Prices for capsule and stick olive oil products, which more consumers are seeking for dieting, were found to vary widely by product.
The Korea Consumer Agency (KCA) on the 9th released results of tests and evaluations of quality and safety for 14 capsule and stick olive oil products sold on the market, as the so-called "ole shot diet," which involves drinking a mix of olive oil and lemon juice on an empty stomach, spreads.
The survey found that the price per serving was 263–1,093 won for capsule products and 348–2,133 won for stick products. Overall, capsule products were cheaper than sticks.
However, the picture changed when converted per 1 g (1 ml) of olive oil. Capsule products were 263–683 won, while stick products were 29–178 won, indicating sticks had a lower price per volume.
In terms of safety and quality, all products met the standards. No issues were found with oil freshness or safety such as heavy metals, and the contents of unsaturated and saturated fats were confirmed to meet the Codex Alimentarius standards.
However, there was a discrepancy in acidity labeling compared with actual test results. Among the 14 products of those surveyed, 12 provided acidity information on online malls, but the tested actual acidity was 128–311% higher than the labeled figures.
The agency analyzed that the discrepancy arose because labeled acidity values are presented based on imported raw materials, while olive oil naturally sees acidity rise the longer it is stored. Accordingly, the agency recommended that companies clearly indicate that olive oil acidity information is based on raw materials.
The Korea Consumer Agency (KCA) said, "Olive oil contains active components such as unsaturated fatty acids and polyphenols, but it is a high-energy food and intake should be controlled," and cautioned, "Excessive consumption can cause abdominal pain and nausea, so care is needed."
