Q55. According to the requirements of this standard, the unit of vitamin E is milligram α-tocopherol equivalent (mgα-TE), while the unit in the "Chinese Food Composition List (2009 Edition)" is mg. What is the difference between these?

Answer: The Chinese expression of mgα-TE is milligram α-tocopherol equivalent, which is the scientific expression unit of vitamin E content. Vitamin E in food has many forms, such as α-tocopherol, β-tocopherol, γ-tocopherol, etc., and each has different biological activities. In order to calculate the biological activity of total vitamin E, it is often necessary to determine the different forms of vitamin E in food and perform appropriate conversion, and express it in a scientific way in a form that the human body can absorb and use, so mgα-TE is used internationally to express it.

Q56. Why does the standard Q&A (revised edition) regarding trans-fat acids not include natural trans-fat acids? How to distinguish natural and unnatural trans-fat acids during testing?

Answer: This standard stipulates that when hydrogenated and/or partially hydrogenated fats and oils are contained in food ingredients or used in the production process, the trans-fat (acid) content should be declared. The trans-fat acids here mainly refer to the trans-fat acids produced during the oil processing, excluding natural trans-fat acids. Because the main source of trans-fat acids is hydrogenated oil. Since the content of natural fatty acids is very small, it has little influence on the test results, so there is no need to distinguish.

Q57. One of the exemptions from mandatory labeling in Article 7 of this standard is "drinks and alcohol with ethanol content ≥ 0.5%". Does 0.5% refer to mass fraction or volume fraction?

Answer: refers to the volume fraction

Q58. The clause 27 of standard Q&A (revised edition) says ‘Carbohydrates refer to sugars (monosaccharides and disaccharides), oligosaccharides, polysaccharides...’ Oligosaccharides include disaccharides, why are disaccharides listed separately? , In addition to oligosaccharides?

Answer: According to GB/Z 21922-2008 "Basic Terminology of Food Nutrition", "sugar, all monosaccharides and disaccharides. Such as glucose, sucrose, etc.", "oligosaccharides refer to the degree of polymerization 3~9 carbohydrates", therefore, oligosaccharides do not contain disaccharides

Q59. Please clarify whether this standard, especially its labeling requirements on the percentage of nutrient reference value (NRV), is applicable to foods exclusively for infants and children under 4 years of age?
