The Food Chemistry lab at Heriot-Watt University in the School of Engineering & Physical Sciences is seeking to hire a postdoc in the area of oleogelation for the replacement of animal fats in vegan cheese and bakery products.

This project will follow on from fundamental research on the structure stability and formation of food oleogels funded by UKRI (EP/J501682/1; BB/M027449/1) and preliminary work on their application in vegan cheese and shortcrust pastry . Here we will further investigate the scale up of this technology to replace saturated fat in vegan dairy applications and pastry for bakery products. Saturated solid fats are added to formulated foods to give structure and to carry oil soluble flavours and vitamins. However saturated fats raise blood cholesterol levels and thus are a risk factor in cardio-vascular disease (CVD). Solid fats are predominantly of animal origin and so are also not suitable for vegetarian and vegan products. This can be circumvented by adding palm fat or coconut fat in vegan products. This does not solve the saturated fat issue and introduces a further complication in that palm oil has a poor sustainability image with consumers due to destruction of native habitat to plant oil palm plantations. Currently vegan cheese relies on coconut or palm oil for structuring plasticizing and texture modification whereas palm fat is added to peanut butter to give a solid texture. Oleogelation is a potential solution to both saturated fat and sustainability problems. An oleogel is formed from polyunsaturated liquid oils by adding a gelling molecule for example a mixture of plant phytosterols or other low molecular weight gelators or polymeric gelators such as proteins. We have studied oleogels as fat replacers for the past ten years and have developed a deep understanding of the underlying physico-chemical principles for gel formation. For example phytosterols self-associate into nanometer diameter tubules that then further associate to form a network gel that traps the oil in the gel pores and solidifies the liquid oil. Small angle neutron scattering studies we have carried out at the Institute Laue Langevin in Grenoble have confirmed the tubular structure and allowed us to characterize the structure as a double-walled hollow tubule. Any vegetable oil can be solidified using this method negating the need to use non-sustainably sourced solid plant saturated fats. Using such technology in vegan dairy analogs and pastry would make them not only more sustainable but also healthier as they would contain only polyunsaturated oils.

We are seeking candidates for a postdoctoral position in the Food Chemistry group in the Institute of Biological Chemistry Biophysics and Bioengineering. Applicants should hold a PhD in Food Science Chemical Engineering Biochemistry Chemistry Physics or a related subject. Experience working with foods (or other soft materials) is not essential but would be beneficial. Similarly although the project will involve significant rheology texture analysis and some taste panel studies experience of these although beneficial is not mandatory as full training will be given. Of more importance are the desire and ability to apply fundamental knowledge to real world problems excellent verbal and written communication skills and the ability to transfer knowledge to the industrial collaborators in this project.

Key Duties and Responsibilities

Responsibilities

• Manage projects in terms of the planning of experimental program carrying out experiments curating the data and liaising with the industrial collaborators.

• Develop the project by suggesting innovative solutions.

• Contribute to the writing of follow on projects.

• Collaborate in and/or lead in the preparation of scientific reports and journal articles and present papers posters and talks.

• Act as a source of information and advice to other members of the group on methodologies for oleogel incorporation

• Represent the research group at meetings and conferences either with other members of the group or alone.

• Mentor junior members of the group (PhD students or undergraduate research students).

Education Qualifications and Experience

Essential Criteria

The candidate will:

• Hold a PhD or be near completion of a PhD in Food Science Chemical Engineering Biochemistry Chemistry Physics or a related subject.

• Experience working with foods or other soft materials.

• Familiarity with small angle oscillatory rheology and large deformation texture analysis.

• Familiarity with taste panel training setup and execution.

• Experience working in or with the food industry particularly in the meat and dairy analog space.

Desirable Criteria

• Be able to demonstrate competence and success in their PhD research (and postdoctoral work if appropriate) e.g. as judged by publication in high quality peer-reviewed journals. Evidence will be sought of a deep understanding of the applicants previous fields of research and evidence of independent intellectual and practical contributions to previous research projects.

• Possess excellent communication skills including the ability to lead the writing of journal articles present research proposals and results and represent the research group at meetings.

• Show an ability to work supportively in a laboratory environment and to supervise and mentor junior co-workers.
