Conjugated Linoleic Acid Production and Optimization Via Catalytic Reaction Method Using Safflower Oil

نویسندگان

چکیده مقاله:

Conjugated linoleic acid (CLA) is one of the most physiological active fatty acids due to its positive effect on  prevention of diseases such as obesity, hyperlipidemia, atherosclerosis and cancer. The aim of this study was to optimize the production of conjugated linoleic acid (CLA)% in  alkali isomerization of safflower oil including  71% linoleic acid (LA)  using response surface methodology (RSM). The effect of three reaction variables such as temperature, reaction time and amount of KOH on CLA production was investigated using design-expert software. The optimal condition determined at this point, 72% total CLA with the yield of 84% temperature reaction time and the amount of KOH were 187.6 ºC, 2.12 h 48.7 g; respectively. Further results indicate that just two reaction parameters including temperature and the amount of catalyst have significant effects on CLA production %; however,the reaction time showed negligible impact on CLA production.

Supplemental safflower oil affects the fatty acid profile, including conjugated linoleic acid, of lamb.

The objective of this study was to determine whether increasing levels of dietary safflower oil would alter unsaturated fat (especially CLA) and tocopherol content of lamb, animal performance, carcass characteristics, or color stability of lamb muscle tissue. Targhee x Rambouillet wethers (n = 60) were assigned to one of three diets (four pens per treatment with five lambs per pen) in a complet...

Mesoporous Aluminosilicates as Catalyst Supports for Conjugated Linoleic Acid Formation by Hydrogenation/Isomerisation of Safflower Oil

Introduction During catalytic hydrogenation of vegetable oils, some of the naturally occurring cis double bonds are isomerized to trans fatty acids (TFA). High levels of trans fats in the diet are linked to higher occurrence of coronary health diseases [1]. However, all trans fatty acids are not harmful, some conjugated linoleic acid (CLA) isomers are reported to have anticarcinogenic, -atherog...

Optimization of the Hydrolysis of Safflower Oil for the Production of Linoleic Acid, Used as Flavor Precursor

Commercial lipases, from porcine pancreas (PPL), Candida rugosa (CRL), and Thermomyces lanuginosus (Lipozyme TL IM), were investigated in terms of their efficiency for the hydrolysis of safflower oil (SO) for the liberation of free linoleic acid (LA), used as a flavor precursor. Although PPL, under the optimized conditions, showed a high degree of hydrolysis (91.6%), its low tolerance towards h...

Conjugated linoleic acid-enriched beef production.

Canadian beef consumption is approximately 31 kg per annum, or a third of all meats consumed. Beef is a nutrient-rich food, providing good quality protein, vitamins B-6 and B-12, niacin, iron, and zinc. However, animal fats have gained the reputation of being less healthy. The identification of the anticarcinogenic effects of beef extracts due to the presence of conjugated linoleic acid (CLA) h...
