Uniformity analysis refers to the analysis of the uniformity of samples in the same batch. For example, at least three or more samples of trial production products are taken in different periods of time, and the indicators that are not easy to be mixed in the samples are tested and the coefficient of variation is analyzed.
Sampling methods and criteria for uniformity determination are provided, and sample uniformity is analyzed and explained. Sample uniformity analysis indicators include at least essential macro-nutrients, vitamins, minerals, optional ingredients and other ingredients that are not easily mixed. In each type of indicators, ingredients with small dosage and difficult to mix (such as active bacteria, lactoferrin) should be selected.
Uniformity verification of dry mix samples using base powder (or wet-produced semi-finished products) should, in principle, include the corresponding indicators of all dry mix components. For dry mixing with more nutrients, representative nutrients can be selected to verify the uniformity according to the actual situation and provide reasonable explanations.
