In recent years, several studies have been developed to understand the impact of fermentation on final quality coffee and indicated that postharvest processing could be a determinant quality. However, trend has appeared as scientific counterpoint, indicating interactions between soil, fruit, altitude, slope exposures with respect Sun are important behavior microbiome in coffee. Studies microbiota addressed its role during process, however knowledge indigenous microorganisms harbored fruits...
Coffee beverage presents unique organoleptic characteristics of aroma and taste. These sensory attributes depend on the chemical composition brewed coffee. Our objectives were to determine quality coffee obtained by different brewing methods as assessed untrained tasters characterize solid residues this extraction using medium infrared spectrum. Four evaluated 124 consumers. The infusion method presented better global impression preference these consumers than other methods. Significant...
Agronomic biomass yields of forage sorghum BRS 655 presented similar results to other energy crops, producing 9 12.6 tons/ha (dry mass) straw. The objective this study was evaluate the lignocellulosic part cultivar in terms its potential different unit processes production cellulosic ethanol, measuring effects pretreatment and enzymatic hydrolysis. Three types pre-treatments for two reaction times were conducted characteristics pulp subsequent saccharification. pretreated by alkali, acid...
The coffee growing in the state of Espírito Santo has some peculiarities that differ from other regions producing Arabica Brazil because it a diversity edaphoclimatic conditions influence final quality bean. This study aimed to demonstrate and quantify effect solar radiation different forms wet process on crops located altitude range 950 meters, order understand what would be best processing methods for cultivated East (sun-grown) South-Southeast (shade-grown). results indicate shading...
Mycelia of fungi produced edible mushrooms are functional or biofortified foods, due to their bioactive compounds and bioaccumulation microelements (e.g, Se, Fe, Zn). The use cheese whey for mycelial growth is an alternative take advantage this by-product the Dairy Industry produce a nutritional supplement with compounds. In study, production was performed after 25 days Pleurotus djamor in without selenium. P. capable growing producing biomass liquid culture medium containing This element...
The increasing on the levels of carotenoids in staple foods broad human consumption is one strategies food biofortification programs, mainly due to importance these compounds health prevention vitamin A deficiency. Maize a major its high regions where problems Vitamin deficiency are great relevance. programs have made progress determining amounts grain thousands accesses. This work aimed at studying influence color grains profile four different Brazilian genotypes. selection ears within same...
The multi-enzyme complex (crude extract) of white rot fungi Pleurotus ostreatus, eryngii, Trametes versicolor, Pycnosporus sanguineus and Phanerochaete chrysosporium were characterized, evaluated in the hydrolysis pretreated pulps sorghum straw compared efficiency with commercial enzyme. Most complexes had better rates purified
O objetivo deste trabalho foi caracterizar e avaliar a variabilidade quanto ao teor perfil de carotenoides nos grãos 134 genótipos milho (Zea mays), com vistas à utilização em programas biofortificação. Os materiais foram provenientes dos campos experimentais do Banco Ativo Germoplasma da Embrapa Milho Sorgo, Sete Lagoas, MG. São cultivares híbridos comerciais, linhagens-elite outros acessos escolhidos base na coloração amarelo-alaranjada endosperma. A quantificação totais, carotenos...
Abstract When it comes to the sensory analysis of specialty coffees, is necessary discuss protocol tests Specialty Coffee Association (SCA) and formation Q‐Graders as reliable parameters in analysis. However, training these use SCA has generated discussions scientific community demonstrated importance talking about level professional precision well protocol. This study sought understand relation accuracy efficiency coffees. Three experiments were carried out evaluate test hypotheses...
The purpose of this study was to investigate the adaptability and stability carotenoids in maize cultivars 2004/2005 growing season. Total (TC), total with provitamin A activity (Pro VA) (μg g -1 ) grain yield (kg ha were quantified 10 at five locations. chemical analyses conducted a laboratory EMBRAPA/CNPMS, Sete Lagoas, Minas Gerais. methodologies Eberhart Russell (1966), Lin Binns (1988) Rocha et al. (2005) used analyze stability. In general, linear regression model proposed by (1966)...
Maize is considered a source of carotenoids; however, these compounds are highly unstable, degraded by high temperatures, exposure to light and presence oxygen. The objective this work was evaluate the influence moisture type drying applied grains on level carotenoids in yellow maize. experiment conducted completely randomized design (2 × 4 factorial), two levels initial at harvest (22 19%) three types (in sun; shade dryer) control (no drying). samples after with 12% final were analyzed...
The objective of this study was to evaluate sensorially, by professional Q-Grader, the beverage coffee from fermentation natural and with use yeasts lactic acid bacteria as starter cultures in wet processing. Arabica harvested at two different altitudes Espírito Santo State. Both coffees went through 04 treatments: inoculated Saccharomyces cerevisiae (YML) or Pediococcus acidilactici CCT 1622 (LAF), (NF) (not inoculated) Control, without (WF). processed just process. After process roasting,...
O entendimento das necessidades dos clientes e a utilização de tecnologia alimentos podem tornar uma ideia em um produto inovador. objetivo deste trabalho foi estudar, por meio pesquisa mercado, oportunidade novo e, posteriormente, elaborar salada frutas frescas, utilizando técnicas processamento mínimo com métodos combinados. A mercado realizada na região metropolitana Belo Horizonte - MG para estudar o potencial avaliar aceitação pronta embalada. No processo desenvolvimento do produto,...
O Brasil destaca-se pela sua produção de cana-de-açúcar. açúcar mascavo é um nutritivo e saudável subproduto, obtido artesanalmente por agricultores familiares. Entretanto, como resultado artesanal, o apresenta diversidade na cor. objetivo deste estudo foi analisar a cor do aceitação no mercado Viçosa, Minas Gerais. Foram realizadas análises colorimétricas (CIELAB) os resultados avaliados mediante análise multivariada, medidas dissimilaridade similaridade, técnicas agrupamento (programa...
O objetivo deste trabalho foi avaliar o efeito da aplicação de herbicidas pós-emergentes no teor carotenoides em grãos milho verde. Utilizou-se delineamento inteiramente casualizado com cinco tratamentos - sem aplicação; foramsulfuron + iodosulfuron-methyl-sodium (40 g ha-1); nicosulfuron (20 mesotrione (120 ha-1) e tembotrione (100 duas repetições. Os foram avaliados para teores luteína, zeaxantina, betacriptoxantina, alfacaroteno betacaroteno, pró-vitamina A, totais percentuais zeaxantina...
