Nutraceutical stability in Lentinus squarrosulus after drying and frying for snack production

Abstract

Pathogenesis of neurological diseases is associated with free-radical-mediated inflammatory processes. Phenolic compounds, saponin, and γ-aminobutyric acid (GABA) are nutraceuticals with neuroprotective properties. Lentinus squarrosulus is a mushroom with high proteins low calories, and nutraceuticals. This research aimed to investigate the nutraceutical contents of total phenolic compounds, saponins, γ-aminobutyric acid (GABA), and antioxidant activity in this mushroom after drying and frying for snack production. The nutraceutical contents and antioxidant activity were measured by Folin–Ciocalteu method and 2,2-diphenylpicrylhydrazyl (DPPH) assay, respectively. The stability of these nutraceuticals was also determined after drying and deep frying mushrooms in preparation for snack production. Results showed that the mushrooms after drying at 50 and 60 °C until the moisture content was below 12 % (according to Thai Community Products Standard) had water activity (aW) of 0.52 to 0.59. The dried mushrooms had lower lightness, redness, and yellowness with the increased drying temperature (p ≤ 0.05). The total phenolic content of dried mushrooms was not significantly different from that of fresh mushrooms, but saponin, GABA, and antioxidant activity were higher than in the fresh samples.

“…All treatments with additional CF had significantly less springiness, which indicated a strong influence of the presence of starch in the formulation that contributed to changing the textural properties of the MMMS matrix [54]. A low springiness value, on the other hand, suggests that the material was plastically deformed [55]. Moreover, the maximum chewiness was observed in formulations with 50% CF (0% PSC mushrooms).…”
