Abstract(s)
O leite é um produto de elevada qualidade nutricional, ocupando lugar de destaque na
dieta humana especialmente na infância. É constituindo principalmente por água,
possuindo ainda teor considerável de proteína e gordura, sendo que o valor destes
parâmetros varia considerando a espécie produtora. Este produto alimentar deve chegar
ao seu consumidor nas melhores condições de salubridade e segurança, garantido as
melhores condições de temperatura e de execução de procedimentos capazes de
assegurar tal resultado. Todo o processo produtivo deve ser monitorizado sendo que a
realização deste estágio incidiu sobre o processo de recolha e transporte do leite. Na
entidade acolhedora, Transportes Quintino Augusto Branco & Filhos Lda, sucederam-se
diversos procedimentos com o objetivo último de garantir a qualidade do produto no
momento de entrega à Industria. O tratamento de documentação relevante ou a emissão
de ordens de pagamento foram algumas das atividades realizadas. Numa vertente mais
prática foram levados a cabo procedimentos de controlo de parâmetros de qualidade,
nomeadamente a monitorização da temperatura em momentos chave e a estudo de
análises químicas realizadas após a recolha do leite. Para estas últimas foi conduzida
uma análise estatística dos resultados produzidos ao longo de nove meses para
parâmetros como gordura, proteína, extrato seco, células somáticas, contagem
microbiana e índice crioscópico. Os resultados indicam a influência do mês de recolha
nos valores obtidos para os critérios avaliados, onde a maioria destes sofria um
decréscimo nos meses frios. A contagem microbiana e de células somáticas são os
valores considerados pela Empresa. O primeiro apresenta-se positivo, não ocorrendo
penalizações ao contrário do que acontece no segundo onde a média é a penalização,
devendo ser tido em consideração a realização de eventuais procedimentos para
localização de eventuais falhas processuais.
Este período revelou-se uma etapa de intensa aprendizagem permitindo um maior
entendimento do funcionamento do setor de transporte do leite e da importância e
vantagens do controlo de parâmetros de qualidade ao longo de todo o processo
produtivo.
Milk is a product of high nutritional quality, filling a tangible place in the human diet particularly during childhood. It is constituted mainly by water, yet having a significant content of protein and fat, and the value of these parameters varies considering the producing species. This food product has to reach its consumers in the best salubrity and safety circumstances and should be guaranteed conditions of temperature and performance procedures capable of ensuring such an outcome. The entire production process must be monitored, wherein the realization of this internship focused on the process of milk collection and transportation. At the host institution, Transportes Quintino Augusto Branco & Filhos Lda, various procedures with the ultimate aim of ensuring product quality at the time of delivery to the industry were conducted. The treatment of relevant documentation or issuance of payment orders were some of the activities undertaken. On a more practical component were carried out procedures to control quality parameters’, including temperature monitoring at key moments and the study of chemical analyzes performed after collecting the milk. For the latter was conducted a statistical analysis of the results produced over nine months to parameters such as fat, protein, dry matter, somatic cells, microbial count and cryoscopic index. The results indicate the influence of the month of collection in the values obtained for the evaluated criteria, where most of these suffered a decrease in the cold months. The microbial and somatic cell count are values considered by the Company. The first presents itself positive, does not occur any penalizations unlike the second case where penalization is the average classification should be taken into account performing procedures for locating possible procedural flaws. This period proved to be a stage of intense learning enabling a greater understanding of the functioning of the milk transporting sector and the importance and advantages of the control of quality parameters throughout the entire production process.
