ABSTRACT
Understanding the effects of processing on the Se content and bioaccessibility in food is critical in guiding the development of Se-enriched products. In this study, Se-enriched Pleurotus eryngii was obtained by applying different Se supplements to the substrate. Selenium content and its bioaccessibility among raw and processed fruit bodies were compared. The application of exogenous Se had no significant effect on the yield of P. eryngii, while amendment Se yeast could slightly promote the growth of P. eryngii. The enrichment ability of P. eryngii among different Se supplements declined in the order of Na2SeO3 > Se yeast > Na2SeO4. However, the processing treatments resulted in 6.6%-45.9% Se loss. The Se bioaccessibility of P. eryngii was 78.4%-89.7%. Frying treatment reduced Se bioaccessibility in samples, whereas boiling treatment enhanced it. Therefore, Se yeast and boiling treatment are recommended as the ideal Se supplement and processing method for Se-enriched P. eryngii.
