1. Mitigación de la formación de acrilamida en papas fritas tipo chips mediante la adición de antioxidantes fenólicos de Inca muña (Clinopodium bolivianum)
The aim of this study was to evaluate the influence of Inca muña phenolic antioxidants in the reduction of acrylamide (AA) in potato chips. The potatoes were cut into 2 mm thick slices, the addition of antioxidants was evaluated by immersion at atmospheric pressure and by vacuum impregnation (VI) at 80 kPa for 10 min. In both cases, two antioxidant concentr

2. Acrylamide reduces plasma antioxidant vitamin levels in rats due to increased oxidative damage
RESUMO Objetivo A acrilamida é um químico potencialmente neurotóxico e carcinogênico, sendo naturalmente criada durante o processo de aquecimento de alimentos ricos em carboidratos, como batatas fritas e cereais matinais. Dado que o composto pode ser ingerido através do consumo de alimentos, o presente trabalho teve por objetivo investigar o seu efeito

3. Protective effect of citrus lemon on inflammation and adipokine levels in acrylamide-induced oxidative stress in rats
The high exposure to acrylamide (AA) due to smoking and increased consumption of processed and fast foods in recent years, has become one of the health threatening problems. This study examined the effect of lemon juice on inflammation and adipokines in acrylamide-induced oxidative stress in rats. Forty animals were divided into five groups. Toxicity was ind

4. Identification of compounds from chufa (Eleocharis dulcis) peels with inhibitory acrylamide formation activity
Abstract Five compounds were isolated from the peels of chufa (Eleocharis dulcis (Burm.f.) Trin. ex Hensch., Cyperaceae). The chemical structures were determined by various spectroscopic analysis methods, including 1D and 2D NMR, and by comparison with literature data. All compounds were isolated for the first time from the peels of chufa. Compounds orcinol

5. Fotodegradação de hidrogel de poliacrilamida na presença de substâncias químicas para o uso na agricultura
RESUMO Utilizado na agricultura como condicionante do solo, a poliacrilamida, constituinte básico do hidrogel, tem a característica de absorver, por processo físico, água e a estocar para as plantas conforme sua necessidade hídrica. Entretanto, a poliacrilamida sofre degradação de sua cadeia, devido à ação da radiação ultravioleta e de sais prese

6. Evaluation of the embryotoxicity in zebrafish (Danio rerio) of the flocculant and coagulant compounds used for water remediation
Resumo Objetivo: O carreamento decorrente das atividades de mineração atinge corpos d'água, causando contaminação da água e acidificação por metais tóxicos. Como conseqüência, a depleção de oxigênio ocorre, com o desaparecimento de certos organismos bênticos, perdas na biomassa do fitoplâncton e do zooplâncton, e mortalidade de peixes. Rem

7. In Vitro Study Towards Role of Acrylamide-Induced Genotoxicity in Human Lymphocytes and the Protective Effect of L- Carnitine
ABSTRACT Acrylamide (AA), is an important industrial compound, formed during food processing under high temperature. Due to its potential carcinogenic effect, it has been recognized as a human health concern. In this study, we investigated the role of oxidative stress in acrylamide’s genotoxicity and protective role of L- carnitine (LCA) in human lymphocyt

8. Acrylamide replaced by moringa extract in sugar production
Abstract This manuscript showed a new product that can be used in sugar and alcohol production to replace the acrylamide polymer, applied in the juice treatment. This new product is an organic extract obtained from moringa seeds, which present the flocculating protein 2S-Albumin. This biomolecule is added in the decanter together with the limed and heated j

9. Ultrasound-assisted synthesis of polyacrylamide-grafted sodium alginate and its application in dye removal
Abstract A polymeric adsorbent based on sodium alginate (SAG) grafted with polyacrylamide (PAM) (SAG- g-PAM) was synthesized using an ultrasound-assisted method. The addition polymerization was carried out with ammonium persulfate as the initiator, at different acrylamide (AM) concentrations. The SAG-g-PAM copolymers were evaluated by FTIR and 13C NMR spect

10. THE USE OF POLYSACCHARIDES EXTRACTED FROM SEED OF Persea americana var. Hass ON THE SYNTHESIS OF ACRYLIC HYDROGELS
This paper reports the use of polysaccharides extracted from seed of Persea americana var. Hass in the synthesis of acrylic hydrogels. The effects of the chemical composition (acrylamide/acrylic acid), the concentration of crosslinking agent (glycerol diacrylate) and the type of initiation (redox, photoinitiation) of the hydrogels were evaluated with and wit

11. Radiation-induced Changes in the Electrophoretic Profile of Serum Albumin
ABSTRACT Albumin protein profiles were investigated in electrophoresis system in relation to the whole body exposition to the radiation. Two groups of rats Wistar were set up as the control (CG) and the irradiated one (IG). The IG was exposed to Co-60 at a dose of 5 Gy. After a 72-hour exposition, 300 μL of blood was collected in the inferior vena cava, ren

12. Bioethanol production with different dosages of the commercial Acrylamide polymer compared to a Bioextract in clarifying sugarcane juice
ABSTRACT One of the most important steps is to clarify the juice, which are added synthetic polymer acrylamide base, aiming the fast settling of impurities present in the juice. However, this input is expensive and may have carcinogenic and neurotoxic actions to humans. The search for new natural flocculants that have similarity with the commercial product i
