Milk, as one of the basic raw materials of animal origin, must be of adequate hygienic and physicochemical quality for processing. The aim of the article was to compare the quality of raw milk from three production systems, intensive, traditional (together referred to as conventional), and organic, as material for processing, as well as the quality of products made from it. Particular attention was focused on hygienic quality (somatic cell count and total bacterial count), physical characteristics (acidity), basic nutritional value (content of dry matter, total protein, casein, fat, and lactose), content of health-promoting substances (whey proteins, fatty acids, vitamins, and minerals), and technological parameters (rennet clotting time, heat stability, and protein-to-fat ratio). Research assessing the quality of organic milk and dairy products is significantly less extensive (if available at all) than for milk from conventional production (intensive and traditional). The available reports indicate that raw milk from organic farms is more valuable, especially in terms of the content of health-promoting compounds, including vitamins, fatty acids, whey proteins, and minerals. This applies to organic dairy products as well, mainly cheese and yoghurt. This is explained by the fact that organic farming requires that animals are kept in the pasture. However, the hygienic quality of the raw milk, and often the products as well, raises some concerns; for this reason, organic milk producers should be supported in this regard, e.g., through consultancy and training in Good Hygienic Practices. Importantly, milk production in the traditional and organic systems is in line with the concept of the European Green Deal.
牛奶作为动物源性基本原料之一,其卫生和理化质量必须达到适宜加工的标准。本文旨在比较三种生产体系(集约化、传统型(二者统称常规型)和有机型)的原料奶作为加工原料的质量,以及用其制成的产品质量。特别关注的方面包括卫生质量(体细胞计数和细菌总数)、物理特性(酸度)、基本营养价值(干物质、总蛋白、酪蛋白、脂肪和乳糖含量)、健康促进物质含量(乳清蛋白、脂肪酸、维生素和矿物质)以及工艺参数(凝乳酶凝固时间、热稳定性和蛋白脂肪比)。评估有机牛奶及乳制品质量的研究远比常规生产(集约化和传统型)牛奶的研究少得多(若有相关研究的话)。现有报告表明,有机农场的原料奶更具价值,尤其是在健康促进化合物含量方面,包括维生素、脂肪酸、乳清蛋白和矿物质。这一点也适用于有机乳制品,主要是奶酪和酸奶。这是因为有机养殖要求动物在牧场饲养。然而,原料奶以及通常产品的卫生质量引发了一些担忧;因此,在这方面应支持有机牛奶生产商,例如通过良好卫生规范方面的咨询和培训。重要的是,传统和有机生产体系中的牛奶生产符合欧洲绿色协议的理念。
