Imagine opening a packet of chips intending to eat just a handful, only to find yourself reaching the bottom of the packet minutes later. Or buying a fruit-flavoured drink that looks wholesome, tastes delicious and feels refreshing, without realising how little actual fruit it contains.
Is this simply good food science at work, or has food
engineering become so effective that it sometimes works against the consumer?
Food engineering has brought enormous benefits to society. It has improved food safety, extended shelf life, reduced waste, enhanced consistency and made nutritious products more accessible. The problem is not food engineering itself, but how some of these capabilities are used, not just to improve food, but to encourage people to consume more of it.
Some of the most effective food-engineering techniques are
not inherently harmful. Carefully balancing sugar, salt, fat, flavour and
texture can make products enjoyable and consistent. Creating the perfect
crunch, smooth mouthfeel, appealing aroma or satisfying flavour is a genuine
technical achievement.
However, these same capabilities can be used to make
products exceptionally appealing and easy to consume repeatedly. Highly
palatable combinations of ingredients, convenient packaging, large portions and
aggressive marketing can encourage people to eat beyond their original
intentions.
Think about the snack that seems impossible to put down, the
sugary drink that goes down effortlessly, or the ready-to-eat product designed
for convenience but offering little nutritional value. Each individual design
choice may appear reasonable. Together, they can create an environment in which
consuming more becomes easier than consuming mindfully.
This does not mean that every tasty product is deliberately
addictive or that every manufacturer intends to encourage overconsumption.
Consumer behaviour is complex. Nevertheless, when product development focuses
overwhelmingly on repeat purchases, sensory appeal and consumption frequency,
nutrition and consumer well-being risk becoming secondary considerations.
Food engineering makes food better. Responsible
engineering also considers how much we consume, what we consume and how those
choices affect our health.
Can AI become a force for responsible food engineering?
Artificial intelligence offers an opportunity to bring
greater accountability into food development and manufacturing.
Imagine an AI system that analyses a product's ingredients,
nutritional composition, processing methods, portion sizes and marketing
claims. It could flag excessive levels of added sugar, sodium or saturated fat,
identify potentially misleading health-related claims, and highlight
formulations that may warrant further assessment because of their nutritional
profile and intended consumption patterns.
AI could also help manufacturers reformulate products by
finding ways to reduce sugar, salt and unhealthy fats without sacrificing
affordability, food safety or consumer acceptance. By evaluating thousands of
ingredient combinations, it could accelerate product development and reduce the
trial-and-error process traditionally used by food scientists.
More importantly, AI could help manufacturers look beyond
the question, “How do we make consumers want more?” and ask, “How do
we make a product people enjoy while supporting healthier consumption?”
Such systems must be designed carefully. AI cannot reliably
determine whether a food is intentionally engineered to encourage
overconsumption simply by analysing its ingredients. It would need relevant
nutritional standards, validated research, reliable product data and
appropriate assessment of portion sizes and eating behaviour. Independent
testing and human oversight would remain essential.
The objective is not to dictate what people should eat. It
is to give them better products, clearer information and a fairer opportunity
to make informed choices.
AI is already demonstrating its value in food manufacturing
through quality inspection. One reported industry case involving an Indian
potato chip producer described substantial product losses caused by quality
defects and limitations in manual inspection.
The manufacturer introduced AI-powered visual inspection to
identify undesirable potatoes before processing. According to the published
case study, the system was more than 90% effective at identifying undesirable
potatoes and detected 15% more defects than manual inspection methods.
The challenge was inconsistent defect detection and the
resulting quality losses. The solution was to use AI to inspect products more
consistently and identify defects that human inspection could miss.
Although this example addresses quality control rather than
overconsumption or misleading nutritional formulation, it illustrates an
important principle: AI can make food manufacturing more measurable, consistent
and accountable. Similar capabilities could be combined with nutritional
analysis, recipe monitoring and label verification to support a more
comprehensive approach to responsible food production.
The opportunity now is to extend AI beyond identifying
defective potatoes and towards evaluating whether the finished product meets
nutritional commitments, accurately represents its ingredients and supports
responsible consumption.
Food manufacturers operate in competitive markets, and
taste, convenience, affordability and profitability will always matter. The
goal is not to eliminate commercial success or make food less enjoyable. It is
to ensure that commercial success does not depend on encouraging excessive
consumption at the expense of consumer well-being.
Manufacturers can use AI to improve nutritional quality,
optimise reasonable portion sizes, reduce waste and develop appealing products
that balance enjoyment with health. Regulators can establish clearer standards
for nutritional claims and marketing practices, while independent audits can
help ensure that AI systems deliver what they promise.
Ultimately, AI is a tool, not a moral compass. If it is
programmed only to maximise sales and repeat purchases, it may make existing
problems worse. If it is designed to balance commercial objectives with
nutrition, transparency and consumer welfare, it could become a powerful ally.
We should be able to enjoy our favourite snacks without
needing extraordinary willpower to stop eating them, or a detective's skills to
understand their labels.
The real opportunity is not to stop food engineering, but
to stop rewarding engineering that encourages consumption without considering
its consequences.
Perhaps the most meaningful measure of innovation in the
food industry should no longer be how successfully a product persuades
consumers to eat more, but how successfully it delivers taste, convenience,
nutrition and trust.
That is where AI can make a difference: helping the industry
engineer food that people love, without losing sight of the people eating it.
