The calciumiron connection inside ferroptosismediated neuronal dying
Chewing time of two hazelnuts was significantly shorter than chewing time of six hazelnuts or chewing time of two hazelnuts in white bread or baguette, while chewing frequency did not differ between foods. d50 of six hazelnuts did not significantly differ from d50 of two hazelnuts in either bread matrix. Broadness b of the particle size distribution was significantly smaller for six hazelnuts compared to the other foods. We conclude that d50 was affected by bite size or bite volume rather than by incorporation of hazelnuts into bread. We suggest that incorporation of hazelnuts into bread matrixes has a relatively small impact on size of hazelnut bolus particles produced upon mastication.Using the INFOGEST in vitro digestion protocol adapted to carotenoids, the impact of additional rabbit gastric lipase (RGL) on the hydrolysis extent of β-cryptoxanthin esters was evaluated for the first time, and compared with the addition of porcine cholesterol esterase (CEL). Both the modifications increased the hydrolysis of (all-E)-β-cryptoxanthin esters from mandarin and peach pulps, although the outcomes were different. Addition of RGL consistently increased the average hydrolysis extent from 55.2% to 59.5% in mandarin pulp and from 22.7% to 48.8% in peach pulp (p less then 0.05). The addition of CEL produced lower hydrolysis extents, i.e., 58.5% in mandarin (not statistically significant) and 28.4% in peach (p less then 0.05), compared to those obtained with RGL. The hydrolysis extent positively correlated with the carotenoid ester concentration in both matrices. Bioaccessibility values were higher in mandarin pulp (range 32-34%) compared to those in peach pulp (range 16-21%), and were associated with the hydrolysis extent of the carotenoid esters during digestion. Addition of RGL and CEL produced no significant (p less then 0.05) effect on the overall carotenoid bioaccessibility values of mandarin, while positively affected those in peach. Altogether these results corroborate that the hydrolysis extent of xanthophyll esters limits bioaccessibility. Additionally, hydrophobicity of the carotenoid inversely correlates with micellarization, as free (all-E)-xanthophylls micellarized in a higher extent compared to (all-E)-β-carotene and xanthophyll esters. ABT-199 The new information of our results is that the addition of rabbit gastric lipase substantially contributes to the hydrolysis of β-cryptoxanthin esters from fruit pulps, and consequently, to increase carotenoid bioaccessibility, being even more effective than CEL.Crustacean byproducts are valuable sources of astaxanthin. In this study, an astaxanthin-rich lipid phase was extracted from shrimp waste and encapsulated in multilayer emulsions. Stabilized by electrostatic complexes of whey protein isolate (WPI) and Persian gum (PG), the multilayer emulsions were created by different WPIPG mixing ratios (12-14). The resultant emulsions were then exposed to lyophilization. The encapsulation efficiency of astaxanthin in lyophilized powders was 42.9-49.8 (g astaxanthin/100 g astaxanthin). The moisture content and water activity of the powders decreased significantly (p less then 0.05), but their solubility and hygroscopicity increased significantly (p less then 0.05) in response to an increase in the PG content of the mixture (or by reducing the WPIPG ratio). Morphological characterizations revealed the formation of smaller and more uniform microcapsules when higher amounts of PG were used. Water dispersibility was higher than 94 (g powder/100 g powder). The results of an accelerated stability test showed an improvement in astaxanthin chemical stability in the multilayer emulsions, particularly when the WPIPG ratio was 14. A model beverage consisting of water (89 g/100 g), sugar (10 g/100 g) and citric acid (1 g/100 g) was prepared and the potential application of astaxanthin microcapsules as a natural colorant was studied and compared with a synthetic colorant (E110) under the effect of light/darkness, temperature (4 and 25 °C) and time (0-60 d). The encapsulated lipid extract imparted a highly stable color to the product which was comparable to the effect of the synthetic colorant. However, the astaxanthin concentration was highly affected by time and partially affected by light and temperature.In this study, fruit-zone microclimate was modified by three treatments, including inter-row mulch (M), the combination of leaf removal applied at the onset of veraison and inter-row mulch (MLR-BV), and the combination of leaf removal applied at complete veraison and inter-row mulch (MLR-EV), in a semi-arid climate in three consecutive years (2015-2017). M decreased fruit-zone reflected solar radiation from vineyard floor and low temperature (10-20 °C) duration, whereas it increased soil temperature and high temperature (> 30 °C) duration. MLR-BV and MLR-EV increased fruit-zone incident photosynthetically active radiation while decreased the duration of 20-25 °C compared to M. Notably, M significantly decreased grape total norisoprenoid concentrations in 2015-2017, and total terpenoid concentrations in 2015-2016. Applying leaf removal applied at the onset of veraison could compensate the decreases of total norisoprenoids and terpenoids caused by M when two treatments were applied together. Besides, M significantly increased grape total C6/C9 compound concentrations, besides, (Z)-3-hexen-1-ol concentrations were significantly higher in grapes of M than those of MLR-BV in 2015-2017. Light exposure and high temperature duration after veraison had strong positive correlations with total norisoprenoids and terpenoids, besides, low temperature duration was positively correlated with total norisoprenoids. In addition, light exposure after veraison had strong negative correlations with total C6/C9 compounds. With respect to the volatile compounds in wines, M significantly decreased the concentrations of isopentanol and ethyl acetate, and the concentrations of ethyl cinnamate, phenylacetaldehyde, phenylethyl alcohol and 3-methylthio-1-propanol were significantly lower in MLR-BV and MLR-EV than in M. The outcome of this study can assist winegrowers to properly adjust vineyard managements to optimize the concentrations of desired volatile compounds in grapes and wines.
