of phenolic compounds and aromatic nitrogen bases. The number of constituents in coal tar pitch is estimated to be in the thousands (HSDB 2000). A list of the components comprising the PAH fraction of coal tar pitch is shown in Table 4-7. Properties for this substance are similar or identical to those shown in Table 4-6 for coal tar creosote.

phenolic compound is present in this mixture, two extractions with base solution are not required; thus, the benzoic acid could be separated from the neutral compound by extraction with either aqueous sodium bicarbonate or aqueous sodium hydroxide solution. We have chosen to extract the acidic compound into the aqueous layer using sodium hydroxide.

Preservative Treatments for Fresh-Cut Fruits and Vegetables

although the phenolic content tended to decrease with delayed harvest time, phenolic levels did not always correlate with the susceptibility to browning (Amiot et al., 1995). In general, high concentrations of phenolic compounds are found in young fruits. While in bananas PPO activity is higher in the pulp than in the peel,
