The ideal storage temperature for apple juice is between 0 ☌ (32 ☏) and 4 ☌ (39 ☏). Once the juice package is opened, or if it was not sealed and shipped without needing refrigeration by the manufacturer, it must be resealed tightly and refrigerated to avoid contamination from microorganisms such as bacteria. The appearance, texture, or taste of the juice might change over time. Sealed bottles of canned apple juice can be stored in a dark, cool place, such as a pantry or cupboard, to delay the degradation of the product. Storageįresh apple juice requires refrigeration. A 100 ml reference amount of unsweetened apple juice supplies 46 calories and no significant content of any micronutrients. Composition and nutritionĪpple juice is 88% water and 11% carbohydrates (including 9% sugars), with negligible content of protein or fat. Pathogens can be spread in a number of ways, such as contamination where the fruit is grown, being carried in contaminated containers, or due to poor handling and washing. coli 01, Salmonella, Cryptosporidium, Clostridium botulinum, and hepatitis A. The pathogens related to these food-borne illnesses included parasites, bacteria, and viruses. Unpasteurized juice and foodborne illnessesįrom 2000 to 2010, there were over 1700 cases in North America of illnesses related to drinking unpasteurized juice and ciders. Food and Drug Administration recommends the following thermal processing times and temperatures in order to achieve a five- log reduction of Cryptosporidium parvum as this parasite is more heat resistant than E. Pasteurizationīecause apple juice is acidic, typically with a pH of 3.4, it can be pasteurized for less time or at lower temperatures than many other juices. In cases where the apple juice is treated enzymatically, the typical class of enzymes used are pectinases. Apple juice is then filtered, with the number of solid particles remaining partly defining the difference between apple juice and apple cider. Depending on the company and end-product, the apples can be processed in different ways before pressing. The apples are then pressed and juiced right away to avoid spoilage. After the apples are picked, they are washed and transported to the processing facility. Approximately two medium McIntosh apples produce around 200 millilitres (7.0 imp fl oz 6.8 US fl oz) of juice. A common cultivar used for apple juice is the McIntosh. ProductionĪpples used for apple juice are usually harvested between September and mid-November in the Northern Hemisphere and between February and mid-April in the Southern Hemisphere. Apple juice is one of the most common fruit juices globally, with world production led by China, Poland, the United States, and Germany. In the United States, unfiltered fresh apple juice is made by smaller operations in areas of high apple production, in the form of unclarified apple cider. Russet apple juice from Bolney, Mid Sussex, England, in a glassĭue to the complex and costly equipment required to extract and clarify juice from apples in large volume, apple juice is normally produced commercially. The resulting expelled juice may be further treated by enzymatic and centrifugal clarification to remove the starch and pectin, which holds fine particulate in suspension, and then pasteurized for packaging in glass, metal, or aseptic processing system containers, or further treated by dehydration processes to a concentrate. Filtered and unfiltered apple juice Clarified apple juice, from which pectin and starch have been removed, in a plastic bottleĪpple juice is a fruit juice made by the maceration and pressing of an apple.
