Effect of mixing during fermentation in yogurt manufacturing.

Discipline: yogurt; Keywords: lactic acid bacteria, stirring, low-speed agitation, process time, acidity profile, microbiological dynamics.

Is agitation during fermentation beneficial to yogurt characteristics? This question was addressed by E.J. Aguirre-Ezkauriatza and coworkers in a study entitled: Effect of mixing during fermentation in yogurt manufacturing, which was published in the Journal of Dairy Science (2008), Volume 91, pages 4454-4465.
Effect of nitrogen flushing and storage temperature on flavour and shelf-life of whole milk powder

Discipline: milk powder; Keywords: oxidation, rancidity, off-flavours, light exposure, package atmosphere.

The objective of the study was to establish whether nitrogen flushing and colder than normal storage temperature will be favourable to flavour and shelf life of whole milk powder. This research by Dr M.A. Lloyd and colleagues was published in The Journal of Dairy Science, Volume 92 of 2009, pages 2409 to 2422. The title of the paper is: Effect of nitrogen flushing and storage temperature on flavour and shelf-life of whole milk powder.
