The manual covers meat science, processing, processing equipment, ingredients and formulations in detail with little mention of other business topics such as distribution, marketing and quality. The book is some 400 pages long is well illustrated with drawings and photographs.

All You Wanted to Know About Cocoa & Chocolate – Free Online Manual

This is an extremely detailed manual which is interesting just to scan but presumably really valuable to the manufacturer.

Will Food Waste Drive New Date Labelling

 

The last several years have seen a marked change in the understanding of food loss across the complete food value chain which has come as a shock to many.

Solving the problem is definitely not a simple matter as many factors ranging from improved crops to household meal planning and supermarket shelf management to pest control will impact on the loss.

A recent paper called for a “move toward uniformity in date labeling, thereby decreasing confusion among stakeholders and reducing food waste.”

The report identified Date Labeling Uniformity, Regulatory Enforcement, Consumer Education and Indicator Technologies as important focus areas. The paper presents information from a number of studies, the essence of how well or badly consumers understand date labling of food appears near the end of the infographic at the head of this post.

While the technological reasoning behind some of the Indicator Technologies being developed is sound, the work required to get the consumer to understand and use such technologies will need attention. If a temperature logger system is linked to a microbial growth model and used to predict the time to the end of a safe life understanding becomes even more difficult. Too much reliance on what the technology tells them may lead to consumers ignoring more traditional indicators of deterioration like acidity, smell and consistency.

So its an interesting time ahead. This might not be effecting smaller food businesses in sub Saharan Africa, but is interesting and helps the entrepreneur keep an eye on where it will need to move at some time in the future.

Smaller Bakery Process and Equipment – online video

After the previous post which showed an industrial baking operation, here are a few videos that show smaller scale baking. The first is a slightly mechanised bakery that is producing standard non industrial breads.

The next video is of a small artisinal bakery – these are becoming popular where health, environment and simplicity are traits that consumers are willing to pay more for.

The third video, published on YouTube by Vincent Talleu, shows his love for the tactile aspects of baking.

Please let me know if you find these videos useful or merely a waste of bandwidth and I will adjust my posting appropriately.

This video from Grain Chain gives a good overview of how a large industrial bakery works.

Amazing Free eBook on Solar Drying Available Online

The book entitled Solar Drying: Fundamentals, Applications and Innovations is some  pages long and covers a range from fundamentals to case studies.

The following chapters are essentially stand alone books covering a range of topics.

  • Principles, Classification and Selection of Solar Dryers
  • Solar Drying of Fruits and Vegetables
  • Solar Drying of Major Commodity Products
  • Solar Drying of Fishery Product
  • Quality Characteristics of Solar Dried Products
  • Recent Advancements in Solar Drying

Its really worthwhile getting this book to keep as a reference.

Should Sun Drying be Rejected as a Food Unit Operation

Papers describing food drying techniques normally list the obvious contamination risks of drying in the open air as a major disadvantage and and based on this dismiss its application. However, the large volumes of food that are sun dried every year and the savings in energy and capital bely this quickly reached conclusion.

Searching the literature and regulations doesn’t give any guidance on the advisability of establishing a new sun drying business.

However, the two videos below show the large scale use of sun drying and the associated technologies applied at Cecilia’s Farm, near Prince Alfred in South Africa.

It seems that the critical point about the sun dried business they run, is that all fruit is washed before further processing and or packaging. Arguably this makes it comparable to fruit which is often not peeled, packaged salad and leafy vegetables. These are grown in the same environment and simply washed before eating.

The massive advantage of sun and to a lesser extent solar drying is that they produce shelf stable foods with minimal environmental impact and low processing and packaging costs.

Small Scale Popcorn Equipment

Here is a business that can be set up with quality equipment at an affordable cost.

This is a manual oil kettle based popping plant which can produce 55 kg/h from the two poppers. More poppers can be combined with a larger sifting and cooling table. Poppers can also be combined in automated units.

Real Good Cheese and Dairy Information

The website of Dairy Science and Food Technology, an information and consultancy service for the food industry, provides useful and applicable information, calculators and reports which are surely of great use to the dairy processor. 

 Science and technology of milk and dairy products

The website was established by Dr Michael Mullan who is CEO of the Dairy Science and Food Technology consultancy.

Originally the site was intended as a project aimed at exploring the use of the Internet as a means of communicating with students. Over the years the site has grown and contributions are now invited from the wider scientific community and industry.

DSFT gets around a million ‘hits’ a year and there are hundreds of links back to the site.

The content of the site is illustrated by the navigation menu which includes topics like Cheese Yield, Food Models, Lactic Bacteriophages, Calculators, Links, Packaging and Labelling, Writing Tools, Thermal Processing, Ice Cream and Probiotics.

The nature of information is illustrated by the screen grab below from the Cheese Quality page.

To me this kind of information on the INTERNET is what we need to access, not the generic marketing type information that abounds. Please share the information you use by commenting on this page. 

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.
