As the Barley and Malting Quality Biochemist at the Australian Export Grains Innovation Centre (AEGIC) in Western Australia, Dr Yousif undertook a malt industry relevant research project in collaboration with malting plants Cargill Malt and Barrett Burston Malting.
Concurrently he delivered the OndeaPro enzyme cocktail barley kernel brewing research innovation project (2014-2016).
The aim of this project was the use of exogenous enzymes to make beer directly from barley as an alternative to the use of malt. The outcome of this project was the successful processing of unmalted barley into beer, elimination of malting costs, and benefits such as lower beer dimethyl sulphide (formed during malting) content. The significance of this project is lowering the carbon foot print of the malting and brewing industry which contributes to the national and international effort in the reduction of greenhouse gases.
Dr Yousif's research is focused on making a difference in food product development, processing, sensory analysis and food nutrition.
He has had considerable experience in functional food component research and product development into everyday food consumables such as bread and pasta, as well as related health studies. His research is specifically related to cereal/pulses (barley, sorghum, wheat, soybean and adzuki bean) quality and the development of innovative cereal/pulse foods containing elevated levels of health functional components such as resistant starch and polyphenolic antioxidants which are key areas of research for nutritional health.
Using his knowledge in ingredient functionality, food chemistry and quality attributes Dr Yousif has developed a sorghum flatbread food product. To enhance the health potential of traditional grain foods he developed a new low glycaemic index, antioxidant rich flatbread by reformulating the flatbread, using high antioxidant/high resistant starch sorghum. This project led to the development of novel sorghum flatbread and two scientific publications.
Dr Yousif used an inter disciplinary approach to carry out a food science project title “Incorporation of Bovine Dried Blood Plasma (protein) in Biscuit Flour for the Production of Good Quality Pasta”. This industry relevant food science innovation project involved undertaking food product development, food processing, sensory analysis and food chemical (protein, fat, carbohydrates, dietary fibre) and physical (Minolta colour measurement, Texture Profile Analysis) analysis. The significance of this project is the development of a shelf stable, nutritious product that may be utilised internationally in times of natural disaster and in lower socioeconomic areas. Furthermore, this project exhibits his ability to innovate though the use of two low value protein sources - bovine blood plasma and wheat proteins to develop a nutritionally value-added pasta product as well as my ability to write and publish the project in a scientifically referred journal.
Collaboration with the Australian Commonwealth Scientific and Industrial Research Organisation (CSIRO), project titled: The effects of post-harvest storage on soybean physical and chemical properties.
To successfully deliver this project Dr Yousif formed a collaboration with CSIRO grain storage research unit at Black Mountain Canberra. Outcomes were the recommendation of the optimal postharvest storage conditions (temperature, humidity and time) for optimal soybean processing quality thereby enhancing export market end user satisfaction, increasing demand for Australian soybeans and ultimately enhancing farmgate returns. This project also resulted in one CSIRO report and two refereed publications as single author.
Dr Yousif carried out production line process analysis of canned cereal meat analogue dog food.
The aim of this work was to troubleshoot the issue of high levels of fines in the final canned product. He studied the food processing line in order to gain an understanding of the process outcome, fault implications and determine related required actions to resolve the defect. He identified the problem, which was due to the extruded analogue meat biopolymer proteins having not coagulated properly in order to develop the correct cross linkage such as cysteine-cystine disulfide bonds. Due to this fact the cereal analogue meat product was still friable due to being at too high a temperature when exiting the oven, being diced and entering the food transfer pump hopper.

- To investigate, document and report on opportunities in the growing non-alcoholic malt based global beverage markets. Currently to produce non-alcoholic malt drinks, wort is fermented and back distilled to reduce the alcohol level to below 0.5%. Because of fermentation, most nutrients are lost due to the removal of the biomass which is converted to nutritional products such as Vegemite. Development of innovative non-alcoholic flavoured and carbonated malt drink prototypes is appropriate for consumption as a nutritious non-alcoholic drink suitable for pregnant and breast-feeding women; people who do not drink alcohol and for export markets such as, American, European and African continents, Middle East, Far East and the Indian subcontinent.The aim of this study is to;Develop a non-alcoholic flavoured and carbonated drink from malted sorghum.Understand the nutritional quality of the sorghum malt non-alcoholic flavoured drink in relation to the retention of the sorghum grain nutritional properties.Prepare a business case to produce non-alcoholic malt drink (potentially in partnership with a major brewing company).Understand the related chemical composition, physical properties and sensory qualities of the non-alcoholic flavoured malt drink.
