Special Issue Information

Dear colleagues,

Several foods (margarine spreads, yogurt, low-fat milk, fruit juices, and rye bread) can be enriched with plant sterols (PS) to provide them with cholesterol-lowering properties. In the last 20 years, the commercialization of these enriched products has increased, since several of their health claims have been accepted.

The main goal of this Special Issue is to provide new insights and data (original research and review articles) on the advances in different aspects related to PS-enriched foods:

- New sources and encapsulation techniques for the enrichment of foods with sterols and technological stability

- Formation of oxidative products during technological and culinary treatments and their safety assessment

- Updated data on the evaluation of PS intake and consumer perception, current trends in production and consumption patterns of PS-enriched foods

- Determination of PS bioaccessibility from PS-enriched foods, applying harmonized simulated gastrointestinal digestion methods

- Effect of other bioactive components present in food (fiber, prebiotics, curcumin) on PS bioavailability from PS-enriched foods

- New data on PS biological effects from in vitro, animal, and human assays, especially related to compounds that enhance the cholesterol-lowering effect, the influence of genetics on the effectiveness of PS, the anticancer and anti-inflammatory activities of PS, and their beneficial properties in the prevention of neurological disorders.

New phytosterol (PS)-enriched sunflower seeds, which are higher in campesterol and ∆7-stigmastenol, have recently been developed. Crude oils obtained from these new sunflower seeds in 2015 and 2017 were used in this study. Oils extracted only by press (PO) and with subsequent solvent extraction (SO) were characterized. Physical refining (PhR) was used to obtain edible PO by minimal processing and to keep the PS levels as high as possible. Oils obtained by chemical processing were also studied for comparative purposes. Different bleaching treatments were examined to reduce the contents of phospholipids in the PO to levels required for PhR (<10 mg kg−1). Phosphorous levels in PO from 2015 (9–12 mg kg−1) were reduced to optimal levels by bleaching with 0.1% Trisyl and 1% Tonsil 278 FF. Contrarily, treatments with Trisyl and Tonsil (278 FF or 114 FF) were not sufficient to reduce the higher levels in PO from 2017 (15–36 mg/kg−1), thereby they were subjected to chemical refining (ChR). The PhR applied to PO from 2015 did not lead to substantial changes in the composition and total content of PS. In contrast, losses of up to approximately 30% of total PS were found owing to ChR, although the oils preserved their unique PS profiles. Full article
