14. Influence of natural and synthetic carotenoids on the color of egg yolk
ABSTRACT Carotenoids are incorporated into the diet of laying hens in order to modify the yolk color. A natural source of carotenoids in tropical countries is annatto, which could be used in the diets of hens. This study aimed to evaluate the addition of natural (annatto) and synthetic carotenoids to the diet of laying hens (commercial and alternative) and t

15. The Recycling of Sugarcane Fiber/Polypropylene Composites
Mechanical recycling is utilized to reuse waste and obtain other plastic products via the reprocessing of a material in industrial equipment. Natural fiber composites have become more popular in recent years; however, these composites' mechanical behavior remains less well-understood than single polymers’ behavior after recycling. Therefore, the objective

16. Natural additives for poly (hydroxybutyrate - CO - hydroxyvalerate) - PHBV: effect on mechanical properties and biodegradation
In this work, the improvement of mechanical properties in biodegradable materials was obtained through the incorporation of natural and also biodegradable plasticizers and nucleation agents into the PHBV copolymer. PHBV production with different quantities of additives was obtained by extrusion followed by injection. The additives in the copolymer were effic

17. Laboratory comparison of aging characteristics of warm mix asphalts involving natural and synthetic water containing additives
When comparing the aging characteristics of hot and warm mix asphalts from a technical point of view, it can intuitively be expected that a warm mix asphalt would be less subjected to aging-induced failures due to lower application temperatures. Since the side effects of warm asphalt technology should be investigated distinctly. This study addresses the agin

18. Production of gaba (γ - aminobutyric acid) by microorganisms: a review
GABA (γ-aminobutyric acid) is a four carbon non-protein amino acid that is widely distributed in plants, animals and microorganisms. As a metabolic product of plants and microorganisms produced by the decarboxylation of glutamic acid, GABA functions as an inhibitory neurotransmitter in the brain that directly affects the personality and the stress managemen

20. Microbiological and Physico-Chemical Evaluation of Mortadellas Elaborated with Essential Oils and Inoculated with Clostridium perfringens Type A / Avaliações microbiológica e físico-química de mortadelas elaboradas com óleos essenciais e inoculados com Clostridium perfringens tipo A
Clostridium perfringens is a rod-shaped, gram-positive, anaerobic, non-motile, spore-forming and oxygen tolerant bacterium and it is directly associated to food-poisoning. Since the growth of customers interest on natural foods, essential oils are perceived as an alternative for the use of artificial additives as nitrite, diminishing its use. The aim of this

22. Behavior patterns of cows with Charolais or Nellore breed predominance fed diets with plant extract or monensin sodium
The objective of this research was to study the ingestive behavior of feedlot cows fed additives based on plant extracts or monensin sodium. Twenty-four Charolais and Nellore crossbred cows with age and average initial weight of 7 years and 423 kg, respectively, were used. The experimental diets were plant extracts: basal diet + 5 g/animal/day of a natural a

23. Natural antioxidant from yerba maté (Ilex paraguariensis St. Hil.) prevents hamburger peroxidation
The aim of this study was to evaluate whether yerba maté alcoholic extracts at very low concentrations (0.01 and 0.1%), prevent/retard lipid peroxidation in beef hamburgers without impairing sensory acceptability. For this TBARs and hexanal levels, fatty acid profile and cholesterol oxides were evaluated as oxidation parameters in beef hamburgers during 90

Extração, micronização e estabilização de pigmentos funcionais : construção de uma unidade multipropósito para desenvolvimento de processos com fluídos pressurizados / Extractionm micronization and stabilization of functional pigments : construction of multipurpose unit for pressurized fluid process development
The food industry is continuously searching compounds that present physical and chemical properties to improve their products. Most of them are additives with antioxidant properties, colorants or additives with positive effects to human health. Natural additives are always preferred to synthetic compounds. Flavonoids and carotenoids are two of the major func
