bonito, pidan, dried mullet roe, and paste of sea urchin eggs, were determined chemically. Free riboflavin and its esters were separated by paper partition chromatography, and their amounts were compared. The author found that the content of riboflavin in those foods was very low except in Chiai (dark muscle) of dried bonito, and that of esteribied riboflavin was small or none. The esters of riboflavin were supposed to shift to free riboflavin in the cource of processing.

    The nutritional effect of the addition of L-lysine and DL-threonine to polished rice was examined in rats fed on polished rice as the single protein source. Examinations were made on the increase of body weight (growth), nitrogen balance, activity of xanthine oxidase in the liver, total protein in the serum, and serum protein fraction. The growth of rats fed on polished rice added with both lysine and threonine was good but liver xanthine oxidase activity was extremely low like the group fed on diet without addition of the amino acids. No significant difference was found in total protein in the serum and serum protein fraction, as well as in nitrogen balance. These observations indicate that the addition of these amino acids alone to polished rice does not give a complete protein nutrition. It was also considered that evaluation of the nutritional value of proteins cannot be made sufficiently by one method but requires examinations by various methods.

    酵母蛋白質の栄養価を検討するため, 酵母が多量のプリン体を含むことから, 酵母蛋白質含有量23%(酵母42%) 及び50%(酵母90%) の飼料を成熟白鼠に与え, 尿中に排泄されるアラントイン態及び尿酸態窒素を定量し, 全卵粉及び一般飼料の場合の値と比較した。
    1) アラントイン態窒素排泄量は夫々摂取窒素量の酵母飼育時6%前後, 一般飼育時2~3%, 全卵粉飼育時1~2%であつた。
    2) 鼠の場合, 体外からのプリンは吸収はされるが体内量蛋白質, 核酸に組み入れられることなく大部分アラソトイソとして尿中に排泄されるといわれており, また供試酵母のプリン態窒素は全窒素の8.23%であることから, 酵母全窒素の6%を生物価0と考え, 第II報の結果より生物価を計算した処, 5%区74.9, 10%区633となり, カゼインより梢よい値を示した。

    牛乳のcurd tensionに及ぼす塩類均衡とくにカゼインに対するカルシウム, 燐の結合状態の影響についてしらべた結は次の通りである。
    1) 牛乳量蛋白質及びカゼイン含量が減少するとcurd tensionも低下する傾向があるが必ずしも一致しない点が認められた。
    2) この原因は牛乳中のカゼインに対するカルシウム, 燐の結合状態の影響であることが認められた。すなわち結合Ca/Pが低くなるとCurd tensionは高くなり硬いcurdを形成するが, curd tensionとの相関性はカゼイン結合Ca/P>カゼイン量>Ca/Pの順に有意的であった。
    3) 牛乳中の蛋白含量が約3.50%を超えるとカゼインの結合カルシウムが減少し反対に結合燐は増加するので結合Ca/Pは顕著に低くなりcurd tensionが急に高くなることが認められた。

    The iodine content of 53 main food-materials in Japan was determined.
    (1) Seaweeds were generally rich in iodine. The highest value of 167 mg% was found indried Laminaria.
    (2) The iodine content of fish and beef liver was relatively high (0.2mg%-O.9mg%), a small amount of iodine was detected in seeds, nuts, pulses, and polished rice (0.04-0.09mg%).

    It is said that Japan is the only non-goiterous conutry. This study is to estimate theiodine intake of Japanese. The daily iodine content in Japanese diets was about 200γ-20mg. The daily urinary excretion of iodine was about 200γ-7mg. Wide individual variationswere due to differences in seaweeds intake. From these results the iodine intake of Japanese is generally estimated to be about 500-1000γ or more daily. This value seemedto be very high than that of any other countries.

    From the standpoint of effect on keeping quality of milk, the comparison was madebetween low pressure polyethylene can and metal can as milk container.
    Several trials of storage tests at room temperature (in summer) and low temperature (3°C) were carried out. Analyses were made on acidity, total bacterial count, vitamin C determination, organoleptic observation, and alcohol test. Samples were collected atintervals of 4 hours for 16 hours in room temperature and 24 hours for 120 hours in lowtemperature test, respectively.
    Data obtained showed that there was no marked difference in effect on keeping qualityof milk between polyethylene can and metal can except for some superiority of theformer in bacterial count and flavor.

    During storage of raw starch, the deterioration of this occurrs and results in the depressions of yield and quality, but any adequate method for this prevention is not yetfound.
    The authors reported already about the purification of potato starch by surface activeagents, and in this paper, the suppressing effect for the deterioration of raw potato starchby surface active agents is observed.
    Raw starch treated with a dilute dodecyl benzene sulfonate solution posseses good stabilityfor deterioration and is kept from the lowering of pH value. By this means, a moreprolonged storage of raw potato starch may be possible Although the suppressing effect for deterioration depends upon the purity of the raw starch, a treatment with 0.05-0.15% of dodecyl benzene sulfonate is generally favorable.
