Dynamic light scattering (DLS) measurements have been performed at 30 degrees C to see the effects of additives on the microstructure of gemini alkanediyl-alpha,omega-bis(dimethylcetylammonium bromide) surfactants, (Br-, n-C16H33N+Me2-(CH2)s-Me2- N+n-C16H33, Br-, 16-s-16, where s = 4, 5, 6). In pure aqueous solutions, the hydrodynamic diameter, Dh, was found to increase rapidly with geminis in ...

All-polymer solar cells are herein presented utilizing the PBDTTT-CT donor and the P(NDI2OD-T2) acceptor with 1,8-diiodooctane (DIO) and 1-chloronaphthalene (CN) binary solvent additives. A systematic study of the polymer/polymer bulk heterojunction photovoltaic cells processed from the binary additives revealed that the microstructures and photophysics were quite different from those of a pris...

Feed additives are nonnutritive feed ingredients that are not required by swine. In the absence of feed additives in the diet, no deficiency symptoms will result. They may, however, enhance production and profitability under the right circumstances. Feed additives are regulated in the U. S. by the Food and Drug Administration (FDA), and it is very important that the regulations be followed. The...

Background. Metabolic processes of food additives which are “exogenous xenobiotics” are catalysed, primarily, by enzymes located in microsomes of hepatocytes affiliated to P-450 cytochrome superfamily, containing iron. The aim of the study was to investigate the effect of diet composition and selected food additives on the erythrocyte system and iron metabolism in peripheral blood of male rats....

AIM the aim of this study is to measure acceptance of a specific functional food: apple (fruit) leather, based on organoleptic characteristics and to identify consumer types and preferences for natural additives which increase the product's functionality and meet current nutritional needs. MATERIALS AND METHODS a sample of 800 consumers provided an evaluation of apple leather in terms of acce...

We previously developed a new method for estimating intakes of environmental contaminants, called Estimated Ecological Daily Intake (EEDI), which is based on food consumption data. This method accurately estimates the intakes of food additives and contaminants and provides rough estimates of averages and distribution curves for the target population. By this method, we originally considered onl...

We performed an objective evaluation of 39 children whose behaviour was observed by their parents to improve on an artificial food additive free diet and to deteriorate with dietary lapses. Only 19 children completed a double blind placebo controlled challenge study with artificial food colours. In these children food colours were shown to have an adverse effect on a daily Conners' rating of be...

OBJECTIVE To understand the tobacco industry's research on and use of cigarette additives that alter the perception of exposure to environmental tobacco smoke (ETS). DATA SOURCES Internal documents from four websites maintained by the major US tobacco manufacturers and company patents pertaining to the use of ETS altering additives obtained from the US Patent and Trademark Office online datab...

Two experiments were conducted using laboratory mini-silos to study the effect of ensiling and silage additives on fatty acid (FA) composition, including minor or unusual FA, of ryegrass and corn silages. Ryegrass was ensiled for 12 wk with no additives, with the addition of a bacterial inoculant or formic acid. Corn was ensiled for 9 wk without additives, with the addition of a bacterial inocu...

Modern intensive livestock and poultry production has achieved phenomenal gains in the efficient and economical production of high quality and safe animal products and by-products. Furthermore, the overall performance of livestock can be increased by improving nutrients utilization, health status, fertility and efficiency of production. The use of feed additives has been an important part of ac...
