  • The effects of various dietary fats on plasma lipids. liver lipids, and Plasma Peroxide levels were studied in rats fed for 6 wk with diets containing 15 wt% fat, as sesame oil. raw perilla seed oil. roasted perilla seed oil, heated perilla seed oil. mackerel oil or beef tallow. TBA values of these lipids during 4 wk storage, and linolenic acid contents of three kinds of perilla seed oil were also measured. Linolenic acid contents of raw perilla seed oil. roasted perilla seed oil and heated perilla seed oil were 62.3%, 61.6% and 53.1% respectively. Raw perilla seed oil showed the lowest rate of lipid peroxidation after 4 wk storage at 4$^{\circ}C$, and mackerel oil showed the highest peroxidation rate. The plasma cholesterol levels of rats consuming diets in which the carbohydrate was rice were not affected by n-3 PUFA. Rather, the degree of peroxidation seems to have a direct effect on cholesterol levels as shown by the hypocholesterolemic effect of raw perilla seed oil and beer tallow. However. the HDL-cholesterol level was greater in rats fed either roasted perilla seed oil or mackerel oil. Rats fed roasted perilla seed oil and raw perilla seed oil had lower levels of plasma triglycerides than rats fed beef tallow. In rats fed roasted perilla seed oil, the total lipid and cholesterol contents of liver were significantly lower than in those fed the other kinds of perilla seed oil. The plasma lipid peroxide levels were lower in rats fed either roasted perilla seed oil or beef tallow.

  • This study was conducted to know the difference of major characteristics between seed and vegetable perilla varieties. Perilla accessions examined were classified into two groups, i.e., seed perillla variety (saeyeopcildeulkkae, yangsandeulkkae, and younghodeulkkae) and vegetable perilla variety (ipdlkkae 1, namcheondeulkkae, and manbaekdeulkkae). The differences of growth characteristics were observed between two types of perilla varieties. The average flowering date of vegetable perilla varieties (Sep. 28) was 23 days later than that of seed perilla varieties (Sep. 5). Also, the stem height and node numbers of vegetable perilla varieties lower than those of seed perilla varieties. The average 1,000-seed weight, yield, and oil content of seed perilla varieties were higher than those of vegetable perilla varieties. However, as leaf characteristic, the leaf yield (1.8 times) and cyanidin content (2.1 times) were greater than in perilla variety for vegetable. No difference was observed in fatty acids composition between two types of perilla varieties. The average total chlorophyll content in leaves of seed perilla varieties was higher than in that of vegetable perilla varieties.

  • To increase self-sufficiency ratio and agricultural income, six cropping systems by introducing several crops in perilla were tested from 2001 and 2002. Weed occurrence was high in barley+perilla and safflower+perilla cropping system. Pre-and post-crops in barley+perilla and safflower+perilla showed good growth. Safflower+perilla cropping system was labor-saying and cost down because polyethylene film of pre-crop was reused in post-crop. But when perilla was introduced as post-crop of sesame, delayed seed date resulted in decreased growth and grain yield. The income in barley+perilla and safflower+perilla was greater 4.1fold and 5.2fold, respectively than in perilla mono-crop system. Soil physical properties were improved in order of safflower+perilla, barley+perilla cropping system.

  • The rheological properties and sensory evaluation were investigated in the noodle from composite flours added with 0%, 10%, 20%, 30%, 40% of perilla flour. The maximum viscosity measured by amy lograph decreased gradually with the adding amount of perilla flour, while the gelatinization temperature increased with perilla flour. The weight and volume of the cooked noodle decreased with increasing perilla flour content. In the color of the noodle, lightness and yellowness decreased, but redness increased with increasing perilla flour content. Hardness and cohesiveness of the cooked noodle reduced, but adhesiveness increased with increasing perilla flour content. In sensory evaluation, the noodle with 20% perilla flour was evaluated the best in taste, texture and overall acceptability. Based on the cooking and sensory evaluation test, addition of 20% perilla flour to wheat flour is considered suitable for the noodle of perilla flour.

  • The aim of this study was to determine the optimum amount of perilla leaves to add to rice flour in the preparation of Sulgidduk(perilla leaf rice cake). By increasing the perilla leaf level in the formulation, the moisture contents of samples increased ($42.06{\sim}48.17%$), and their L-values decreased. The control and 16% perilla leaf Sulgidduk had higher a-values than the other samples, and the 8% perilla leaf Sulgidduk had the highest b-value. According to the mechanical evaluation results, hardness, gumminess, chewiness, and fracture decreased with increasing amounts of added perilla leaf. However, the springiness of samples during storage did not differ significantly according to the level of added perilla leaves. From the sensory evaluation results, the 12% perilla leaf sample received the highest overall-acceptability scores. In conclusion, according to its sensory and mechanical qualities, the optimal Sulgidduk formulation consisted of 12% perilla leaves added to rice flour.

  • This study was designed to select the most stable oil among vegetable oils for mayonnaise preparation on lipid oxidation when blended with perilla oil. Oxidative stabilities of perilla oil, soybean oil, rapeseed oil, corn oil, sunflower oil and perilla blended oils (blended perilla oil with other vegetable oil in a equal weight rate) were tested. Among the perilla blended oils, perilla blended soybean oil was the most effective on oxidative stability. This may be concerned with the fact that the content of natural antioxidant, tocopherol, is higher than that of other oils. Mayonnaise was prepared by using both perilla oil and perilla blended soybean oil. Variations of POV and tocopherol content of mayonnaise during storage at $37^{\circ}C$ were compared. The changes in POV and tocopherol content in the mayonnaise of perilla blended soybean oil were less than those of perilla oil. This result suggested that the usage of perilla blended soybean oil instead of perilla oil itself is possible in the manufacturing of mayonnaise.

  • As a result of testing cream soup prepared by adding variable amounts of freeze-dried perilla leaves, the moisture content was lowest at 86.91 for the cream soup containing 20% perilla leaves, and the pH was highest at 7.26 for the control group. The brightness was highest at 78.08 for the control group not containing perilla leaves, and the redness was lowest at -12.73 for PS20. The redness increased significantly (p>0.001) with increasing amounts of perilla leaves. As the amount of perilla leaves increased, the viscosity of the cream soup decreased gradually. In terms of bacteria, no microorganism was found until day 1. The control group with 0% camellia leaves contained $4.5{\times}10^3$ CFU/mL on day 3 and all groups contained microorganisms on day 5. The control group showed the highest content of microorganisms at $3.1{\times}10^4$ CFU/mL; PS20 containing the largest amount of perilla leaves showed the lowest content of microorganisms on day 7 and on day 10. The DPPH free radical removal activity of cream soup increased significantly (p>0.001) with the increasing amount of perilla leaves. In the sensory test, the color was highest at 5.3 for PS15 containing 15% perilla leaves, and there was no significant difference compared to that of the 10% group. The group with the lowest color was PS20. The fragrance was also highest at 5.6 for PS15, and the taste and after-taste were highest for PS10 containing 10% perilla leaves. Overall, the preference was highest at 5.3 for PS15 and lowest at 3.6 for PS20, with the greatest content of perilla leaves. Considering these findings, the optimal content of perilla leaves in cream soup would be 10~15%. Adding more than 20% perilla leaves would make the soup less preferable to the control group not containing any perilla leaves.
