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.
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.
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.
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.
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.
Food scientists also help support the development of effective
packaging and labelling techniques that help protect food products,
guarantee their quality, and provide consumers with important
information about the product.
They assess the results of different packaging techniques to confirm
that they meet regulatory requirements and codes. They work closely
with manufacturers to develop effective labelling strategies that
provide consumers with accurate and useful information about the
product, such as nutritional content, allergen warnings, and product
origin.

Manufacturing &
Production
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 theresults of sensory tests and leading sensory descriptive analysis
panels. In addition, the completion ofcontract
projects and the provision of sensory information for industry problem
solving is a part of thisrrole.

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.
Ensuring the sensory laboratory is
prepared for the testing
Under direction, conducting sufficient
attribute selection discussion and practice sessionsto ensure the panel is ready to execute the test and

and have
responsibilities to:
Ensure that they do not increase the risk
to the health, safety or welfare of others through any actor omission

items or facilities provided in the interest of health, safetyor welfare of staff
Ensure that they are not affected by
alcohol or any other drug to such an extent that they endangerthemselves or others
Report promptly, any hazards, incidents or
injuries to their Manager/Team Leader
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.
Tools and technologies Education and training/entrance requirements
BSc in a relevant discipline such as Food or Wine Science, Chemistry or
Psychology, preferably havingmajored in Sensory

methodology, in leading sensory panels and in statistical data analysis is
desirable.

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.

Did You Know?
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

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.
— La Fermentation Alcoolique
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. (Source: Wikipedia)
