Effect of high pressure homogenisation on the capacity of Lactobacillus plantarum A6 to ferment rice/soybean slurries to prepare high energy density complementary food Nguyen T. T.

Gelatinisation is a common pre-treatment which could be implemented to enhance the action of amylases, and has been successfully used in a former study (Nguyen, T. T. T., Loiseau, G., Icard-Verniere, C., Rochette, I., Treche, S., and Guyot, J.-P. (2007). Effect of fermentation by amylolytic lactic acid bacteria in process combinations on characteristics of rice/soybean slurries: a new method to prepare high energy density complementary foods for young children. Food Chemistry, 100, 623-631.) in combination with ALAB to prepare from a blend of rice/soybean flours semi-liquid fermented HED gruels with a high dry matter (DM) content (23-32%). In this study, it is shown that a mild pre-heating treatment which consists in suspending a rice/soybean flour blend in hot water (70 degrees C) combined with high pressure homogenisation (HPH) can substitute gelatinisation before fermentation by the ALAB Lactobacillus plantarum A6 to prepare HDE gruels after cooking of the fermented slurry. As an alternative, allowing better condition of handling and storage, spray drying can be applied to such pre-heated HPH treated fermented slurries to obtain fermented flours which can be used further to prepare HIDE gruels. specialized gruel rice soybean energy density high pressure homogenisation fermentation amylolytic bacteria spray drying 084 054 Food Chemistry 102 4 1288-1295 2007 0308-8146 https://www.documentation.ird.fr/hor/fdi:010037920 10.1016/j.foodchem.2006.07.020 0308-8146 [F B010037920] https://www.documentation.ird.fr/hor/fdi:010037920 https://www.documentation.ird.fr/intranet/publi/2007/05/010037920.pdf Accès réservé (Intranet de l'IRD) IRD - Base Horizon / Pleins textes 2007-06-01 2017-08-23 fdi:010037920 fre
