Some Physico-chemical properties of korean red pepper seed oil were evaluated to find available method to utilize red pepper seeds used as useful cooking oil resources. Samples of red pepper seeds used as oil meterials were native, improved species and they were named such as NS (native spicies dried under sunlight), IS (improved spicies dried under sunlight), NF (native spicies dried by heating), and IF(improved spicies dried by heating), respectively. Moisture, ash, crude protein and crude fat contents of all red pepper seeds were 6.6%∼7.7%, 3.3∼3.5%, 18.25∼19.4% and 26.8∼27.5% in all samples, showing the specially high crude fat and crude protein content in NS. Capsaicin contents in crude red pepper seed oils were shown from 0.06 to 0.08% but after refining process, capsaicin contents were mostly tossed as 0∼0.006%. The types of tocopherol found in crude and refined red pepper seed oils were ${\gamma}$-, ${\alpha}$-, $\delta$-analogues, the amount of total tocopherol in IF was 2.10 mg/g oil which were the highest value of all red pepper seeds. In all red pepper seeds oils main fatty acids were linoleic acid (68∼70%), palmitic acid (14∼16%), oleic acid (10∼11%), and linolenic acid were extemely small amounts. The specific gravity (SG) 0.916∼0.919, refractive index (RI) 1.4724, acid value (AV) 0.26∼0.36, peroxide value (POV) 0.73∼1.19 and Iodine value (IV) 134.35∼134.92 were measured in all red pepper seed oils.

A Study was carried out to elucidate the triglyceride compositions of the red pepper seed oils harvested from two different areas. The oil was extracted from the red pepper seed with nhexane. Each triglyceride of the oil was separated by thin layer chromatography (TLC) and fractonated by reverse phase high performance liquid chromatography (HPLC) on the basis of acyl carbon numbers, and partition number group(PN) and fatty acid composition of triglyceride were analyzed by gas liquid chromatography (GLC). From the results, it was found that the red pepper seed oils of the Chungsong and Youngyang areas consisted of 14 and 18 kinds of triglycerides, respectively. The red pepper seed oil of the Chungsong area consisted of (C18:2, C18:2, C18:2=41.0%), (C16:0, C18:2, C18:2=37.1%), and that of the Youngyang area consisted of (C18:2, C18:2, C18:2=41.0%), (C16:0, C18:2, C18:2=36.3%) and (C16:0, C16:2, C18:2=8.4%), as the major triglycerides.

The stability of red pepper seed oils during storage at 20${\pm}$3$^{\circ}C$, 40${\pm}$3$^{\circ}C$ and heating at 140${\pm}$3$^{\circ}C$ or 180${\pm}$3$^{\circ}C$ were measured to evaluate red pepper seed oil as a cooking oil. Two species of red pepper seeds (native, improved) were dried by either sunlight or heating to prepare the oil samples of NS (native, sunlight-dried), IS (improved, sunlight-dried), NF (native, heated), and IF (improved, heated). During storage at 20${\pm}$3$^{\circ}C$ or 40${\pm}$ 3$^{\circ}C$, acid values (AV) of all red pepper seed oils were higher than that of soy bean oil (SBO), however, peroxide values (POV) were similar to SBO. Antioxidative stability of NS was better than SBO but IF was not. By the heat treatments at 140${\pm}$3$^{\circ}C$ or 180${\pm}$3$^{\circ}C$, NS was identified to have better antioxidative stability than SBO and IF was the lowest. In sensory evaluation of each deep-fat fried potato-chip at 180${\pm}$5$^{\circ}C$, potato-chips fried in NS were better than that of SBO for color, taste, and flavor. NS-fried potato-chips got the highest score in overall acceptance (p<0.05), however, those of IF showed little acceptance. When blended oils (SBO: NOS, 0, 25, 50, 75%) were used, 50% blended oil was the best for taste, color, flavor, cripness, and total acceptance.

The role of fat is important from nutritional standpoint. The physiological functions of fat are energy yielding as well as the carrier of fat soluble vitamins, with special activities of essential fatty acids. It is fortunate that Korean families prefer to use vegetable oils rather than those from animal origin. But the problems are focused on better qaulity of food oils with attempt to exploit the available resources. This study was undertaken to inevestigate the fatty acid compositions of Korean origin both from conventional and unconventional resources of gas-liquid chromatography. The results obtained are as follows. 1. The total lipid contents of seeds of red pepper, Korean squash, sesame, perilla (var Japonica), and Korean pine nuts and walnuts were 24.3%, 56.6%, 56.4%, 46.9%, 69.8%, and 67.2%, respectively. 2. The saponification numbers of samples ranged from 190 to 200. It showed that the mean molecular weights of fatty acids composing the lipids were very much closed each other. 3. Iodine numbers of varing seed oils ranged from 96.5 of Korean squash seed oil to 124.6 of walnut oil. Oils obtained from squash seeds and sesame seeds showed significantly lower value, while others ranged from 122 to 125. 4. In the fatty acid compositions, squash seed oil was composed mainly of unsaturated fatty acids, 74.9% of which was oleic acid, whereas red pepper seed oil, pine nut oil, and sesame oil contained linoleic acid as a major component showing 64.4%, 56%, 48.8%, and 47.8%, respectively. In perilla seed oil, the amounts of linoleic and linolenic acids were 14.1% and 58%, respectively which meant nearly three-fourths of the total fatty acidsbeing the unsaturated essential fatty acids. This study will encourage the use of these conventional and unconventional vegetable oils which have highr ratios of polyunsaturated to saturated fatty acids.

향신성 식용유는 에너지원이나 대사조절물질로서뿐 아니라 식품의 맛이나 향 또는 포만감을 결정하는 지방이다. 본 연구는 0.12% 콜레스테롤 식이를 한 흰쥐에서 대두유를 대조로 하여 향신성 식용유(고추종실유, 산초유)에 의한 지질농도의 조절효과를 평가하였다. 사료중 n-6/n-3 지방산의 비는 8.8:1.2:70.1 (대두유:산초유:고추종실유)로 큰 차이가 있었다. 혈청콜레스테롤 농도는 고추종실유 섭취군에서 다른 군보다 높았으나, HDL-cholesterol/totalcholesterol 비는 고추종실유 섭취군에서 낮았다. 혈청중성지질 농도는 다른 군에 비하여 산초유 섭취군에서 낮았다. 반면에 간장 콜레스테롤 농도는 고추종실유 섭취군보다 산초유 섭취군에서 높았다. 이러한 응답은 식이지방에 의한 혈청 콜레스테롤 농도의 응답은 조직간 콜레스테롤 분배의 차이에 기인되는 듯하다. 결론적으로 본 연구는 콜레스테롤 함유식이를 한 흰쥐에서 고추종실유는 대두유에 비하여 콜레스테롤상승효과를 보여준 반면, 산초유는 중간적 효과를 보여주었다.

The contents of sterols and stanols in vegetable oils and mist oil were analyzed by gas chromatography using a capillary column. The total sterol contents showed high values of 0.67~0.89g/100g in corn oil, rice bran oil, red pepper seed oil and sesame oil. Mist oil, a byproduct of soybean oil manufacture, was a suitable raw material for the production of stanol since it showed high sterol content (10.2g/100g). In the hydrogenation of sterol contained in mist oil using Pd catalyst, the effects saponification of oil were examined. The conversion of sterol to stanol was improved by a factor of 4~5 through saponification of oil, compared to the reaction without saponification.
