The pasteurizing conditions will inactivate enzymes and thus maintain physical stability and provide a high degree of microbiological protection from spoilage. Keep in mind that many powdered juice concentrates pack added sugar, so you’ll want to read labels carefully. Fig. If no additional ingredients, like sugar and preservatives, are added to a "from concentrate" juice, it's no worse than a juice that's not from concentrate. Alternatively, filling the container with hot juice pasteurizes the package and the product, thus delivering product pasteurization. The kinetic model revealed stronger temperature dependence of ascorbic acid loss in high pressure treated juice. Yike Chen, ... Zhongli Pan, in Integrated Processing Technologies for Food and Agricultural By-Products, 2019. The citrus fruit processing industry is a multiproduct sector that utilizes the entire fruit. Which one makes the best choice? Compressing and then freezing the orange juice allows more efficient packaging and transportation. If you buy juice concentrates solely for their nutrients, you’re better off eating whole fruit. These terms are recommended with guidelines written by the Food and Drug Administration (FDA). During the first 22 days storage, microbial, cloud, and ascorbic acid values for lightly pasteurized juice were not different from those of fully pasteurized juice. When it is desirable to extend the processing season, fruit can be crushed and frozen for later processing. The majority of processed citrus fruits are oranges, accounting for around 80% of the total processed citrus (Fig. If orange juice … Concentrate means the juice was boiled down to remove water. For vegetable juice concentrates, choose low-sodium options or concentrates with less than 140 mg of sodium (6% of the DV) per serving (16). Many juice concentrates are rich in vitamin C and antioxidants, which may promote skin health and slow the effects of skin aging. Many studies show that concentrated powders of mixed fruits and vegetables are associated with decreased markers of inflammation and increased antioxidant levels (3). To make juice concentrate, whole fruits are thoroughly washed, scrubbed, and crushed or blended to produce a pulp. 8.1). Typical flash pasteurization conditions for microbial stability are 85 °C for 15–30 s although a higher temperature, typically 95 °C, is usually regarded as necessary for complete enzyme inactivation. “Single-strength juice,” also known as 100% juice, is either NFC juice, as defined below, or juice reconstituted from a concentrate by dilution with water to the natural single-strength Brix. Although initial yeast counts of such juices are usually low, yeast growth could occur during storage and counts could reach up to 106 CFU/mL, and sometimes the yeast growth is accompanied by gas production (Lawrence et al., 1959). Our daily newsletter arrives just in time for lunch, offering up the day's biggest science news, our latest features, amazing Q&As and insightful interviews. It is not uncommon to remove in excess of 20% of the water. Ice serves as a filter aid and provides excellent clarification of the juice. Water can comprise as much as 90% of juice (1, 2). P.R. In contrast to other previously published reports (Pieper et al., 1992), sensory evaluation by means of difference tests done by Siegmund et al. If it will become a more premium juice it goes through a flash pasteurization, which means a shorter process at a lower temperature than the full pasteurization process, leaving a tastier product. Both the single strength and the concentrate fruit juices could be preserved by the freezing method. Fruit juices and their derivatives are by far the most important products made from the major varieties. Is one healthier than the other? The shelf life of frozen fruit juices was reported to be about 24 months at a storage temperature of − 18°C (Celli et al., 2016). PLUS a free mini-magazine for you to download and keep. It commands a steadily growing market share and competes successfully with FCJ and retail frozen concentrate for home use. Additional advantages result from ice in the product during pressing. Healthline Media does not provide medical advice, diagnosis, or treatment. Storage temperatures were 0 and15°C. Rakuten partners with thousands of stores to get you additional cash back on your purchases. It is usually judged of higher quality than juice from concentrate and is slightly more expensive. Does Pumpkin Pie Need to be Refrigerated. Properly handled frozen fruit can provide substantial quality benefits to the jelly processor. It follows that the production of not-from-concentrate (NFC) juices is also seasonal. The first commercial citrus juice was canned orange juice, produced in California in the early 20th century. The U.S. Department of Health and Human Services recommends that you get less than 10% of your daily calories from added sugars. Extrusion of pulpy material through the press cloths is greatly reduced. Figure 8.1. 4. The juice is then packaged or further concentrated to produce juice concentrate. This trade involves orange juice in various forms. Carrot juice from 100% vegetable concentrate is a rich source of provitamin A, offering a whopping 400% of the DV per 8-ounce (240-ml) serving (7, 8). 21 CFR 102.33(g) [1]. On the other hand, demand for this eminently popular product is practically steady around the year. Besides thermal pasteurization, pulsed electric field (PEF) technology was studied as an alternative pasteurization method by many researchers (Cserhalmi et al., 2006; Yeom et al., 2000). The stability of ascorbic acid and color intensity in pasteurized blood orange juice during 1 month of storage at 4–37°C was investigated. In addition, concentrates often pack more carbs and calories per serving than whole fruit (17). This is the freshest tasting juice you can find, without actually squeezing the fruit yourself. Orange, pineapple, and apple juice products — including concentrates — are increasingly popular, with orange juice accounting for over 41% of the global fruit juice market (1). NFC juices are products that are obtained by pressing fruit, separating from pulp and debris to the required level, and then pasteurizing and packaging into containers for consumer use. Fresh, “raw,” or “freshly squeezed” unpasteurized NFC is in small but increasing demand by the nature-oriented consumers. Unlike NFC, citrus juice concentrate has a minimum value of 11.2°Bx because the concentrate plants mix concentrates from early, mid, and late seasons together to give the concentrate and subsequently its reconstituted juice the flavor, texture, and taste that meet the preferences of the market that the company is targeting. Respective values of shelf life increase for juices in pouches were 24% and 57%. Citrus fruits are seasonal. The product is then pasteurized and packaged. However, the extremely short shelf-life of such products limits their market potential. There may be an intermediate stage where juices are pasteurized and packed into bulk containers under aseptic conditions. No browning occurred in canned juices stored at 10 and 20°C, apparently due to the reducing action of tin in acidic medium. This process likewise cuts packaging, storage, and transportation costs (1). Save 52% when you subscribe to BBC Science Focus Magazine.
