“…The first reason is that the protein charge at pH 7 is much lower than at pH 3. This also could be attributed to the replacement of little undigested protein by bile salts at the interface [ 38 ]. Furthermore, no significant difference was found in ζ-potential values in the end of the intestinal digestion for these three protein-coated emulsions ( p > 0.05, −95.47 ± 1.18 mV, −89.93 ± 5.36 mV, and −97.23 ± 2.87 mV for WPI-, SPI-, and SC-coated emulsions, respectively).…”

α-Tocopherol has been widely used in medicine, cosmetics, and food industry as a nutritional supplement and antioxidant. However, α-tocopherol showed low bioaccessibility, and there is a widespread α-tocopherol deficiency in society today. The preparation of oil-in-water emulsions with high safety and low-calorie property is necessary. The aim of this research was to investigate the effects of different protein emulsifiers (whey protein isolate (WPI), soy protein isolate (SPI), and sodium casein (SC)) on the properties of emulsions delivery system, and diacylglycerol (DAG) was picked as a low-accumulated lipid. The interfacial changes, microstructural alterations, and possible interactions of the protein-stabilized DAG emulsions were investigated during the in vitro digestion. The results show that different proteins affect the degree of digestibility and α-tocopherol bioaccessibility of the emulsions. Both WPI- and SPI-coated emulsions showed good digestibility and α-tocopherol bioaccessibility (77.64 ± 2.93%). This might be due to the strong hydrolysis resistance of WPI (β-lactoglobulin) and the good emulsification ability of SPI. The SC-coated emulsion showed the lowest digestibility and α-tocopherol bioaccessibility, this might be due to the emulsification property of hydrolysis products of SC and the potential interaction with calcium ions. This study provides new possibilities for the application of DAG emulsions in delivery systems.

“…Woody oil plants, which have a small footprint, have the advantage of their high oil output. In recent years, as the new woody oil plant, Idesia polycarpa has gradually caught the attention of researchers because of its high oil yield and nutritive values [ 2 ].…”

“…It is regarded as the “oil bank of trees” due to its high lipid content and oil yield, with a dry base oil content of 26.26% for the seeds and 43.6% for the pulp and an output of 2.25–3.75 tons of oil per hectare [ 6 ]. The oil extracted from I. polycarpa has been used as an edible oil in some provinces of China for hundreds of years and has proven safe for consumption based on toxicological tests and health surveys of people who consume it [ 2 ]. In addition, the leaves of the plant have been known to have hemostatic properties, the seeds have been employed as an insecticide, and the extraction of the fruits has the potential for anti-obesity [ 7 , 8 ].…”

Idesia polycarpa pulp oil (IPPO) has the potential to become the new high-quality vegetable oil. The chemical parameters, fatty acid composition, bioactive ingredients, and antioxidant capacity of five Chinese regions of IPPO were studied comparatively, with significant differences among the regions. The oils were all abundant in unsaturated fatty acids, including linoleic acid (63.07 ± 0.03%–70.69 ± 0.02%), oleic acid (5.20 ± 0.01%–7.49 ± 0.03%), palmitoleic acid (4.31 ± 0.01%–8.19 ± 0.01%) and linolenic acid (0.84 ± 0.03%–1.34 ± 0.01%). IPPO is also rich in active substances such as tocopherols (595.05 ± 11.81–1490.20 ± 20.84 mg/kg), which are made up of α, β, γ and δ isomers, β-sitosterol (1539.83 ± 52.41–2498.17 ± 26.05 mg/kg) and polyphenols (106.77 ± 0.86–266.50 ± 2.04 mg GAE/kg oil). The free radical scavenging capacity of IPPO varies significantly depending on the region. This study may provide important guidance for the selection of Idesia polycarpa and offer insights into the industrial application of IPPO in China.

“…Idesia polycarpa fruit extract isolated a new compound, Idesolide, with a novel spiro structure of tetrahydrobenzodioxole (Kim et al, 2005) determined by single crystal X-ray experimental NMR, and MS spectroscopy significantly reduced lipopolysaccharide-induced free radical nitric oxide production in BV2 microglia. The production of nitric oxide, which is involved in a variety of biological functions including pathogenic inflammation and cell proliferation and differentiation (Jung et al, 2010), was demonstrated by Xiang et al (2023), who performed in vitro lipid digestion of Idesia polycarpa and confirmed that it is highly lipolytic, second only to olive oil, as a nutritious and easily digestible vegetable oil. These studies have uncovered the potential applications of Idesia polycarpa fruits as food, oil, and natural active products.…”

Idesia polycarpa is a good source of high-quality vegetable oil and can potentially alleviate pressure on the supply of edible oil. Exploring Idesia polycarpa could enrich the world’s food and oil resources and make up for the shortage of vegetable oil types and production. Here, 15 varieties of wild Idesia polycarpa from major wild Idesia polycarpa resource belts in the middle and upper reaches of the Yangtze River in China were investigated to elucidate the quality and antioxidant activity of wild Idesia polycarpa fruits to tap the potential exploitation capacity of Idesia polycarpa. In this study, wild Idesia polycarpa varieties with high oil quality and antioxidant activity were screened by the comprehensive evaluation of 42 indexes including oil content, dry basis white grain weight, fatty acids, tocopherols, total flavonoids, and minerals, as well as comparisons of free radical scavenging of 2,2′-azino-bis (3-ethylbenzothiazoline-6-sulfonic acid (ABTS)) and 1,1-diphenyl-2-picrylhydrazyl (DPPH). The result showed the quality characteristics of 15 wild Idesia polycarpa: oil (MN:29.21/100 g), dry basis white grain weight (MN:17.32 g), total flavonoids (MN:27.27 RE/kg), total polyphenols (MN:159.63 GAE/kg), tocopherols [MN:356.10 mg/kg (α-tocopherol (MN:284.96 mg/kg), γ-tocopherol (MN:50. 20 mg/kg), β-tocopherol (MN:9.54 mg/kg), and δ-tocopherol (MN:11.40 mg/kg)], total mineral content (MN:25653.44 mg/kg), and fatty acids [MN:20.89/100 g (70.42% polyunsaturated fatty acids (MN:14.63/100 g), 20.29% saturated fatty acids (MN:4.25/100 g), and 9.29% monounsaturated fatty acids (MN:2.01/100 g)]. Correlation analysis revealed that flavonoids, C16:0, C18:1n9c, C18:2n6c, polyphenols, α-tocopherol, δ-tocopherol, and Ca were significantly correlated with DPPH and ABTS. Cluster analysis and principal component analysis classified the 15 wild samples into three clusters, with the first cluster represented by H8, H6, and H9 being the optimal sample as a woody oilseed crop, the second cluster represented by H10, H 12, and H11 being the optimal sample for functional oil development, and the rest could be selected with emphasis when conducting certain characteristic product development. The excellent lipids and rich nutritional and antioxidant properties suggest that Idesia polycarpa will be a new direction for the development of edible oil resources in the future.
