A scanning electron microscope (SEM) was used to study the morphology of starch granules and the strength of market Udon (Japanese noodles), that is, fresh Udon, frozen Udon and cooled Udon after cooking. Udon samples were cooked for a given time and observed with SEM and also we measured the breaking strength. The following results were obtained. 1.The degree of swelling of starch granules in cooked Udon samples differed with the position from the surface. The starch granules near the surface swelled extremely and did not retain their original granular form. 2.A black ring was observed in the cross-section of all cooked Udon in SEM images. The black ring may be caused by the difference in the water content between near the surface and the core of cooked Udon. 3.The starch granules in the core of cooked Udon had a distinct form, but they were not a round shape. The shallow surface layer of each starch granule swelled and gave high contrast. The core of the each starch granule showed low contrast because of its compact structure, which looked black in the SEM images. The area of the black zone was different among Udon samples. 4.There was a correlation between the total area of low contrast zone in the starch granules and the breaking strength of Udon. The area of low contrast zone can be used for an evaluation scale of cooked Udon.

An antitumor antibiotic, ascofuranone, selectively inhibited succinate- and NADPH-dependent O_2 uptake activity of the mito-chondria from Hansenula anomala, suggesting its interaction with the ubiquinone-reduction site of succinate dehydrogenase and external NADPH-dehydrogenase reactions. The action of ascofur-anone on the mitochondria is clearly different from that of antimycin A, the Q_i site inhibitor.

Adult Fischer-344 rats which underwent administration of azoxymethane were fed diets containing soybean curd refuse (SCR) or a high-molecular-weight fraction of soy protein digest (HMF), or Hammarsten casein (CAS) as a protein source over a period of 34 weeks. All the living rats of each group at 22,28 or 34 weeks were endoscopically inspected for tumor incidence in the colon. SCR turned out to be comparable to HMF in anti-tumorigenicity, or rather better than HMF.

An aminopeptidase, Ey, is a newly discovered enzyme of hen's egg yolk. About 95% of the total activity was found in the yolk plasma fraction, with most of the remainder in the yolk granule fraction. The highly purified fraction from plasma showed about 13,000-fold higher specific activities than that of yolk plasma. Polyacrylamide gel electrophoresis revealed that the enzyme was homogeneous. The bound enzyme in the granule was extracted with 3% NaCl and was partially purified. The soluble and bound forms of aminopeptidase differ in solubility, molecular weight, heat stability, optimal pH, and Km.

The apparent viscosity development after onset of steady shear flow was measured at 90℃ for the various samples of mochi cake prepared by a kneading or a stamping method. The typical mochi cake samples showed clear stress overshoot phenomena. The results agreed well with those in a sensory test. This indicates the present nonlinear viscoelastometry is very effective for characterization of mochi cake.

Practical Fischer glycosidation was effected at room temperature or 60℃ by using 5 to 10 equiv. of TMSCl. The anomeric propargyl group formed by this method was found to be a versatile new protecting group, being stable in neat TFA but readily cleaved by treatment with Co_2(CO)_8 and TFA in CH_2Cl_2 via the formation of an alkyne-Co complex.

The use of L-glutamic acid mother liquor as a livestock feed additive was studied. The mother liquor was fermented from hydrolyzed cassava starch, and monosodium glutamate was removed. The mother liquor was then concentrated, which caused dissoluble L-glutamic acid to crystallize, giving a second mother liquor. This mother liquor was concentrated again, and 50% of the minerals dissolved in it were removed. The chemical properties of the remaining mother liquor and the possibility of its use as a livestock feed additive were studied. The lethal dose for 50% of test mice was 36 g/kg of body weight in the test of acute toxicity. Digestible crude protein and total digestible nutrients accounted for 16.8% and 30.4%, respectively. The addition of the mother liquor to ground cassava chips increased the protein concentration, and the most suitable ratio of mother liquor to ground cassava chips for feed intake by cattle was 1 : 3.5. This mix was used to replace 0%, 50%, 75%, or 100% of the maize in feed concentrates for fattening cattle. Feed intake, daily body weight gain, the feed conversion rate, and carcass yiled were greatest in when 50% of the maize was replaced ; protein intake was the same as when no maize was replaced, and the salt intake was low.

The practicality of L-glutamic acid mother liquor for use as a livestock feed additive was studied. At water activity of 0.81, mold did not grow in the feed additive during long-term storage under either aerobic or anaerobic conditions. Results of a subacute toxicity test in rats suggested the safety of the additive. The addition of the mother liquor feed additive to feed for growing swine improved the feed intake, the daily body weight gain, and the feed conversion rate. Digestibility of crude protein, crude fat, and crude fiber was increased when the feed contained a lysine supplement and the mother liquor feed additive. The urinary nitrogen excretion of pigs given a lysine supplement in the feed with the mother liquor feed additive was less than that of pigs not given a lysine supplement with or without the mother liquor. It means that the efficiency of use of proteins in the mother liquor was improved by the addition of lysine.

Bacteria capable of assimilating cellulose acetate, strains SB and SC, were isolated from soil on a medium containing cellulose acetate as a carbon source, and identified as Neisseria sicca. Both strains degraded cellulose acetate membrane filters (degree of substitution, DS, mixture of 2.8 and 2.0) and textiles (DS, 2.34) in a medium containing cellulose acetate (DS, 2.34) or its oligomer, but were not able to degrade these materials in a medium containing cellobiose octaacetate. Biodegradation of cellulose acetate (DS, 1.81 and 2.34) on the basis of biochemical oxygen demand reached 51 and 40% in the culture of N sicca SB and 60 and 45% in the culture of N. sicca SC within 20 days. A decrease in the acetyl content of degraded cellulose acetate films and powder was confirmed by infrared and nuclear magnetic resonance analyses. After 10-day cultivation of N. sicca SB and SC, the number-average molecular weight of residual cellulose acetate decreased by 9 and 5%, respectively. Activities of enzymes that released acetic acid and produced reducing sugars from cellulose acetate were mainly present in the culture supernatant. Reactivity of enzymes for cellulose acetate (DS, 1.81) was higher than that for cellulose acetate (DS, 2.34).

&nbsp;&nbsp;Five microbial strains that removed hydrogen sulfide (H₂S) or methylmercaptan (CH₃SH) gas were newly isolated from soil samples. Strain DO-1, one of the isolates, was identified as a member of <i>Pseudomonas</i> sp., and it&rsquo;s immobilized cells removed 1 or 10 ppm of H₂S gas within 2 hours. When strain DO-1 was cultured aerobically in a flask containing nutrient broth medium, the deodorizing activity increased, depending on the growth of the culture, and the maximum activity was obtained after 48 hours. Even though the immobilized cells were stored at 4 or 25&deg;C in sealed bottles for 6 months, the deodorizing activity remained. Throughout this study, strain DO-1 removed H₂ S gas without preliminary feeding or exposure to sulfur com-pounds as growth substrates or inducers. These characteristics are advantageous for the deodorization of the malodorous gases surrounding us in daily life.<br>

Commercially available egg white was freeze-concentrated using bacterial ice nuclei, which improved its foaming properties. Baked meringue, angel cake, snow-jelly, and marshmallow were prepared using freeze-concentrated egg white foam and their physical properties were evaluated. We concluded that freeze-concentrated egg white can be used to make some foam foods.
