Organic milk as medium for lactic acid bacteria growth: A review

2023

Sabunevica, Stefanija | Zagorska, Jelena

In recent years, the demand for organic fermented dairy products has been growing. Lactic acid bacteria (LAB) are of major interest in the food industry due to their ability to form the quality and functionality of fermented products. A significantly higher LAB cell count is presented in organic (ORG) fermented products such as yoghurt and kefir, than their conventional (CONV) counterparts. There is still a lack of information on the possible explanation and evidence of ORG milk as a better medium for LAB growth. The aim of the present review is to summarise the results of research articles on the milk compounds and their effect on LAB growth, and to identify differences between ORG and CONV milk that may provide a plausible explanation for their influence on LAB growth in ORG milk. The monographic method was used in this study. According to the previous research, significant differences were established in a content and range of carbohydrates, nitrogen sources, fats, macro elements and microelements, as well bioactive compounds in ORG and CONV milk. The composition of ORG milk may have potential benefits for the development of LAB due to the higher concentration of peptides and long-chain polyunsaturated fatty acids in it.
