Jabuticaba is a fruit sensory appreciated and has significant nutritional functional value. However, it quite perishable, its use interesting for the preparation of other products such as fermented jabuticaba, from nutritional, biological technological point view. This study evaluated interference maceration time over antioxidant capacity, volatile compounds profile temporal dominant sensation jabuticaba. Four different treatments jabuticaba in fermentation times were prepared (96, 120, 144...

Faced with the search for healthy products that provide additional benefits to consumers' health, main objectives of this work were develop a low-calorie preserve containing prebiotics (lactulose and polydextrose) evaluate effects these on oxidative stress colon carcinogenesis in male rats treated 1,2-dimethylhydrazine (DMH). A total 62.5% w/w sucrose conventional preserves was replaced by polydextrose, lactulose added at 0%, 16%, 19.5% or 23% concentrations. The acceptance four guava...

Pasteurization and freezing are processes used in human milk banks that can affect some of the nutritional biological properties milk. The aim this study was to evaluate impact processing steps adopted by on contents total phenolic compounds antioxidant capacity vitro. Experimental realized, which 40 mL were collected from 8 mothers registered at Human Milk Bank Ouro Preto, state Minas Gerais. Samples homogenized form pool. divided into four portions characterized treatments: 1) immediately...
