Papaya is among the currently most important tropical fruits grown in Brazil and world. The fruit mainly consumed fresh although it offers many industrial products. processing of this fruit, as well its consumption, results large amounts waste, such peels seeds. consumption one causes significant loss food value; therefore, new aspects on use waste by-products, or production additives, even incorporation flour have aroused great interest because these are products high nutritional value,...
Abstract The objective of this study was to chemically and sensorially evaluate dryprocessed coffees with an initial quality 82 84 points on the SCA (Specialty Coffee Association) scale, packaged in impermeable permeable materials, stored at room temperature a refrigerated environment for 9 months. sensory chemical beans evaluated beginning storage, as well after six nine results show that specialty natural higher score experience attenuation sweetness, acidity, body, aftertaste over months...
Abstract The aim of the study was to determine sensory quality coffee cultivated in Mantiqueira region Brazil (Minas Gerais State) and identify its main descriptors. red yellow fruit varieties ( Coffea arabica L.) grown environments with different slopes, at altitudes ranging from 932 1,391 m, analyzed three crop seasons. dry processing method wet method, based on mechanical removal skin mucilage, were used. variables through correspondence analysis. There no sample discrimination between...
O presente estudo foi desenvolvido para investigar o potencial dos ácidos orgânicos e bioativos presentes no grão cru discriminar a qualidade sensorial do café proveniente de diferentes genótipos métodos processamento. Durante as safras 2010, 2011 2012, foram analisadas da bebida perfil bioativos, cafeína, trigonelina clorogênicos (3,4 5-CQA) amostras representativas Bourbon Amarelo Acaiá. As coletadas em lavouras comerciais com altitudes variando entre 932 1391 m, município Carmo Minas, MG,...
Resumo Devido ao processamento industrial do mamão, uma grande quantidade de subprodutos dessa fruta é gerada. Dentre esses subprodutos, estão as cascas e sementes, que têm valor nutricional, pois apresentam valores consideráveis fibras, proteínas antioxidantes. O objetivo, neste estudo, foi desenvolver um pão fôrma integral adicionado farinha mista, proveniente das sementes mamão da cultivar Havaí. Na elaboração integral, adicionada mista (casca semente) em diferentes concentrações (0%, 3%,...
Esforços são empregados para identificar plantas com teores de antioxidantes que conferem benefícios à saúde. A capacidade antioxidante do pêssego deve-se aos compostos fenólicos, vitamina C e carotenoides. O objetivo deste trabalho foi caracterizar quatro cultivares pessegueiro (Aurora, Biuti, Diamante Douradão) em relação antioxidante, determinando o teor dos relacionados a essa atividade. Os frutos foram separados dois grupos: sem armazenamento armazenados por cinco dias temperatura...
Este estudo teve como objetivo determinar a composição química e fitoquímica das farinhas da casca semente de lichias (Litchi chinensis Sonn), família Sapindaceae, cultivar 'Bengal'. A centesimal, o valor energético total, sólidos solúveis, pH, acidez os teores compostos fenólicos, antocianinas, flavonoides, minerais, açúcares, vitamina C triagem foram determinados. farinha lichia apresentou maiores C, lipídios, proteínas, cinzas fibras, enquanto se destacou pelos potássio, enxofre, cobre...
A goiabeira (Psidium guajava) é uma planta nativa brasileira, e seus frutos são ricos em compostos antioxidantes os quais podem causar a oxidação das lipoproteínas, reduzindo o estresse oxidativo. Objetivou-se com este trabalho determinar essas substâncias atividade antioxidante farinhas dos cultivares Pedro Sato, Paluma Século XXI. Foram selecionados 35 de cada cultivar, levando-se consideração grau maturação. Os foram lavados, picados, congelados nitrogênio líquido liofilizados....
In recent years, different methods of fermentation have emerged for coffee, with the intention adding complexity to its flavor. To be able clearly identify information from sensory analysis, tools capable detecting small differences are needed. One such tool is multiple factor analysis (MFA). Thus, objective this experiment was evaluate effects time and storage on quality attributes using MFA. The coffee (Coffea arabica L.) samples collected study were Serra da Mantiqueira region – Brazil....
<p>A challenge in the packaging and export of specialty coffees is to avoid green coffee bean storage transport conditions that negatively affect sensory quality roasted beans. This study evaluated beans eight types storaged a warehouse Poços de Caldas, MG, Brazil, for 18 months (Brazilian phase) subject sea subsequent at import company (export United States, where it remained stored 14 months. Physical, chemical, analyses were performed Brazilian phase phase. Green high-barrier...
Fermentation using starter cultures has been considered an alternative and economically viable technology for the production of specialty coffees. This type promotes several benefits, such as increased sensory quality, control over fermentation process, predictability final product added value. Coffee (Coffea arabica L.) samples this study were collected in Presidente Olegário - MG (2018/19 crop year) Cerrado region Minas Gerais. The effects natural inoculation yeast Torulaspora delbrueckii...
The pineapple is a fruit that has wide acceptance worldwide both in natural form, as industrialized. Your peel residue generated by food industries and from this can obtain protein extract which good source of bromelain. This study aimed to peel, evaluate its enzyme activity healing properties skin lesions rats. Seven animal groups were used: control, treated with 5% extract, 10% pure extract; commercial bromelain, bromelain animals subjected tissue incision for 21 days. Proteolytic specific...
The quality of coffee starts in the field, and goes through harvesting post-harvesting processes, continues to storage transportation. beans aims stock a product for certain period time. However, factors such as metabolism grain, water content, environmental conditions warehouse, type packaging, time influence maintenance these characteristics, may negatively affect sensory aspects beverage. use high-barrier packaging or refrigerated practices are alternatives that can ensure grain during...
Coffee fermentation has emerged as an innovative post-harvest process in recent years. The effectiveness of this is conferring sensory notes to the coffee that would please consumer and allow for positive differentiation coffees. This achieved by monitoring different parameters procedure fermentation. In regard, present study aimed conduct a natural fruit up 96 hours followed (sensory characteristics aroma, flavor, acidity, body overall score 0 100) chemical analyses (bioactive compounds,...
Os antinutrientes interferem na absorcao de nutrientes, acarretando danos a saude quando ingeridos em altas quantidades. Devido esse fato, o objetivo deste trabalho foi determinar farinha da casca e semente mamao os antinutrientes, inibidores tripsina, oxalatos, nitratos fitatos, com finalidade assegurar possivel uso das mesmas formulacoes alimenticias. Tambem foram analisados atividade antioxidante compostos relacionados essa atividade, como carotenoides, vitamina C fenolicos. teores...
