SUMMARY:

Bovine colostrum and bovine whey are co-products of the milk and dairy product chain, rich in bioactive nutrients and with the potential to be used in preparing functional foods. However, technological and regulatory barriers in Brazil prevent excess bovine colostrum from being used and commercialized for human consumption. Thus, the objectives of this study were to gather information on the biological effects of bovine colostrum supplementation on human respiratory health and potential contributions of its nutrients in preventing and treating SARS-CoV-2 infection (coronavirus disease 2019 - COVID-19); to investigate the acceptance of foods derived from bovine colostrum by the Brazilian population; and to conduct a study on the nutritional quality of formulations based on bovine colostrum and whey. Thus, an online questionnaire was applied to investigate the acceptance of foods derived from bovine colostrum by the population, in which 1308 residents, with over 18 years, in 19 Brazilian states participated. Next, five formulations of bovine colostrum with whey were developed and subjected to slow pasteurization, in which the fat, protein, total solids, and defatted dry extract contents, pH, acidity, density, Brix degree and fatty acid content were determined before and after pasteurization. An enterobacteriaceae (CFU/mL) analysis was performed on the samples to verify the heat treatment effectiveness. As a result of the literature review, it was found that the consumption of supplements based on bovine colostrum showed positive effects on the respiratory health of humans, and it was speculated that their bioactive nutrients could help in preventing and treating COVID-19. In the research on the interest in consumption and in the purchase of foods derived from colostrum, it was verified that the investigated population had good intentions to consume and purchase these products. The development of a product from the associating colostrum with whey enabled nutritionally enriching the serum and made the colostrum more fluid, a factor which facilitated its heat treatment. In addition, the formulations presented a good fatty acid profile, with thrombogenicity and atherogenicity index close to that of bovine milk. Finally, slow pasteurization (62ºC - 65ºC for 30 minutes) was efficient to eliminate enterobacteriaceae (CFU/mL) in the samples.
