Vitamin A was determined by the Sb trichloride colorimetric method in different types of margarine samples, results which observe the legislation being obtained. In order to estimate the stability of vitamin A in margarine an experiment aimed at determining the concentration in margarine samples preserved in different ways for 90 days was initiated. The obtained results point out the maintainance of vitamin A at high values, between 63 per cent and 85 per cent of the initial content, as compared to the control, in which only 50 per cent of the added quantity was found.
采用三氯化锑比色法测定了不同类型人造黄油样品中的维生素A，结果符合相关法规要求。为了评估人造黄油中维生素A的稳定性，开展了一项实验，旨在测定以不同方式保存90天的人造黄油样品中的维生素A浓度。所得结果表明，与对照组相比，维生素A在人造黄油中的含量保持在较高水平，为初始含量的63%至85%，而对照组中仅发现添加量的50%。
