There has been a body of research studying the effect of different factors on milk fermentation; the symbiotic relationship between M.O.s fermenting milk, milk composition, heat treatment, inhibitory substances (antibiotic residues, detergent residues, ...), packaging material and so on. But so far, I have not been able to find research studying the effect of container size/head-space on milk fermentation. Therefore, I kindly ask you to share with me any study concerning this factor.
Hello, really fermentation volume has some effect due to mass exchange rate so the major factor is starter amount used.
Karen A. Darbinyan Dear Karen, thank you for your response. But, considering the fixed concentration of the starter culture/mass of media, changing the headspace volume will affect the fermentation rate?
David Cau Thanks, Dear David. Yes, apparently there are other factors playing more important roles. However, using the same batch of the media, I employed two types of containers, and I had a different time of gelation (10 minutes differences in gelation point).
