Fruit juices apple

UF is used to clarify various fruit juices (apple, grape, pear, pineapple, cranberry, orange, lemon) which are recovered as the permeate [Blanch et al., AlChE Symp. Ser. 82, 59 (1986)]. UF has also been used to remove pigments and reducing browning in wine production [Kosikowski in Membrane Separations in Biotechnology, McGregor (ed.), Marcel Dekker, New York, 1986]. 

Acetic acid can be produced by the enzyme-catalyzed oxidation of ethyl alcohol. The brown acetic acid in vinegar is produced from fruit juices (apple or grape juice) and is known as natural acetic acid. 

Fruit Juice. Apple juice processors are using UF to increase juice recovery, improve clarity, reduce materials cost, and to cold sterilize for aseptic packaging. 

Some fruit juices also exhibit Newtonian flow, such as filtered apple juice up to 30° Brix, Concord grape juice up to 50° Brix, and filtered orange juice of 10 and 18° Brix (Saravacos, 1970). This behavior is found in the 20-70°C temperature range. Depectinated and clarified fruit juices (apple, peach, pear, etc.) also exhibit Newtonian behavior (Rao et ai, 1984 ...

Oral liquid concentrates are available for use in patients who can more easily swallow a liquid. These concentrates are light sensitive and dispensed in amber or opaque bottles to help protect the concentrate from light. They are administered mixed in liquids such as fruit juices, tomato juice, milk, or carbonated beverages. Semisolid foods, such as soups or puddingy, may also be used. Perphenazine (Trilafon) concentrate should not be mixed with beverages containing caffeine (coffee, cola), tea, or apple juice because of the risk of incompatibility. 

In this presentation, we will take examples of different fruit juice processes and will try to relate enzyme activities, the role they play and the transformation they occur in terms of finished products. These examples will concern apple juice, french cider, pineapple and wine.

Caffeic acid is generally the most abundant hydroxycinnamic acid in fruit and vegetables. The richest sources are coffee (drink), lettuce, carrots, blueberries, blackberries, cranberries, sweet potatoes (whole, cooked, and raw) and potatoes (Table 2.2). Prunes, peaches, orange juice, apples, tomatoes, grapes, and grape products (Bet6s-Saura and others 1996) also contain small quantities of caffeic acid. 

This assay has been used to determine the antioxidant activity of common vegetables, fruits including apples and strawberries (Eberhardt and others 2000 Chu and others 2002 Sun and others 2002 MacLean and others 2003 Meyers and others 2003), and fruit juices (Lichtenthaler and Marx 2005). No studies have yet reported the application of TOSC assay for the assessment of in vivo antioxidant status. 

Pectin is used in foods in two forms, high methoxyl pectin and low methoxyl pectin. High methoxyl pectin is the form normally found in fruit while low methoxyl pectin is a chemically modified pectin. Pectins are acidic polysaccharides that occur in the cell walls of fruit. The commercial source of pectin is either citrus peel or apple pomace. The citrus peel is the residue from the production of citrus juices while apple pomace is the residue of cider production. Thus pectin is a by-product of either cider or fruit juice production. 

Forsyth and coworkers63 found organotin compounds in fruit juices. Thus juices from apple and passion fruit contained low or undetectable levels of butyl-, phenyl- and octyltin compounds. Octyltins were present in juices sold in containers constructed of poly(vinyl chloride) but not in those made from poly(ethyleneterephthalate). Therefore, the likely source of the octyltin was the PVC container material63.

Fruit juice contains both catechins and flavonols. Apple juice is one of the richest juice sources of catechins (containing 6.3 mg (—)-epicatechin/100 ml and 0.8 mg (+)-catechin/ 100 ml) whereas cranberry juice contains the most flavonols, mainly in the form of quercetin and myricetin (17.5 mg/100 ml and 4.7 mg/100 ml, respectively). 

Fruit juices such as grapefruit, orange, and apple may reduce the bioavailability and exposure of fexofenadine. This is based on the results from three clinical studies using histamine-induced skin wheals and flares coupled with population pharmacokinetic analysis. Therefore, to maximize the effects of fexofenadine, it is recommended that ALLEGRA-D 24 HOUR should be taken with water... 

Fruit juices processing may seriously affect flavanol content. For example, the preparation of commercial apple juice decreased the flavanol content in a stepwise manner. In particular, crushing and pressing, storage of the concentrated juice at room temperature and decolorization by treatment with activated carbon destroy the flavanols almost entirely [46]. 

Urinary excretion of quercetin increased significantly with dose and time after the consumption of fruit juice (blackcurrant and apple juice in a 1 1 mixture) in humans [75]. Ranges from 0.29-0.47% of ingested quercetin were found in the urine. The presence of quercetin in urine shows that it was absorbed by the gut, but the urinary content does not necessarily reflect absolute absorptive efficiency because absorbed quercetin may be metabolized (conjugated), stored and excreted through other routes such as the biliary tract. However, since quercetin is present in a variety of fruit and vegetables, plasma concentrations or urinary excretion of quercetin may potentially be useful as biomarkers of habitual intake of these foods.
