Aji Amarillo
Aji amarillo is a yellow chili pepper native to Peru, commonly used fresh or as a paste in Andean cuisine. It is a nightshade vegetable with moderate levels of vitamin C and capsaicinoids, the compounds responsible for its heat and some digestive effects.
Also known as: peruvian yellow chili, aji pepper, Aji amarillo chili, Yellow Peruvian chili, Capsicum baccatum

Aji amarillo (Capsicum baccatum) is a yellow chili pepper indigenous to the Andes region of Peru and other South American countries. It has a fruity, slightly smoky flavor and ranges from mild to moderately hot (approximately 30,000–50,000 Scoville units). In culinary use, it appears fresh in ceviches and salsas, or processed into a vibrant yellow paste as a key ingredient in Peruvian dishes like causa limeña and ají de gallina. The paste is also sold commercially as a condiment and cooking ingredient.
Aji amarillo is nutrient-dense relative to its low calorie content, providing a notable amount of vitamin C (values vary by ripeness and preparation) along with smaller quantities of vitamin A, potassium, and manganese. Like all chili peppers, it contains capsaicin and related vanilloid compounds (capsaicinoids), which activate TRPV1 pain receptors in the mouth and gastrointestinal tract. For most people, moderate consumption does not cause digestive distress; however, capsaicinoids can increase gastric acid secretion and may trigger reflux or stomach discomfort in sensitive individuals.
Digestive Tolerance and Sensitivity
Capsaicinoids in aji amarillo stimulate gastric acid production and may accelerate gastric emptying in some individuals. People with gastroesophageal reflux disease (GERD), irritable bowel syndrome, or ulcers may experience symptom exacerbation. Because aji amarillo is a fresh vegetable, it is low in calories and contains insoluble fiber, which supports normal bowel function. Cooking the peppers does not substantially reduce capsaicinoid content. Portion sizes in traditional cuisines are typically modest (5–15 grams of paste per serving), and this level is well-tolerated by most people without sensitivity to capsaicin.
Allergenicity and Nightshade Considerations
Aji amarillo is a member of the Solanaceae (nightshade) family. Nightshade allergy is uncommon but documented; symptoms include oral itching, throat irritation, or gastrointestinal discomfort. People with a known nightshade sensitivity or allergy should avoid it. Like other members of the nightshade family, aji amarillo contains trace levels of steroidal glycoalkaloids, though the concentration in ripe peppers is negligible and not a toxicological concern at typical food consumption levels. Individuals with inflammatory bowel conditions may wish to discuss intake with a healthcare provider given capsaicin's effect on gastric secretions, though clinical evidence of harm at culinary doses is limited.
Frequently Asked Questions
Is aji amarillo safe for people with acid reflux?
Aji amarillo contains capsaicinoids that can increase gastric acid secretion. People with GERD or reflux sensitivity may experience symptoms after consumption. If you have a known reflux condition, consult your healthcare provider about whether and how much to consume. Those without reflux can typically tolerate usual culinary portions (5–15 grams of paste) without issue.
Can aji amarillo cause a nightshade allergy reaction?
Aji amarillo is a nightshade vegetable, so people with a documented nightshade allergy should not consume it. True nightshade allergy is rare, but symptoms can include oral itching and gastrointestinal discomfort. If you suspect a nightshade sensitivity, consult your healthcare provider before consumption.
What are the main nutrients in aji amarillo?
Aji amarillo is a source of vitamin C, vitamin A, and potassium. It is low in calories and provides insoluble fiber. It also contains capsaicinoids, the compounds responsible for its heat and some of its physiological effects on digestion. Exact nutrient values vary by ripeness and preparation method.
Does cooking aji amarillo reduce its heat or capsaicinoid content?
Cooking does not substantially reduce capsaicinoid content. The perceived heat may change due to flavor profile shifts during cooking, but the underlying capsaicinoid concentration remains largely intact. People sensitive to capsaicin should not rely on cooking as a mitigation strategy.
