tasteless odours can ‘trick’ senses in reduced salt foods
|
|
|
a new study has added to previous evidence that certain odours can give consumers a positive taste impression of reduced sodium foods by drawing on consumers’ memory of foods perceived as being salty. the food industry is currently working to a mandate of reducing sodium chloride levels in packaged and prepared foods, as part of an effort to curb excessive consumption linked to increase risk of high blood pressure and stroke. the world health organization recommends adults consume no more than 5g of salt a day. this has led to intense r&d on salt replacers and taste enhancers on the part of food ingredients companies, as reducing salt levels can have a negative impact on the sensory properties of products. a previous study has shown that lightly salted and aromatised water can evoke salty impressions; aromas of sardine or bacon gave a higher impression of saltiness than comté cheese or soy sauce. the new study, conducted by european sensory network scientists at inra in dijon, france, and partners in the netherlands, went a step further, using the aromas in complex foods. they developed a test product with variations of a simple, neutral-flavour mozzarella-like soft cheese with different grades of fat-content and dry matter levels. they tested the product on a group of 27 french consumers aged 19-61 with no previous experience in sensory analysis, who were asked to grade 16 different cheese samples under two separate conditions using a rating scale of 0-10. wearing nose clips, they rated the intensity of the four basic taste qualities of sour, salty, bitter, and sweet, and texture (firmness, moistness, and granularity). they also noted their preferences. in the second stage of the experiment the same procedure was carried out, but without the participants wearing nose clips. the researchers observed that the products produced differentiated texture perceptions when the nose clips were not worn. aroma had no impact on the perception of texture but a marked difference was observed in the taste of the models. in the clip-free tests, the cheese samples with sardine and comté-flavoured products were perceived as saltier than the unflavoured and carrot-flavoured products . the authors say the effect – called odour-induced saltiness enhancement (oise) – is particularly marked in high fat models. study leader génica lawrence explained: “odour-taste interaction and integration occur at the neural level. this interaction depends on the association between both stimuli. the perceived taste impressions of a food are the results of a variety of sensory signals that are perceived simultaneously and melded in the brain into a general impression. these impressions will be closely linked together in the memory.” “our study suggests that the measured addition of such aromas could be an effective new strategy for food manufacturers in counterbalancing the sensory shortcomings of salt-reduced foods.” she added that it would be worth investigating whether other aromas associated with sweetness, such as vanilla, could help in the formulation of lower sugar food products in the same way. source international dairy journal doi:10.1016/j.idairyj.2010.09.005 using cross-modal interactions to counterbalance salt reduction in solid foods authors: lawrence g, salles c, palicki o, septier c, busch j, danguin tt

bacon producers have warned that a last-minute change to the food information regulation (fir) could prove expensive for both manufacturers and consumers. new eu rules dictate that bacon that contains more than 5% water can no longer be sold as ‘bacon’, but must be described as ‘bacon with added water\'. but the british retail consortium (brc) has warned that very little uk bacon (within a £2bn market) contains less than 5% water, which it said performed important technical functions.

the uk food industry has given the european parliament\'s (ep\'s) final agreement on food labelling a mixed reception, with one consultant reckoning label changes cost £7,000 per product. passed by 606 votes to 46, the new food information regulation (fir) is expected to be published in the eu official journal in october. food firms will have three years thereafter to adopt the new rules.

how to win in the us food and drinks sector, the moves to cut salt in food and the work some multinationals are doing on sustainability are some of the issues discussed in the latest batch of reports from the just-food research store. food and beverage consumer trends in the us: winning strategies in a new decadethe recession has made consumers focus on value. industry players need to recognise how this and other factors like an aging population and the rise in non-nuclear family households will influence shopping behaviour.

for many consumers, though, eating gluten-free foods is a necessity, not a choice. they are gluten-intolerant due to a medical or health condition such as celiac disease, gluten/wheat intolerance or sensitivity, adhd, autism and other conditions. and while many people know they have these conditions, there are also those who are undiagnosed. both segments are benefiting from the improved awareness of gluten-intolerance and the growing number of products serving this sector.

seaweed may hold the key to reducing salt in foods without affecting the shelf life and taste of the product, according to a new project from the uk. researchers at sheffield hallam university, working in collaboration with seagreens, are exploring the potential of seaweed granules to replace salt (sodium chloride) in processed food. “this will change the food industry, undoubtedly,” dr andrew fairclough told foodnavigator.
