Some Focussed Food Based Reports – Free online Information

Over the past view weeks I have come across several rather focussed processing reports which I thought it was worhgwhile to share here in a simple form. I believe the image tells you what its about and clicking will open the document. The documents I link will generally be technology heavy although there will be there industry issues covered in detail.

Factory in A Box

One of the interesting exhibitors at Gulfood Manufacturing  next week, is UFT who are promoting a Factory in a Box. While this seems to be an extension of UFT’s normal turnkey factory offering, it makes me think of a time in the late nineties in South Africa when container based “factories” were very popular.

FiaB at Gulfood Manufacturing

This was driven in South Africa by an excess of used containers, Corporate Responsibility’s responses to the new South Africa and arguments of low cost, simplicity and portability allowing units to be relocated in the event of failure.

In my experience this didn’t work out as the excess of used containers was soon depleted, the costs of installation and modification where higher than predicted and relocation turned out to be expensive because of transport and service connection costs. Containers have fared better as retail or service outlets than as food processing facilities.

Research shows that the principle of an “instant”, prefabricated or modular factory that can be quickly installed on site is attractive. There are still many examples, including those developed by multinationals. This definitely needs to be borne in mind and investigated when new processing is being evaluated.

Researching this has been an eye opener for me and it surely needs some research and evaluation to make sure we are not missing something by “going it alone”.

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.

New Milk Processing Technology For Rural Small Scale Farmers

Small scale farmers in rural areas with a a few cows can easily produce more milk than their family consumes, opening the opportunity to earn income by selling milk. However climate, lack of reliable energy and long distances make this an unreliable business. Introducing standard fresh milk handling technology does not work because of the costs are too high, the quantities too low and energy too unreliable. Other solutions such as increasing shelf life with fermented products and introducing the Lactoperoxidase System have there place but there is real demand for fresh milk.

This new system being introduced by Promethean Power could change this.

Chilling Milk Directly From the Cow for India s Dairy Farmers Modern Farmer

This is a mechanically simple system that is powered by local electrical supply which does not need to be consistent or reliable. Whenever electricity is available it is used to “charge” a thermal storage system, the system is then used to cool milk whenever it is available.

The thermal storage system consists of a cylindrical stainless steel tank, containing an unspecified phase change chemical in a heat transfer fluid. When electricity is available it is used to refrigerate the tank, freezing the chemical which absorbs large quantities of energy as it changes phase.

The simplicity of the system lies in the design of what they have termed the Rapid Milk Chiller. The milk is distributed on the top of the stainless steel tank, it flows over the total surface of the tank and is thereby cooled quickly. With gravity transferring the milk there are no pumps, pipes and controls which would complicate maintenance, be difficult to clean and require electricity.

There is also the potential to use any other alternative energy source e.g. solar, wind, biogas and biomass which can be converted into electricity.  

I like the idea and look forward to hearing about how it works out in practice.

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.

click the image to visit the website

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!

click the image to visit the website

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.

Fairtrade Shebeen Style?

FAIRTRADE has been a great success based on its rapid growth in turnover. There are, however questions that linger around the benefit to farmers compared to the turnover as well as other issues.

Shebeen generating funds to development

from: Shebeen
(click image for full story online)

A new idea that also allows the consumer to generate income for development is the Australian Shebeen. This food and drink outlet carries products that are linked to specific developing countries e.g. Tuskers from Kenya, Valdivieso Pinot Noir from Chile and Mumma Ho’s Vietnamese meatball.

It then distributes “100%” of its profits to “Not for Profits” in the country of origin of the food or drink bought.

I really like the idea, but it needs more information and transparency to understand its real benefit. Does $2 really go to development for each beer drunk as reported in one story?

  • what are profits – e.g. how are salaries, disbursement and reinvestment set
  • how are “Not for Profits” selected and what is the cost of this
  • how do normal developed country products contribute
  • is this a once off or is it scalable – i.e. when do we see an Australian she been in Soweto
  • I will be following up on this over the next while.
