Grape Musts

Easily assimilated nitrogen, vitamins, fatty acids, and some minerals are some of the yeast nutrients that foster vinification processes. Additionally, some climatic, biological or cultural factors may induce variations in grape-must nutrient contents. The lack of easily assimilated nitrogen by Saccharomyces cereivisiae yeast has been proven to be the main cause of poor or inadequate alcoholic fermentation. On the other hand, the use of bee pollen during the alcoholic fermentation of white grape-musts has shown a positive effect on both the fermentation kinetics and the quality of final wines. Thus, it has been proposed as a nutrient-activator for the vinification of Tintilla de Rota grape-musts. In this study, the kinetics of the alcoholic and malolactic fermentation of grapes-musts/wines, yeast populations, and assimilable nitrogen consumption and physicochemical properties of the wines were monitored. The results showed an improvement in fermentation kinetics when bee pollen was present, in comparison to the control samples. Bee pollen is associated with an increment in easily assimilated nitrogen grape-must content. It was also been noticed that lower pollen doses (0.1 and 0.25 g/L) did not alter the physicochemical and color parameters of the grape-musts and the final wines. All of these facts suggest that bee pollen could be used as a beneficial activator-nutrient for some of the processes involved in the production of red wines.

Recently, the automatic in vitro gas production techniques (e.g. Cone. 1994; Theodorou et al., 1994) have been developed to study rumen fermentation kinetics. Many approaches have been taken. This work investigates the suitability of different methods for estimating the rumen fermentation of two starch rich feedstuffs.

Two adult male sheeps fitted with rumen cannula were used in two experiments to study the effects of synchronization of carbohydrate and nitrogen supply in sugarcane bagasse based total mixed ration (TMR) on in situ nutrient degradation. The first experiment was aimed to create three TMR with different synchronization index. Ingredient feedstuffs of TMR were evaluated for its in situ organic matter (OM) and nitrogen (N) degradation kinetics. On the basis of the OM and N degradation kinetics of feedstuffs, three sugarcane bagasse based TMR were formulated with synchronization indexes of 0.37; 0.50; and 0.63; respectively. The TMR had similar levels of crude protein (CP), total digestible nutrients, and neutral detergent fiber (NDF). In the second experiment, the three TMR with different synchronization index were evaluated for in situ degradability characteristics of OM, CP, NDF, and sulfur. The in situ degradation of OM in TMR were decreased (P<0.05) with the increasing of synchronization index. The higher synchronization index in TMR increased (P<0.05) CP degradation of CP. The NDF degradation decreased slightly by the alteration of synchronization index in TMR. The higher synchronization index in TMR reduced (P<0.05) in situ sulfur degradation, and this may not support to effects of synchronization of carbohydrate and nitrogen supply.
