Potato tuber is a highly nutritious, wherein genotype and environmental differences are known to exist in the shape, size and nutritional value of potatoes. Owing to its high consumption, potato could be an ideal carrier of health-promoting phytochemicals. Potato cultivars contain many bioactive lipidic compounds such as fatty acids, glycolipids, phospholipids, sterols, tocols and carotenoids, which are highly desirable in diet because of their health-promoting effects. In the scientific literature, information on the content and profile of bioactive lipidic compounds in potato cultivars are few. The concentration and stability of bioactive lipids are affected by many factors such as genotype, agronomic factors, postharvest storage, cooking and processing conditions. In this review levels and composition of bioactive lipids in terms of lipid classes, fatty acids, phytosterols, tocopherols, and caroteinoids distribution in different potato cultivars including genetically modified potato (GMP) were highlighted and discussed. In addition, factors affecting bioactive lipids levels, stability and health benefits are reviewed. In consideration of potential nutritional value, detailed knowledge on lipids of potato cultivars is of major importance.

Fatty Acids and Bioactive Lipids of Potato Cultivars: An Overview

马铃薯品种中的脂肪酸和生物活性脂质：综述

The essential oil, extracted from the Hmong medicine Blumea balsamifera (L.) DC. (BBO), is a purely natural wound repair agent. Its application has, however, been restricted due to its low solubility and high volatility properties. In this study, we have developed a nanoemulsion formulation to improve the characteristics of BBO. The particle size of the nanoemulsion was normally distributed, and 71% of its range was concentrated between 10-100 nm, with an average particle size of 62.8 nm and an encapsulation rate of 98%. After 7 days of application, the wound healing rate of the BBO nanoemulsion (BBO-NE) group was 1.5 times higher than that of the normal BBO group. Along with histological observations, nanoemulsion formulation has been demonstrated to significantly improve the efficacy of BBO for wound repair. In addition, inflammation-related TLR4, CD14 and IRAK-1 gene transcript levels were significantly reduced after the administration of BBO-NE compared to the BBO group, with downregulation of 47.8%, 35.7% and 57.8%, respectively, while the secretion of pro-inflammatory factors IL-6 and TNF-α was also significantly reduced by 83.8% and 32.7%, respectively, in the nanoformulation administration (BBO-NE) group compared to the BBO group. In contrast, the anti-inflammatory factor IL-10 was significantly increased by 4.2-fold. It was further found that the drug penetration per unit area increased significantly 6.30% to 19.5% at different time points after the application of the BBO-NE compared to the BBO. In conclusion, nano-formulation enhanced the drug penetration of the BBO, reduced inflammatory factors, increased the level of anti-inflammatory factors, and promoted collagen deposition, thereby accelerating wound repair.

Nanoemulsion of the Essential Oil from &lt;i&gt;Blumea balsamifera&lt;/i&gt; (L.) DC. and Its Effect on Trauma Repair

南药油纳米乳剂及其对创伤修复的影响

In this study, tea polyphenols (TP) was added to a soy protein isolate (SPI) to prepare nanoemulsions by ultra-high pressure homogenization (UHPH). The nanoemulsions were characterized by a confocal laser scanning electron microscopy, infrared spectroscopy, dynamic rheometer and size-potential analyzer. The effects of TP on the hydrophobicity, emulsifiability, particle size, potential and antioxidant capacity of the prepared nanoemulsions were investigated. The properties of the nanoemulsions with different concentrations of TP were analyzed. The results indicated that ultra-high pressure homogenization treatment contributed to the formation of the SPI-TP complex that showed higher antioxidant activity. The nanoemulsions with good emulsifying properties and high DPPH scavenging ability at the concentration of TP ranged from 0.15-0.20g / mL. Furthermore, nanoemulsions prepared in this way also had a uniform particle size. Therefore, this nanoemulsions exhibited a good potential to act as an efficient emulsifier.

Structure and Functional Properties of Antioxidant Nanoemulsions Prepared with Tea Polyphenols and Soybean Protein Isolate

茶多酚和大豆分离蛋白制备的抗氧化纳米乳液的结构与功能特性

In 2021, we published three papers related to the anti-inflammatory effects of food ingredients. The present paper reports the effects of vitamin E homologs and sweet basil powder. In these papers, we investigated whether inflammation occurs in the adipose tissue of mice fed a high-fat and high-sucrose diet for 16 weeks. Inflammatory cytokine gene expression was significantly higher in the epididymal fat of the high-fat and high-sucrose diet group than in that of the control diet group. However, the addition of α-tocopherol or δ-tocopherol to the diet could not restrain the inflammation of mice epididymal fats. Thereafter, we investigated the anti-inflammatory effects of α- and δ-tocopherols using the co-cultured cells. Consequently, we clarified that δ-tocopherol inhibited the increase in the gene expressions of inflammatory cytokines. We also examined the effect of sweet basil powder on a similar obese mice model. The final body weight in the high-fat and high-sucrose group that received sweet basil powder was significantly lower than that in the high-fat and high-sucrose diet group. Liver weights were also significantly lower in the high-fat and high-sucrose diet group that received sweet basil powder than in the high-fat and high-sucrose diet group, although adipose tissue weights were unchanged in both groups. Furthermore, sweet basil powder tended to inhibit in lipid synthesis in the mice livers. Therefore, we suggested that sweet basil powder inhibited fatty acid synthesis in mice livers, thereby suppressing liver enlargement, and resulting in body weight loss. Moreover, the gene expression of MCP-1 in the adipose tissue of mice fed a high-fat and high-sucrose diet added with sweet basil powder was significantly lower than that of mice fed a high-fat and high-sucrose diet for 12 weeks. Therefore, sweet basil powder inhibited inflammation onset in the adipose tissue of mice. Taken together, the results suggested that food ingredients, especially vitamin E homologs and sweet basil powder, have anti-inflammatory effects on mice adipose tissue and mice adipocyte-induced inflammation.

Microbial conversion of some natural unsaturated fatty acids can produce polyhydroxy fatty acids, giving them new properties, such as higher viscosity and reactivity. Pseudomonas aeruginosa has been intensively studied to produce a novel 7,10-dihydroxy-8(E)-octadecenoic acid (DOD) from oleic acid and natural vegetable oils containing oleic acid. Recently, the antibacterial activities of DOD against food-borne pathogenic bacteria were reported; however, the action of such antibacterial properties against eucaryotic cells remains poorly known. In this study, we determined the antifungal activities of DOD against Malassezia furfur KCCM 12679 quantitatively and qualitatively. The antifungal activity of DOD against M. furfur KCCM 12679 was approximately five times higher than that of ketoconazole, a commercial antifungal agent. The MIC 90 value of DOD against M. furfur KCCM 12679 was 50 µg/mL. In addition, we confirmed that the antifungal property of DOD was exerted through fungicidal activity.

Gas chromatography (GC) was used to determine the fatty acid (FA) compositions of total lipid, phospholipid (PL), phospholipid subclass (phosphatidylcholine (PC), phosphatidylinositol (PI), phosphatidylserine (PS), phosphatidylethanolamine (PE)), and TAG (triacylglycerol) fractions in male Chondrostoma regium. Percentages of myristic acid (14:0), palmitoleic acid (16:1n-7), oleic acid (18:1n-9), monounsaturated fatty acid (ΣMUFA), linoleic acid (18:2n-6) and linolenic acid (18:3n-3) were found to be higher in TAG than the values determined in PL classes. Palmitic acid (16:0), eicosapentaenoic acid (EPA, 20:5n-3), docosahexaenoic acid (DHA, 20:6n-3) in the PC fraction; 16:0, 20:5n-3, 22:6n-3 in PE; 16:0, stearic acid (18:0), arachidonic acid (AA, 20:4n-6), 20:5n-3, 22:6n-3 in PI; and 16:0, 18:0, oleic acid (18:1n- 9), 22:6n-3 in PS were found to be dominant. In total lipid, the PUFA/SFA ratio was 1.37-1.83; atherogenicity index (AI) was 0.34-0.47 and thrombogenicity index (TI) was found in the range of 0.18-0.22. The n-3/n-6 ratio, which is an important index for nutritional content, was found to be between 5.15 and 11.07. It was discovered that the FA compositions of male C. regium were affected by the reproductive period and season. These findings suggest that fish oil might be a beneficial dietary source for preserving human health.

Glucosylceramide (GlcCer), a major sphingolipid in plants, possesses various food functions, including improvement of intestinal impairments. This study evaluated rice cooking conditions and cultivars based on GlcCer levels transferred into the digestive juice using an in vitro digestion model to investigate the factors related to GlcCer availability. GlcCer levels transferred into the digestive juice were higher in rice gruel than in boiled rice. The GlcCer levels in the digestive juice of boiled rice varied based on the rice cultivar, whereas those in rice gruel had no difference. Thus, GlcCer in rice was not fully utilized via digestion. Further, bioaccessibility was related to the amylose ratio and added water content.
