There are so many juice products available in groceries . Differentiating one from the other may be a hard task. Drinking it might be a healthy habit but it still depend on which kind you chose to take. Understanding each commodity is crucial in decision making.
1. Fruit Juice. A 100% pure extract with all the vitamins and minerals intact. It should be fermentable or can be converted to ethanol. Canned products cannot be called “fruit juices” because processing requires addition of sugar and some preservatives to maintain quality and extend shelf life.
2. Fruit Purée. Product obtained by sieving the edible part of whole or peeled fruit without removing the
juice. It can also be described as extract plus pulp. I love to drink purée because its a rich source of fibers.
3. Concentrated Fruit Purée. Made from fruit purée by removal of at least 50% of its water content. It can be reconstituted by addition water.
4. Juice Concentrate . Fruit juice in which at least 50% of water is removed by any physical means. High temperature of processing may cause loss of some nutrients and flavors.
5. Juice drink. This consist of 70% water and 30% percent juice. Most commercial products contain as little as 5% real extract. Extract maybe replaced with concentrate, puree or powder. Addition of sugar or sugar substitute and artificial flavors compensates for the lack of taste. Health claims and realistic fruit pictures printed on label can be misleading.
6. Powder. It is the most stable form. Done by complete removal of water by any physical means. Popular method are spray drying and drum drying. Essential nutrients are loss during the process. It maybe added back through fortification.
7. Fruit nectar. Product obtained by sweetening fruit extract with honey or sugar. Sweetening agent may not exceed 20% of the total weight. Nectar is generally accepted to denote a beverage that contains fruit juice or puree, water, and which may contain artificial sweeteners.
