The US Food and Drug Administration (FDA) has made significant changes to its standards for defining pasteurised orange juice, adjusting the minimum sugar content requirement that came into effect on 19 August. This alteration marks a notable shift in the parameters that delineate what constitutes orange juice under FDA guidelines.

Traditionally, the minimum soluble solids content in orange juice was set at 10.5° Brix, which indicates the sugar level within the juice. The new regulation now lowers this requirement to 10.0° Brix. Additionally, the updated guidelines permit an increase in the volume of Mandarin oranges and their hybrids included in orange juice from 10% to 15%.
The FDA’s decision to amend these standards is attributed to ongoing challenges faced by orange growers, particularly in Florida, where crops have been adversely affected by citrus greening disease and severe weather events. These factors have contributed to diminishing sugar levels in the fruit, prompting calls for a review of the existing Brix threshold.

The rule is a response to several petitions, notably from the Florida Citrus Processors Association and Florida Citrus Mutual, reflecting the concerns of local growers regarding declining sugar content and dwindling orange production. Collectively, these growers argue that the modifications will be essential for their long-term viability, particularly as they recover from the dual threats of disease and extreme weather patterns.
Despite some concerns raised during a public comment period, the FDA maintained that the new standards would not compromise the quality or nutritional value of orange juice. Critics had expressed unease that the lowered Brix requirement might lead to a decrease in sweetness and overall juice quality, potentially leading to consumer confusion regarding what qualifies as genuine orange juice. In its response, the FDA reassured the public that the sugar content would not be significantly affected, estimating a difference of just one gram of sugar per serving as a result of the change.
Health and Human Services Secretary Robert F. Kennedy Jr. has expressed support for the new regulations, which he considers a means to reduce reliance on foreign imports and modernise the industry. He stated that this adjustment would provide financial relief for domestic producers and encourage the use of American-grown oranges in juice products. This shift is particularly relevant given the dramatic drop in US orange production, which plummeted from 146.6 million boxes in the 2014-2015 season to an expected 58.3 million boxes for 2024-2025.
Furthermore, the FDA reports that imports of orange juice have seen a marked increase during this same period, rising from 280,000 metric tons in 2015-2016 to a projected 400,000 metric tons by 2024-2025. To comply with the stringent Brix standards, many manufacturers have resorted to blending American and imported orange juices, making the change in regulations a potentially profitable move for domestic growers.
Industry leaders have hailed the updated Brix standard as a practical solution for citrus farmers, allowing them to weather the challenges posed by both disease and climate impact. Daniel Hunt, president of Hunt Bros. Cooperative, a family-owned citrus company, remarked that the new rule offers essential support to growers who have made substantial investments in their agricultural practices.
Florida Citrus Mutual CEO Matt Joyner echoed this sentiment, commending the FDA for modernising the identity standard for orange juice. He emphasised that the changes have the potential to ensure that more domestically produced oranges can be incorporated into consumer juice products.
In a wider context, Kennedy noted that the FDA is also evaluating over 250 additional product standards aimed at modernising and deregulating various food and drink classifications across the board. This initiative reflects a broader trend towards regulatory flexibility intended to foster resilience and sustainability within the agricultural sector.
In summary, the FDA’s modification of the standards for orange juice appears to be a well-considered response to evolving agricultural realities. With an emphasis on supporting local growers, the new guidelines aim to strike a balance between maintaining consumer trust and safeguarding the livelihood of American citrus producers.
