Purple sweet potato (PSP) has abundant nutritional compounds, which are valuable constituents of the human diet, but its development and utilization are still in the primary processing phase. This study examined the differences in nutritional characteristics of 10 PSP varieties. A variety of nutritional components were evaluated and comprehensively compared using principal component analysis (PCA) and cluster analysis (CA). The PSP had 60.9–70.1% moisture. The dried PSP had abundant starch (43.9~67.2%) and dietary fiber (9.40~16.5%), moderate levels of protein (3.19~8.75%) and reducing sugar (1.44~4.01%), and low amounts of crude fat (0.51~1.01%). The anthocyanin profile varied significantly between the different varieties. A correlation analysis showed that a higher content of anthocyanins resulted in a darker color. The PCA and CA suggested that varieties XS, ZL, and JS18 are desirable for developing the diabetic patient’s diet. JS1 had the highest anthocyanin, protein, and dietary fiber contents and the lowest starch, implying that it could be used as a source of natural colorants or functional foods. Varieties FX, GS, ES13, and EN are suitable for producing various starch-based food products, such as noodles, cookies, and pastries. This study provides a reference for the practical use and rational processing of PSP resources.

Due to the increasing demand for biofuel feedstock production, Styrax tonkinensis , as a woody oilseed tree species, has received much more attention. However, the effects of various plant growth regulators on its seed development haven’t been explored deeply. Here, we applied 24-epibrassinolide (EBL) and methyl jasmonate (MJ) on the whole trees, and the aim of our study was to explore their effects on seed development of S. tonkinensis as well as seed chemical compositions, especially seed lipid metabolism. The results showed that EBL and MJ promoted the seed development, which was reflected in the increase of fresh and dry weight, as well as transverse and longitudinal diameter. The concentration of crude fat (CF) exhibited an ‘increase–decrease-increase’ trend, and the peak appeared at 70 days after flowering. EBL (in concentration of 5 μM, EBL5) and MJ (in concentration of 200 μM, MJ200) had the most significant effect on the accumulation of CF and the CF content in single seed. In addition, the activities of enzymes related to fatty acid (FA) synthesis were also higher under the two treatments. 12 FAs were detected using gas chromatography-mass spectrometry, among which palmitic acid, oleic acid, and linoleic acid were the main components. EBL5, EBL10, and MJ200 favored the accumulation of soluble sugar, especially in the middle and late stages. The starch concentration in seeds was lower, but it significantly increased after the application of EBL5. Furthermore, our results demonstrated that EBL and MJ enhanced SOD and POD activity while decreased MDA content. We highlighted that EBL and MJ promoted seed development of S. tonkinensis , affected seed chemical compositions and contributed to the accumulation of CF and FA.

The production of selenium-enriched fish contributes to alleviating selenium deficiency for humans. In this study, selenium nanoparticles (SeNPs) comparable in bioavailability to selenomethionine (SeMet), increased SeMet content in O. macrolepis ( Onychostoma macrolepis ) muscle. Additionally, dietary SeNPs significantly enhanced selenocysteine (SeCys 2 ) and methylselenocysteine (MeSeCys) levels in O. macrolepis muscle. The effect of SeNPs on selenium speciation in grass carp muscle was consistent with O. macrolepis results. SeCys 2 and MeSeCys showed antioxidant capacity in HEK293T cells, indicating enhanced health benefits of Se-enriched fish produced using SeNPs. Furthermore, the addition of 0.3 mg/kg SeNPs significantly improved the flesh quality of O. macrolepis by reducing the content of crude fat and heavy metals, as well as increasing the levels of crude protein, eicosapentaenoic acid (EPA), docosahexaenoic acid (DHA), and the ratio of n-3/n-6 polyunsaturated fatty acids (PUFAs). Therefore, selenium-enriched fish produced from SeNPs is a good source for improving human dietary selenium intake.
