(Instituto de Tecnologia do Paraná - Tecpar, 2009-11)Ochratoxin A (OTA) is one of the most abundant food-contaminating mycotoxins. Its occurrence in several agricultural commodities has been considered a worldwide problem. This toxin is mainly produced by Aspergillus species. ... -
(Instituto de Tecnologia do Paraná - Tecpar, 2000-01)The low caffeine content in leaves of C. dewevrei (~ 0.5 mg/g) is due to a low biosynthesis associated with a fast degradation. On the other hand, high biosynthesis and low degradation confer a higher content (~ 8 mg/g) ...
-
(Instituto de Tecnologia do Paraná - Tecpar, 2020)Commercial roasted and ground coffees are usually blends of Coffea arabica and Coffea canephora. Considering the differences in price and sensory characteristics between these two species, the identification of the presence ...
-
(Instituto de Tecnologia do Paraná - Tecpar, 2013-05)This study investigated the microbiology of a hybrid anaerobic reactor (HAR) in the removal of pollutant loads. This reactor had the same physical structure of an UASB reactor, however with minifilters inside containing ...
-
(Instituto de Tecnologia do Paraná - Tecpar, 2010-03)The aim of this study was to evaluate the coffee germplasm of the Paraná Agronomic Institute (IAPAR) for resistance to the coffee-berry-borer. Preliminary field evaluation was performed in August 2004 and the fruits of ...
-
(Instituto de Tecnologia do Paraná - Tecpar, 2007-03)An indirect competitive enzyme-linked immunosorbent assay (ic-ELISA) for ochratoxin A (OTA) detection in green, roasted and instant coffees was developed using anti-OTA monoclonal antibody. Immunological reagents prepared ...
-
(Instituto de Tecnologia do Paraná - Tecpar, 2013-11)Two analytical methods for the determination and confirmation of ochratoxin A (OTA) in green and roasted coffee samples were compared. Sample extraction and clean-up were based on liquid–liquid phase extraction and ...
-
(Instituto de Tecnologia do Paraná - Tecpar, 2000-07)Endosperm is the main reserve tissue in coffee seeds. Coffee (Coffea arabica L.) seeds were germinated for six weeks and qualitative and quantitative changes in amino acids and proteins were investigated. The total content ...
-
(Instituto de Tecnologia do Paraná - Tecpar, 2022-11-11)The aim of this study was to develop an adsorbent from coffee husk, residue from the coffee industry by different activation methods and to evaluate its application in the treatment of effluent containing synthetic Ponceau ...
-
(Instituto de Tecnologia do Paraná - Tecpar, 2003-03)Dietary protein and energy utilisation of diets containing fresh and ensiled coffee pulp were studied on 3.2 ± 0.2 g Nile tilapia for 28 days. Diets formulation and feeding were designed on the basis of daily dietary protein ...
-
(Instituto de Tecnologia do Paraná - Tecpar, 2024-01-12)The use of computational simulation techniques is an important tool for the coffee harvesting issues, particularly the finite element method. The method is widely used in the structural analysis of agricultural machinery, ...
-
(Instituto de Tecnologia do Paraná - Tecpar, 2002-12)Young coffee plants from cultivar Mundo Novo of Coffea arabica were grown without irrigation for 32 consecutive days, to evaluate the effect of leaf water potential on damage caused by low temperatures, under controlled ...
-
(Instituto de Tecnologia do Paraná - Tecpar, 2020)Endophytic fungi belonging to the genus Muscodor now transferred to Induratia are known producers of bioactive volatile organic compounds (VOCs) with many industrial applications. However, the members of this genus have ...
-
(Instituto de Tecnologia do Paraná - Tecpar, 2001-10)A method for the evaluation of arsenic and selenium in soluble coffee by inductively coupled plasma atomic emission spectrometry with continuous hydride generation to attend the Brazilian food legislation is described. ...
-
(Instituto de Tecnologia do Paraná - Tecpar, 2005-07)The genetic variability of 40 accessions of C. arabica was evaluated using a combination of the random amplified polymorphic DNA (RAPD) technique and restriction digestion of genomic DNA. The genetic variability and the ...
-
(Instituto de Tecnologia do Paraná - Tecpar, 2005-01)The genetic variability for frost resistance was evaluated in field conditions and cold chamber among Coffea accessions. Results showed that C. liberica var. dewevrei and C. racemosa, as well as hybrids obtained from these ...
-
(Instituto de Tecnologia do Paraná - Tecpar, 2004-08)The objective of this study was to analyze the effect of biosolid composts (BC) and carbonized rice hull (RH) on the production of Coffea arabica L. cv Catuaí Vermelho seedlings (IAC H 2077-2-5-99) grown in tubets. A totally ...
-
(Instituto de Tecnologia do Paraná - Tecpar, 2000-03)Frost damages in a field experiment of pruning types and systems for the cultivars of Coffea arabica Catuaí and Mundo Novo, were evaluated at Londrina (23 o 22’S, 52 o 10 ́W), State of Parana, southern Brazil, during the ...
-
(Instituto de Tecnologia do Paraná - Tecpar, 2013-09)The objective of this study was to evaluate the influence of integral and decaffeinated coffee brews (Coffea arabica L and C. canephora Pierre) on the metabolic parameters of rats fed with hyperlipidemic diet. Thirty male ...
-
Influence of Silver Nitrate on Somatic Embryogenesis Induction in Arabica Coffee (Coffea arabica L.)(Instituto de Tecnologia do Paraná - Tecpar, 2019)The influence of silver nitrate (AgNO3), benzyladenine (BAP), and indole-3-acetic acid (IAA) on low frequency somatic embryogenesis (LFSE) induction in Caturra and Catuaí arabica coffee was evaluated. For the Caturra ...
