The safety evaluation of phytosterol esters. Part 6. The comparative absorption and tissue distribution of phytosterols in the rat

Food and Chemical Toxicology, 2000
As part of an extensive safety evaluation programme, a series of studies has been conducted to determine the fate of phytosterols in the rat. Rats were dosed by oral gavage with 14C-labelled samples of cholesterol, beta-sitosterol or beta-sitostanol or (3)H-labelled samples of beta-sitostanol, campesterol, campestanol or stigmasterol dissolved in ...

Solid base catalysts for the synthesis of phytosterol esters

Green Chemistry, 2003
The main objective of this study is the synthesis of phytosterol esters from natural sterols and methyl esters in the presence of basic solid catalysts which are less corrosive and more selective than homogeneous catalysts such as alkaline hydroxides and carbonates.

Safety Evaluation of Phytosterol Esters. Part 2. Subchronic 90-Day Oral Toxicity Study on Phytosterol Esters–A Novel Functional Food

Food and Chemical Toxicology, 1999
Phytosterol esters (PE) are intended for use as a novel food ingredient, primarily in margarines and spreads as a functional component with plasma cholesterol lowering activity. Phytosterols and their esters are present naturally in vegetable oils and on average people consume 200 mg/day, but their consumption at this level is not sufficient to lower ...

Novel Synthesis of Steryl Esters from Phytosterols and Amino Acid

Journal of Agricultural and Food Chemistry, 2011
The feasibility of esterification of phytosterol with the amino acid l-glutamic acid was established. The influence of various organic solvents was investigated, and n-butanol was selected as an ideal solvent for phytosteryl esters synthesis with l-glutamic acid.

Analysis of sitosteryl oleate esters in phytosterols esters enriched foods by HPLC–ESI-MS2

Steroids, 2014
Phytosteryl esters (PE)-enriched spreads are marketed for eating and cooking purposes. Temperature and also light exposure are the major factors leading to the formation of PE oxides in food matrix. In this study a high-speed HPLC-MS(2) method was developed to analyze the major PE present in PE-enriched spreads: sitosteryl oleate (SO) and its oxidation

Physical and chemical properties of milkfat and phytosterol esters blends

Food Research International, 2007
Abstract Over the past few decades, consumption of butter has declined due to its high content of saturated fatty acids and cholesterol. Opposingly, phytosterol esters (PE) have been used as a food ingredient for their effectiveness in lowering plasma cholesterol levels.

Phytosterols, phytostanols and their esters: from natural to functional foods

Mediterranean Journal of Nutrition and Metabolism, 2011
Phytosterols, phytostanols and their esters are a group of steroid alcohols that occur naturally in plants. As natural constituents of plant structures, phytosterols contribute to the regulation of the fluidity and permeability of cell membranes. They are found mostly in vegetable oils, fruits, nuts, cereals and legumes.

Production of phytosterol esters from soybean oil deodorizer distillates

European Journal of Lipid Science and Technology, 2009
AbstractEnzymatic esterification and supercritical fluid extraction was used to produce phytosterol esters from soybean oil deodorizer distillates. The raw material was first subjected to a two‐step enzymatic reaction; the product obtained mainly comprised fatty acid ethyl esters, tocopherols and phytosterol esters, together with minor amounts of ...

Simulation and optimization of supercritical fluid purification of phytosterol esters

AIChE Journal, 2009
AbstractSupercritical carbon dioxide extraction to separate phytosterol esters from fatty acid esters and tocopherols was simulated and optimized using the group contribution equation of state. Experimental extraction data at 328 K, pressures ranging from 200 to 280 bar and solvent‐to‐feed ratio around 25, was employed to verify the performance of the ...

Novel Synthesis of Phytosterol Ester from Soybean Sterol and Acetic Anhydride

Journal of Food Science, 2016
Abstract Phytosterols are important bioactive compounds which have several health benefits including reduction of serum cholesterol and preventing cardiovascular diseases. The most widely used method in the synthesis of its ester analogous form is the use of catalysts and solvents. These methods have been found to
