As a citrus fruit, the orange is acidic, with pH levels ranging from 2.9 to 4.0. Sensory qualities vary according to genetic background, environmental conditions during development, ripeness at harvest, postharvest conditions, and storage duration.
Identifying pH Levels. To identify an orange as either acidic, consider its pH. The pH scale is a tool that measures the acidity and alkalinity of an item. Items with a pH between 0 and 7 are acidic, while those with a pH between 7 and 14 are alkaline. Products that have a pH of 7.0 are neutral -- neither acidic or basic.
