Juices, selected

The diverse nature of these effects is illustrated by recounting the experience of clinical pharmacologists who studied the pharmacokinetics of felodipine, a dihydropyridine calcium channel antagonist (14). They designed a study to test the effects of ethanol on felodipine metabolism. To mask the flavor of ethanol from the subjects, they tested a variety of fruit juices, selecting double-strength grapefruit juice prepared from frozen concentrate as most effective. 

Obtain about 100 mL of a beverage of your choice such as coffee, tea, milk, or a fruit juice. Select something that you drink, so you have an idea of what it normally tastes like.

The eady juice industry was largely a salvage operation. The principal source of raw material was misshapen, poorly colored, or skin blemished fmit unsuitable for the fresh, canned, or frozen fmit market. In the 1990s, raw materials are selected for suitabiUty for juice production, except for apple juice production which still uses much cull fmit (4).

The primary advantage of CD complexation is to stabilize and protect sensitive host molecules, such as flavors, odors, or pharmaceuticals. CDs sharply reduce the volatility, chemical, thermal and photo reactivity of guest moleciiles. More recently, CDs have been used for separation of components in solution. For example, CDs can remove reactive components from fhiit juices to prevent oxidation or eUminate bitterness. Attachment of CDs to chromatographic supports provides chiral separation, selective component removal and modified chemical reactivity. A number of modified and pol3nnerized CD materials have gained acceptance as separation media (9).
