Physicochemical properties of Butter cheese from Marajó manufactured with buffalo milk and cow milk.

This study aimed to evaluate the physicochemical characteristics, texture and color parameters of the artisanal Butter cheese from Marajó, manufactured with partial substitution of buffalo milk for cow milk. Four formulations were elaborated: B100 (100% buffalo milk); B80 (80% buffalo milk + 20% cow milk); B70 (70% buffalo milk + 30% cow milk) and B60 (60% buffalo milk + 40% cow milk). Three replicates were performed. The partial substitution of 20%, 30% and 40% of buffalo milk caused the reduction of fat in 16.2%, 21.6% and 25.4%, and protein in 5.2%, 5.7%, and 6%, respectively, with decrease of elasticity, cohesiveness, gumminess and chewiness, but had no influence on the hardness. Moisture had significant and strongly negative correlation with elasticity, cohesiveness, gumminess and chewiness. Fat and protein had significant and strongly positive correlations with elasticity, cohesiveness, gumminess and chewiness. Significant differences were found for color variables L*, a*, b* and ho. The increase in cow milk concentration increased the yellowgreenish tonality, with an emphasis in yellow tones

Efeito da adição de leite bovino ao leite de búfala nas diferentes características do queijo artesanal do Marajó, tipo creme.

O objetivo do estudo foi comparar os efeitos da substituição parcial do leite bubalino por leite de vaca, nas características físico-químicas, de textura, cor e nos parâmetros sensoriais do queijo artesanal do Marajó tipo Creme, tradicionalmente elaborado com leite de búfala. Quatro queijos foram elaborados com as seguintes formulações: C100 (100% leite de búfala); C80 (80% leite de búfala + 20% leite de vaca); C70 (70% leite de búfala + 30% leite de vaca) e C60 (60% leite de búfala + 40% leite de vaca). Três repetições foram realizadas. Os resultados analíticos da composição (umidade, proteína, gordura, minerais e acidez); dos parâmetros de textura (dureza, elasticidade, coesividade, mastigabilidade) e dos atributos de cor (L*, a*, b*, C*, ho) foram significativamente diferentes entre as formulações. Por outro lado, a presença do leite de vaca não ocasionou alterações nos atributos sensoriais. Com base nos resultados desse estudo, concluiu-se que a adição de até 40% de leite bovino na elaboração do queijo tipo Creme não afeta a sua aceitação pelo consumidor, permitindo um abastecimento do mercado em períodos de entressafra, quando a produção do leite bubalino diminui

Critical success factors during the implementation of ISO 22000:2018

Purpose: The purpose of the paper is to evaluate why companies still struggle with ISO 22000 implementation and maintenance, identifying which aspects are key for its success. Design/methodology/approach - A literature review was carried out based on Scientific articles and implementation guides collected from Google Scholar, ScienceDirect and ResearchGate. Findings - Nine aspects seem to have a broader impact on organizations maintenance of ISO 22000 and other FSMS. Furthermore, the empirical research reveals that having an efficient food safety management system is a prerequisite for companys competitiveness. Practical implications - The findings show that many of the critical success factors for a FSMS implementation are based on regular and adequate management of people inside the company. Originality/value - A novel model of segmenting critical success factors is presented, which has practical implications for ISO 22000 achievement.(undefined)info:eu-repo/semantics/publishedVersio

Diversidade nucleotídica de genes envolvidos na biossíntese de ácidos clorogênicos de cafeeiros.

Os ácidos clorogênicos (CGAs) são compostos químicos importantes de Coffea spp. para a qualidade da bebida, pois eles interferem na adstringência e podem alterar o aroma e sabor da bebida. Aproximadamente 310.000 ESTs de Coffea estão disponíveis e possibilitam o acesso à variabilidade nucleotídica da planta e o desenvolvimento de marcadores moleculares ligados à qualidade da bebida para as principais enzimas da via de biossíntese dos CGAs: PAL, C4H, 4CL, CQT e C3?H. Neste trabalho foram detectados polimorfismos dos tipos SNP, INDEL ou SSR dentro das sequências nucleotídidicas disponíveis no Projeto Genoma Café e no NCBI. As sequências de ESTs de CGAs foram clusterizadas pelo programa Codon Code Aligner, assim como a detecção de polimorfismos e validação dos mesmos (qualidade de cromatograma). Foram identificadas seis isoformas para PAL, uma para C4H, seis para 4CL, duas para CQT e duas para C3?H. Os contigs formados apresentaram um total de 248 polimorfismos (236 SNPs e 12 INDELs), sendo 201 na região codante (127 não sinônimos e 74 sinônimos). A frequência dos polimorfismos foi maior nas regiões UTRs (1pol/54pb), em relação à codante (1pol/81pb). A análise das sequências de C. arabica permitiu a identificação de 2 subgrupos diferentes de sequências, referentes aos seus genomas ancestrais (C. canephora e C. eugenioides). Foi observada a presença de 67,4% dos polimorfismos entre os grupos ancestrais e 32,6% dentro dos grupos em C. arabica. Esses resultados vêm permitindo definir genes tanto para estudos de expressão de homeólogos de CGAs como para o desenvolvimento de marcadores moleculares para o mapeamento genético

Assessment of the biofuel production potential from phytoremediation sunflower biomass

There are presently more than 3 million contaminated sites all over EU, according to the EEA (report 25186 EN). Heavy metal contamination is of particular concern, as metals are not degradable. Phytoremediation is gaining attention from the public and is an attractive low cost alternative for soil requalification, by establishing a vegetation cover which will stabilize the site, avoiding dispersion of contamination and simultaneously removing pollutants. Although the fate of harvested biomass is a common obstacle for its implementation, it may represent an opportunity for producing energy. This work presents a novel integrated strategy comprising the utilization of all plant parts for the generation of biodiesel. Combinations of sunflower and plant growth promoting microbiota were assessed growing in agricultural and metal contaminated soils. Harvested plant tissues were analysed and it was possible to observe that accumulation of Zn and Cd was made mainly in the roots, followed by the stems and the flowers, with the values registered for plants grown in contaminated soils being higher than the reported phytotoxic levels described in literature. Also, plants grown in the agricultural soil presented higher biomass rates. Sunflower seeds were then used for oil extraction and it was possible to observe efficiencies of up to 20 ml oil/m2, with only the oil from plants grown in industrial soil presenting levels of 1.8 mg Zn/l. Plant stems were used for bioethanol fermentation with yields of up to 280 and 162 ml/m2 for plants growing respectively in agricultural and industrial soils. Once again only plants grown in the industrial soil presented detectable levels of 1.1 mg Zn/l (and no Cd).info:eu-repo/semantics/publishedVersio
