The temperature of the juice is reduced to ca. 38°C and ca. 6% of the juice is vapourized. The juice is then re-heated before hot ftlling into cans or bottles. Direct heating by injected steam is efficient and compensates for water lost as vapour. It is sometimes considered, however, that off-taints are introduced by carry-over 38 Fruit juices from steam generation equipment and indirect heating may be preferred. In recent years the thermal load applied to single-strength citrus juice has been minimized by maintaining aseptic conditions after the initial heating.
In many plants, however, juice is recovered from pulp by back-wash leaching. This involves mixing the pulp with water and serial passage through finishers. These are operated at very low back- pressures to prevent further disintegration of the pulp and passage into the pulp wash. 3 Information leading to the arrest ... Adulteration of citrus juice became a major problem in the late 1970s, following a steep rise in prices in 1977. The Florida Orange Juice Commission, alarmed by the quantity of adulterated juice in the market place, established, during 1979, a fund of $500000 to support action against adulterators.

The headspace is flushed with steam to remove air and the sealed can is inverted to pasteurize the inner surface of the lid with hot juice. Cans are then cooled to ca. 20°C and stored at ambient temperature. Glass bottles are filled at 70-75°C. Care must be taken to minimize stresses during cooling and bottles pass fIrst through warm, and then cold water. Cooling is planned to lower the temperature to ca.
