Nanoemulsions could increase the bioavailability of lipophilic compounds. In this study, nanoemulsions were obtained by high pressure homogenization and ultrasonication using capsaicin (oleoresin capsicum) (2 g/100g) in the oil phase and Tween 80 (2 g/100g), glycerol (0-50 g/100g) in the aqueous phase at pH 7.4 and 3.8. Mean droplet sizes below 65 nm were obtained with ultrasonication. Translucent nanoemulsions with minimum 79% efficiencies were obtained with high pressure homogenization. Pressurized nanoemulsions reduced Staphylococcus aureus and Escherichia coli population up to 5.89 and 2.79 log respectively at pH 7.4. The addition of glycerol resulted in almost transparent, bright red colored nanoemulsions. Therefore, capsaicin nanoemulsions showing good antimicrobial activity could be obtained by high pressure homogenization, whereas ultrasonication mostly helped to improve physical properties such as particle size and color.

EFFECT OF MICROWAVE PROCESSING ON WATER SOLUBLE VITAMINS: KINETIC PARAMETERS
Ökmen, Zinet Aytanga; Bayındırlı, Alev (1999-01-01)
The effects of microwave processing on water soluble vitamins (ascorbic acid, niacin, thiamin, and riboflavin) were determined. The kinetic parameters of vitamin degradation reactions for microwave heating were determined for model vitamin systems. The degradation reactions were found to be first-order reactions. The kinetic parameters at different temperatures were also determined.
Effects of Bentonite Combinations and Gelatin on the Rheological Behaviour of Bentonite – Apple Juice Dispersions
Dik, Tunay; Özilgen, Mustafa (Elsevier BV, 1996-11)
Rheological behaviour of bentonite – apple juice suspensions were experimentally determined at 25°C, within the shear rate range of 4.3 to 43.1 s−1with 0.90, 1.33 and 2.66 g/L bentonite mixtures and 0 to 0.25 g/L (on dry basis) gelatin concentrations. The mixtures consisted of 100%, 80%, 60%, 40% 20% and 0% Ca-bentonite and balance Na-bentonite combinations. The experimental data were described with the power law as τ =Kγ.1.56. The consistency index was related to the calcium, sodium and gelatin concentrati...
Inhibition of mackerel (Scomber scombrus) muscle lipoxygenase by green tea polyphenols
Banerjee, Sreeparna (Elsevier BV, 2006-01-01)
The high polyunsaturated fatty acid content of oily fish such as mackerel (Scomber scombrus) makes it particularly susceptible to oxidative degradation. We have shown previously the presence of lipoxygenase (LOX), a lipid oxygenase, in mackerel muscle. In the current study, commercially available green tea polyphenols were shown to effectively inhibit the LOX activity of mackerel muscle. EGCG (epigallocatechin gallate) was the strongest inhibitor tested with an IC50 (concentration for half maximal inhibitio...
Evaluation of hemicellulose as a coating material with gum arabic for food microencapsulation
Tatar, Feyza; Tunc, Merve Tugce; DERVİŞOĞLU, MUHAMMET; Çekmecelioğlu, Deniz; KAHYAOĞLU, TALİP (Elsevier BV, 2014-03-01)
In this study, hemicellulose-based coatings were assessed for use in microencapsulated fish oil. The fish oil emulsions were prepared using the solutions of gum arabic (GA), gum arabic-hemicellulose (GA-HC) and hemicellulose (HC) as the coating materials, amended with maltodextrin as a cheap filler material. The fish oil was then encapsulated with these emulsions using the spray drying method. The effects of the hemicelluloses on the emulsions and the formed microcapsules were evaluated by physical and chem...
Investigation of lipid-derived formation of decadien-1-amine, 2-pentylpyridine, and acrylamide in potato chips fried in repeatedly used sunflower oil
Karademir, Yesim; GÖKMEN, VURAL; Öztop, Halil Mecit (Elsevier BV, 2019-07-01)
This study aimed to investigate lipid derived formations of decadien-1-amine, 2-pentylpyridine, and acrylamide in potato chips during frying. 2,4-Decadienal, a lipid derived carbonyl, was monitored in repeatedly used sunflower oil at different thermoxidation levels (0, 6, 12, 18, 24 h at 180 degrees C), and in potato chips prepared in. Formations of decadien-1-amine and 2-pentylpyridine were shown for the first time in potato chips. Frying oil had the highest concentration of 2,4-decadienal after thermal ox...
