![]() High-intensity pulsed electric fields are being used as an alternative to heat pasteurization in fruit juices. ProcessingĪ variety of packaged juices in a supermarket Plants can make anywhere from 1 to 20 tonnes a day. Chemicals such as hydrogen peroxide can be used to sterilize containers. Packages that cannot stand heat require sterile conditions for filling. If the juice is poured into a container while hot, it is cooled as quickly as possible. Juices are then pasteurized and filled into containers, often while still hot. Juices can also be sold in a concentrated state, in which the consumer adds water to the concentrated juice as preparation. The juice is then later reconstituted, in which the concentrate is mixed with water and other factors to return any lost flavor from the concentrating process. About two thirds of the water in a juice is removed. Juices are concentrated by heating under a vacuum to remove water, and then cooling to around 13 degrees Celsius. The second method requires the fruits to be cut in half before being subjected to reamers, which extract the juice.Īfter the juice is filtered, it may be concentrated in evaporators, which reduce the size of juice by a factor of 5, making it easier to transport and increasing its expiration date. The peels can then be used further, and are washed to remove oils, which are reclaimed later for usage. The juice of the fruit, then escapes through small holes in the tube. In the first method, two metal cups with sharp metal tubes on the bottom cup come together, removing the peel and forcing the flesh of the fruit through the metal tube. Straining, filtration and clarificationĪfter the fruits are picked and washed, the juice is extracted by one of two automated methods.Common methods for preservation and processing of fruit juices include canning, pasteurization, concentrating, freezing, evaporation and spray drying.Īlthough processing methods vary between juices, the general processing method of juices includes: Additives are put in some juices, such as sugar and artificial flavours (in some fruit juice-based beverages) or savoury seasonings (e.g., in Clamato or Caesar tomato juice drinks). Many commercial juices are filtered to remove fiber or pulp, but high-pulp fresh orange juice is a popular beverage. Juice may be prepared in the home from fresh fruit and vegetables using a variety of hand or electric juicers. For example, orange juice is the liquid extract of the fruit of the orange tree, and tomato juice is the liquid that results from pressing the fruit of the tomato plant. Juice is prepared by mechanically squeezing or macerating (sometimes referred to as cold pressing ) fruit or vegetable flesh without the application of heat or solvents. Apply pad of paper towels and weight down with brick.Pomegranates getting washed prior to processing in an Afghanistan fruit concentrate factory. Light will cause peroxide to change back to water so no rinsing is necessary. Blot and repeat until carpet is stain free. ![]() If there is still some stain on the carpet and blotting is not removing it, then moisten the tufts in the stained area with 3% hydrogen peroxide.Spray lightly with water, do not blot this time apply pad of paper towels and brick and allow to dry.Rinse with tap water using a spray bottle, blot to remove excess moisture. ![]() If spot is being removed continue applying detergent and blotting with a white paper towel until spot is removed. (To make the detergent solution mix 1/4 teaspoon of a hand dishwashing detergent which does not contain lanolin or bleach with 1 quart of water) Use a blotting motion to work the detergent into the affected area.
