The Role of Food Scientists in the Food Industry

Recipe & Ingredient Development

Food scientists aren’t chefs: they’re scientists with a deep understanding of the chemical and physical properties of food. They use this knowledge not only to design recipes but also to understand the manufacturing process from when the product is an idea to when it hits the shelves. They help food brands develop and tweak recipes and ingredients that are not only tasty but also safe and healthy to consume.

Food scientists can also create new ingredients or improve existing ones by using their expertise in food chemistry and processing. They can also identify the best ways to source and combine ingredients to maximize flavour, texture, and nutritional value. This can impact the cost of production, and ultimately the product’s purchase price.
Recipe Book
Scaling Up Food Production

Food scientists use their expertise to develop processes that increase efficiency and quality while maintaining food safety. They analyze the composition of raw materials, develop new formulations and recipes, and design production processes that can be replicated on a larger scale.

Food scientists also conduct sensory evaluations to ensure that mass production of a product still meets desired flavour, texture, and aroma characteristics. Imagine biting into your favourite childhood confectionery only to find the flavour isn’t right. Food scientists work to ensure that each piece retains its signature flavour and is safe to consume–no matter how large the scale of production is.

Through conducting nutritional assessments, food scientists can analyse the composition of raw materials, including their macronutrient and micronutrient content, and evaluate how different processing techniques may affect their nutritional value. They provide accurate and reliable nutritional information to food and beverage companies, enabling them to make informed choices about their products, and influencing the creation of product descriptions.
Scale Up
Food Safety & Quality

Food scientists can identify potential hazards, develop appropriate control measures, and monitor food processing and storage environments to prevent contamination. Through the use of different testing methods, they can detect harmful pathogens, allergens, and chemical contaminants that may be present in food.

They also work to optimize food processing techniques to minimize the risk of quality issues, such as spoilage or loss of flavour and texture.
Contaminated Food
Food Preservation & Shelf Life

Food scientists also assist in preserving the quality and extending the shelf life of food products, whether they are organic or conventional. They help manufacturers and food and beverage companies identify the best preservation techniques, such as canning, freezing, or drying, that can help prevent microbial growth and deterioration of food quality.

They also evaluate the impact of different processing techniques on the nutritional content of the food and its flavour and texture. They monitor storage conditions and develop packaging materials that can help preserve the freshness and quality of food products over extended periods. The development of effective preservation techniques can help reduce food waste and increase food security for consumers.
Shelf Life
New Production Technologies

Because food scientists have a detailed understanding of the food manufacturing processes, they can help develop new production technologies that can increase efficiency and quality in the food industry. They evaluate the results of new and old technologies and assess their impact on food product characteristics and safety.

They then work closely with manufacturers to test and optimize the new technologies to ensure that they deliver the desired results. Food scientists can help manufacturers stay competitive, reduce costs, and improve the quality of food products for consumers.

Michael Nestrud, a sensory scientist, and Kathryn Kaufman, senior principal scientist, prepared juices for testing at Ocean Spray headquarters in Lakeville.

There’s so much more to taste than the yum factor. Sensory scientist Michael Nestrud of Ocean Spray said enjoying food is a multisensory experience that includes scent, colour, temperature, and clarity.

Nestrud likes to call himself a culinary psychologist because he’s always seeking to explain why consumers prefer certain flavours over another — particularly when it comes to Ocean Spray’s cranberry and juice drinks. Nestrud spoke about how the Lakeville-based producer uses taste tests for new flavour development.

Sensory analysts assess the various characteristics of food in order to evaluate both new products which are being tested for the market, and established products as part of product development and quality control.

Sensory analysts will work closely with products to assess their shelf-life. Changes which may occur during storage affect the quality of the product over time and eventually determine the particular shelf-life. Negative changes in appearance, odour, and taste can occur if products are stored for too long and sensory analysts will work to assess when exactly these changes occur. This will help manufacturers ensure that their products retain their quality throughout the required shelf-life.

The food industry depends heavily on sensory analysts, whether they are developing a new product, trying to decide whether a taint from chemical contamination has affected a product, establishing how long a shelf life is appropriate or maintaining quality control. It is the job of sensory analysts to make sure, using their various senses, that the products are tested scientifically and with as much objectivity as is possible.

The Sensory Analyst carries out sensory tests to support research projects and programs that
add value eg. to the Australian wine industry. The role involves designing, conducting, and interpreting the results of sensory tests and leading sensory descriptive analysis panels. In addition, the completion of contract projects and the provision of sensory information for industry problem solving is a part of this rrole.

Did You Know?

Sensory tests which are used to assess products include triangle tests, paired comparison tests, and ranking tests.

Triangle tests provide the sensory analyst with three coded samples, two of which are the same and one of which is different. The sensory analyst will need to identify which sample is different.

As the name suggests, paired comparison tests present sensory analysts with a pair of coded samples and this is one of the most popular methods of presenting samples for comparative judgement.

Ranking tests see sensory analysts working with at least three coded samples. They will usually be looking for a particular characteristic and the testers will need to rank the samples with regards to intensity of that particular attribute. This test is often used to assess which products are the best and therefore the most suitable for further testing by consumers.

For example, if a manufacturer of a curry sauce is launching a new Vindaloo sauce, three or four samples may be produced which have different levels of a particular spice in them. The sensory analysts will need to assess which sample contains the optimum amount of spice. The manufacturer of the curry sauce will then use these results to decide how much spice to add to the final product.

Other tasks carried out by sensory analysts on a regular basis include difference tests, product profiling, and rating tests.

Working conditions

Reports to: Senior Sensory Scientist.

The round the table discussions which sensory analysts participate in are normally carried out in a room set aside for the purpose. The actual assessment of the product is carried out in individual booths in a laboratory set-up. As the products often have to be kept at a consistently cool temperature, the booths can often be somewhat chilly. Theoretically, there should be no danger associated with the job, although sensory analysts have been known to experience the occasional unpleasant side-effect from some of the products.

Sensory analysts do not need to wear a specific uniform or protective clothing but they will need to avoid perfumes and perfumed products, since this confuses the nose and interferes with the sensory process. Eating a curry the night before can leave the taste of garlic in the mouth, which would also have an adverse effect on the palate’s efficiency, so this should be avoided.

Sensory analysts are unlikely to work more than a few hours per day because the palate tires easily. Between assessments, water and cream crackers are used to cleanse the palate. This job is fairly sociable because there are normally reasonable breaks between sessions to allow the palate to recover. Evening and weekend work would be highly unusual.

Professionals who study fermentation. Fermentation science is based on the natural chemical process by which sugar is broken down into carbon dioxide and alcohol utilizing a single cell microorganism called yeast. However, most people would probably be more familiar with this term as it relates to the creation of beverages such as beer, wine and spirits.

Zymology, also known as zymurgy, is an applied science that studies the biochemical process of fermentation and its practical uses. Common topics include the selection of fermenting yeast and bacteria species and their use in brewing, wine making, fermenting milk, and the making of other fermented foods.

"Strictly speaking, the term "fermentation" relates to anaerobic energy metabolism only. The word is derived from the Latin "fermentare" (to cause to rise), reflecting the foaming that occurs during the preparation of wine and beer."

Fermentation science, or zymology, is the study of zymurgy, the applied science of fermentation which deals with the biochemical processes in fermentation, yeast & bacteria selection and physiology, and of course, the application of this science by way of fermented foods, dairies, and beverages (ie: distilling, wine making, brewing, and the fermenting of various foods).

Zymology is the science that investigates fermentation, a natural process where microorganisms like yeasts and bacteria convert sugars into other products, such as alcohol and carbon dioxide, or acids.

Fermentation dates back to 10,000 BCE when early humans used to preserve milk from cattle, sheep, goats, and camels.
  
The scientific investigation began in the 16th century. People used fermentation to make products such as wine, cheese, and beer long before the process was correctly understood.

One of the oldest forms of food processing known today, the fermentation process can occur in both plant and animal based products, so many of mankind's favourite food and beverages, such as beer, wine, bread, sausages, and various sauces & marinades, exist due to fermentation.

Vegemite on Toast

Vegemite is a thick, dark brown Australian food spread made from leftover brewers' yeast extract with various vegetable and spice additives. It was developed by Dr Cyril Callister in Melbourne, Victoria, for the Fred Walker Company in 1922 and was first sold in stores on 25 October 1923.

A spread for sandwiches, toast, crumpets and cracker biscuits as well as a filling for pastries. Vegemite has a strong flavour. It is salty, slightly bitter, malty and has an umami flavour similar to beef bouillon (because it is rich in glutamates). It is low FODMAP, vegan, kosher and halal. It is known for being high in B vitamins.

Following the death of Fred Walker in 1935, the Vegemite brand came under the ownership of the American company Kraft Foods. However, in 2017 the brand returned to Australian ownership when the Bega Group purchased it.

Did You Know?

French chemist Louis Pasteur was the first 'zymologist' when in 1857 he connected yeast to fermentation. Pasteur originally defined fermentation as "respiration without air".

Pasteur performed careful research and concluded:

Je pense que la fermentation alcoolique ne se produit jamais sans une organization simultanée, une développement, une multiplication de cellules … . Si l'on me demandai en quoi consiste la réaction chimique par laquelle le sucre et décomposé … je l'ignore complètement.

I am of the opinion that alcoholic fermentation never occurs without simultaneous organization, development and multiplication of cells … . If asked, in what consists the chemical act whereby the sugar is decomposed … I am completely ignorant of it.

The German Eduard Buchner, winner of the 1907 Nobel Prize in chemistry, later determined that fermentation was actually caused by a yeast secretion, which he termed 'zymase'.

The research efforts undertaken by the Danish Carlsberg scientists greatly accelerated understanding of yeast and brewing. The Carlsberg scientists are generally acknowledged[by whom?] as having jump-started the entire field of molecular biology.
