JOURNAL FREE ACCESSThe purpose of this study is to find the factors which will be used to assess the palatability of cooked rices from a rheological point of view. To search the rheological characteristics of cooked rice, the load-deformation curves of rices cooked under various conditions were obtained with compressiometer, and for the analysis of these curves, the principal component analysis was applied.
Seven parameters which described the load-deformation curves were reduced to three principal components. The first one was highly correlated to the moisture of cooked rice and regarded as the hardness factor, the second one was related to the state of the surface of cooked rice and regarded as the delicate mouth feeling factor, and the third one was the factor concerning the stickiness.
These principal components will serve as indicators of the palatability of cooked rice.View full abstractDownload PDF (655K) -

JOURNAL FREE ACCESSThe rheological properties of potato starch paste (2.0-4.0 w/v%) were studied as basic research for starch cookery. The samples heated at 80 t and at 98 °C for 2 min were investigated by using a Rotovisco RV3 viscometer. The flow hysteresis curves were classified into three patterns and the thixotropic parameter Th was calculated from the hysteresis loops, respectively. It was obtained that consistency index K, flow behavior index n, the thixotropic coefficient λ and yield stress from the curve of shear stress with time under constant shear rate. The consistency index and yield stress of sample heated at 80°C were much larger than at 98 °C for 2 min, also, these values increased with the concentration. The sample heated at 80 °C pointed out thixotropy (softening for shear) and at 98 °C for 2 min showed negative thixotropy (hardening for shear). While the spinnability parameter was increased in case of higher concentration and heating temperature, there was correlation between flow behavior index n and thixotropic parameter Th.View full abstractDownload PDF (970K) -

JOURNAL FREE ACCESSThe fractionation of Eucheuma serra carrageenan was carried out by employing cetyl pyridinium chloride (CPC), cation fractionating methods and DEAE-cellulose column chromatography. The hot water extract of Eucheuma serra was 62.5 % of dry seaweed, consisted mainly of acidic polysaccharides containing galactose, 3, 6-anhydro-galaotose and sulfate groups. The CPC-complex was fractionated into the κ-type and λ-type by the ion gelling method. A DEAE-cellulose column (acetate form) was used to further fractionate KCl-ppt and KCl-sup. The KCl-sup was eluted with 0.5 M AcONa and 0.1 N NaOH so as to separate two ploysaccharides, since KCl-ppt gave only one peak on this column.
Alkaline sodium borohydride treatment increased the 3, 6-anhydro-galactose level in the KCl-sup and KCl-sup-AcONa fractions, but not that in the KCl-ppt and KCl-sup-NaOH. Also, pretreatment of periodate before alkaline sodium borohydride treatment reduced the 3, 6-anhydrogalactose level in the KCl-AcONa. From these results, it is concluded that the 2, 6-disulfate group was present only in the KCl-sup and KCl-sup-AcONa fractions and that a little amount of 6-sulfate was present only in KCl-sup-AcONa.View full abstractDownload PDF (486K) -

JOURNAL FREE ACCESSThe amount of Zeolite in non-phosphate detergents on cloths has been determined by atomic absorption analysis.
Repeated laundering under home laundry conditions until 30 times, proved that the amount of Zeolite deposited depends upon the surface compactness of the cloths, e.g., 1.4 mg/g in cotton broad cloths.
Though rinsing after the wash reduces the amount of deposition, ultimate quantities of Zeolite remaining on the cloths show nearly constant levels in each different cloths.
Changes of the shape and crystal structure of the Zeolite, which are oscillated for 40 hr in dispersion under various pH conditions and filtered, have been observed through X-ray diffraction pattern and scanning electron micrograph.
It proved that crystal structure of the Zeolite maintained considerably stable in quite a wide range of pH (11.20-6.50).View full abstractDownload PDF (839K) -
Patterns of Sewing Motion by HandsHiroko SAKAMOTO, Junko SANO, Reiko YAMADA1985 Volume 36 Issue 1 Pages 29-34

JOURNAL FREE ACCESSHigh-speed motion pictures gave characteristic curves of sewing motion by both skilled and unskilled students. Patterns cf the sewing motion were classified from the periodicity of the characteristic curve by using Fourier analysis. The correct size of the stitch and the sewing rate could be determined from the motion-patterns of hand sewing.
It would be a new effective approach to training of hand sewing to grasp the patterns of sewing motion by hands.View full abstractDownload PDF (715K) -
Clothes Closets-The Realities and Expectations of HousewivesHiroko ICHIMUNE, Hiroo KAMBAYASHI1985 Volume 36 Issue 1 Pages 35-42

JOURNAL FREE ACCESSWe have made inquiries about the places of family members change their clothes and how to keep them, and also housewives' desire of how to improve the existing conditions for closet spaces. We analyzed the results of our inquiries and foundings as follows :
1) About 30 percent of the subjects change their clothes in other rooms rather than their own bedrooms. They tend to use the living room or spare room for changing their clothes.
2) In many cases they keep their clothes in other rooms rather than their on bedrooms, especially shoes, Japanese native costumes, and off-season clothes. This phenomenon depends on several factors, whether or not they have private rooms, whether or not they have a closet in their own bedrooms, and the size of their bedrooms.
3) Ninety-eight percent of the families put their off-season clothes away and use the closets for seasonal clothes only. But 30 percent of the housewives do not want to do these procedures at every season.
4) At present, clothes are mainly kept in the wardrobe, plastic cases, metal cases and paper boxes, however, many housewives desire the built-in wardrobe for their clothes.View full abstractDownload PDF (1364K) -
