The complexities and interaction of composition on the quality perception of vermouth is illustrated with wild-apricot-based vermouth (Figs. 8.5-8.7). It shows that sweetness, flavor, and astringency are preferred at a sugar content of 8%, whereas body, appearance, and aroma were preferred at 12% sugar (Fig. 8.5). Body, flavor, aroma, and total acidity were scored better at an alcohol content of 19% (Fig. 8.6). The spice concentration preferred for volatile acidity, total acidity, flavor, and bitterness was 5% (Fig. 8.7), whereas body, sweetness, appearance, and astringency were preferred at a 2.5% level (Joshi et al, 201 la,b). 

The extent of hydrolysis of protein hydrolysates is measured by the ratio of the amount of amino nitrogen to the total amount of nitrogen present in the raw material (AN/ TN ratio). Highly hydrolyzed materials have AN/TN ratios of 0.50 to 0.60. To obtain the desired level of hydrolysis in a protein, a combination of proteases is selected. Serine protease prepared from Bacillus lichenifor-mis has broad specificity and some preference for terminal hydrophobic amino acids. Peptides containing terminal hydrophobic amino acids cause bitterness. Usually a mixture of different proteases is employed. The hydrolysis reaction is terminated by adjust-... 

Food. Aloe extracts are used as a flavor ingredient primarily in alcoholic and nonalcoholic beverages and in candy to impart a bitter note. Based on the reported average maximum use levels of about 0.02% in alcoholic (186 ppm) and nonalcoholic (190 ppm) beverages and 0.05% in candy, the extracts used must be tinctures or greatly diluted extracts, as standard extracts (e.g., solid extract or fluid extract) would contain too much active anthraglycosides to be safely used. The most preferred commercial aloe exudates used in bitter spirits (Port Elzabeth and Mossel Bay aloes) show a balance of major aromatic constituents not found in many other aloe extracts. ... 

Derivation of the Brossel-Bitter formula. In a static magnetic field the 6 P level of mercury splits into three magnetic sub-states which are essentially equally spaced for fields less than 10 G. Thus the simple result presented above does not apply for the detection scheme used in the Brossel-Bitter experiment and equation (16.20) must therefore be modified. The magnetic dipole transition probabilities for a system with a multiplicity of equally spaced levels have been calculated quantum mechanically by Majorana (1932) and Rabi (1932). However, we prefer to return to our classical model in which the excited atoms are represented as electric dipole oscillators. When iT-polarized excitation is used, as in the Brossel-Bitter experiment, the axes of the dipoles at the instant of excitation are parallel to the z-direction. Under the combined influence of the static and rotating magnetic...
