The oxidative stability of palm oil with moisture addition during heationg was investigated and the antioxidant effects of tocopherol, citric acid and sodium polyphosphate were evaluated. The addition of natural tocopherol up to 200 ppm level did not improve the oxidative stability of palm oil with moisture (1m1 $H_2O$ additive to 200g of oil at $180^{\circ}C$). The maximum antioxidant effect was observed at the Concentration of 400 ppm. Addition of citirc acid did not influence the effective concentration of tocopherol. Whereas addition of sodium polyphosphate and citric acid increased the antioxidant effect of tocopherol. The maximum synergistice effect was observed at the concentrations of 50 ppm citric acid and 50 ppm of sodium polyphosphate. Addition of 50 ppm citric acid and 50 ppm sodium polyphosphate to 100 ppm of tocopherol exceeded the antioxidant effect of 400 ppm tocopherol alone.

재동결 명태육의 냉동변성에 미치는 축합인산염처리의 영향을 밝히고져 북양산 냉동명태를 해동하여 fillet로 만든 후 sodium polyphosphate 및 sodium polyphosphate: sodium pyrophosphate(1:1, w/w) 용액에 농도별, 시간별로 침지처리하여 동결저장한 후 해동하였을 때의 육중에 흡수된 인산염량, free drip, expressible drip, drip중의 total solid, total nitrogen 및 DNA함량, 해동시의 fillet의 관능적품질 및 가열조리시 중량감소 등을 실험하여 육질변성의 정도를 비교 검토하였다. 1. 해결전 처리에 의한 육중의 인산염흡수량은 침지시간보다 처리액농도에 더욱 많은 영향을 받았으며, 본 실험 조건하의 전처리육의 인산염함량은 모두 FAO/WHO의 허용기준량이하였다. 2 Drip의 발생량은 육중의 인산염량와 역상관계를 나타 내었고 drip감소에 가장 효과적인 처리조건은 $10\%$, sodium polyphosphate액에 5분간 침지한 것으로 무처리때의 drip 량의 약 $14\%$ 였다. 3. Drip중의 total solid, total nitrogen 및 DNA 함량은 대체적으로 drip량에 비례하는 결과를 나타내었으며, 특히 DNA 감소에 미치는 축합인산염처리의 효과는 컸다. 4. 해동한 fillet의 관능적품질은 고농도처리액에 처리한 것은 광택이 있고, 육질은 강성이 있어 양호하였으나, 저농도액에 처리한 것 및 무처리의 것은 광택과 강성이 좋지 못 하였다. 5. 가열조리시의 감량은 고농도처리액에 장시간 처리한 것은 감량제어의 효과가 다소 있는 듯하였으나, 저농도액에 처리한 것을 그 효과를 인정할 수 없었다.

Elastomer-filler interaction in terms of characterization of filler effects was studied using natural rubber(NR) loaded with kaolin fillers modified with sodium polyphosphate and poly(maleic anhydride), respectively. Kaolins modified with sodium polyphosphate or poly(maleic anhydride) show adhering characteristics by Kraus plot. Reinforcement activity according to Cunneen-Russell method is given by those fillers, in which sodium polyphosphate-treated kaolin presents more favorable results than that treated with poly(maleic anhydride) with respect to adhesion constant, reinforcement extent, elastic constant, and crosslink density. When applied to Blanchard's linkage reinforcement theory, NR vulcanizates loaded with kaolin modified with sodium polyphosphate meet the requirements for both approximate linkage reinforcement(${\psi}'$) of 1.02 to 4.94 and accurate linkage reinforcement($\psi$) of 1.00 to 1.18, representing the values of effective wetting($C_{\psi}$) for 0.001 to 0.029 and intrinsic linkage reinforcement(${\psi}_0$) for 1.015 to 1.124, respectively, whille negligible linkage reinforcement is shown by NR vulcanizates loaded with kaolin treated with poly(maleic anhydride). Dynamic storage modulus(G') given by surface modified kaolins presents more favorable crosslink density rates of $2.260{\times}10^{-5}\;mole/cm^3-min$. for sodium polyphosphate treated kaolin and $1.305{\times}10^{-5}\;mole/cm^3-min$. for poly(maleic anhydride) treated kaolin, respectively, compared to untreated kaolin showing the rate of $1.033{\times}10^{-5}\;mole/cm^3-min$.

라면 제조에 있어서 알카리제의 첨가가 라면의 조직감과 관능적 특성에 미치는 영향을 검토하기 위하여 알카리제의 조성을 달리하여 소맥분에 대하여 0.5%를 사용하여 라면을 제조한 뒤 조리시험, 면의 조직 특성을 측정하고 관능검사를 평가하였다. 알카리제를 첨가하여 제조한 라면의 층밀림 압출력은 시료 A(potassium carbonate 64%, sodium carbonate 14%, sodium pyrophosphate 2% and sodium metaphosphate 20%)가 12.80(kgf)로 가장 높게 나타났으며, 표준 시료 E는 가장 작은 수치인 5.34(kgf)로 측정되었다. 경도도 시료 A가 18.57(kgf)로 가장 높게 나타났으며, 표준 시료 E는 11.23(kgf)으로 측정되었다. 시료 A로 제조한 라면의 무게 증가는 표준 시료 E보다 높게 나타났다. 반면에 부피 증가는 오히려 낮게 나타났으며 시료 A가 가장 낮은 수치를 보였다. 용출양의 차이는 모든 시료가 $35{\sim}38%$의 범위를 나타낸 반면 표준 시료 E는 70%로 나타나 시료 A보다 2배 정도 많게 증가하는 현상을 보였다. 요오드 정색도는 모든 시료가 $2.10{\sim}2.20$으로 유사하게 나타났다. 관능검사 결과는 시료 A와 B(potassium carbonate 31%, sodium carbonate 39%, sodium pyrophosphate 1%, sodium metaphosphate 15%, sodium polyphosphate 8%, sodium phosphate monobasic 4% and sodium phosphate basic 2%)가 각각 4.4, 4.2로 비교적 좋은 점수를 얻었으며, 그 다음이 시료 C(potassium carbonate 60%, sodium carbonate 33% and sodium pyrophosphate 7%)와 D(potasaum carnate 44%, sodium carbonate 27%, sodium metaphosphate 27% and sodium polyphosphate 2%)로 각각 3.8, 3.7을 얻었다. 반면 표준 시료 E는 2.8로 저조한 결과를 얻었다. 이 결과에서 알 수 있듯이 라면 제조시 알카리제의 조성 비율은 시료 A의 조성으로 하여 사용하면 라면의 품질 향상 효과가 크게 나타난다고 할 수 있겠다.

The ameliorative effect of salts and ascorbic acid polyphosphate supplementation on heat stress was studied in buffaloes. Adult buffaloes of either sex were randomly divided into 2 groups of 4 animals each. Group I served as control and Group II was supplemented with sodium bicarbonate, potassium carbonate and ascorbic acid polyphosphate. All the animals were exposed to two conditions of temperature and humidity: hot-dry and hot-humid in a psychrometric chamber for 4 h daily for 10 days. Blood was collected on day 1, 5 and 10 of treatment. The activities of catalase and superoxide dismutase (SOD), concentrations of serum glutathione (GSH), cortisol, sodium, potassium, and chloride and lipid peroxidation were estimated in serum. Lymphocyte proliferation was assessed in blood. The activities of catalase and SOD, serum concentration of GSH, sodium, potassium and chloride decreased while lipid peroxidation and serum cortisol increased in both groups when subjected to heat stress. Dietary supplementation resulted in further decreasing of the enzyme activities but increasing of the serum concentrations of GSH, sodium, potassium and chloride. Lipid peroxidation and serum cortisol increased in the supplemented group in both types of stress. Dietary supplementation caused an increase in lymphoproliferative response to con A. Thus, supplementation of ascorbate in addition to electrolytes relieves the animals of oxidative stress and boosts cell mediated immunity.

Scanning electron microscopy studies were conducted to examine the surface treatment effects of treating agents the proposed in the previous studies on various vulcanizates. Fracture surfaces of the vulcanizates compounded with kaolin treated with sodium polyphosphate of poly(maleic anhydride) presented favorable results as expected from the results of the previous studies. In other words, treating agents such as sodium polyphosphate and poly(maleic anhydride) show considerable reinforcing effects on the vulcanizates.
