There are several methods for extracting citrus fruit juice. Two automated methods force the flesh and peel through a metal tube, releasing the juice through tiny holes. The peels of citrus fruits can be further processed by removing oils and reclaimed later on. Both automated and manual methods involve cutting the fruit in half and extracting the juice. Here are some of the benefits of automated methods for citrus juice extraction. Read on to find out what they are and how they work.
Fruit juice
A recent study evaluated the benefits of eating fruit and vegetables and found that consuming five to seven servings of fruit daily is associated with a 30 percent lower risk of dying young, compared to one portion per day. This is because fruits and vegetables contain health-promoting chemicals, and the consumption of fruit juice was linked to a decreased risk of coronary heart disease, stroke, and death. Similarly, the consumption of fruit juice was associated with lower rates of obesity and diabetes.
While the effects of drinking fruit juice on the human body are still not completely understood, research has suggested that it may be associated with reduced risk of obesity and cardiovascular disease. The United States Department of Agriculture recommends that children between two and eight years of age should consume a cup or more of fruit daily. Depending on their age, gender, and overall health status, children should consume half their daily recommended fruit intake from whole fruit. Although fruit juice consumption peaked during the early 2000s, overall fruit consumption has been increasing since then.
The objectives of fruit juice processing are to enhance shelf life, increase product safety, and maintain nutritional value and quality. Alternative processing technologies have been developed to reduce capital costs and improve the quality and safety of fruit juices. These techniques include reverse osmosis and forward osmosis. The latter process requires less energy and lower capital costs. The combination of different approaches to fruit juice processing is promising. Its low-cost, nonthermal methods allow higher concentrations without sacrificing product quality.
Cold-press juicers
There are many cold-press juicers to choose from, but how do you know which one is the right one for you? Here are some important factors to consider when buying a juicer. You should consider safety when making juice, and a good cold-press juicer will have extra-large centrifugal chutes to keep young children and pets away. A cold-press juicer should also be dishwasher-safe to help prevent messes.
Cold-press juicers use a two-step process to extract the juice. This results in smooth, silky juice. These machines are dishwasher-safe, and their stainless-steel parts are easy to clean. They also come with a 12-year warranty. Some models have a manual, so you can learn how to use them and find out what features they have. Cold-press juicers are ideal for anyone who wants to make their own fresh juices.
Cold-press juicers produce less noise than centrifugal juicers. They can process nuts, such as almonds and cashews, and can even make almond and cashew milk. Because cold-pressed juicers don’t produce high heat, they preserve more nutrients. A cold-press juicer also needs more prep time. While they may not be as efficient as a centrifugal juicer, they are still an excellent choice.
Shelf life of juice
Fruit juices have a short shelf life compared to other foods. The shelf life of raw juice is usually around seven days. HPP treatments can increase shelf life. However, it is important to keep in mind that cold-processed juices should be stored below 41 degrees F because Listeria may develop there. The FDA has set specific guidelines for fruit juice shelf life. In addition to the maximum shelf life, the FDA has set minimum and maximum periods for the shelf life of juices.
In a study of fresh pummelo juice, UV-C treatment was found to prolong shelf life by six weeks. However, the same juice preserved as much as a week after it was produced. In addition, the UV-C treatment reduced the amount of enzymes, resulting in a longer shelf life for the product. The process of UV-C treatment has several advantages and disadvantages, however. Some of these benefits may not be worth the tradeoff between flavor and shelf life.
Although citrus fruit can extend shelf life, it is not a perfect solution. The fruit juice you purchase should be stored in a refrigerator or cold-storage area. Excessive exposure to light and heat can damage its quality. If you keep your juice in a fridge, it can develop a cloudy appearance. If this happens, refrigerate the juice and consume it within three months. It will stay fresh for longer if properly stored.
