From "Hot-boiled Fruit Flavor" to "Original Orange Aroma": 600MPa Technology Redefines Orange Ju
2026-09-28 14:05:14
Many consumers have experienced this: many commercially available orange juices are overly sweet, lacking the refreshing peel aroma and fresh pulp of fresh oranges. This is often due to flavor loss caused by traditional heat sterilization processes. While high-temperature treatment can sterilize, it also causes a significant loss of heat-sensitive aromatic substances from the oranges, resulting in a product that tastes more like "orange-flavored sugar water" than the true flavor of fresh fruit. The widespread adoption of 600MPa ultra-high pressure sterilization equipment for oranges is fundamentally changing this industry landscape.
600MPa Pure Physical Pressure Locks in Over 90% of the Orange's Original Nutrients
Unlike traditional heat sterilization, which relies on high temperatures to inactivate microorganisms, the 600MPa ultra-high pressure sterilization equipment for oranges uses purified water as the pressure transmission medium. In a sealed container, it applies ultra-high hydrostatic pressure equivalent to a depth of 6000 meters in the deep sea to the pre-packaged orange material. The entire processing is controlled at a temperature below 10℃, with no heating throughout. Physical pressure is used to disrupt microbial cell membranes and inactivate polyphenol oxidase, achieving sterilization while preserving almost all vitamin C, flavonoids, limonene, and natural aromatic substances in the orange pulp. Extensive production verification data shows that orange products processed with this equipment retain over 90% of their vitamin C content, and the retention rate of citrus flavonoid activity is significantly higher than that of products sterilized by traditional heat.
Solving the Browning Problem: Enzymatic Browning for Brighter Orange Products and Longer Storage Life
Enzymatic browning has always been a pain point in orange processing. Traditional processes often require the addition of color-protecting ingredients to inhibit browning, which contradicts the current consumer demand for minimally sized ingredient lists. The 600MPa ultra-high pressure sterilization equipment for oranges effectively inactivates residual polyphenol oxidase activity while sterilizing, reducing browning in orange juice and pulp at its source and allowing the product to maintain a bright orange-yellow color for a longer period. Under standard cold chain conditions, the total bacterial count of processed orange products remains stable and controllable, extending shelf life to 30-90 days. This significantly expands the product's distribution radius and solves the industry-wide problems of perishable and difficult-to-transport freshly squeezed orange products.
Suitable for large-scale production, providing a new path for the upgrading of the citrus processing industry.
This equipment adopts an industrial horizontal structure design, with all food contact surfaces made of high-quality stainless steel. The pressure output is stable and precisely controllable, perfectly suited to the continuous production rhythm of juice factories. From laboratory-scale trials to large-scale production lines, the equipment can handle orange processing needs of different scales, helping companies produce high-quality orange products that meet domestic and international food safety standards without adding artificial preservatives. For many major citrus-producing areas in China, the 600MPa ultra-high pressure sterilization equipment for oranges not only increases the product premium of orange juice and orange pulp but also extends to more high-value-added deep-processed categories, driving the entire citrus processing industry towards "zero additives, high nutrition, and natural" upgrades.
