study gives noael level for soy
|

the no observed adverse effect level (noael) for soy in europe should be two milligrams, says a new study from switzerland, denmark and italy. the study, published in this month's issue of the journal of allergy and clinical immunology , offers industry and regulators an insight into the extent of soy allergy in europe, and might impact food-labelling directives. "we performed, for the first time, a clinical multi-centre study on food allergy to soy in europe, including double-blind, placebo-controlled food challenges and determination of threshold levels for clinical reactivity to soy," wrote lead author barbara ballmer-weber from university hospital, zurich escalating incidences of food allergies in europe and the desire to avoid potentially harmful consumer confusion underpinned changes to the labelling directive 2000/13/ec due to enter into force last year that essentially flag up to the consumer possible allergens in a food product. the amendment heralds the mandatory inclusion on food labels of the most common food allergen ingredients and their derivatives: cereals containing gluten, fish, crustaceans, egg, peanut, soy, milk and dairy products including lactose, nuts, celery, mustard, sesame seed, and sulphites. there is no current cure for food allergy and vigilance by an allergic individual is the only way to prevent a reaction. the researchers from three allergy canters in zurich, odense, and milan took part in the study on soy allergy within the european union project faredat (5th framework programme). thirty patients (average age 26.4, 19 female) were included in the study. "the prevalence of soybean allergy in the general population is unknown, and few data exist on class i food allergy to soy in europe," explained ballmer-weber. the volunteers' blood were analysed for specific immunoglobulin e (ige), the predominant antibody associated with an allergic response, to soy, peanut, and soy proteins, bet v 1 and gly m 4. "none of our patients with soy allergy reacted to the starting dose of 2 mg of soy (1 mg of soy protein), which thus was the noael for our study population," wrote the researchers. sensitivity towards the soy was less that that observed with peanuts, they added, with the threshold doses more than one order of magnitude higher than observed in peanut allergy. "knowledge of the severity of symptoms of soy allergy and the threshold dose of soy is most important and might have a major effect on food-labelling directives," wrote ballmer-weber.

half of the reported food allergies amongst adults are not food allergies at all, says a new study from germany. according to a paper published in the journal deutsches ärzteblatt international , between 10 and 20 per cent of people see themselves as suffering from a food allergy, but the real figure may be half this. cornelia seitz from her co-workers from wurzburg university report that, of the 419 people with suspected food allergies tested in their study, less than 50 per cent actually had a ige-mediated food allergy.

with the implementation of eu allergen labelling regulations, more and more companies are producing testing kits to meet the demand from food processors. the allergen labelling regulations came into force on 25 november. it requires companies to label all pre-packed foods if they contain any of the 12 listed allergenic foods as an ingredient. uk-based biotrace international announced yesterday it plans to roll out several new allergen testing kits next year to meet the demand.

as europe prepares for tougher rules on allergen labelling, a new study could help food makers by slicing away the allergenicity of peanut products, reports lindsey partos. an estimated 4 per cent of adults and 8 per cent of children in the eu - the total population tops 380 million - suffer from food allergies, according to the european federation of allergy and airways diseases patients' associations.

reading scientific services ltd (rssl) has announced that it has validated new methods to test for the presence of fish and molluscs in food products. the company said with the addition of these new tests, it now has the capability to detect all 14 allergens that must be labelled if present in food products, under the provisions of eu council directive 2003/89/ec and its amendments; molluscs and lupin were added to list in 2007.

an allergen management and labelling guide, revised for 2007, has been published to help australian and new zealand processors recognise potential risks and avoid contamination. the guide provides an overview of regulatory requirements in both countries to declare food allergens on food packaging. as well as advice on good manufacturing practices, the guide also contains information on the risk assessment process referred to as voluntary incidental trace allergen labelling (vital).

food makers using potential food allergens in their formulations will benefit from the findings of a new food consortium, reports lindsey partos. an estimated 4 per cent of adults and 8 per cent of children in the eu - the total population tops 380 million - suffer from food allergies, according to the european federation of allergy and airways diseases patients' associations.
