FDA cuts the minimum sugar content for orange juice to 10 degrees Brix, the first change since 1963
Ten degrees Brix. That is the new floor for pasteurized orange juice under a final rule the Food and Drug Administration filed for publication on Friday, down from the 10.5 degrees fixed when the standard was first established in 1963. The same rule lifts the maximum share of unfermented juice from Citrus reticulata, the mandarin group, and its hybrids from 10 percent to 15 percent by volume. The rule publishes on July 20 and takes effect 30 days after that.
Both changes were asked for by Florida. The Florida Citrus Processors Association and Florida Citrus Mutual filed a citizen petition on July 22, 2022 seeking the lower Brix minimum, arguing that agricultural conditions had cut the average soluble solids content of the state's oranges and that the standard limited manufacturing flexibility without benefiting consumers. A second petition, filed on November 15, 2023 by the Florida Department of Citrus, the processors association, Florida Citrus Mutual and the Juice Products Association, carried the request on the mandarin limit. FDA proposed the rule on August 6, 2025. Fewer than 50 comments came back, and the agency writes that most supported the lower minimum.
The reason FDA gives is the fruit itself. Citrus greening, the bacterial disease also known as Huanglongbing, weakens orange trees and causes fruit to develop with lower Brix, and the agency notes that hurricanes reduce sugar content as well. Its position is blunt about the outlook: until a treatment is found to prevent or cure the disease, FDA says it is unlikely that orange production will recover or that Brix levels will return to what was previously observed.
The economics are recorded as a saving rather than a cost. FDA estimates roughly $28.4m a year annualized at 7 percent over 10 years, and $28.8m at 3 percent, from letting processors substitute cheaper lower-Brix domestic oranges and avoid blending with higher-Brix juice or concentrate. It found no compliance costs at all, on the ground that the rule requires nobody to do anything differently, and it certified that there is no significant economic impact on a substantial number of small entities. Some comments opposed the change, arguing it would let manufacturers sell lower-quality juice. FDA disagreed, writing that lowering the minimum does not compromise quality and that the effect on sugar and nutrient content is minimal.
