Understanding the Role — What is Flavour Creation?
Many applicants are unfamiliar with what a flavour creation laboratory actually does. Here is the context that will help you apply and interview with genuine understanding:
Flavour creation is the science and art of developing the taste and aroma profiles that manufacturers add to food and beverage products. When a food company wants to launch a new mango-flavoured drink, a smoky barbecue crisp, or a vanilla-infused yoghurt, they do not create those taste profiles themselves — they partner with specialist flavour houses like IFF. IFF’s Flavourists — highly trained specialists who spend years developing their palate and technical knowledge — design and compound flavour formulations using a library of natural and synthetic aromatic compounds. These formulations are then tested in the actual food or beverage application, refined through sensory evaluation, and ultimately approved by the customer for use in their finished product.
As an intern in the IC&D team, you will be supporting this process — from sample preparation and raw material handling through to participating in sensory evaluations and contributing to project documentation. You are not observing from a distance — you are part of the team that makes this happen.
What You Will Be Doing
- Supporting Flavourists and Designers in flavour applications, compounding, and sample preparation — handling raw flavour materials, weighing compounds, and preparing samples according to formulation specifications
- Assisting in the development and execution of projects for both local South African customers and global IFF clients — meaning your work contributes to flavour solutions that may be used in products sold across Africa and internationally
- Participating in product tastings, evaluations, and sensory analysis activities — developing your palate and your ability to articulate sensory characteristics in technical language
- Preparing and maintaining laboratory samples, raw materials, and documentation — ensuring traceability, accuracy, and compliance with IFF’s quality and safety standards
- Following and executing tasks assigned by IC&D team members with precision and attention to detail — laboratory accuracy is non-negotiable in flavour creation
- Collaborating with cross-functional teams — including applications, quality, regulatory, and commercial functions — to support innovation and product development initiatives
- Learning and applying best practices in laboratory safety, quality management, and regulatory compliance
- Contributing to ongoing continuous improvement and innovation efforts within the IC&D team
Key Requirements
Essential:
- Currently pursuing or recently completed a degree in Food Science, Chemistry, Biochemistry, or a closely related field
- Strong genuine interest in flavours, food applications, and product development — this is not a role for candidates who see food science as a generic qualification without specific career direction
- Basic understanding of laboratory practices and safety standards — you must be comfortable in a professional laboratory environment from day one
- Detail-oriented with good organisational and documentation skills — flavour compounding requires precise measurement and meticulous record-keeping
- Proactive mindset with willingness to learn, take initiative, and act on feedback
- Good written and verbal communication skills — you will be collaborating with IC&D team members, cross-functional colleagues, and potentially customer-facing documentation
- Ability to manage multiple tasks and meet deadlines in a dynamic, project-driven environment
- Curiosity and genuine passion for the food and beverage industry
- Positive attitude and openness to mentorship — this internship is designed to develop you, and the willingness to be developed is the most important personal attribute you can bring
Advantageous — will strengthen your application significantly:
- Previous internship or academic project experience in food or flavour applications — even a food science laboratory practical, a student project involving sensory analysis, or a food industry vacation job will differentiate you
- Exposure to sensory evaluation or product testing — formal or informal
- Strong analytical thinking and problem-solving skills demonstrated through academic or practical work
What You Will Learn
A year inside IFF’s Johannesburg IC&D laboratory is a genuinely rare and career-defining experience for a food science or chemistry graduate:
- Flavour compounding methodology — understanding how complex flavour formulations are built from individual aromatic compounds, how balance and character are achieved, and how small changes in concentration produce dramatically different sensory outcomes. This knowledge is highly specialised and not taught in any South African university food science programme
- Sensory evaluation science — developing the ability to describe, differentiate, and quantify taste and aroma characteristics using standardised sensory methodologies. Sensory science is a discipline in its own right and professionals with formal sensory evaluation training are in demand across the food industry
- Laboratory operations in a global FMCG environment — understanding how a professional laboratory is run to the quality, safety, and documentation standards required by a NYSE-listed global company. GLP (Good Laboratory Practice), traceability, and compliance with food industry regulations will all be embedded in your daily work
- Applications development — understanding how a flavour formulation is tested, modified, and validated in the actual food or beverage matrix — drink, dairy, snack, or confectionery — for which it is intended. This applied knowledge connects laboratory science to real commercial product development
- Global project exposure — working on both local and global customer projects means you will understand how a multinational food ingredient company manages customer relationships, project timelines, and technical briefs across different markets and cultures
- Professional network within IFF’s global organisation — IFF operates in over 110 countries. The mentors, colleagues, and managers you work with in Johannesburg are connected to a global network of Flavourists, food scientists, and IC&D professionals. The relationships you build during this internship have global career reach
- A foundation for a career in flavour, food science, or FMCG product development — IFF explicitly notes that this internship provides a strong foundation for future career opportunities within IFF itself. Interns who perform well are genuinely considered for permanent roles within the organisation
Possible Interview Questions
Prepare for a combination of technical, motivational, and personality-based questions:
- What do you understand about the role of a flavour house in the food and beverage supply chain — and how does IFF fit into that role globally?
- What draws you specifically to flavour creation and sensory science — rather than food safety, food engineering, or another food science discipline?
- Describe a laboratory practical or food science project from your studies that required you to be especially precise and meticulous — what did you do and what did you learn from it?
- Have you participated in any formal or informal sensory evaluation — product tasting, panel training, or descriptive analysis? What was the experience like and what did it teach you about taste perception?
- What do you know about the difference between natural and artificial flavours — and what are the regulatory and consumer trends shaping how the food industry uses each?
- How do you manage a situation in a laboratory where you make an error in a sample preparation or measurement — what do you do and how do you ensure it does not happen again?
- IFF works with clients across food and beverage categories — from soft drinks to savoury snacks to dairy. Which category interests you most and why?
- What does attention to detail mean to you in a laboratory context — can you give an example of a time when careful attention to detail made a significant difference in an outcome?
- How do you respond to constructive feedback on your work — can you give a specific example of a time you received feedback that was difficult to hear and what you did with it?
- Where do you see your career in the food science or flavour industry five years from now — and how does this internship at IFF contribute to that path?
Tip: IFF is a science-led, innovation-focused global company. In your interview, demonstrate genuine curiosity about flavour science specifically — not just food science in general. Research IFF’s product portfolio, their sustainability commitments, and recent innovation highlights before your interview. Candidates who show they have engaged with what IFF actually does, rather than treating this as a generic food industry application, will stand out immediately in a competitive applicant pool.
Career Advice
- Apply by 17 July 2026 — 19 days remain, but do not wait. IFF is a globally recognised employer and this is a one-year paid internship in a professional innovation laboratory with an explicit pathway to future career opportunities within the company. Applications from strong Food Science and Chemistry graduates will come from across South Africa. Submit your application as soon as your documents are ready.
- IFF is one of the most prestigious names in the global flavour and fragrance industry — treat this accordingly. The flavour and fragrance sector includes a small number of globally dominant companies — IFF, Givaudan, Firmenich, Symrise, and Takasago are the major players. An internship at IFF on your CV signals to every food company, ingredient supplier, and FMCG manufacturer in the world that you have worked inside one of the industry’s leading organisations. This credential is internationally recognised and career-relevant across every geography where food and beverages are manufactured.
- Flavourist is one of the most specialised and rewarding career paths in food science — and IFF is where that career begins. Becoming a fully qualified Flavourist — someone who can create complex, multi-note flavour formulations from first principles — takes years of structured training and experience. Very few South African universities prepare graduates for this path directly. An IFF internship is one of the only ways to access this training environment in South Africa. If flavour creation genuinely excites you, treat this internship as the beginning of a deliberate, long-term career commitment rather than a general work experience placement.
- Sensory evaluation is a skill that requires deliberate development — start now. Begin paying attention to what you taste and smell with genuine analytical curiosity. When you drink a fruit juice, identify the primary flavour notes, the top notes, and the finish. When you eat a flavoured snack, think about what compounds might be creating what you taste. This active sensory engagement, practised consistently, will accelerate your development as a sensory evaluator during the internship and signal genuine passion to IFF’s team from day one.
- Documentation discipline is as important as laboratory skill in this environment. IFF operates to the quality, traceability, and documentation standards of a global regulated industry. Every sample prepared, every measurement taken, every sensory evaluation conducted must be accurately recorded in a way that is traceable, reviewable, and compliant. Developing rigorous documentation habits from the first week of your internship is one of the most professionally important things you can do — it is the difference between a good laboratory intern and one the team trusts completely.
- For Food Science graduates: Your degree has prepared you with the theoretical foundation — food chemistry, food microbiology, sensory science, food processing — that underpins everything IFF’s IC&D team does. The internship will translate that theory into practical, applied knowledge at professional quality standards. Frame your application around the specific modules, practicals, and projects from your degree that are most directly relevant to flavour creation and applications work.
- For Chemistry and Biochemistry graduates: Your strong analytical and molecular foundation — understanding of organic chemistry, reaction mechanisms, analytical techniques, and compound behaviour — is directly applicable to flavour compounding, where the behaviour of aromatic compounds in different food matrices requires chemical understanding. Frame your application around your laboratory competency and your interest in applying chemistry to real consumer products.
- Use the IFF network actively and professionally during your year. IFF’s global organisation connects to flavour and ingredient professionals across North America, Europe, Asia, Latin America, and Africa. The mentors and managers in your Johannesburg team have colleagues, contacts, and former colleagues across this network. Engage professionally with everyone you meet during the internship, maintain your relationships after the year ends, and connect with your IFF colleagues on LinkedIn. The professional network you build during one year at IFF can shape your career across decades.
