Ice Pigs in Food Processing?

Talking of pigs in a food processing plant brings to mind an abattoir or a plant in a really sad state of cleanliness. However, this pig is actually behind new operations in Food Processing that improve hygine while saving capacity, chemical, product and water. The principle is explained in this video

I remember first hearing of pipeline pigs when the petroleum pipeline from Durban to Johannesburg was installed. This was basically a rigid plug with the diameter of the pipeline that is pumped through the pipeline between two different fluids. The novelty here is a flexible plug which can even separate fluids in a heat exchanger. The second video demonstrates the process although the transition back to process flow is somewhat spoiled by a demo failure.

While both this videos feature the Food Process Engineering company GEA, this is not to imply they are the only or a preferred supplier. The links below are to other online starting points, but it would be wise to approach your suppliers for further information.

A Collection of Sorghum & Millet Information

If you need to get to know about Sorghum or Millet or want to get some of developments, this conference publication could be very useful.

Website presenting papers of the Afripro 2003 Conference

Unfortunately this conference is now 10 years old so doesn’t present the very latest state of the industry, but does contain two good reviews which are always relevant and some of the science of the time around food products, nutrition, plant breeding, sorghum based polymers and consumer preferences.

With international researchers like Professors Belton, Rooney and Taylor one can rest assured that the standard and focus of the work was of the highest standard. The web site presents a wide range of papers as well as the questions arising and the way forward through focus group and a prioritised list of research needs.

This conference was the output of a development funded project, so has no direct project follow up. However, there has surely been more work in the technology areas identified and maybe there were activities in ideas/groups born from the conference. I have not been able to find a collection of this type of information and would be interested to hear about your experiences and share further information here.

Food Product Innovation

This is another of the many manuals by FAO. This one discusses product development, although in a someone theoretical way.

click the image to visit the web page

The manual is broad, covering the following topics:

There is a lot of good information in here although for my liking its a bit theoretical and maybe it could do with some more interesting case studies.

It is, however, worth downloading and reading. It is 35 pages and was published in 2006 so is up to date and comprehensive.

Do Germans Spend 20 Times More Than Chadians on Food?

Hungry Planet, a recent book by Peter Menzel and Faith D’Aluisio, presents the food consumption of households around the world. The results are presented in the form of a picture of the family and the food they ate in a week, just like this German family.

In each case the total cost of the food is given (in this case $500) as well as demographics of the country and some information on favorite foods. Besides just being interesting and revealing eg this German Family drinks 4 bottles of wine in the week while the French family appears to drink only one, it gives a view of food culture an food processing.

Revealing and concerning is the difference between first and third world countries and in particular, Central African countries. The family from Chad spends only $2,50 on food, just a 20th of the German Family!

This is quite startling, although the environmental impact is probably even more interesting given the almost complete lack of processed food, besides post harvest processing, and one way packaging in the food of the Chadian family. While the German family shows that in a week they used around sixty glass, plastic and board beverage containers.

Not much scope for a Food Processor in Chad!

The answer to the question in the title is that we can’t tell from these single images. However, we can be sure that the general differences highlighted are an indication of the food culture differences. We also know from the research on waste, that a significant fraction of the food (maybe a quarter) shown in the German home is probably wasted, while very little of that reaching the Chadian household is.

The Dark Cider in a Black Bottle for South Africa

Savanna cider joined Amarula Cream to become second largest in its alcoholic beverage class a few years ago. This was achieved with Savanna Dry and Savanna Light which are now complemented by Savanna Dark.

This appears to be a golden cider in a black bottle – wonder if this will bring it some further success in Black Africa?

Using Food Science and Technology to Improve Nutrition and Promote National Development

This is an interesting and detailed paper presenting detailed information on the processing of traditional foods.

Chapter from an IUFOST publication

from: IUFOST
(click image for full story online)

The paper concludes that the existing small scale processing is important to food supply, food preservation and employment.

It finds that the expansion of the production of these traditional foods would make business sense, this has been hampered by the normal culprits – access to technology, poor management, lack of funding and low profit margins.

The paper presents information on the mechanization of gari, the production of instant yam flour and flakes and the production of traditional products including soy-ogi, dawadawa, kilishi and cheese.

The article has a detailed list of references.

Gentle Drying of Fruit and Vegetable Purees in a BIRS Spray Dryer.

Here is another story looking at product development focussing on premium products which avoid heat treatment in processing.

The BRIS process uses ambient temperature air which has been dried using heating and silica gel to a few percent relative humidity, in a counter current drying tower.

This application by Naturex, a French company more focussed on natural ingredients for the food & beverage, nutrition and health and personal Care industries, is a first for them. The products main selling point appears to be their good organoleptic properties and their ease and quality of reconstitution.

Production of Foods From Marula, Monkey Orange and Embee

This paper looks in some detail at the production of juice, jam, jelly and muffins from Marula, Monkey Orange and Embee.

The results are good and show a high degree of acceptance for the products made.

However, having just been looking at some of the attempts to commercialize this type of food in South Africa, it is the commercialisation which is the difficult step. Giving recipes and training to communities is unlikely to create jobs unless a focused entrepreneur gets hold of it.

Wara – Traditional Cheese of Nigeria

Timbuktu Chronicles describes this traditional cheese made from cows milk with a leaf extract from the Sodom Apple (Calotropis procera) tree. The leaf extract performs the coagulating role, normally played by rennet.
