An analytical method using high performance liquid chromatography with UV detection (HPLC‑UV) (method A) was used for simultaneous determination of total amounts triacylglycerides, diacylglycerides, monoacylglycerides and fatty acid methyl esters in alcoholysis different oil (cotton, canola, sunflower, corn soybean) samples. Analyses were carried out at 40 °C 20 min a gradient methanol (MeOH) 2-propanol-hexane 5:4 (v/v) (PrHex): 100% MeOH 0 min, 50% PrHex 10 maintained isocratic elution min....
Situations including premature infants, or those in which there is a rejection to breastfeeding, require the use infant formulas for total partial replacement of human milk. The objective this study was determine lipid content and identify profile formulas. Samples were collected from ten different formulas, used as substitute breast milk at Maternal Child Hospital Brasilia. sample consisted pool samples 10 mature donors bank University analyzed. experiment conducted randomized block design,...
Sorghum is used to provide good quality gluten-free products due phytochemicals and low glycemic index (GI). This study aimed determine the chemical composition, antioxidant activity capacity, insulinemic responses of (GF) sorghum bread. GF bread samples were produced with three different genotypes. The analyzed for resistant starch dietary fiber content; by ORAC; capacity FRAP; GI; responses. double-blind, crossover, randomized clinical trial was conducted 10 healthy men aged 28.0 ± 4.9...
A pesquisa teve como objetivo realizar análise da qualidade físico-química, microbiológica e presença de resíduos antibióticos em leite não orgânico pasteurizado no Distrito Federal, através métodos laboratoriais, comparar os resultados com levantamentos feitos na literatura para o orgânico. Foram determinadas as características físico-químicas, microbiológicas 131 amostras orgânico, período janeiro a dezembro 2018. Verificou-se que uma, dentre sete marcas avaliadas, apresentou fora dos...
Pequi (Caryocar brasiliense Camb.), a typical fruit of Brazilian Cerrado, is well known in regional cookery and used folk medicine to treat various illnesses. Mass spectrometry chromatographic methods have identified the organic composition pequi pulp; however, NMR spectroscopy for first time characterize nutritional components aqueous-ethanolic extracts. This spectroscopic technique determined triacylglycerols fraction, which constituted mainly by oleate palmitate esters, detected...
The present work aimed to evaluate the decomposition kinetics of ozone in aqueous media with Brazil nuts. It also intended investigate potential ozonation for inactivating Aspergillus flavus, and determine changes nut color crude oil lipid profile. To do so, an inlet concentration 13.0 mg L−1, at a flow rate 1 L min−1 25°C, was adopted. For process, distilled sterilized water pH levels 8.1, 7.1, 3.0 used. second-order kinetic model fit residual data. effect on A. treatment performed 120 min...
The demand for gluten-free products is rising, but their production with similar quality as gluten counterparts challenging. This study aimed to develop bread samples using different concentrations of Amorphophallus konjac flour (0%, 12.5%, 25%, 37.5%, and 50% the total content) evaluate nutritional physicochemical properties. Proteins, lipids, carbohydrates, moisture, ash content, fibers, resistant starch, firmness, specific volume, color were evaluated official methods. Protein varied from...
Meat is a source of protein widely consumed by the population in many countries due mainly to nutritional aspects, sensory characteristics, and cultural aspects. The meat cooking preparation can promote significant changes meat's chemical composition physical characteristics. Such transformations impact both acceptance product consumers' health. Due different thermal processes altering physical-chemical characteristics meat, present study aimed evaluate physicochemical fillet steak submitted...
O conhecimento da divergência genética disponível em um conjunto de genótipos é grande importância programas melhoramento, por evitar recombinações gênicas semelhantes, com consequente aumento expressão heterótica híbridos e ganhos genéticos gerações segregantes. Objetivou-se caracterizar morfoagronômicamente 23 batata-doce do banco ativo germoplasma mantido na Embrapa Hortaliças; utilizar estas características para avaliar a variabilidade entre os materiais pela aplicação dos métodos...
This study aimed to develop an araticum (Annona crassiflora) juice supplemented with a probiotic strain L. paracasei LBC-81, and evaluate the viability during refrigerated storage period under in vitro gastrointestinal conditions. Three juices formulations were elaborated containing 20 % (F1), 30 (F2) 40 (F3) of pulp, without LBC-81. Changes physiochemical properties also evaluated. The three 28 days was significantly greater (P < 0.05) than recommended minimum (6 log CFU mL−1) for product...
The Human Milk Bank undergo human milk to pasteurization, followed by storage in a freezer at -18° C for up six months thus keep available the stocks of this product maternal and infant hospitals. objective study was evaluate effects processing on lipid fraction milk. A sample obtained from donor subdivided into ten sub-samples that subjected following treatments: LC = raw milk; T0 after pasteurization; T30 pasteurization freezing 30 days; T60 freeze 60 days, so every days until T240 240...
This study aimed to evaluate the proximate composition of quinoa grown in central plateau Brazilian Cerrado during summer and winter periods. Grains Kancolla, BRS Piabiru, Syetetuba varieties were evaluated for parameters such as moisture, dry matter, ash, protein, lipids, carbohydrates, crude fiber, calcium, magnesium, phosphorus, sulfur, potassium. It was observed that grains varies depending on cultivation period, with higher averages summer. However, both periods, than those reported...
Studies report that the frying process causes chemical changes in altering its composition, causing unpleasant flavor, very hard and dark fried food surface, an excess of oil absorbed, among others. Deep-frying samples were collected from four randomly chosen services every other day for 10 days. Acidity, peroxide, iodine values measured; lipid profiles determined by gas chromatography. Esterified stored at -18°C. The statistical software used was SAS, version 2.0, 5 % significance level....
