hydrocolloids may enhance white sauces in ready meals

replacing modified starch with hydrocolloids like xanthan gum can enhance the textural and stability of white sauces used in ready meals, says a new study from belgium. three hydrocolloids - guar gum, xanthan gum and carboxymethylcellulose – were used to formulate white sauces for ready-to-eat meals, with all three ingredients producing sauces that were indistinguishable from a sauce made with modified starch. the ingredients, and in particular xanthan, could therefore offer sauce manufacturers an option to overcome the limitations of modified starches, including texture loss and water exudation. researchers from ghent university published their findings in the journal of food engineering. “all hydrocolloids significantly reduced the amount of water exudate. hereby especially xanthan proved to be very effective,” wrote the researchers. “sensory evaluations revealed that for the concentration investigated, only the presence of xanthan could be detected by the consumers as an increased firmness. “furthermore there were no differences in taste and general preference between the sauces,” they added. formulation details the ghent-based scientists prepared a range of white (béchamel) sauces: guar gum (cargill), xanthan gum (cargill) and carboxymethylcellulose (cmc, cp kelco) used at either 0.1 or 0.25 per cent, or with modified starch (tate & lyle). the hydrocolloids produced thicker sauces, but this decreased following 30 days of refrigeration. the sauces also underwent sensory testing by a panel of 30 volunteers, with the 0.1 per cent sauces evaluated. according to the results, the sauce formulated with xanthan gum was perceived as firmer than the others, while no other firmness differences were noted.
