What is the phytosterol content of various plant foods?
Best insight from top research papers
Phytosterol content varies among different plant foods. Oil and cereal seeds are the largest natural sources of phytosterols, with amaranth having the highest concentration . Vegetable oils have the highest total phytosterol content, followed by legumes, nuts, and cereals . The phytosterol content in vegetables and fruits is generally lower . The phytosterol content in food plant materials ranges from 14.8 mg/100 g to 208.3 mg/100 g, while in Chinese traditional herbal medicines, it ranges from 9.4 mg/100 g to 280.3 mg/100 g . Beta-sitosterol is the predominant phytosterol in most samples .

How can the solubility of phytosterols be increased?5 answersThe solubility of phytosterols can be increased through various methods. One approach is the formation of complexes with phospholipids, such as phospholipon® 90H, which enhances solubility and chemical stability. Another method is the encapsulation of phytosterols in nanoparticles, such as sodium caseinate (NaCas)/pectin-based nanoparticles, which improve bioaccessibility. Additionally, the use of emulsification-evaporation combined with high-pressure homogenization can result in phytosterol nanoparticles with increased solubility and bioaccessibility. Furthermore, enzymatic synthesis of phytosterol polyol esters using divinyl adipate and polyols has been shown to enhance solubility and bioaccessibility. These approaches offer potential strategies for improving the solubility of phytosterols, which can have implications for their use in various applications, including pharmaceuticals and food ingredients.
Can injected phytosterols act as endocrine disruptors?4 answersInjected phytosterols can potentially act as endocrine disruptors. Phytosterols are natural compounds found in plants and are consumed by the general population to lower cholesterol levels. The study on European polecats showed that phytosterols increased plasma estradiol and thyroid hormone levels, while decreasing plasma ghrelin levels. These effects indicate that phytosterols can have an impact on the endocrine system. However, it is important to note that the definition of endocrine disruptors is broad and includes substances that cause changes in endocrine function leading to adverse effects. Therefore, further research is needed to fully understand the potential endocrine-disrupting effects of injected phytosterols.
What are the 10 most frequent phytosterols?4 answersPhytosterols are plant sterols that are commonly found in plants and vegetable oils. The most frequent phytosterols include β-sitosterol, campesterol, stigmasterol, avenasterols, and stanols. Other phytosterols that are also present but less commonly mentioned include sitostanol, campestanol, and brassicasterol. These phytosterols are naturally occurring in various plant-based foods such as vegetable oils, fruits, nuts, cereals, and legumes. Rice bran is considered to be the best source of phytosterols, containing high concentrations of sterols such as sitosterol, campesterol, and stigmasterol. The distribution of various steryl conjugates, such as esters with fatty acids, esters with phenolic acids, glycosides, and acylated glycosides, is also of interest when evaluating phytosterol sources.
Which analytical methods are suitable for phytosterols?5 answersAnalytical methods suitable for phytosterols include gas chromatography (GC) after derivatization, liquid chromatography (LC), and mass spectrometry (MS). GC coupled with flame ionization detection can be used for phytosterol analysis in rice products. LC-MS has the potential to simplify the analysis by eliminating the need for derivatization, which is usually required for GC-MS. HPLC analyses of phytosterols can be improved through chemical derivatization using dansyl chloride as a derivatizing agent. Near-infrared spectroscopy (NIRS) coupled with chemometric techniques can also be used for rapid and non-destructive analysis of phytosterols in vegetable oils.
What quanities of phytosterols are there in sesame seeds?5 answersSesame seeds contain various quantities of phytosterols. The phytosterols found in sesame seeds include β-sitosterol, campesterol, stigma-sterol, Δ-5 avenasterol, and sesamin. Other phytosterols such as cholesterol, clerosterol, Δ-5,24 stigmastadienol, Δ-7 avenasterol, eritrodiol, and Δ-7 stigmasterol are also present, but in lower levels. The specific amounts of these phytosterols in sesame seeds are not mentioned in the abstracts provided. However, it is mentioned that sesame seeds are a rich source of phytosterols, along with other nutrients such as oil, protein, minerals, and lignans.
Can phytosterols modulate the liver lipidomic profile in obese murine?3 answersPhytosterols have been shown to modulate the liver lipidomic profile in obese murine models. Studies have demonstrated that dietary phytosterols can decrease liver fatty acids and cholesterol contents, as well as regulate the activities of lipid metabolism enzymes such as acetyl-CoA carboxylase and malic enzyme. Additionally, phytosterol consumption has been found to reduce the absorption of dietary cholesterol and alter the tissue fatty acid composition, with significant decreases in cholesterol levels observed in the liver. Furthermore, phytosterols have been shown to restore the homeostatic equilibrium of the hepatic metabolome, indicating their ability to modulate liver metabolism. These findings suggest that phytosterols can indeed have an impact on the liver lipidomic profile in obese murine models, making them a potential target for therapeutic interventions.
