Omega-3 rich fish oils are extremely labile, thus requiring control of oxidation and off flavor development. A recently proposed emulsification method, layer-by-layer (LbL) deposition, was found to be a plausible method to enhance the characteristics of bioactive ingredients, especially lipids. The present work was designed to test the possibility of enhancing the uptake and utilization of omega-3 fatty acids present in fish oil. The bioavailability of nano-emulsified fish oil was monitored in terms of intestinal absorption as well as skin permeability by using the everted intestinal sac model and Franz cell model. The skin permeability and intestinal absorption characteristics was significantly improved by LbL emulsification with lecithin/chitosan/low methoxypectin. Multilayer encapsulation along with nano-emulsification can be a useful method to deliver biologically active lipids and related components, such as fish oil. The protective effect of this tool from lipid oxidation still needs to be verified.

The present study aimed to explore the potential of macroalgal hydrolysate to serve as an economical substrate for the growth of the oleaginous microbes Aspergillus sp. SY-70, Rhizopus arrhizus SY-71 and Aurantiochytrium sp. YB-05 for lipid and DHA production under laboratory conditions.

Based on the observation that urea, water, and ethyl esters (EE) can form gypsum-like mixtures, this study explored the feasibility of employing water as a solvent for urea in the urea complexation method to enrich n-3 polyunsaturated fatty acids with docosahexaenoic acid (DHA)-containing ethyl esters (DHA- EE) from Crypthecodinium cohnii as the material. Under the conditions of a urea/DHA-EE ratio of 3, a water/DHA-EE ratio of 0.75, a mixing temperature of 65℃, and a cooling temperature of 20℃, a concentrate containing over 90% DHA was achieved.

Exaggerated neuronal excitation by glutamate is a well-known cause of excitotoxicity, a key factor in numerous neurodegenerative disorders. This study examined the neurotoxic effect of monosodium glutamate (MSG) in the brain cortex of rats and focused on assessing the potential neuroprotective effects of omega-3 polyunsaturated fatty acids (ω-3 PUFAs). Four groups of adult male rats (n = 10) were assigned as follows; normal control, ω-3 PUFAs (400 mg/kg) alone, MSG (4 mg/g) alone, and MSG plus ω-3 PUFAs (4 mg/g MSG plus 400 mg/kg ω-3 PUFAs).

Background: The upregulation or delay of acute inflammation at any stage limits fat graft survival. Active endogenous inflammation resolution mechanisms and mediators are novel therapeutic tools for inflammation. This study explored the effects of supplementation of omega-3 polyunsaturated fatty acids (PUFAs) deriving specialized proresolving mediators (SPMs) on postoperative inflammation and graft survival in vivo.

Global high consumption of fried potatoes is driven by appealing taste and edible convenience. However, the occurrence of Maillard reaction hazardous products (MRHPs) and joint control recipes have scarcely been concerned. We aim to reveal and predict how fish oil treatment for potato slices reduces simultaneous formation of typical MRHPs in air-based thermal processed potato chips.
