The objective of this work was to evaluate the effect of processing two corn hybrids conserved, dry and humid grains, the dry matter (DM) and crude protein (CP) degradability in situ. The particle size was determined and difference was verified in MGD (Medium Geometric Diameter) of processed ingredients. Three sheep were used with rumen canulated, in a completely randomized design, using a factorial outline 2 x 2 x 3, being two corn hybrid, two conservation methods and three processing forms (whole, coarsely and finely ground), with five times of incubation (3, 6, 12, 24 and 48 hours). The fraction A in SDC (silage of dent corn) of DM was superior to GDC (grain of dent corn) in all of the particles size. The ensiling process increased the DM solubility, reducing the fraction B in comparison to dry grain. The values regarding the fractions DP and DE the 5% per hour of the protein, were larger for SDC and GDC, it presents a decreasing when the incubation time advances. The fermentation rate was superior for SDC and GDC. The ensiling process has positive effect in the decreasing of DM and CP in comparison to GDC.

Vinegar is a food product that has a great market potential and beneficial health properties. Each type of vinegar has its taste, since the transformation of alcoholic into acetic acid preserves the raw materials fragrancesand other organic acids can be formed. This study produced and characterized vinegars from ginger and cassava starch. The raw materials were first hydrolyzed by an enzymatic process, thenthey suffered an alcoholic fermentation,and finally an acetic fermentation by the Orleans process. The ash quantity, total acidity in acetic acid, dry extract, and alcohol content of the final product were analyzed based on the current vinegars legislation.The results showed that it is possible to obtain vinegars with good quality from ginger and cassava starch.
