Lead is a heavy metal considered highly toxic, responsible for causing several health problems as well being extremely harmful to fauna and flora. Given this fact, techniques have been studied the removal of from contaminated water, in which stands out adsorption. In sense, objective study was evaluate potential lead(II) biosorption water by seed husks, seeds pods Moringa oleifera Lam (moringa). Biomass characterized energy-dispersive X-ray spectroscopy, Scanning Electron Microscopy Fourier...

Treatments had no effect (P > .05) fiber, meat composition or in muscle profile. However, diet with oil principle blend led an increase length,...

Anacardium occidentale, known as cashew tree, is widely used in the Amazon. This study aimed to evaluate chemical composition, well biological, physicochemical, antioxidant, and acceptability properties, of essential oil (EO) extracted from leaves dwarf tree (EOLC) Amazonian savanna. The EO was obtained by hydrodistillation fresh frozen leaves, with sample selected due its higher yield. components EOLC were identified GC-MS. Antioxidant activity assessed using DPPH ABTS radicals, values 1.96...

The preservative effect of the addition different essential oils (copaiba and oregano) on meat quality parameters sensorial acceptability was analyzed for fresh ground beef patties over 21 days display. Five treatments were assessed: control (CON) without antioxidants; synthetic additive butylated hydroxytoluene (BHT); 0.05% copaiba oil (CEO); oregano (OEO); or blend 0.025% (BEO). lowest cooking losses greatest tenderness (P <0.05) reached with inclusion presented a more intense chroma...

Abstract BACKGROUND This study evaluated the acceptability (by sensorial and visual analyses) of meat from 40 Nellore heifers (finished in feedlots for 73 days) fed with different diets supplemented essential oils (EOs) an active principle blend. The five tested were: CON – a diet without oil blend (eugenol, thymol, vanillin); ROS rosemary EO; BLE blend; BCL clove EO+ BRC rosemary, EOs + aging time was by consumers. RESULTS Diet affected consumer analysis (meat color). EO showed better...

We evaluated the effects of inclusion copaíba (Copaifera officinalis L.) essential oil at 0.05 and 0.1% as a possible replacement synthetic additive butylated hydroxytoluene (BHT) in sheep burgers during 14 days storage refrigerated display case (4°C). During shelf life days, analyzes antioxidant activity, lipid oxidation, pH, color, cooking loss, texture consumer acceptability were carried out on burgers. The addition showed an effect (P > 0.05), reducing oxidation. Copaiba added 0.05%...

The study aimed to evaluate the effect of supplementation an additive based on plant and spice extracts in broiler chicken diets productive performance, carcass yield, meat quality. 704 male chicks were distributed a completely randomized experimental design with 4 treatment, replicates 44 chickens each. consisted Diet 1: Control diet; 2: diet + antibiotic growth promoters (AGP); 3: vegetable (100 g/ton) 4: (150 g/ton). used carvacrol, cinnamaldehyde, eugenol extracted from oregano,...

Abstract Due to lead (Pb) being highly toxic and harmful living beings, several techniques have been studied aiming at its removal from contaminated water, with great emphasis on the adsorption process. In this sense, objective of study was investigate if chemical functionalization in biosorbents Moringa oleifera pods promotes greater potential process removing aqueous solution. To end, characterization biomass performed by energy dispersive X‐ray spectroscopy, Fourier transform infrared...

For 2160 broilers, were raised from 1 to 42 d of age, was evaluated the consequences microencapsulated blend organic acids and bioactive compounds on dietary supplementation in broilers meat quality consumer acceptance during 200 d. Broilers randomly distributed a completely randomized design with 6 treatments: Negative control (NC): basal diet; Positive (PC): NC+ Zinc bacitracin 15%; B150: NC+150 g/t compounds; B300: NC+300 B450:NC+450 B600:NC+600 compounds. The poultry characteristics...

This study evaluated the use of an edible coating alginate-based with essential oil (cinnamon and marjoram) on quality Wagyu hamburgers (pH, weight loss, cooking texture, color, lipid oxidation antioxidant activity) during 7 days display. Microscopy, FTIR acceptability were also evaluated. Four treatments evaluated: CON –hamburger without coating; ECO –with CIN containing 0.1% cinnamon oil; MAJ marjoram oil. pH samples was maintained throughout storage time (p>0.05). Coatings decreased...

Essential oils (EOs) are natural compounds extracted from plants that exhibit antimicrobial and antioxidant properties. therefore attract interest as additives in the food industry. especially for special populations. In case of children diagnosed with Cerebral Palsy. another factor has to be considered. such consistency food. This study evaluated consumer acceptability infant oregano essential oil by cerebral palsy a questionnaire was applied assess consumption habits profile studied...

The objective of this study was to evaluate the protective effect clove essential oil (Syzygium aromaticum L.) (CEO) as a natural antioxidant and possible substitute for butylated synthetic additive hydroxytoluene in chicken patties with moderate severe myopathies white striping wooden breast. were prepared stored refrigerated exposed light 10 days. meat composition analyzed microstructural properties, lipid oxidation, activity ABTS TPC, instrumental color, diameter reduction, cooking loss,...

The production of unconventional foods such as in vitro meat could be popular interest it reduce the damage to environment and respect welfare animals. However, there are a number barriers limiting factors that appear obstacles before scale meat. Although answer overcome all existing questions, great challenge would acceptance by consumers, introduction new consumption habit, produced laboratory, running into ethical cultural issues. This study presents main difficulties can faced for meat,...

The aim of this study was to evaluate a new packaging system in which the paper covered with solution sodium alginate and cinnamon essential oil (CEO) that used as for burger beef. papers were characterized their physical, optical, mechanical, sorption properties. In addition, burgers evaluated antioxidant activity, lipid oxidation, color difference. total, four treatments developed: Con: without coating; Pad: Pco 0.1: coating added 0.1% CEO; 0.05: 0.05% CEO. analysis thickness showed...

A minimização dos recursos naturais coloca em foco a busca por novas alternativas e técnicas de recuperação águas. Os processos como biossorção apresentam algumas vantagens relação aos convencionais purificação água. substituição compostos sintéticos nos tratamentos água podem apresentar baixo custo, boa biodegradabilidade não agressividade ao meio-ambiente. Entre vários relatados na literatura, Moringa oleífera é identificada um promissor biossorvente, uma vez que tem aliada capacidade...

As sementes de Moringa oleífera têm ganhado destaque como uma alternativa viável agente coagulante em substituição aos sais alumínio utilizados no tratamento água todo o mundo. Uma das desvantagens uso destes coagulantes é devido ao aumento matéria orgânica adicionada à mesma, que pode levar a formação trihalometanos. Assim, este trabalho teve objetivo avaliar potencial da semente desengordurada, aplicada processo coagulação/floculação águas superficiais. A partir integral e desengordurada...

A indústria de produtos lácteos produz elevado volume efluentes com potencial poluidor, assim, visando minimizar os impactos causados pelo descarte inadequado as indústrias realizam a coagulação e floculação associadas coagulantes sintéticos ou naturais, estes que têm demonstrado vantagens em relação aos químicos. Moringa oleifera Lam é coagulante natural extraído das sementes Moringa, planta originária da Índia. Assim, o presente estudo propõe avaliar eficiência do comparação ao químico...
