Resumo: The objective of this study was to evaluate the quality of raw milk and the use of management tools in quality monitoring in industries in the northeastern Brazilian region. In the first study was to evaluate the seasonal influence on chemical composition, somatic cell count (SCC) and total bacterial count (TBC) in bulk tank milk. Data were obtained from milk samples from tanks collected monthly by industries registered with the federal inspection service (F.I.S.). The mean fat content varied from 3.51 to 3.69% and the protein content ranged from 3.07 to 3.17%. The averages of the somatic cell score ranged from 4.66 to 4.90 thousand cells/mL, and the transformed bacterial count ranged from 2.34 to 2.53 cfu/mL. The averages of the variables differed between two periods of validity of the Normative Instruction-62, and are presented in non-compliance with the limits established by the legislation. In the second study, was to evaluate the capacity index (Cpk) and the statistical process control charts as quality management tools for somatic cell counts (SCC) and total bacterial counts (TBC). The data were obtained from milk samples from tanks collected monthly by five industries with F.I.S in the state of Pernambuco. The Cpk index were calculated and control graphs were generated for Somatic Cell Score (SCS) and transformed bacterial count (tTBC). Only one industry presented a process acceptable or able to meet the established specifications for SCS and tTBC (1 ≤ Cpk ≤ 1,33). The control charts for the five industries indicated the presence of special causes (intermittent) in the process variation for the two variables. The results showed how industries need to improve processes for their milk suppliers to meet quality standards.

No primeiro estudo foi avaliada a influência sazonal sobre a composição química, a contagem de células somáticas (CCS) e a contagem bacteriana total (CBT) em leite cru refrigerado. Os dados foram obtidos de amostras de leite de tanques coletadas mensalmente por indústrias com cadastro no serviço de inspeção federal (S.I.F.). O teor de gordura médio variou de 3,51 a 3,69% e o teor de proteína variou de 3,07 a 3,17%. As médias do escore de células somáticas variaram de 4,66 a 4,90 mil céls./mL, e a contagem bacteriana transformada variou de 2,34 a 2,53 ufc/mL. As médias das variáveis diferiram entre dois períodos de vigência da Instrução Normativa-62, e apresentam-se em não conformidade aos limites estabelecidos pela legislação. No segundo estudo objetivou-se avaliar o índice de capabilidade (Cpk) e os gráficos de controle estatístico de processos como ferramentas de gestão da qualidade para os indicadores de contagem de células somáticas (CCS) e contagem bacteriana total (CBT). Os dados foram obtidos de amostras de leite de tanques coletadas mensalmente por cinco indústrias com S.I.F. Calcularam-se os índices Cpk e foram gerados gráficos de controle para escore de células somáticas (ECS) e contagem bacteriana transformada (tCBT). Apenas uma indústria apresentou um processo aceitável ou capaz de atender às especificações estabelecidas para ECS e tCBT (1 ≤ Cpk ≤ 1,33). Os gráficos de controle para as cinco indústrias indicaram a presença de causas especiais (intermitente) na variação dos processos para as duas variáveis. Os resultados demonstraram a necessidade de as indústrias aperfeiçoarem os processos, a fim de que seus fornecedores atendam os padrões de qualidade.Submitted by Mario BC (mario@bc.ufrpe.br) on 2019-07-02T13:45:29Z No. of bitstreams: 1 Viviane Maia de Araujo.pdf: 1386302 bytes, checksum: 0ff84b4307bd57da457d47a37f20b744 (MD5)Made available in DSpace on 2019-07-02T13:45:29Z (GMT).
