The impact of curcumin-loaded nanodroplets on the properties commercial salad dressings was examined. Nanoemulsions were formulated using a plant-based oil (medium chain triglycerides, MCT) and either (Quillaja saponaria, QS) or animal-based (whey protein isolate, WPI) emulsifier. Curcumin-loaded nanoemulsions produced by microfluidization contained small anionic droplets: d32 = 0.28 0.11 μm ζ ...

Studies on the formation of ommochrome pigment granules are very few, despite their generalized occurrence as screening pigments in insect eyes. This is particularly true for ommochrome granules responsible for epidermal coloration. The aims of this study were to characterize the localization of major body pigments in a color changing mimetic spider, Misumena vatia (Thomisidae), and to describe...

# 2002 International Union of Crystallography Printed in Denmark ± all rights reserved A structural study is described of the photoactive yellow protein (PYP) reconstituted with the chromophore derivative 3,4-dihydroxycinnamic acid. The crystal structure of PYP reconstituted with this chromophore at 1.16 AÊ resolution is reported in space group P65. This is the ®rst high-resolution structure of...

Esterification and transesterification of high free fatty acid (FFA) oils to fatty acid alkyl ester (FAAE) by sol-gel entrapped lipase B from Candida antarctica (CalB) and lipase from Burkholderia cepacia were investigated. The optimal conditions for the esterification catalyzed by the immobilized CalB were determined to be 50 °C, 1.7:1 molar ratio of methanol to fatty acid, and 0.36 g of water...

Tomato, as a fresh or processed product, has a high nutritional value due to its content of bioactive components such as phenolic compounds. Few studies describe the effect of processing on antioxidant content and the cancer cell growth inhibition activity. In this study we determined the phenolic and ascorbic acid content of three yellow tomato varieties, before and after thermal processing. M...

Karoowia saxeti was recorded during the lichen field expedition in southern part of Korea in 2006. The lichen was found on the rock surface along coastal line. This species was easily recognized by chemistry (K+ yellow) and the presence of isidia. Thallus was saxicolous, subcrustose, more or less lobate at the center with clearly lobed margins, 2~6 cm broad and pale yellowish green. Thalli lobe...

The feedstock used in our experiment for the production of biodiesel was Yellow Grease. The whole experiment was divided into two parts: Production and Testing. Production involves Transesterification of free fatty acids in yellow grease to form yellow grease alkyl esters. The process of testing involved calculation of the physio – chemical properties, acid value, density, kinematics viscosity ...
