Mothers attending infant welfare clinics were asked to measure milk powder from a standard packet with the scoop provided by the manufacturers. Wide variations were found in the weight of powder obtained, with the highest scoop weight (5.6 g) being double the lowest (2.8 g). It is suggested that the scoop method of measuring milk powder is so inaccurate that the manufacturers should present their product in small pre-measured packets.
参加婴儿保健诊所的母亲们被要求用制造商提供的勺子量取标准包装奶粉。结果发现所量取的奶粉重量差异很大,勺子量取的最高重量(5.6克)是最低重量(2.8克)的两倍。有人认为,用勺子量取奶粉的方法非常不准确,制造商应该采用预先量好的小包装来销售产品。
