In this work were determining the total phenolic content, total flavonoids and antioxidant capacity in formulations of red fruit juice supplemented with different concentrations of aqueous extract of Brazilian green propolis. And, also was investigate the formulation sensory acceptance by volunteers' consumers. The addition of propolis to red fruit juice increased the content of total phenolic compounds and flavonoids, enhanced the antioxidant activity of the final product as assessed by radical scavenging DPPH and ABTS and FRAP methods, and no negative effect on consumer taste. All red fruit juice formulations containing propolis presented significant results through overall acceptability test and were approved in relation to purchase intent by the volunteer consumers. Formulation F3 (6.1 mg.mL -1 ) showed the best results. The antioxidant activity increment was proportional to the concentration of aqueous green propolis extracts added to the juice. The positive purchase intention reached up 64.75% of participants' acceptance. A new, sugar-free drink with pleasurable sensory and functional properties, combined with health benefits, has been obtained.

Colostrum human milk samples obtained from human milk banks received different treatments and were evaluated for their proximal composition, fatty acids composition and lipid quality. The total lipids content was maintained in the treatments. There was no difference in moisture, ash, total proteins, carbohydrates and energetic value for raw colostrum human milk and pasteurized colostrum human milk, and there was difference in ash, total proteins and energetic value for freeze-dried colostrum human milk and pasteurized + freeze-dried colostrum human milk. The fatty acids composition demonstrated no difference in the processes for 14 of 31 fatty acids identified. Furthermore, lipid quality indices were obtained, which were unpublished for colostrum human milk submitted to pasteurization and freeze drying. Principal component analysis showed similar behaviors for freeze-dried colostrum human milk and pasteurized and freeze-dried colostrum human milk. So, the processes used may be promising for application in colostrum human milk, due to the maintenance of its proximal characteristics and fatty acid composition.
