Tsutomu Yoshida, Junko Edagawa1978 Volume 36 Issue 6 Pages 245-252

JOURNAL FREE ACCESSTwo experiments were conducted utilizing male weanling Wistar rats weighing an average weights of 55g for the first experiment and 80g for the second. Rats were divided into control and experimental groups (6 animals per group) fed 10% casein or isolated soy-protein diets for three weeks.
The effects of two kinds of protein sources were compared on feed intake, body weight gain, feed efficiency, N efficiency, mineral (Ca, Mg, and P) balances for three weeks and bone (femur, and tibia and fibula of the right leg) weights and the content of Ca, Mg, and P in bone at the age of eight weeks.
(1) Body weight gain, feed efficiency, N efficiency and N retention were significantly lower in the isolated soy-protein group than in the casein group.
(2) There was no significant difference in Ca, Mg, P retention between two groups. In Experiment II, there were significant differences in digestibility and retention of Ca, and ratio of P retention between two groups.
(3) Bone weight and Ca, Mg and P in bone were lower in the isolated soy-protein group than in the casein group, especially in Experiment II which showed a significant difference.
(4) It may be considered that nutrient loss and/or increased phytate content in the isolated soyprotein occurred in the process of production.View full abstractDownload PDF (8006K) -

JOURNAL FREE ACCESSThe similarity ratio of food intake pattern has been used as one of the analytical procedures in order to study the diatary life.
This study was designed to show that the method by which the data of family and expenditure survey in Gifu prefecture was computed can be used to evaluate the similarity ratio in food intake pattern.
The matrix of primary data was normalized at both direction of column and row.
The degree of similarity between P and Q regions was determined by the directory cosines estimated by using the normalized vectors. The method of determining the similarity was named “M technique” in this study.View full abstractDownload PDF (6413K) -
Relationship between Protein Intake and Essential Amino Acid IntakeNobuo Matsuno, Miya Nomura, Motoyoshi Miyazaki1978 Volume 36 Issue 6 Pages 261-265
Published: November 25, 1978
Released on J-STAGE: October 29, 2010
JOURNAL FREE ACCESSTo know the effect of the amount of protein intake on the amino acid pattern and chemical score of protein ingested by Japanese people, the essential amino acid intake was calculated from the data of the National Nutrition Survey of the Japanese people conducted in 1974.
The results are shown as follows:
(1) Every essential amino acid intake increased by increasing the protein intake.
(2) In the change of amino acid pattern per gm, protein per day, no significant variation was seen in other amino acids except lysine and aromatic amino acid.
(3) There was a high correlation between the ratio of animal protein to total protein and lysine or aromatic acid content, indicating +0.98 and -0.98, respectively.
(4) The values of chemical scores were not affected by the change of protein intake. And the highest value was Amino Acid Score (100) and the lowest was A/T ratio Chemical Score (61).View full abstractDownload PDF (4852K) -
Reexamination of the Scales of Semantic Differential Method used in Food Preference SurveyJunichi Nakajima, Shuko Yoshikawa, Masayuki Akabane1978 Volume 36 Issue 6 Pages 267-272
Published: November 25, 1978
Released on J-STAGE: October 29, 2010
JOURNAL FREE ACCESSThis study was conducted to survey the preference in the selection of 30 different kinds of foods for 167 Junior college students and their 158 mothers.
The preference of food was estimatd by the scales of a semantic differential method, including 9 scales and 8 steps. Nine scales for the taste evaluation were classified into 5 groups, according to the results based upon the analysis of correlation matrix between scales to find a primary component. This result agreed with one obtained by a cluster analysis.
Furthermore, one of the scales was divided into 6 groups by using multidimensional scales Euclidean norm matrix.
Therefore, it may be concluded that the preference of food can be evaluated by the narrowed dimension of analysis, following the reduced number of scales.View full abstractDownload PDF (6055K) -
Yukie Wada, Yasuo Nakayama1978 Volume 36 Issue 6 Pages 273-278
Published: November 25, 1978
Released on J-STAGE: October 29, 2010
JOURNAL FREE ACCESSThe purpose of this study was to devise an effective method to draw visually a distinctive relationship in the intake pattern of food groups. The intake of food groups was classified in 10 ranks based upon correlation coefficients of the matrix, in which the higher correlation coefficient was illustrated darker. This illustrative method was used to compare the intake of food groups in Kitakusyu City with that of nationwide survey in Japan.View full abstractDownload PDF (5640K) -
