Salmonella Results in the Recall of 550 Million Eggs

You have probably read of the recall of 550 million eggs in the USA because of a risk that they could carry salmonella. The article explains in some detail how it happens that eggs, which appear to be well packaged in a pretty impervious shell, come to contain salmonella.

Seems the salmonella either comes through the chicken, which is not affected by being infected, or enter through the shell from a dirty environment after they have been laid.

Well cooked or pasteurised eggs are safe, while foods that use raw eggs such as mayonnaise and eggnog are a potential danger.

Do Food Processors Give Consumers Less Than They Think.

The finding of this study reported on in Science Daily raises the question of how well the food manufacturers are, or want to educate the consumer to understand what their products contain and how this compares to other products.

So the consumer has understood correctly that the antioxidants (mainly polyphenols) in tea are good for them. Wanting tastier and more convenient sources of polyhenols they try and start to use bottled tea based beverages.

But what health benefit are the processors giving them – as always that depends, but a recent study by Shiming Li, a natural product chemist at WellGen Inc showed that bottled teas have polyphenols as low as 5% of a brewed cup of tea. This means that the antioxidant benefit of 1 cup of tea would be equivalent to 20 bottles of this tea.

Besides missing the health benefits bottled teas contain sugar, additives which means that drinking the large volumes to get the antioxidants can have other negative effects on the diet.

How many other products reflect a similar situation where the consumer is not really aware of what they are getting. Many fruit juice blend proclaim “100 % pure juice” not clearly noting the addition of water. Amarula Cream leads consumers to think it is produced from fruit collected in the community but in fact only a small fraction of the alcohol is. The actual quantity of sugar in carbonated beverages is not well understood. Organic, free range, corn fed and other similar terms related to “new age” foods are also not well understood and the certification of compliance is completely unclear to the consumer.

Think about it and email me your examples which I will publish!

How to Keep the Gas in the Champagne

A dynamic-tracking technique using IR thermography was used to visualize the cloud of gaseous CO₂ released when pouring champagne.

The findings of the research, illustrated by the graph above, were not that surprising – pouring gently along the wall like beer and chilling the champagne reduced the “loss” of CO₂.

The real question is what is left in the champagne and what level should that be?

Antioxidant awareness grows among consumers

An AOk Drinks survey reveals a growing understanding of antioxidants and identifies knowledge gaps for the industry to tackle.

The majority of people who purchase drinks such as AOk know that antioxidants are good for us, that we need to consume plenty of them to gain any health benefits, and that they fight free radicals, according to a survey by AOk Drinks.

Stuart Roberts, MD, founder and nutritionist at AOk Drinks, says: “We’re not surprised that people generally understand that antioxidants are good for us, but we were surprised at the level of understanding, which is higher than anticipated. Two-thirds understand that antioxidants fight free radicals and 65% know that they defend the body (cells) against oxidative stress.”

Red grape, cranberry, pomegranate and green tea are cited as leading natural ingredients that are packed with antioxidants by more than half of respondents. Kidney beans are a good source of antioxidants but this isn’t widely known (15%), as producers in this sector haven’t pushed this message during recent years, unlike in the juice sector.

Word of mouth marketing by leading antioxidant drinks brands has worked wonders for the industry, but it’s the consumers’ desire to regain control of their health and well-being that’s driving this awareness,” says Roberts. “I’m frequently asked to explain how antioxidants work, what free radicals do and how they can benefit different conditions.”

  • 66% understand that antioxidants fight free radicals.
  • Only 23.5% know that antioxidants provide support against injury and muscle damage for people who exercise regularly, yet 47% exercise for at least 30 minutes a minimum of three times per week.
  • More than half (53%) correctly identified that 3,000-5,000 ORAC units are recommended each day.
  • Red grape and cranberry were flagged as being high in antioxidants by 72% and 68% respectively.
  • 11% falsely believe bananas are naturally high in antioxidants.
  • Kidney beans, not previously marketed for their antioxidant content, were correctly identified as being high in antioxidants by just 15%, highlighting the importance of industry communications to educate people about the natural benefits of healthy ingredients.
  • 78% eat breakfast every day and 64% aim to eat five portions of fruit/veg each day. A further 54% cook the majority of meals from scratch.

The consumer survey of 102 British adults was conducted independently online by AOk Drinks in June and July 2010 ahead of the August rebrand.

1 Billion People Live in Chronic Hunger and I’m Mad as Hell

This is the title of a petition launched by the United Nations Food and Agricultural Organisation (FA0).

FAO_ FAO Home.jpg

(click the image to sign the petition)

I totally agree with this – it’s particularly disturbing if you think of how we “over consume” and waste food. So I have signed the petition and am suggesting you to do the same by visiting – log in, enter a few details and click the send button (you don’t even have to watch the video) its that easy.

You are NOT going to have 20 years of bad luck if you don’t do this nor get rich if you do! Just give it a thought and do what you think is right. FAO will present the petition to governments who will hopefully take note and action!

If you are interested in some of the background on the “waste and over consumption” I refer to, have a look at some of the stuff I have posted on the issue below.

Once you sign, you will be given a personal link that you can share with friends and family, and a personal impact map that shows how your message spreads around the globe. Share your personal link with as many people as possible. Come back often to check your personal impact map and witness the power of your social network. Thanks very much for joining me in this. It’s time we let politicians know that the status quo — 1 billion hungry people — is unacceptable.

Aseptic Filling Machine – Equipment Series

Aseptically packaged milk and juice has probably had the biggest impact of any technology in the beverages industry in the last 50 years.

One of the packaging machines of the Tetrapak, the company that started the trend by fabricating an aseptic machine, is pictured below.
