JOURNAL FREE ACCESSThis study aims 1) to understand the life status of farming couples, focusing on their time use, and 2) to propose to the couples an introduction of the positive life agreement, the contents of which are included in the Family Management Agreement. The survey was conducted in October 1999. The respondents manage farms full-time in Tokyo, Ibaraki, Nagano, Gifu, Gunma, and Kanagawa Prefectures. The results are as follows : First, the gross income of many of our respondents earn more than 10, 000, 000 yen, meaning that their “agricultural work time” as a whole is long. On the other hand, it also creates a circumstance of a shortage of “social/cultural activities time.” Second, there is a clear gender difference in “household work time”. Wives spend longer hours on “household work time” on non-farming days. Thirdly, although they work more than 250 days a year, the farming couples have their own identity as well as life style.View full abstractDownload PDF (2063K) -

JOURNAL FREE ACCESSOne of the concerns about genetically modified foods is that unexpected or unintended proteins or metabolites might result from the genetic modification of crops. We prepared transgenic tobacco and apple shoots as model plants and analyzed the proteins and phenolics to provide fundamental knowledge about the safety of genetically modified foods. An antibiotic-resistant gene was used as a marker for selecting the transgenic plants, and the beta-glucuronidase gene was used to colorimetrically examine the expression of the inserted gene. The proteins and phenolics in the transgenic shoots were compared with those in the non-transgenic shoots. No significant differences were found in the electrophoretic pattern of the proteins, in the protein content, the HPLC profile of the phenolics or in the phenolic content between the non-transgenic and transgenic shoots.View full abstractDownload PDF (1601K) -

JOURNAL FREE ACCESSThe isolation is described of the microorganisms in the traditional fermented 'sour' meat of Southeast Asia, and an investigation is made of the changes in composition of the meat based on a model experiment using these isolated microorganisms. Microorganisms belonging to the Lactobacillus sp. (including Lactobacillus pentosus, Lactobacillus acidophilus and Lactobacillus plantarum), Lactococcus sp., Bacillus sp. and Enterococcus sp. were isolated from the sour meat. An experiment was conducted in which meat (pork) was decomposed by the isolated microorganisms, i.e., Lactobacillus pentosus, Lactobacillus acidophilus and Bacillus amyloliquefaciens. The results show the marked formation of lactic acid and other organic acids. Free acids such as hydrophobic amino acids and branched-chain amino acids were also increased. The decomposition of meat proteins and the formation of proteins of low molecular weight were also observed.View full abstractDownload PDF (1167K) -
-Effect of UV Absorbers on the Photofading of Red Carthamin-Hironori ODA2002 Volume 53 Issue 3 Pages 271-277

JOURNAL FREE ACCESSWhile the contribution of UV absorbers to synthetic dyes has been investigated by several workers, there have been few studies pertaining to the use of functional UV absorbers as a means of improving the light fastness of natural dyes. In this paper, the influence of various UV absorbers on the photofading of carthamin has been examined on cellulose acetate film. The rate of photofading of the color was remarkably suppressed in the presence of UV absorbers bearing nickel sulfonate group, while the addition of simple UV absorbers afforded little retardation in the rate of fading.View full abstractDownload PDF (802K) -

JOURNAL FREE ACCESSFeijoa is mainly cultivated in New Zealand and California, and imported into Japan. The chemical components of feijoa were measured to identify its properties as a food material for possible extended use as an imported fruit. Feijoa contained less moisture and ascorbic acid and more protein, lipid and ash than other tropical fruits. The ratio of reducing sugars to total sugars was about 50%. The main minerals in feijoa were potassium and phosphorus. Feijoa contained more organic acids than other generally cultivated fruits, the main organic acids being citric acid, tartaric acid, propionic acid and succinic acid.View full abstractDownload PDF (598K) -
