The solidification behavior of cocoa butter from the melt phase was examined during two different types of thermal treatment : simple cooling (60→29°C) and cooling/heating (60→22→30°C).Triacylglycerol composition and polymorphic modified samples were determined. The crystals formed by simple cooling were a mixture of Form V and Form VI of cocoa butter. But only the Form V could be found in crystals obtained by the cooling/heating. These crystals were filtered out and what appeared to be fat blooming of the solidified samples of residual melt was examined. The fat blooming was found in solidified fat after the filtration of simple cooling crystals less than 1 μm in size and in cooling/heating cystals 0.22 μm in size. The addition of 0.2 % of the seed crystals of cocoa butter with Form VI increased the rates of solidification and no fat blooming was observed.

The rapid and simultaneous separation of triacylglycerol (TAG) enantiomers and positional isomers was achieved using chiral high performance liquid chromatography (HPLC). TAGs composed of two fatty acids, which were both saturated (P: palmitic acid or S: stearic acid) and unsaturated (O: oleic acid or L: linoleic acid; e.g., sn-PPO/sn-OPP/sn-POP: 1,2-dipalmitoyl-3-oleoyl-sn-glycerol/1-oleoyl-2,3- dipalmitoyl-sn-glycerol/1,3-dilpalmitoyl-2-oleoylglycerol), were resolved into three peaks using CHIRALPAK IF-3 without recycling on the HPLC system. For example, the mixture of sn-PPO/sn-OPP/sn-POP was resolved in 30 min, although it took 150 min to resolve sn-PPO/sn-OPP using CHIRALCEL ODRH in a previous study using a recycling HPLC system. This novel chiral HPLC method was applicable for the separation of other TAG isomers, including sn-OOP/sn-POO/sn-OPO, sn-PPL/sn-LPP/sn-PLP, sn-LLP/sn-PLL/sn-LPL, sn-SSO/sn-OSS/sn-SOS, sn-OOS/sn-SOO/sn-OSO, sn-SSL/sn-LSS/sn-SLS, and sn-LLS/snSLL/sn-LSL. For TAGs composed of three fatty acids containing both saturated and unsaturated fatty acids, the POL isomers were not sufficiently separated but the PSO and SOL isomers were partially separated into several peaks. Their elution order could be estimated by the fragment ions generated in the ion source of the mass spectrometer. However, TAGs consisting of only saturated or unsaturated fatty acids (e.g., sn-PSP/sn-PPS/sn-SPP and sn-OLO/sn-OOL/sn-LOO) were not separated. This novel chiral HPLC method is especially applicable for the analysis of TAG composition of semi-solid fats such as palm oil.

Ginkgo biloba extract (GBE) is widely used as herbal medicine. Preventive effect of GBE against dementia, including Alzheimer’s disease, has been reported. The bioactive compounds in GBE that impart these beneficial effects, flavonoids and terpene lactones, have poor bioavailability. Our previous study found distribution of bioactive compounds of sesame extract in mice brain after mixing it with turmeric oil. Here, we evaluate the distribution of bioactive compounds of GBE by combining it with the mixture of sesame extract and turmeric oil (MST). The content of terpene lactones in mice serum was significantly increased in a dose-dependent manner after administration of GBE. However, the contents of terpene lactones in mice brain were not significantly changed. Concentration of ginkgolide A in mice brain increased significantly when GBE was co-administrated with MST than when GBE was administered alone. These results suggest that MST may be effective in enhancing the bioavailability of ginkgolide A in GBE.

1,2-Alkanediol exhibits antibacterial activity against several bacteria and yeast. However, few studies have reported antimicrobial tests on skin microbiome. Bacterial microbiome on the skin surface include Staphylococcus aureus (S. aureus), which causes rough skin and inflammation in atopic dermatitis and Staphylococcus epidermidis (S. epidermidis), which enhances innate immunity. In this study, the minimal inhibitory concentration (MIC) was evaluated for 1,2-alkanediol comprising 4–12 carbon atoms against S. aureus and S. epidermidis. 1,2-Alkanediol comprising 6–12 carbon atoms exhibited antimicrobial activity against both species of Staphylococcus. The antibacterial activity depended on the alkyl chain length. In addition, the minimum bactericidal concentration (MBC) on agar was evaluated for 1,2-alkanediol comprising 6–12 carbon atoms. 1,2-Octanediol and 1,2-decanediol exhibited significant bactericidal activity.

In the present work, a high-performance liquid chromatographic method coupled with mass spectrometry (HILIC-HPLC /ESI-MS) was used for the characterization and the quantification of glycerophospholipids (GPLs) classes and their molecular species in three genetically different Tunisian apricot cultivars (bitter, sweet and semi-sweet apricots). The application of the proposed method to the analysis of apricot oil allowed to separate and identify 74 molecular species of GPLs. Phosphatidylcholine (PC) class was found to be the most abundant GLPs in the three seed oils (38.6-62.4%) especially in bitter apricot, followed by phosphatidylinositol (PI) and phosphatidylethanolamine (PE) classes with values of 8.3-38.9% and 1.7-25.4% respectively. Phosphatidic acid (PA), phosphatidylglycerol (PG) and lysophosphatidylcholine (LPC) compounds were minor ones with maximums of 11.3%, 9.8% and 9.2% respectively. The results we obtained for the three Tunisian apricot seed varieties clearly indicate that the phospholipids of Tunisian apricot are of great interest. In fact, the high content of phosphatidylcholine (PC) determines it as a suitable and valuable source for obtaining corresponding phospholipids concentrates.

Bacterial flora on the skin surface contains Staphylococcus aureus (S. aureus) and Staphylococcus epidermidis (S. epidermidis) which causes rough skin and atopic dermatitis and enhances innate immunity, respectively. In this study, minimum inhibitory concentration (MIC) was evaluated for six saturated fatty acids and two unsaturated fatty acids against S. aureus and S. epidermidis. The antimicrobial behavior in the liquid medium was categorized into three groups. The first was the selective antibacterial activity group comprising myristic acid (C14:0 fatty acid), palmitoleic acid (C16:1 fatty acid), and oleic acid (C18:1 fatty acid) and preferentially displayed antimicrobial activity for S. aureus (group 1). C16:1 fatty acid displayed high antimicrobial activity only for S. aureus. The second was the non-selective antibacterial activity group which displayed antibacterial activity for both Staphylococci (group 2). Caprylic acid (C8:0 fatty acid), capric acid (C10:0 fatty acid), and lauric acid (C12:0 fatty acid) comprised group 2. The third was the non-antibacterial activity group which did not show significant antimicrobial activity (group 3). Bactericidal activities were confirmed for C12:0 fatty acid and C16:1 fatty acid by evaluating the minimum bactericidal concentration (MBC) on the agar medium. C12:0 fatty acid displayed non-selective bactericidal behavior against S. aureus and S. epidermidis when the fatty acid concentration was above 250 μg mL–1. These findings suggest that C16:1 fatty acid has the potential to be used as a detergent in skin care and medical products because it can selectively kill only S. aureus.

This investigation was carried out to study the effect of some detergents and surfactants on the early stages of growth of radish, chinese cabbage and rice in hydroponic culture.Based on the results and the known highest levels of major anionic surfactants present in river waters, it could be estimated that these are not capable of inhibiting growth of these plants.The threshold level of toxicity on test materials for these plants was different from that of the animals tested.Plants treated with sodium chloride, soybean sauce and phosphorous-containing detergent showed better growth compered to the control.

Fatty acid calcium salt is a high melting point powder excellent in lubricity and water repellency and is often used as a cosmetic raw material. We have shown that several calcium salts of fatty acids have high selective bactericidal activity against Staphylococcus aureus and Propionibacterium acnes and low bactericidal activity against Staphylococcus epidermidis. In this study, we evaluated the influence of pH on the bactericidal behavior of calcium laurate, and showed that under acidic conditions it shows higher bactericidal activity against both bacteria but selectivity becomes lower. This finding is useful for designing skin cleansers and makeup cosmetics containing lauric acid.

Generation of singlet oxygen by solar ultraviolet (UV) radiation causes acute inflammatory responses in the skin. Accumulation of singlet-oxygen-quenching antioxidants in the skin can suppress this photo-oxidative stress. This study evaluated the effect of dietary xanthophylls from red paprika fruit extract on UV-induced skin damage. A randomised double-blind placebo-controlled parallel group comparison study involving 46 healthy volunteers was performed. The minimal erythema dose (MED) of each individual was determined prior to the study. A capsule containing paprika xanthophylls (9 mg) or a placebo was administered daily for 5 weeks. The MED, minimal tanning dose (MTD), skin physiology parameters (skin color, hydration, and barrier function), and facial skin physiology parameters were evaluated at weeks 0, 2, and 4. The MED of the verum group at 2 and 4 weeks after administration was significantly higher than that of the placebo group. At 4 weeks, the suppression of UV-induced skin darkening by the verum diet was significantly greater than that of the placebo. There were no significant differences in facial skin parameters between the verum and placebo groups. Our results indicate the efficacy of dietary paprika xanthophylls in suppression of UV-induced skin damage.

Diarrhea often occurs during enteral nutrition. Recently, several reports showed that diarrhea improves by adding egg yolk lecithin, an emulsifier, in an enteral formula. Therefore, we evaluated if this combination could improve diarrhea outcomes. We retrospectively investigated the inhibitory effects on watery stools by replacing a polymeric fomula with that containing egg yolk lecithin. Then, we investigated the emulsion stability in vitro. Next, we examined the lipid absorption using different emulsifiers among bile duct-ligated rats and assessed whether egg yolk lecithin, medium-chain triglyceride, and dietary fiber can improve diarrhea outcomes in a rat model of short bowel syndrome. Stool consistency or frequency improved on the day after using the aforementioned combination in 13/14 patients. Average particle size of the egg yolk lecithin emulsifier did not change by adding artificial gastric juice, whereas that of soy lecithin and synthetic emulsifiers increased. Serum triglyceride concentrations were significantly higher in the egg yolk lecithin group compared with the soybean lecithin and synthetic emulsifier groups in bile duct-ligated rats. In rats with short bowels, the fecal consistency was a significant looser the dietary fiber (+) group than the egg yolk lecithin (+) groups from day 6 of test meal feedings. The fecal consistency was also a significant looser the egg yolk lecithin (–) group than the egg yolk lecithin (+) groups from day 4 of test meal feeding. The fecal consistency was no significant difference between the medium-chain triglycerides (–) and egg yolk lecithin (+) groups. Enteral formula emulsified with egg yolk lecithin promotes lipid absorption by preventing the destruction of emulsified substances by gastric acid. This enteral formula improved diarrhea and should reduce the burden on patients and healthcare workers.

Shrimp (Acetes sp.) was mixed with salt in a ratio of 3:1 and allowed to ferment at room temperature (28-30°C). From the shrimp paste samples collected at the initial (1 day) and end (10 days) of fermentation, 85% ethanol extracts were prepared for their antioxidative assays. Both extracts exhibited high free radical scavenging property against 1,1 diphenyl 2-picrylhydrazyl and suppressed peroxidation of methyl linoleate initiated by 2,2′azobis 2-amidinopropane dihydrochloride. These antioxidative activities, however, did not change significantly during fermentation for 10 days, thus suggesting that the observed antioxidative activities could have mainly due to original antioxidants present in shrimp but not to its fermentative products. The salt-fermented shrimp samples contained large amount of polyunsaturated fatty acids including EPA and DHA, although the polar lipids like phospholipids were hydrolyzed during fermentation to produce the corresponding amount of free fatty acids. In addition, free amino acids of the shrimp sample significantly increased during the fermentation and could be responsible for the unique flavor of salt-fermented shrimp paste. Since the salt-fermented shrimp paste was found to obtain potent antioxidative substances and large amount of EPA, DHA, and amino acids, it is expected to act as an effective antioxidant in our body and to be a good source of these nutrients.

Authors could make clear that the total unsaturation of α, β-unsaturated organic acids (crotonic acid, acrylic acid, methacrylic acid and maleic acid) can be estimated quickly by the method using aqueous solution of bromine chloride prepared by acidifying the aqueous solution of potassium bromate and potassium bromide with hydrochloric acid.The iodine value of fatty materials containing isolated double bonds (oleic acid, methyl erucinate, olive oil, rape seed oil and sesame oil), and water insoluble acid samples such as cinnamic acid containing α, β-ethylene linkage were measured by the method using the solution of bromine chroride in glacial acetic acid. The results obtained in the analysis by the method were essentially similar to that of the Wijs method, except the results in the case of cinnamic acid. There is a remarkable agreement between the estimated iodine value of cinnamic acid and its theoretical value.
