  • Nutritional Status of 74 elderly Koreans(35 men and 39 women) from middle-income households in Incheon were evaluated in terms of dietary nutrient intakes, anthropometric measurements and biochemical blood analysis. The mean consumptions of all nutrients were lower than R.D.A except iron, thiamine and niacin. However, 25.7% of men and 33.3% of women consumed less amount of iron than 75% of R.D.A. Average body mass index of women was sightly but significantly higher than that of men (P<0.05). Obesity rate and triceps skinfold thickness of women were much higher than those of men (23.3% vs 5.4% and 14.9mm vs 9.6mm, respectively). By judging from amounts of hemoglobin, hematocrit, serum iron, total iron binding capacity, mean corpuscular hemoglobin concentration and transferrin saturation of the elderly, 5.6-33.3% of men and 5.0-33.3% of women seem to be possibly anemic.

  • This study was conducted to investigate the noodle added with Pachyrhizus erosus powder. Total contents of carbohydrates, crude protein, crude lipid, ash, and total dietary fiber were 87.14%, 3.14%, 0.81%, 7.82%, and 49.12%, respectively. The water-binding capacity was significantly increased by increasing amount of the Pachyrhizus erosus powder. When the volume of the noodles was measured after cooking, there was no difference between the control and Pachyrhizus erosus powder groups. The texture characteristics of hardness increased by increasing amount of the Pachyrhizus erosus powder. As a result of the sensory test, the 1.5% Pachyrhizus erosus powder noodles showed the highest scores for all items including appearance, flavor, taste, texture and overall acceptability. The bacterial counts of noodle decreased with greater Pachyrhizus erosus powder content on the third days. It is considered that research on antimicrobial activity should proceed in the future. As a result, it was finally suggested that optimum level of the Pachyrhizus erosus powder in the product was 1.5% level.

  • This investigation was undertaken for the purpose of studying the physicochemical properties of rice flour made by various soaking time(1,4,6,8,12 hours) of rice. As the soaking time was longer, the lightness of rice flours increased, on the contrary its redness and yellowness decreased. Rice flours had higher swelling power and solubility by increasing soaking time, but water binding capacity decreased upon soaking of rice. Hot water insoluble amylose of rice flours was decreased, whereas hot water soluble amylose was increased as the soaking time increased. The amylograph indices indicated that initial pasting temperature of rice flours decreased, while maximum viscosity increased as the soaking time increased.

  • Some properties of starch isolated from gamma-irradiated chestnut at doses of $0{\sim}0.45\;kGy$ were investigated. The treatment increased the water-binding capacity and decreased intrinsic viscosity and amlyograph viscosities. Other properties including swelling power and solubility at $80^{\circ}C$, blue value and percent transmittance of starch dispersion were essentially not affected by irradiation at sprout-inhibition dose.

  • The steeping of waxy rice in water at $20^{\circ}C$ for 12 hr resulted in the decrease of protein, crude fat and ash contents. Water-binding capacity and swelling power (at $80^{\circ}C$) of waxy rice flour increased upon steeping. Maximum viscosity of waxy rice flour in 0.19 N sodium hydroxide solution was increased up to 6 hr steeping and decreased thereafter. The amylograph indices increased as the steeping time increased. The degree of changes in properties during steeping was different between two waxy rice cultivars.

  • Separated normal and waxy rice starches were pulverized, and the physicochemical and digestive properties of the starches were determined. The size of both starch granules significantly decreased (less than $8{\mu}m$) after pulverization. For pasting properties, significant decreases of peak and setback viscosity were observed in both of pulverized starches than in native ones. The lower pasting temperature as well as increased solubility and water binding capacity of pulverized starches imply molecular degradation of starch by pulverization. For thermal properties, onset temperature and melting enthalpy significantly decreased after pulverization, especially in normal rice starch, however there was no difference in amylose-lipid complex before andafter pulverization. The slowly digestible and resistant starch portion of normal rice starch increased after pulverization, however, in waxy rice starch, the rapidly digestible portion increased.

  • Capacitated goat spermatozoa generated diacyl glycerol (DAG) when suspended in Krebs-Ringer bicarbonate medium and induced by progesterone or $Ca^{2+}$ ionophore A23187. We have added Sn-1-oleoyl-2-acetyl glycerol externally, to study the effect of DAG in goat sperm acrosomal exocytosis. Addition of neomycin abolished the DAG generating capacity of progesterone in a dose dependent manner, suggesting the involvement of a phosphoinositidase C activated phospholipase C system in the process. The level of increase in phosphatidic acid was considerably low and was produced well after the DAG generation thereby suggesting the involvement of a DAG kinase which phosphorylates DAG to produce PA. The inhibition of progesterone mediated effect by inhibitors of $GABA_A/Cl^{-}$ channel and $Ca^{2+}$ channels further supports the evidence that the events of binding of agonist to the receptor(s), opening of $Ca^{2+}$ channels and the activation of phospholipase C are reconciled to perform the function of acrosome reaction in capacitated goat spermatozoa.

  • Physicohemical properties of corn starches isolated from non-glutinous and corn grains fol-lowing γ-irradiation up to 10kGy were investigated. Blue value, water binding capacity and swelling power decreased, while alkali number ad solubility increased by γ-irradiation , which was more pronounced in glu-tinous corn starch than in non-glutinous corn starch. The optical transmittance increased with an increment of heating temperature and applied irradiation doses. No significant difference was observed in Hunter's color value between both starches isolated from non- irradiated and irradiated and irradiated corn grains. Amylograph viscosities decreased remarkably as dose levels increased. The overall effects of γ-irradiation was more distinguished in glutinous starch than in non-glutinous starch.

  • Octenylscuccinated corn starches prepared by reaction of corn starch with 1-octenylsuccinic anhydride(OSAn) and their degree of substitution (DS), reaction efficiency(RE), residual octenylsuccinic acid (OSA), and physicochemical properties were compared with those of the native corn starch. DS increased with increase of OSAn and RE was much nearly the same regardless of increased of OSAn. The content of residual of residual OSA was significantly lower than that of regulation of food additives. And as washing frequency of dispersion of the reactant was increased, the content of residual OSA of octenylsuccinated starch was decreased. Raid Visco-Analyzer initial pasting temperature and setback of octenylsuccinated starches decreased whereas peak viscosity and breakdown increased. When DS of octenylsuccinated starches increased, temperature of initial gelatinization of octenylscuccinated starches drastically decreased. The octenylsuccinated starches also formed clearer pastes. The solubility was much nearly the same regardless of increase of DS at 7$0^{\circ}C$ but the swelling power increased 1.2~1.7 times higher than that of native corn starch at 7$0^{\circ}C$. The water binding capacity of octenylsuccinated starches also decreased.

  • The effects of addition of brown rice flour on the Backsulgies were examined. We chose the addition ratio of brown rice flour as 0%, 50%, 100% along with the pilot study. The addition of brown rice flour did not make significant changes in water-binding capacity, swelling power and the degree of gelatinization. But the addition of brown rice flour had a delaying effect of retrogradation of Backsulgies by textural analysis. In sensory evaluation, the Backsulgi added brown rice flour 50% had the highest value in the overall quality of sensory characteristics. But there was no significant difference in the other sensory characteristics between the 50% and 0% added with. Therefore we concluded that the addition of brown rice flour on Backsulgies improve the sensory characteristics as well as delay the retrogradation and would be a good source of dietary fiber.
