Unrefrigerated caramel apples may contain Listeria

Researchers from the University of Wisconsin-Madison Food Research Institute have highlighted that caramel apples should be refrigerated to prevent the development of Listeria and the source of the contamination is puncturing by the stick which is inserted into the apple. The research was conducted in response to the 2014 Listeria outbreak in America which saw 35 people being infected and at least 3 people killed. 

The researchers purchased 12 dozen Granny Smith apples and contaminated them with a mixture of four strains of Listeria. Sticks were inserted into half of the apples and all the apples were dipped into caramel. Half of the apples were stored at room temperature (25 degrees Celsius) and the other half were refrigerated at 7 degrees Celsius. The apples were measured for Listeria growth every few days.  

Significant quantities of Listeria developed in the apples stored at room temperature with sticks in them after just 3 days whereas it took 2 weeks for Listeria to grow on the refrigerated apples with sticks. As for the apples without the sticks; the researchers discovered that Listeria growth was apparent on the unrefrigerated apples after one week whereas those that had been refrigerated experienced no Listeria growth.


Drinking cranberry juice may be good for the heart

Research presented at the Cranberry Health Research Conference in Wisconsin US has studied the effects of drinking cranberry juice on cardiovascular disease and bone health.

10 healthy men between the ages of 18 and 40 were given 450ml of sweetened cranberry juice made from concentrate and water at levels varying from zero to 117 percent juice equivalent. The results demonstrated significantly improved blood flow and vascular function in the men after drinking the cranberry juice. The study found that the improvements in vascular function were dependent on the dose.


Increase in demand for organic packaged food

According to figures published by Mintel data, France was the most active country in Europe for organic new product development between the years of 2012 and 2014 with a quarter of product launches bearing an organic claim showing there is a lot of potential within the packaged organic food category. A 12.3% increase in sale for organic packaged food value was seen in Italy between 2010 and 2015. It was clear that consumers in Italy and France are prepared to pay extra for organic and higher quality products.


Food waste a focus for the European Commission at EXPO Milan

Food waste is set to be a focus at EXPO Milan as it is believed that date marking is not understood clearly by European consumers.  The focus on food waste comes in response to the Flash Eurobarometer survey which highlighted this finding. Two-thirds of those surveyed mentioned that better food management at home is essential in reducing food waste and almost half highlighted the need for clearer information around food labels and date marketing.


Project finds how to turn starch production waste into protein supplements

An EU funded project BIORICE has discovered how to form protein supplements from starch production waste. The researchers claimed that the proteins can be broken down into smaller peptides which can be fractionated by membrane technology into different sizes. These may prove useful in nutritional supplements. The end product looks like milk powder and 100 to 200 grams of the peptides have currently been successfully produced. 

We have expertise with a wide of ingredients from carbohydrates and high potency sweeteners to fat replacers, proteins, fibres and functional ingredients.


Research shows outbreak of Yersinia pseudotuberculosis O:1 is associated with raw milk consumption

Recent research has investigated the 2014 outbreak of Yersinia pseudotuberculosis in southern Finland to establish its source and extent to apply appropriate control measures to prevent potential future exposure in southern Finland.

In the univariate analysis from studying 93 persons from 30 households completing a questionnaire, it was clear that raw milk was the only food item significantly associated with the illness. The odds ratio (OR) of Yersinia pseudotuberculosis increased as the volume of raw milk increased. 

The study results found that healthy adults can become infected by consuming contaminated raw milk and milk should be heated before drinking.
