브로일러에 대한 Canola seed와 Canola meal＋oil의 사료가치를 알아보기 위해 2가지 시험이 실시되었다. 시험 1에서, 가열 또는 가열처리 되지 않은 Canola seed와 Canola meal＋oil 또는 fat등 4가지 시료가 broiler사료에 10％씩 배합되었으며, 시험 2에서는 Canola seed와 Canola meal＋oil이 각각 broiler사료에 10％또는 20％씩 배합 급여되었다. Broiler의 능력이나 시험사료의 영양소 이용율 등에서 Canola seed의 열처리 효과는 없었으며, Canola meal과 혼합된 Canola oil과 animal fat의 효과간에도 차이가 없었다. Canola seed나 Canola meal＋oil은 모두 10∼20％ 급여수준에서 대조구와 broiler능력에 차이가 없었다. 결론적으로 Canola seed와 Canolameal＋oil은 모두 broiler사료에 10∼20 ％까지 사용할 수 있었다.

This project was to compare the effects of consuming diets incorporating soybean oil , canola oil, ad palm oil on blood serum lipid patterns and fecal fat excretion in healthy human adults. The project was composed of three studies that were run concurrently . Each study was composed of a 4-day pre-trial period and two , 14-day experimental periods arranged according to a cross-over design. During the pre trial period, subjects were allowed to eat self-selected diets. During the experimental period , subjects were asked to eat constant, laboratory controlled diets in which sources of dietary fat varied . Thirty healthy , young adult subjects were fed a laboratory controlled diet incorporating soybean oil, canola oil, and palm oil. Test oils provided approximately 20% of the total dietary calories form all sources. Total dietary fat from all sources was approximately 30% of consumed calories. The highest serum total cholesterol , LDL cholesterol, VLDL cholesterol , and triglyceride values occurred when pam oil diets were eaten. However, feeding on palm oil diets resulted in the same HDL cholesterol content as with soybean oil or canola oil diets. Soybean oil diets produced numerically lower blood serum total cholesterol , LDL cholesterol, and triglycerides, and numerically higher HDL cholesterol and VLDL cholesterol than did those with canola oil. Fecal fat excretion was numerically lower with soybean oil diets than with canola diets. The highest fecal fat excretion occurred when palm oil diets were eaten.

Potato chip을 제조시 canola유를 선택하여 potato chip을 제조하는 과정에서 발생하는 potato chip의 기름 함량이 40%정도까지 흡수하게 되는데 이 흡수된 기름이 저장과 유통되는 동안 potato chip의 품질을 유지하는데 결정적인 영향을 주므로 항산화제인 BHA, BHT, TBHQ와 silicone유를 첨가한 첨가 유의 항산화제 효과를 관능 검사와 함께 비교 고찰하였다. Potato chips에서 추출한 oil의 항산화제 효과는 canola oil+TBHQ (0.02%)+silicone (10 ppm)에서 가장 우수한 항산화 효과가 있었고 다음은 canola oil+TBHQ로 안정한 것으로 나타났으며 항산화제를 단독으로 사용한 것보다 silicone을 첨가한 것이 탁월한 안정성을 보였고 항산화제로서 TBHQ가 매우 효과가 있었고 silicone를 첨가한 유지에서 탁월한 저장 안정성을 유지하는 것으로 나타났다. 관능검사 결과 canola oil은 2개월부터 overall, flavor, aftertaste의 변화에 약간의 유의차를 나타내었으며 TBHQ과 silicone을 첨가한 oil는 2개월에서는 전 항목에서 변화가 없었고 4개월부터 overall, flavor, freshness, aftertaste의 항목에서 유의차를 나타내었으며 따라서 2개월 정도 저장 안정성이 연장되는 효과가 있는 것으로 나타났다.

Korean traditional meat patties (Tteokgalbi) were prepared by replacing part of the lean meat content with either pork backfat or canola oil and the effect of substitution on sensory quality of the meat patties was investigated. Compared to the control patties, pork-loin Tteokgalbi with 10% pork backfat or 10% canola oil had significantly higher overall acceptability and higher perceived intensity of meat flavor, sweetness, umami, and oiliness. The pork-loin patties containing 10% fat also had lower perceived firmness, toughness, and chalkiness of than the control Tteokgalbi. The chicken breast Tteokgalbi with 10% canola oil had the lowest perceived firmness and chalkiness (control > pork backfat > canola oil). No significant difference was noted in the overall acceptability of chicken breast patties with 10% pork backfat and those with 10% canola oil. These results indicate that substituting 10% of lean meat of Tteokgalbi with fat improved the sensory acceptability of the product for Korean customers regardless of the lean meat and/or fat source used in the patties. Lean meat patties formulated with a limited amount of vegetable oil such as canola oil can be a healthy option for Korean consumers by providing desirable fatty acid profiles without sacrificing sensory quality of the product.

In manufacturing operations, oil plays a crucial role in reducing friction and wear among interacting surfaces at varying velocities, loads, and temperature. Hydrocarbon oil is considered the origin of lubrication oils. However, this base oil has been limited in its use as it is a principal cause of pollution. This research focuses on identifying a biodegradable base oil lubricant that possesses a stable coefficient of friction and viscosity with temperature. Friction analysis is conducted by employing a pin on a disk tribotester with a fixed load of 10 N at varying sliding speeds ranging from 0.06 m/s to 0.34 m/s. Oil viscosity analysis is perfomed at room temperature by using a rotary viscometer. Tests are performed using canola oil and paraffin oil as lubricants. The results indicate that the viscosity of canola oil is more efficient than paraffin oil. The non-dimensional characteristic number according to the Stribeck curve reveals an elastohydrodynamic lubrication regime with canola oil lubrication. A comparison of both lubricants reveals that, the friction efficiency of canola oil and paraffin oil does not differ considerably. However, the friction in canola oil is observed to decrease more than that in paraffin oil at an elevated sliding speed. The tests confirm that canola oil is potent in minimizing the friction coefficient of SCM440 bodies interacting with one another as well as acted upon by load.

Seventy-two crossbred pigs weighing an average of 41.5 kg were assigned on the basis of sex, weight and litter to one of four dietary treatments in a factorial (4 treatments${\times}$2 sexes) arrangement. The control diet was based on barley and soybean meal while the experimental treatments consisted of diets in which a portion of the dietary protein was supplied by 20% of a 50:50 blend of extruded ($130^{\circ}C$ for 20 to 25 sec) peas and full-fat canola seed, 20% of a 50:50 blend of unextruded peas and full-fat canola seed or a diet containing 10% peas, 6% canola meal and 4% canola oil (to equal the level of canola oil provided by 10% whole canola seed). Digestibility coefficients for dry matter, crude protein and gross energy were significantly higher (p<0.05) for the control diet than for the other three diets. Extrusion produced no beneficial effects (p>0.05) on nutrient digestibility and there were no differences in digestibility between the diet based on intact canola seed compared with the diet containing canola meal and oil. Choice of protein supplement had no significant effects on gain, feed intake or feed conversion during the grower or finisher phases and over the entire experimental period. Extrusion of the pea-canola blend produced no beneficial effects on pig performance as the performance of pigs fed either the extruded or unextruded blend of peas and canola seed was similar. In addition, the performance of pigs fed diets containing intact canola seed was similar to that of pigs fed canola meal and oil. Castrates gained faster and consumed more feed than gilts (p<0.05). However, their feed conversion was poorer than that of the gilts during the finisher period. There were no significant differences in carcass traits between pigs fed the control and any of the experimental treatments. Extrusion had no effect on carcass traits and the carcasses of pigs fed canola meal and oil did not differ from those of pigs fed whole canola seed. Castrates had a significantly lower dressing percentage, lower estimated lean yield but greater loin fat depth than gilts (p<0.05). The results of this experiment indicate that peas in combination with canola seed or canola meal are an acceptable alternative to soybean meal as a protein supplement for use in growing-finishing swine diets. Extrusion did not appear to have any beneficial effects on the nutritional value of the canola seed-pea blend as nutrient digestibility, growth performance and carcass traits were similar for pigs fed the unextruded blend of peas and canola seed compared with the extruded product. Since the process adds to the cost of the raw products, its use is unlikely to be economical.

Faecal pH and cholate are two important factors that can affect colon tumorigenesis, and can be modified by diet. In this study, the effects of two Chinese traditional cooking oils (pork oil and canola/rapeseed oil) on the pH and the cholic acid content in feces, in addition to colon tumorigenesis, were studied in mice. Kunming mice were randomized into various groups; negative control group (NCG), azoxymethane control group (ACG), pork oil group (POG), and canola oil Ggroup (COG). Mice in the ACG were fed a basic rodent chow; mice in POG and COG were given 10% cooking oil rodent chow with the respective oil type. All mice were given four weekly AOM (azoxymethane) i.p. injections (10mg/kg). The pH and cholic acid of the feces were examined every two weeks. Colon tumors, aberrant crypt foci and organ weights were examined 32 weeks following the final AOM injection. The results showed that canola oil significantly decreased faecal pH in female mice (P<0.05), but had no influence on feces pH in male mice (P>0.05). Pork oil significantly increased the feces pH in both male and female mice (P<0.05). No significant change was found in feces cholic acid content when mice were fed 10% pork oil or canola oil compared with the ACG. Although Kunming mice were not susceptible to AOM-induced tumorigenesis in terms of colon tumor incidence, pork oil significantly increased the ACF number in male mice. Canola oil showed no influence on ACF in either male or female mice. Our results indicate that cooking oil effects faecal pH, but does not affect the faecal cholic acid content and thus AOM-induced colon neoplastic ACF is modified by dietary fat.

The aim of this study was to examine the effects of perilla oil as well as several vegetable oils, including flaxseed oil, canola oil, and rice bran oil on plasma levels of cardioprotective (n-3) polyunsaturated fatty acids in mice by feeding each vegetable oil for a period of eight weeks. Concentrations of docosapentaenoic acid (DHA) and eicosapentaenoic acid (EPA), fish-based (n-3) polyunsaturated fatty acids, showed an increase in the plasma of mice fed perilla and flaxseed oils compared to those of mice in the control group (P < 0.05), whereas rice bran and canola oils did not alter plasma DPA and EPA concentrations. Arachidonic acid concentration was increased by feeding rice bran oil (P < 0.05), but not canola, flaxseed, or perilla oil. In addition, oleic acid, linoleic acid, and docosahexaenoic acid concentrations were altered by feeding dietary rice bran, canola, perilla, and flaxseed oils. Findings of this study showed that perilla oil, similar to flaxseed oil, is cardioprotective and could be used as an alternative to fish oil or even flaxseed oil in animal models.
