Embodiment 1
[0043] Embodiment 1: preparation is based on the stanol fatty acid ester of low saturated soybean oil fatty acid (LowSatSoy)
[0044] Small-scale production of stanol fatty acid esters. 6 kg of commercially available phytostanols (composition: 68.2% sitostanol, 28.3% campestanol, 1.1% sitosterol and traces of other unsaturated sterols) obtained by hydrogenation were mixed with 8.6 kg LowSatSoy The methyl ester mixture was blended and dried at 110-120°C. The temperature of the dry mixture was lowered to 90-95°C and sodium methoxide catalyst (73 g) was added. The temperature was increased to 120°C and the reaction was carried out under vacuum (40 mmHg) for 4 hours. Conversion was controlled by GC analysis. Once a conversion of greater than 98% was achieved, the temperature was lowered to 100°C and 30% by weight of hot water greater than 90°C was added to destroy the catalyst. The water phase was removed and the oil phase was washed again to bring the soap content to less than ...
Embodiment 2
[0045] Example 2: Preparation of vegetable oil-based stanol fatty acid esters with fatty acids derived from linola oil
[0046] A stanol fatty acid ester blend with fatty acids derived from linola oil was prepared using the same phytostanol blend and method as described in Example 1. The fatty acid composition of the obtained phytostanol esters was as follows: SAFA: 10.6%, MUFA: 17.7% and PUFA: 71.8%. The contents of C16:0 and C18:0 were 6.2% and 3.9%, respectively. The stanol content was 57.9% by weight, with a high conversion rate of esterification (the amount of free stanol was 0.13% by weight).
Embodiment 3
[0047] Example 3: Preparation of phytostanol fatty acid esters based on distilled high PUFA fatty acids derived from sunflower oil
[0048] Using a procedure similar to that described in Example 1, high PUFA phytostanol esters were produced using fatty acid methyl esters obtained after distillation of sunflower oil-based methyl esters. The combined distilled fractions contained 5.6% SAFA (0.3% C16:0, 5.0% C18:0), 26.5% MUFA and 67.9% PUFA. The total sterol (phytosterols + phytostanols) content of the phytostanol esters was 59.5%, while the phytostanol content was 58.4% by weight. The amount of free stanols is 0.86%.
