This work aims to study three methods to evaluate the olive ripening state based on the colour changes of ‘Cobrançosa’ and ‘Galega Vulgar’ fruits, in early ripening. The relation between colour change and fat content was also performed. The methods under study were: IM – ripening index (Jaén) (with 8 groups of colour); IMS – simplified ripening index with only 3 colour classes; CI – colour index, using the CIE ...
Modelling and optimization of the operation conditions of olive oil extraction were performed, using surface response methodology, following a central rotation composite matrix, as a function of the contents of enzymes (Endozym Olea AS; 0.04- 0.24%) and natural microtalc (FC8-AW; 0.12-0.68%) added at the beginning of the thermobeating step. Yield was evaluated by the extractability index and by the residual pom...
Com o objetivo de desenvolver um modelo de programação linear para simular os níveis das atividades do processo de produção, utilizou-se o sistema de produção da fazenda Lagoa do Fogão, propriedade da família Sakai, localizada no município de Guaíra,SP, com um total de 207 ha irrigados por três sistemas de irrigação do tipo pivô-central. A função objetivo consistiu em maximizar o lucro da propriedade agrícola, ...
