Abstract The objective of this study was to prepare three donkey milk yoghurt formulations mixed with goat, cow and buffalo milk. The formulations were developed with 50% donkey milk and 50% cow, buffalo or goat milk. Concentrated mango pulp was added for flavouring. An evaluation was performed on the chemical composition of each milk sample and the formulated yoghurts. The donkey milk showed the lowest values for fat, protein, casein, total solids and non-fat solids. In turn, goat milk reached higher levels of fat and total solids. Furthermore, buffalo milk stood out with the highest values of protein and non-fat solids. Yoghurt made with donkey and buffalo milk showed higher concentrations of protein, lactose, total solids and non-fat solids. In contrast, the yoghurt that contained donkey and cow milk in its formulation obtained a higher fat percentage and a lower percentage of lactose, total solids and non-fat solids. The low content of fat and total solids in donkey milk, in addition to the structure of the casein micelles and small fat globules favor low consistency in fermented products. Thus, mixing donkey milk with milks from other animal species can result in better chemical composition and better consistency.

Abstract This study aimed to develop Greek style yoghurts with the addition of bovine colostrum. Four yoghurt formulations were produced with different colostrum content (0%, 10%, 20% and 30%). The fat, protein, total solids, ash, retinol levels were quantified as well as the colour was measured. A sensory analysis was conducted with 103 untrained panelists, evaluating the attributes of appearance, aroma, consistency, flavour, overall acceptance and the purchase intention. Colostrum addition increased the fat and protein levels in the yoghurt formulations. The Greek style yoghurts with bovine colostrum reached sensory acceptance above 70% for all attributes.

Abstract The objective of this work was to investigate the factors which affect the consumption of organic foods enriched with functional properties. The study was developed by investigating the consumer profile of organic and functional foods by applying a questionnaire hosted on the Google Forms® platform (docs.google.com/forms/). The obtained results show that individuals in the age group 31 to 40 years old and those 51 and older, widowed, divorced and inhabitants of the Midwest, Southeast and South regions consume organic food more often. The education level did not influence the willingness to pay more for the purchase of an organic food, the consumption frequency or the interest in consuming organic food with functional potential. The interviewee group had a monthly income of up to R$4,686.00 (In Reais - 5 minimum monthly salaries) and showed a consumption frequency between “almost never” and “sometimes”, while those with an income higher than R$4,686.00 presented between “sometimes” and “often”. Residents of capital cities and from smaller cities showed similar behavior for all variables analyzed. We can conclude that the degree of confidence and the interest in consuming organic foods with functional potential were little influenced by socio-demographic differences.

Abstract Our aim was to evaluate the sensorial acceptance and consumption intent of pasteurized milks and coalho cheeses produced with milk with low (80,000 cells/mL) and high (480,000 cells/mL) somatic cell count (SCC) level. Low SCC pasteurized milk (LCC) obtained statistically higher scores on the aroma, consistency, flavor and overall liking attributes in comparison with high SCC pasteurized milk. LCC mean scores for all attributes were statistically higher than high SCC Coalho Cheese. High SCC in raw milk has a detrimental effect on the quality of pasteurized milk and coalho cheeses as it presented lower sensory acceptance, failing to meet the consumer’s desired expectations.
