The addition of food waste caused gradual decreases of valerate and propionate, but ethanol increased and butyrate was relatively stable.

Percentage of metabolized acetate and propionate was lower than butyrate and valerate in both stomach compartments.

The addition of carbon-rich substrates significantly enhanced butyrate and ethanol accumulation, while protein-rich substrate substantially benefited propionate and valerate generation.
