Synthesis and application of a new antibacterial surfactant from apricot kernel oil.

Food emulsifier are mostly prepared from a lipophilic lipid tail with a hydrophilic sugar head. In this study, the lipophilic tail was obtained from apricot kernels, which are food waste, and the hydrophilic head was gluconic acid instead of sugar, in order to draw attention to the non-cyclic poly hydroxyl compounds. Thus, oleic acid of apricot kernel was used as the lipophilic moiety of the prepared surfactant.

Preparation of a Regioselective Quercetin-3-palmitate and Its Using for Boosting Cooking Oil Stability.

Due to over worldwide use of frying oil, and due to its oxidation and deterioration after the usage for short time, huge oil amounts are wasted. So, most attempts are aimed to increase oil stability. Quercetin is a common name for the lipophobic strong natural phenolic antioxidant 2-(3,4-Dihydroxyphenyl)-5,7-dihydroxy-4H-1-benzopyran-4-one.

Synthesis of a new hydrophobic coating film from stearic acid of buffalo fat.

This experiment involved the chemical conversion of pure stearic acid from buffalo adipose tissue to a waxy stearyl stearate, which was subsequently applied as a coating film to extend the shelf life of recently harvested fruits. Fat was extracted from minced adipose tissue using the dry rendering procedure, and it was then characterized. The extracted fat was hydrolyzed into a mixture of free fatty acids and glycerol.

Isolation of Pure Individual Fatty Acids from Chicken Skin Using Supercritical CO Extractor or Cooling Centrifuge.

Chicken skin -a poultry meat industries waste- has been used in this work as a source for the production of pure free fatty acids. Chicken skin fat was extracted using dry rendering method. Physical and chemical parameters of that fat were determined.

Ultraviolet irradiation assisted liquid phase deposited titanium dioxide (TiO)-incorporated into phytic acid coating on magnesium for slowing-down biodegradation and improving osteo-compatibility.

It remains challenging to build up a multifunctional coating onto biodegradable magnesium (Mg) for biomedical use. In this study, a small amount of titanium dioxide (TiO) has been incorporated in situ into phytic acid (PA) coating when it was chemically deposited on Mg substrate targeted to biodegradable implant applications. Ultraviolet (UV) irradiation was utilized in the liquid phase deposition of TiO to improve the quality of coating (PA&TiO-UV).

Synthesis and Application of a New Amphiphilic Antioxidant.

A new amphiphilic antioxidant (tannyl stearate) derived from reaction of tannic acid with stearic acid was synthesized in order to improve tannic acid solubility in lipid materials. This reaction gives many products having different degree of esterification (tannyl mono, di, tri, tetra, penta, hexa, hepta……stearate) which were separated using silica gel column chromatography and tentative identification was carried out using thin layer chromatography (TLC). The intrinsic viscosities (η) were used to differentiate between the different molecular weight of the produced esters.

Utilization of Stearic acid Extracted from Olive Pomace for Production of Triazoles, Thiadiazoles and Thiadiazines Derivatives of Potential Biological Activities.

Olive Pomace was firstly dried, then pomace olive oil was extracted, and the obtained oil was hydrolyzed to produce glycerol and mixture of fatty acids. Fatty acids mixture was separated, this mixture was then cooled, where the all saturated fatty acids were solidified, and then they were filtered off. These saturated fatty acids were identified by GC mass after esterification, and were identified as stearic, palmitic and myristic acids.
