This is a link to an equipment supplier, but makes no comment/judgement on the company or its equipment. It is only posted as it seems to contain interesting technical information.

Free Food Science Journalsn

DIGIVU focusses on curating the mass of online food processing and alternate enegy information for users of the site. There are, however, sources of information that the user should be following themselves rather than waiting for them to appear on the site.

I will be covering these in the next while and hope you will be able to link to them via free subscription or RSS, so that they become part of you reading.

The first is a journal edited by Ruth Oniang’o that focuses on nutrition, food processing and conumers in Africa.

The next is the review journal of the Institute of Food Technologists (IFT) published by Wiley Publications.

This journal is very different from AJFAND focussing on depth reviews of food science and food safety with a global rather than African Focus.

The third journal for this post is the Journal of Food Science and Technology, which is Wileys open acces journal in the food processing industry. Open access journals are free to access for all and normally require the author to cover the costs of publication.

Both the Wiley journals offer RSS feed or email notifications to alert the reader to neweditions. The AFJAND journal unfortunately has no built in system for alerting readers to new journals. The reader therefore needs to subscribe to a service such as ChangeDetection.com (which is the only one I have tried) to be notified of changes to the website. Two articles shown below review a number of these services.

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.

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. 

Another Source of Free Online INformation

My previous post on sourcing free online information omitted the in house information of major public organisations.

EPA technical Information on Breakfast Cereals

from: US EPA
(click image for full story online)

The flowsheet is an extract from a document by the Environment Protection Agency on Breakfast Cereal Processing. The 11 page document describes raw materials, products and 6 processes in detail. It has a short section on what emission controls are required.

The information is prepared as background for it field officers and is downloadable from their website.

I have seen similar information on useful food processing information from organisations such as USDA, US FDA, Shipping Associations, Firefighters and Equipment Suppliers. Its well worthwhile identifying these sources.

Free Food Science & Nutrition Information

Food Advisory Consumer Services (FACs) say that their site “is primarily intended for consumers and other interested parties seeking balanced and scientifically correct information on some of the many contentious and emotive issues which perennially appear in the media.”

The tone maybe shows that they are very much the voice of science and not much interested in what people experience and anything alternative. This doesn’t suit me very well as I am able to detect MSG in food by quite a violent reaction – which their article very much dismisses!

But still there is good information in the articles they have written and posted as well as in their list of links. So I recommend them!

Free Broad Technology Information Source

HYFOMA (European Network for the Manufacture of Hygenic Food) maintains a site which aims to centralise and coordinate literature from food equipment manufacturers.

The website is funded by food equipment manufactures and states that it intends to capture all available information but seems to be still in the process.

Articles range from full reviews eg Ohmic & Induction Heating for Microbial Inactivation to pretty simple outlines. Articles are basically focussed on products or technologies.

Although this site is still building and you may find articles that are notyet available or only in a foreign language, its still worth a look as its such a large source of free information.



Food & Process Engineering Technology – Free Online Information

I, as a chemical engineer, am really excited to find a book like this on line and easily usable.

The book is on SCRIBD which has been called the youtube of documents. Although posters on SCRIBD can make their posts downloadable this one does not, so you can only stream it.

The clip below tries, but fails, to show the blend between quantitativeness and practicality.

Rather, if you are interested in Food Processing and brining comprehensive calculation into it go and see the book.

The Chapters are titled.

    • Problem Solving Tools: Dimensions and Units, Algebraic Equations, Graphs and Coordinate Systems
    • Mass and Energy Balances: Conservation of Mass, Conservation of Energy
    • Physical Properties of Food and Biological Materials
    • Textural Properties of Food and Biological Materials
    • Fluid Flow: Fluid Characteristics, Fluid Statics, Fluid Energy Balance (Bernoulli Equation), Fluid Friction Loss, Pumps and Fans, Non-newtonian Fluids
    • Heat Transfer: Conduction, Convection, Radiation, Heat Exchangers, Thermal Properties
    • Thermal Processing
    • Psychrometrics
    • Drying and Dehydration: Equilibrium Moisture Concepts, Drying Theory and Models, Drying Applications
    • Refrigeration: Equipment sizing, Refrigeration load, cooling time
    • Biological Product Preservation: Deteriorative Mechanisms, Storage Fundamentals, Thermal Sterilization and Preservation

I am not sure how this book is able to appear online, but since its there why not have a look! Either click the clip above to open in your browser or click below to stream here.

Science in Africa – Online Information Resource

Here is a really good online resource – it covers a wide range of scientific subjects from an African angle and also periodically presents really practical series with a do-it-yourself flavour.


Science in Africa, Africa_s First On-Line Science Magazine, Home Page-1.jpg


For example there was a series on essential oils including processing and how to produce alcohol from waste on a cottage scale.

Agribusiness Information – West Africa Trade Hub

I always feel good when I see what looks like real useful information that is available to African entrepreneurs for free!

The West Africa Trade Hub is funded through and managed by the USAID Regional Mission for West Africa.

This is packed with useful information from trade directories to export and business guides, country and sector analyses to product reports and transport analyses to conferences and workshops.

There are two other hubs for East and Southern Africa, but these do not yet have the breadth of information presented by the West African Hub.

What I would like would be to hear from people who have used the West Africa Hub – is it as good as it seems? Leave a comment or email me here.

If so I think we could start to support and encourage USAID, the main funder of the hubs, to speed up the development of the other hubs.

Web to Email

I am aware that many of the people who could benefit from the information I am publishing have difficulty in downloading files from the INTERNET due to the cost of being online. I in fact mentioned this in a recent blog which was based on a very practical drying manual which can be downloaded.

While GOOGLE says they, with HSBC, are going to bring cheap satellite based INTERNET connectivity to Africa, this will take time and we still need to see what options exists at present.

One solution is offered by Web2Mail.com.


from: Web2Mail
(click image for full story online)


The service allows you to receive any webpage as an attachment to an email. So long as you have a pop mail account getting the information into your computer will be much quicker than going online to download the information. This will be particularly useful where you want to download an online document.

There used to be many of these kind of services but they have mainly closed down claiming that they were not being used effectively.

We are investigating the possibility of the Blog supplying documents featured here by email, on request from users. This, however, requires that we get permission from the owner of the information.

Another thought is that seeing that most of what is discussed here essentially has a developmental focus, it should be possible to get assistance is sourcing documents from extension officers and NGOs who have better connectivity.
