The Interview: Dr Mian Riaz

First published in International Aquafeed, January-February 2016

Mian Riaz PhD, is the director of the Food Protein R&D Center and head of the Extrusion Program and Graduate Faculty in the Food Science and Technology Program at Texas A&M University, College Station, Texas. Dr Riaz has given more than 235 talks in 50 different countries. 

He currently offers four short courses in the area of extrusion annually, two courses are in feed extrusion and two courses are in food extrusion. He has more than 22 years of research experience in his field. 

Dr Riaz is also an active member of the Institute of Food Technologists, American Association of Cereal Chemists, American Oil Chemists’ Society, Pakistan Society of Food Scientists and Technologists and the Association for the Advancement of Industrial Crops. 

This February, International Aquafeed Magazine and Dr Mian Riaz are presenting a one-day Short Course in Aquaculture Feed Manufacturing. Speakers from industry and academia will give lectures on the latest technology in aquafeed extrusion and related equipment on February 14, 2016 at the Abu Dhabi National Exhibition Centre. This one-day seminar will cover the specialist areas of manufacturing aquafeeds. 

IAF recently spoke to Mian Riaz to discuss both the one-day course in Abu Dhabi and to collect his thoughts on the extrusion industry of today.   

You are speaking at the forthcoming extrusion course in Dubai, which topics will you be discussing? 
At the event in Abu Dhabi, I will be talking in general about introduction to extrusion. Since several people have no idea about the basics of extrusion, its principles, function and types of extruders which are available in the market. I will also provide some general rules of thumb and basic guidelines for when someone needs to purchase a new extruder. 

Can you provide our readers some information about your duties and responsibilities as director of the Food Protein R&D Center and head of the Extrusion Program and Graduate Faculty in the Food Science and Technology Program at Texas A&M University? 
As head of the extrusion program, I oversee all the activities in the area of extrusion, which includes research, industry work, short course and special training in the area of extrusion. 

What do you consider to be the key developments in extrusion since you became involved in the industry? 
There are several new developments in the last 20 years. We used to have volumetric feeder, and now we have loss measurement in feed systems that is much more accurate. There are several improvements in pre-conditioners, from single shaft to double shaft to differential diameter shafts to high intensity pre-conditioners. All of these improvement help to better mix, cook and hydrate the raw material for cooking. Now we have conical screw and very unique dies. 

Was 2015 a particularly busy year for you, and what were your highlights of the past 12 months? 
Yes, we conducted four courses in the area of extrusion and have has a record number of participants attend our courses. We saw a major jump in the number of participants enrolling on aqua feed extrusion short courses. 

Has the extrusion industry encountered any major challenges since you have been involved with the extrusion process? 
Extrusion manufacturers are very progressive and listen to the industry so they are able to tailor their equipment to meet the needs of their customers. This industry faced a major challenge for food and feed safety. Extruder manufacturers overcame this challenge by improving their hardware and processing parameters accordingly. 

Are you looking forward to seeing any of the other speakers or exhibitors at this year’s show, if so, which ones are you most interested? 
There will be three other speakers at this course and I will be looking forward to meeting all of them. They are, Mr. Joe Kearns vice president for Aqua feed Division, and Dr. Ramesh G. from Wenger and Dr. Abdel-Fattah M. El-Sayed, professor - Oceanography Department, Faculty of Science, Alexandria University, Egypt 

There is such a vast array of events coming up over the next 12 months, but which are the events are you most looking forward to? 
Most of the events are related to general livestock feed, however, I am looking forward to Middle East VIV, Victam and ILDEX. 

In your opinion, what is the most vital piece of equipment available to the modern extruder? 
There are several pieces of add-on equipment that have been made available by the extruder manufacturers. But in my opinion Back Pressure Valve (BPV) is one of the most vital pieces of equipment currently available to those, like myself, who are involved in the extrusion industry.
