Apple juice, in its pure, unadulterated form, is inherently free of gluten. Gluten is a protein found in wheat, barley, rye, and triticale. Standard apple juice production involves extracting liquid from apples; this process does not introduce gluten. An example of pure apple juice is that produced solely from pressed apples, without added ingredients containing gluten.
The absence of gluten in apple juice allows individuals with celiac disease or gluten sensitivity to safely consume it. This provides a readily available beverage option for those adhering to a gluten-free diet. Historically, the understanding of gluten intolerance has evolved, leading to a greater demand for gluten-free food and beverage choices, including the confirmation that pure apple juice fits within these dietary parameters.
