Apple Juice Case Study
There are several advantages of consuming juices especially the powdered ones, such benefits involve needing lesser space for storage, inexpensive cost of bulk packaging, …show more content…
In this case, filtration will be done since the desired juice should be clear. There are various filters available but when it comes to apples, continuous filters with back flush capability are preferred wherein the juice contact surface should be stainless steel or food grade plastic (Bates, Crandall & Morris, 2001).
At this point of the process, the juice is now solid free and clear. It will then be subjected to pasteurization, which is the most important method of preserving apple juice. Preservation of apple juice can be by refrigeration, pasteurization, concentration, chemical treatment, or irradiation (Root and Barrett, 2005). Heat pasteurization is the most important method of preserving apple juice which involves heating of the juice which is initially at 22˚C and is heated to 88 ˚C then cooled to 50 ˚C. This is done in order to destroy or kill organisms that could possibly develop.
In order to ensure that there are no solids or suspended particles left, a second filtration will be done, ultrafiltration. This involves filters with microscopic pores in order to remove the smallest particles left by the first …show more content…
In order to evaluate quality and adherence to fabrication parameters such as density, flavour, color, and natural fruit sugar content. It is also a must that the product is stored away from humid places since it is hygroscopic.
