Aceite De Ajo, or Garlic Oil, is fundamentally a lipid preparation derived from infusing garlic (Allium sativum) into a carrier oil, often olive oil, sunflower oil, or canola oil. From a nutritional standpoint, pure garlic oil is almost entirely composed of fats, yielding approximately 884 calories per 100 grams, consistent with the caloric density of lipids (9 kcal/g).
Its macronutrient profile is dominated by 100 grams of total fat, with zero carbohydrates and zero protein. The quality of the fat content is highly dependent on the base oil used. If the base is a common oil like olive oil, the fat composition will be rich in heart-healthy monounsaturated fatty acids (MUFAs), primarily oleic acid, which are known to support cardiovascular health by helping to maintain healthy cholesterol levels. If the base is a seed oil, the polyunsaturated fatty acid (PUFA) content, including Omega-6 fatty acids, will be higher.
Garlic oil typically contains minimal saturated fat (around 14 grams per 100g). A significant nutritional highlight comes from the garlic compounds themselves, particularly sulfur compounds like allicin, diallyl disulfide, and ajoene, which are lipid-soluble and infuse into the oil. Although these compounds contribute negligibly to the caloric or macro profile, they are the source of garlic's potent flavor and potential therapeutic benefits, including antioxidant and anti-inflammatory properties.
Crucially, however, the nutritional contribution of vitamins and minerals is generally minimal, as the oil preparation process, whether cold-pressed or heated, often leaves behind most water-soluble micronutrients that might be present in raw garlic (like Vitamin C or B vitamins). Trace amounts of Vitamin E and Vitamin K may be present if the base oil is rich in them. When consuming garlic oil, it is important to remember that it is a highly concentrated source of fat and calories, making portion control essential, especially in culinary applications where flavor density is paramount over volume.
