辅食营养补充品货架期内营养素的稳定性及叠加风险研究

本文主要对5种辅食营养补充品(1种辅食营养素撒剂和4种辅食营养补充食品)在货架期内营养素的稳定性及叠加风险进行了分析。稳定性试验结果表明,对于辅食营养素撒剂,维生素B₁的平均衰减率最高,为34.62%,其次是维生素D (30.77%)、B₁₂(30.14%)、B₆(29.41%)和A (29.10%),相对稳定的是钙(5.22%)。对于4种辅食营养补充食品,相对稳定的营养素均为蛋白质(0~0.93%)和钙(2.17%~11.30%),相对不稳定的营养素有维生素A (25.77%~30.74%)、D (22.37%~33.82%)、B₁(17.81%~25.93%)、B₂(25.00%~28.00%)、B₆(26.03%~33.33%)和B₁₂(13.11%~21.54%)。不同的品种其营养素的平均衰减率有一定的差异性。营养素叠加风险研究结果表明,婴幼儿在食用婴幼儿配方奶粉的同时摄入辅食营养补充品,需要根据食用的婴配粉营养素含量,科学选取适合的辅食营养补充品,以免产生某些营养素摄入过量风险。对于未食用婴幼儿配方奶粉的目标人群,同时选择婴幼儿米粉及辅食营养补充品食用则无摄入过量风险,反而对目标人群是一个很好的营养补充。

Stability and Superposition Risk of Nutrients in Complementary Food Supplements during the Shelf-life

In this paper,the stability and superposition risk of 5 kinds of complementary food supplements(1 kind of sprinkles for complementary food supplement and 4 kinds of nutrient-dense food supplements for complementary feeding)were analyzed. Stability tests showed that for sprinkles for complementary food supplement,the average attenuation rate of vitamin B₁ was the highest(34.62%),followed by vitamin D(30.77%),B₁₂(30.14%),B₆(29.41%)and A(29.10%),and the relatively stable was calcium(5.22%). For the four nutrient-dense food supplements for complementary feeding,the relatively stable nutrients were protein(0~0.93%)and calcium(2.17%~11.30%). The relatively unstable nutrients were vitamin A(25.77%~30.74%),D(22.37%~33.82%),B₁(17.81%~25.93%),B₂(25.00%~28.00%),B₆(26.03%~33.33%)and B₁₂(13.11%~21.54%). The average attenuation rate of the nutrients in different varieties had a certain difference. The results of nutritional superposition risk showed that babies who consumed complementary food supplements while eating infant formula milk powder needed to scientifically select appropriate complementary food supplements to avoid the risk of excessive intake of some nutrients. However,for the babies who did not take in infant formula milk powder,the consumption of rice flour and complementary food supplements at the same time had no risk of overconsumption,but a good nutritional supplement.
