How Big is Food Waste?

Food Waste is the food which is produced  but not eaten, because it is either lost or discarded.

Meat Loss Infographic

Shockingly the meat lost (and the greenhouse gas has still been produced) is equivalent to 75 million cattle a year. This information is that of the United Nations Food and Agricultural Organisation from 2013. Although there may have been some change given the efforts that have been made, I am sure the figures are still substantially as shocking as they were then.

The picture for other products is just as bad – you can click the images to reach the infographic online, where it is more legible.

Keep Your Pinch of Salt Handy

As it becomes easier and easier to publish information in a credible looking way, I wonder if its for the good or not?

Patented__Pixie_Dust__Sterilization_Method_Introduced_for_Aseptic_Packaging_-_Quality_Assurance___Food_Safety


In November 2015 there were lots of stories, many very similar to each other, published on Pixie Dust. Only one that I saw really remarked on the technology and tried to evaluate it, the others seemed to cut and paste what I suppose was a press release. For me it “sounds to good to be true” – you add a small amount of a cheap substance which sterilises the container and its contents in a fail safe process. There is mention of a patent with more patents being developed and Performance Packaging looking for international partners. But what exactly is the patent and how far was the process of finding partners.

Even so the headlines use words like launched, introduced, offers, solution …… leaving readers with the impression it as available. But 6 months later there seems to have been nothing for months and no one has reported on follow up.

I am following up to try and see where this interesting technology is now.

The History of Food Processing

This short article, with a large list of references, is a guide in the John Hopkins University’s Teaching The Food System project.

The short outline is informative and covers in outline many of the factors that lead to the food industry of today, linking these to references provide more in depth information. There are also illustrative slides that accompany the text.

Meat Processing for Small Businesses – Free Online Information

Here is another example of valuable technology information that is available for free from the FAO.

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.

 

Food Processing Pages With The Apple Look

My posts on this blog for many years have been written on Apple computers and tablets. I am very much an admirer of Apple and its minimalist approach to design of both hardware and applications. They introduced the clean, light and almost austere look to computer screens which has since become a kind of standard part of succesful user interfaces. So I was struck by the new site of Alfa Laval.

Apple Like Website

To me its really beautiful and very Apple like. However at the same time it has some really good content which I am likely to share in future posts. For example this flowchart of a milk pasteuriser

This flowcharts are interactive linking to father information about the equipment including specifications, diagrams and even animation videos.

As usual I need to note that this information is linked to the equipment of Alfa Laval, which I am not passing any judgement on oe recommending. I do, however, believe that the value of clear information like this outweighs the fact it is linked to the supplier

France Legislates Against Food Waste

I have for some years been speaking and even publishing on food waste. Its not only what gets dumped that is wasted but the land, inputs, storage and distribution used that is wasted.

France have put the onus on supermaarkets to move to zero food waste by compelling them to use what could become waste food for social projects, animal feed, biofuels or compost.

Sustainable Biogas in Meat Processing

This Australian article shows the state of the art in biogas recovery and consumption.

While biogas has been around and used for centuries, this plant focusses on increasing the sustainability by controlling the anaerobic digesting more efficiently and managing the gas storage and consumption.

The “Green Energy Orb” is just a methane storage tank, but then greenwashing is allowed!

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.

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.
