Abstract Milk is a key food worldwide prone to mycotoxins contamination. Lactobacillus plantarum and prebiotics detoxification ability was evaluated by a Plackett-Burman Design considering the reduction of aflatoxin B1 (AFB1) and its bioaccessibility in artificially contaminated ultra-high temperature cow milk. Six variables were evaluated: AFB1 concentration (from 5.0 to 10.0 μg L−1); incubation time (0 to 6 h); and inulin, oligofructose, β-glucan, and polydextrose concentrations (from 0.00 to 0.75%). The reduction in AFB1 ranged from 0% to 55.85% and in vitro bioaccessibility from 15.62% to 51.09%. The greatest reduction in AFB1 occurred by adding L. plantarum combined with inulin, oligofructose and β-glucan. The greatest reduction in bioaccessibility occurred by adding inulin or oligofructose and L. plantarum with a 10.0 μg L−1 AFB1 concentration. A sharp reduction in AFB1 was accompanied by higher bioaccessibility rates, and in this case, bioaccessibility is considered the main factor to ensure a low AFB1 absorption by the body. The best experimental condition was 10.0 µg L-1 AFB1, added of L. plantarum and inulin or oligofructose (0.75%), ensuring > 16% final bioaccessibility. Such results represent a safe AFB1 decontamination level for milk.

Neste trabalho, objetivou-se avaliar a qualidade de seis (6) diferentes fornecedores de envoltórios naturais suínos, utilizados para a elaboração de linguiça Toscana em um frigorífico localizado na região oeste do Paraná. As amostras foram codificadas como fornecedor 01, 02, 03, 04, 05 e 06, onde, com exceção do fornecedor 02, os demais foram de procedência nacional. As análises tecnológicas executadas nos envoltórios naturais foram a determinação da metragem, número de furos, número de fios por maço e a mensuração do calibre. Baseado nos resultados obtidos, o fornecedor 05 apresentou o pior desempenho. Não foi possível destacar um único fornecedor como o melhor para tal função. Sugere-se que a empresa em questão desenvolva formas de determinar o desvio padrão aceitável para os atributos, em especial, metragem, visando a melhor padronização do processo tecnológico.

The aim of this work was to evaluate the technological quality of six (6) different natural swine casings for the elaboration of Toscana Sausage at a sausage manufacturer locate in the west region of Paraná State. The samples were codified as supplier 01, 02, 03, 04, 05, and 06 and with exception of supplier 02, they all had Brazilian origin. The technological analyses in the natural casings were the determination of length, number of punctures, thread number per bundle and bore measurement. Based on the results obtained, the supplier 05 presented the worst performance. It was not possible to determine an ideal supplier for this purpose. It is suggested that the company develops ways of determining the best acceptable standard deviation of these attributes, in special, the length, aiming at the best technological standardization of the process for the industry.
