Juices clarified

Circular basin clarifiers are most commonly fed through a centrally located feed well. The overflow is led into a trough around the periphery of the basin. The bottom gendy slopes to the center and the setded solids are pushed down the slope by a number of motor-driven scraper blades that revolve slowly around a vertical center shaft. This design closely resembles a conventional thickener. Like thickeners, circular clarifiers can be stacked in multitray arrangements to save space. Some juice clarifiers are also arranged in this way. 

The desirable properties of distilling wines include wines a) made from white varieties by fermentation of separated juice clarified as much as practicable, b) fermented without addition of sulfur dioxide, c) fermented with strains of yeast which form comparatively low amounts of fusel alcohols at temperatures below 75°F, and d) distilled as soon as possible after fermentation. 

Juice Clarifying Enzyme. One of the earliest reports on a clarifying and clotting enzyme in orange juice was by Cruess (9). 

Sweet and dry white wines result from the alcoholic fermentation of pure grape juice, clarified by settling. In comparison to red wines, only very small amounts of phenolic compounds are dissolved, as contact with grape solids only occurs during maceration prior to fermentation. 

In Table 7.6 the general composition of pomegranate juices clarified and concentrated by an integrated membrane system UF/OD is summarized. The UF essentially enables the removal of suspended solids, which remained totally concentrated in the retentate stream producing a clarified juice with physico-chemical and nutritional properties similar to those of fresh juice. A 3.2-fold concentration of total soluble solids was achieved by using OD without any back diffusion of solute or burned off flavour due to the hydro-phobic nature of the membrane (Cassano et al., 2011).

A newer juice concentration process, requiring minimal heat treatment, has been appHed commercially in Japan to citms juice concentration. The pulp is separated from the juice by ultrafiltration and pasteurized. The clarified juice containing the volatile flavorings is concentrated at 10°C by reverse osmosis (qv) and the concentrate and pulp are recombined to produce a 42—51 °Brix citms juice concentrate. The flavor of this concentrate has been judged superior to that of commercially available concentrate, and close to that of fresh juice (11). 

Clarified lime juice, made by mixing juice with filter aid prior to passing through a filter press, is the one clarified citms juice that is a significant article of commerce. The pasteurized bottled juice is popular for drink mixes, punch bases, and fountain drinks (13). 

Use of ultrafiltration (UF) membranes is becoming increasingly popular for clarification of apple juice. AH particulate matter and cloud is removed, but enzymes pass through the membrane as part of the clarified juice. Thus pasteurization before UF treatment to inactivate enzymes prevents haze formation from enzymatic activity. Retention of flavor volatiles is lower than that using a rack-and-frame press, but higher than that using rotary vacuum precoat-filtration (21). 

High test molasses is not a residual material, but cane juice, sometimes partly clarified, concentrated by evaporation, with at least half its sucrose hydrolyzed to invert (glucose and fmctose) by heating at the low juice pH (5.5).

GA is used as an emulsifier in beverages such as citrus juices, beer, and cola drinks. GA ability to stabilize foams is used in the manufacture of beer and soft drinks. Besides, it can be used for clarifying wines. 

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].

A recent patent issued to Leo and Taylor66 describes a method for the preparation of a colorless solution of PM from alfalfa. The ground leaves are pressed out and the juice is clarified with aluminum hydroxide. The latter may be produced in the press juice by the addition of calcium carbonate, and aluminum chloride hexahydrate. The precipitate carries... 

In the initial stages of purification, sucrose is recovered in juice form by crushing cane stalks or by extraction of sliced sugarbeets (cossettes) with hot water. The resulting solutions are clarified with lime, then evaporated to thick syrups from which sugar is recovered by crystallization. The final syrup obtained after exhaustive crystallization of sucrose is known as molasses. Enhanced recovery of sucrose from beet molasses is accomplished by ion-exclusion chromatography, a process used in some sugar mills in the United States, Japan, Finland, and Austria.
