Calamansi

Not typically, since calamansi is usually cooked down into sauces or squeezed for its juice. That said, citrus segments (if left in the surrounding membrane) and seeds in general are choking hazards for babies and children. To minimize the risk, remove the seeds and watch a child closely when serving a wedge of calamansi. As always, make sure you create a safe eating environment and stay within an arm’s reach of baby during meals. For more information on choking, visit our sections on gagging and choking and familiarize yourself with the list of common choking hazards.

No, calamansi is not classified as a common food allergen. However, self-reported sensitivity to citrus is described frequently in medical literature around the world. Also, individuals with Oral Allergy Syndrome (also called pollen-food allergy syndrome) may be sensitive to citrus fruits such as calamansi. In particular, individuals who are allergic to grass and certain tree pollens may also be more sensitive to citrus fruits. Oral Allergy Syndrome typically results in short-lived itching, tingling, or burning in the mouth and is unlikely to result in a dangerous reaction. Heat-treating calamansi juice, such as in cooking, can help to minimize or eliminate the reaction.

Note that calamansi is highly acidic, and exposure to the acid may cause a harmless rash on the skin, typically around the mouth. It usually dissipates after a short time. Additionally, the acid can be irritating on a baby's digestive tract, as well as cause or worsen diaper rashes when consumed in excess. The peel of calamansi also contains a compound called limonene, which is a known contact allergen, and can cause allergic contact dermatitis in sensitized individuals.

Calamansi is also associated with phytophotodermatitis, a skin condition that occurs when a person gets the juice from the fruit on the skin and doesn't wash it off. Compounds in the juice are activated by the sun and cause a pigmented, itchy, and occasionally blistering and painful rash on the skin. Cleansing the skin after citrus contact and using sun protection can help to prevent the phytophotodermatitis rash.

As you would when introducing any new food, start by offering a small quantity for the first few servings. If there is no adverse reaction, gradually increase the quantity over future meals.

Yes. Though calamansi is often consumed in small amounts, this tiny citrus is a healthy addition to baby’s meals. Calamansi contains vitamin C, which powers baby’s immune system and aids in the absorption of iron from plant-based foods. The peel contains several plant-based compounds that have antibacterial, anti-inflammatory, and antioxidant properties.

★Tip: Leftover calamansi juice can be frozen in containers or in ice cube trays, stored as frozen cubes in plastic freezer bags for up to 6 months, and defrosted and used in cooking later.

No. While calamansi is high in soluble fiber and pectin, it is not typically consumed in amounts that would have a significant impact on digestion. Remember that pooping patterns can vary significantly from baby to baby. If you have concerns about your baby’s pooping and digestive function, talk to your pediatric healthcare provider.

No. Juice of any kind should not be given to babies unless directed to do so by a healthcare provider. After the first birthday, small amounts of juice (less than 4 ounces a day, ideally unsweetened or diluted with water to reduce sweetness) may be safely offered. That said, we believe it is best to wait to serve juice until age two and even then, to limit the amount offered to minimize sugar in a child’s diet. Regular and especially excessive consumption of sweet beverages (including juice) may reduce the diversity of foods and nutrients consumed and increase the risk of dental cavities.
