Group 1: Trans Fatty Acids in Tea Beverages - Trans fatty acids (TFA) are defined as unsaturated fatty acids with trans non-conjugated double bonds, originating from both natural and industrial sources [2]. - The natural source of trans fatty acids in dairy products is approximately 0.83g/100g, as reported by the National Food Safety Risk Assessment Expert Committee [3]. - The presence of trace amounts of trans fatty acids in products using real milk is attributed to natural sources, as indicated by the companies involved [3]. Group 2: Regulatory Standards - According to the National Food Safety Standard for Prepackaged Food Nutrition Labels (GB28050-2011), products can be labeled as "0 trans fatty acids" if they contain less than 0.3g/100g [4]. - Bawang Tea's product was found to have 0.0133g/100g of trans fatty acids, while Heytea's product had 0.113g/100g, both of which are below the regulatory threshold [4]. Group 3: Health Guidelines and Consumer Awareness - The Chinese Dietary Guidelines (2022) recommend that daily intake of trans fatty acids should not exceed 2 grams [5]. - Excessive intake of trans fatty acids is linked to increased risks of chronic diseases such as cardiovascular diseases and diabetes [5]. - The tea beverage industry is becoming more regulated, with Shanghai implementing a grading system for beverages based on their nutritional content, including trans fatty acids [7].
