JOURNAL FREE ACCESSPig feces, a malodorous substance, were completely deodorized within 8 hr, using the pig feces deodorized experimentally with a fermentation method by a farmer in Fukuyama city, as a seed culture. Mixture of pig feces and 20% (w/w) seed culture was blended with agricultural wastes such as rice hull, rice straw (cut 5cm long), and saw dust, in order to make 2.5 porosity (liter/kg); without these wastes, the amount of the seed culture was increased to give the same porosity. Then, the mixture was poured and left outdoors in a wooden box with a wire net attached across the bottom to make natural aeration available. During the deodorization process, numbers of actionomycetes and thermophilic bacteria increased; those of other microorganisms including the E. coli group decreased. The actinomycetes group was presumed to deodorize the feces. Hydrogen sulfite and the low-molecular-weight fatty acids, which are the characteristic malodorous agents of pig feces, could scarcely be found in the deodorized feces. Also, methyl-and ethylmercaptan could not be detected in the deodorized feces. By deodorization, the contents of crude protein, fat, and fiber were decreased 36, 41, and 34%, respectively. The deodorized feces can be expected to be a useful manure.View full abstractDownload PDF (1356K) -

JOURNAL FREE ACCESSTwo inosine derivatives were found to be formed when soluble starch and inosine were incubated with the crude preparation of α-glucosidase from rice seeds. One of the derivatives was purified from the incubation mixture by paper chromatography and Sephadex G-15 gel filtration, and obtained in a crystalline form as its hexaacetate. The derivative was identified as 5'-(α-glucosyl) inosine, on the basis of the various experimental results., viz., elemental analyses, UV and NMR absorption spectra, electrophoretic mobilities on paper, and products by hydrolysis with acid and Aspergillus niger α-glucosidase, and oxidation with sodium metaperiodate.View full abstractDownload PDF (479K) -

JOURNAL FREE ACCESSThe effect of concurrent addition (5%) of dietary fiber (DF) from “gobo” (the roots of edible burdock, Arctium lappa L.) was examined in weanling rats fed a low-casein diet containing toxic level of glycine (5%), L-methionine (3%) or L-tyrosine (5%).
Comparative effects of concurrent addition (3%) of various indigestible polysaccharides such as DF from gobo (GDF), konjac mannan (KM, water-soluble), sodium carboxymethylcellulose (CMC), Sephadex G-200, agar-agar and alkali-coagulated edible konnyaku (water-insoluble) and natural or artificial high molecular compounds such as imogolite (one of the clay minerals) and polyethyleneglycol (PEG, degree of polymerization=450) on growth of rats fed a purified diet containing 4% amaranth was also examined.
The following results were obtained: (1) The excessive addition of glycine, methionine or tyrosine to a purified, low-casein diet showed marked retardation of growth. The concurrent addition of GDF did not protect against these amino acid toxicities as judged by growth rate. (2) The growth of weanling rats fed a purified basal diet containing 4% amaranth was markedly retarded and the addition of 3% GDF protected almost completely against amaranth toxicity. (3) A moderate protective effect against amaranth-toxicity was obtained with the following supplements: CMC, Sephadex G-200, alkali-coagulated edible konnyaku and agar-agar. Imogolite and KM had a slight beneficial effect on growth. However, PEG had no protective activity.
These results suggest that DF fulfils its action in the lumen of the gastrointestinal tract because DF had no protective effect against amino acid toxicities which disturb the internal metabolism and that the protective effect is not always associated only with the water-solubility of DF, since CMC and KM were protective against amaranth toxicity as well as GDF or Sephadex G-200.View full abstractDownload PDF (554K) -

JOURNAL FREE ACCESSA combination of head-space technique and FPD gas chromatography was applied to the determination of sulphite in foods.
Alkaline extractant (0.25 N sodium hydroxide) containing potassium-sodium tartrate and ferrous sulphite (antioxidant) was chosen as an excellent extractant of sulphite.
Sulphite was released from the extracted solution in the following way. To 5ml of the extracted solution, 1ml of 60% phosphoric acid was added, the mixure was shaken vigorously, kept for 10min at room temperature. An aliquot of the head space gas thus obtained was injected into a FPD gas chromatograph.
Less than 2μg of sulphite can be assayed without interferences in the presence of any other sulfur compounds.
Recoveries of combined sulphite from dried apricot, dried pineapple, white gourd shavings, horse-raddish powder, onion powder and chopped dried Japanese raddish root were 96_??_104%, respectively.View full abstractDownload PDF (310K) -

JOURNAL FREE ACCESSOn ultrafiltration (UF) of caramel color solution a part of imidazole compounds which are bound with high-molecular-weight coloring matters are retained in the concentrate. These bound imidazoles can be set free by addition of sulfuric acid and can be de-imidazoled by UF.
In this study, OF was done through hollow fiber modules No. IL-100, CL-100 and CL-500 manufactured by Asahi Kasei Kogyo Co. and following results are obtained.
1. The rejection of imidazoles were almost independent of caramel color concentration and operating conditions (recycle rate, pressure and temperature).
2. The rejection of color intensity was not affected by temperature, it decreased with the caramel color concentration and pressure but increased with the recycle rate.
3. Ninety nine percent of total imidazoles could be eliminated from the caramel color solution by observing these steps (a) elimination of permeable imidazoles by UF, (b) adjusting of pH to 2 with sulfuric acid (c) 1, 25 fold concentration UF or 5, 2 fold concentration UF.
4. Total loss of color intensity during complete de-imidazolization by 1, 25 fold concentration UF or 5, 2 fold concentration UF was 10.9% and 6.4% respectively, by using CL-500 module.
5. Ultrafiltered caramel color solution could successfully be concentrated by reverse osmosis without any mentionable color loss and its quality was also improved.View full abstractDownload PDF (531K) -

JOURNAL FREE ACCESSIt was found, by means of gas-chromatographic analysis, that the treatments of rice plant at various stages of growth with lentemin (an active extract of enzymolysis product of Shiitake fungus) resulted in some alteration of fatty acid composition of lipids from rice.
The samples examined were so-called soft-rice (Nanshitsu-mai) harvested at several districts in Japan. The treatments with lentemin brought about a tendency to increase the proportion of oleic acid and to decrease that of linoleic acid in rice lipids, thus leading the lower linoleic acidoleic acid ratio of 0.83±0.08 as compared with 0.89±0.07 for the untreated. The tendency mentioned above appears to be more noticeable on the treatment at the stages of maximum offshoot and/or reduction division than the other stages.View full abstractDownload PDF (203K) -

JOURNAL FREE ACCESSThe compositional and quantitative changes in lipids and fatty acids of triglycerides in cotton seed lipids from 3 to 65 days after flowering were investigated. Component cyclopropene and cyclopropane fatty acids of triglycerides were fractionated on silver nitrate-silicagel column by a modified method of Johnson(12), and the unsaturated fraction products were hydrogenated. This hydrogenated fraction and the original saturated ester fraction were each analyzed by gas-liquid chromatography on 1% Apiezon M on Chromosorb GAWDMCS. The total percentages of cyclopropene and cyclopropane fatty acids in triglycerides were 38.0 and 15.9 mole at 3 and 10 days after flowering, respectively. But these acids showed a marked decrease from 20 days after flowering. On the other hand, linoleic acid rapidly increased with decreasing proportions of cyclopropene and cyclopropane fatty acids from 20 days after flowering.View full abstractDownload PDF (268K) -
