Cacao, the main component used in the creation of chocolate and other cacao-b...AdelinePdelaCruz
Cacao, the main component used in the creation of chocolate and other cacao-based products is cacao beans, which are produced by the cacao tree in pods. The Maya and Aztecs, two of the earliest Mesoamerican civilizations, valued cacao as a sacred plant and used it in religious rituals, social gatherings, and medical treatments. It has a long and rich cultural history.
A Review on Recent Advances of Packaging in Food IndustryPriyankaKilaniya
Effective food packaging provides number of purposes. It functions as a container to hold and transport the food product, as well as a barrier to protect the food from outside contamination such as water, light, odours, bacteria, dust, and mechanical damage by maintaining the food quality. The package may also include barriers to keep the product's moisture content or gas composition consistent. Furthermore, convenience is vital role in packaging, and the desire for quick opening, dispensing, and resealing packages that maintain product quality until fully consumed is increasing. To facilitate trading, encourage sales, and inform on content and nutritional attributes, the packaging must be communicative. For storage of food there is huge scope for modified atmosphere packaging, intelligent packaging, active packaging, and controlled atmosphere packaging. Active packaging has a variety of uses, including carbon dioxide absorbers and emitters, oxygen scavengers, antimicrobials, and moisture control agents. Smart packaging is another term for intelligent packaging. Edible packaging, self-cooling and self-heating packaging, micro packaging, and water-soluble packaging are some of the advancements in package material.

SENSES
• The way we perceive food, from a
sensory point of view, is determined by
the five human senses: sight, smell,
taste, touch and hearing. The success
of food greatly depends on the extent
to which their sensory quality appeals
to the target population.
• Other benefits such as the health
aspects may enhance the perceived
value of the food but can be largely
useless if the sensory qualities are
unattractive.
• …”You can tell me its good for me but
that’s no good if it looks, tastes & feels
like cardboard!”

Food Variables…
“Our senses are designed to work together, so when they are combined, the brain
pays more attention and encodes the memory more robustly.” Medina (2014)
All variables & senses intertwine when assessing food (multi-modalities). Sensory
analysis (or sensory evaluation) is a scientific discipline that applies principles of
experimental design and statistical analysis to the use of human senses (sight, smell,
taste, touch and hearing) for the purposes of evaluating consumer foods. They are
generally ‘packaged’ and assessed as the following:

6. Innovating food for seniors
Discrimination tests can be used
to determine if dishes/ products are
different from each other
• If a given characteristic
(crunchiness, softness, melt point
etc.) is different among samples, or
• If one product has more of a
selected characteristic than
another.
1. Analytical Methods:
Descriptive methods are used
to provide more-comprehensive
profiles of a product by asking
panellists to identify:
• different characteristics within
the product and
• quantify characteristics.
Better results are forthcoming
from trained taste panelists.
Analytical methods of sensory evaluation are
most commonly discrimination and/or
descriptive methods.
7. Innovating food for seniors
2. Affective Methods:
Bringing together a panel of your target
consumer to answer questions such as:
• Which product do you prefer?
• Which product do you like?
• How well do you like this product?
• How often would you buy/use this product?
Affective methods require a much larger panel
size than do analytical methods, to give
greater confidence in the interpretation of the
results.

Food Variables: Appearance should also be Considered…
Digestion starts in the eyes. Food appearance helps
prepare the mouth for the incoming food (the mouth-
watering effect). The technical description…..
Food appearance determined mostly by surface colour is
the first sensation that the consumer perceives and uses
as a tool to either accept or reject food (Leon et al., 2006)
Appearance tests consider the visual perception of food
which includes colour, size, shape, transparency, dullness
and gloss.
Appearance and colour are easily explained through fruit.
As a fruit ripens, the colour becomes enriched or
alternatively as a food spoils or stales, a loss of colour
occurs.

Visual and Olfactory…
WHICH ONE WOULD YOU CHOOSE?
Visual perception or olfactory signals
(smell) are usually the first senses to
provide information or a perception on
the quality of food.
10. Innovating food for seniors
Flavour usually consists of 3 Components:
This contributes to
the pleasure of
eating: e.g. the
aroma of freshly
baked bread
SCENT
This is the physical
sensation a food or
drink creates in the
mouth, sometimes it
is interlinked with
texture
MOUTHFEEL
This plays a vital role in
recognising, accepting
and appreciating food:
sweet, salt, sour,
bitter, umami
TASTE

food
for
seniors
• To provide a detailed specification of a
single product (a retailer might ask for).
A basic description often contains:
aroma/taste; appearance, flavour;
mouthfeel/trigeminal; aftertaste
• To compare products (e.g. quality
attribute sheets- normally for a large
company)
• To aid in determining the Shelf-life
• For NPD: target matching (with the
market need/preferences)
• To resolve or as part of trouble shooting
customer complaints

How Our Senses Interact
Leatherhead Food Research published an
excellent research paper to help us
understand how the senses operate
together.
Over 7 pages, it shares fascinating
investigations such as the physical
(tactile/taste) interactions. It is a powerful
tool for food product developers and
marketing professionals.

Discrimination Tests…
“What is the nature of the difference between samples?”
• Use when you need to identify the nature of the detectable
differences of samples (e.g. very spicy or strong flavours in the
products) a discrimination test can be used.
Examples of discrimination tests:
• Triangle test (e.g which sample is the most different?)
• Paired comparison test (e.g which sample is sweeter?),
• Other tests such as Duo-trio test (e.g. chose the sample that
matches the reference)
17. Innovating food for seniors
Quantitative measuring of consumers’ opinions…
• Preference test
• Acceptance test
• Using consumers judgments to
foods (e.g. liking, wanting,
purchase intent)

Sensory Testing for Older Consumers – Recommendations
• Recruiting older consumers/tasters requires a thorough selection process : (e.g. evaluation of
the cognitive status, evaluation of sensory capacities, evaluation of oral dental health etc).
• Tests should be simplified, with less workload during the tasting session (e.g. as the older
population easily gets tired, more time for instruction, for the training phase, fewer products to
taste etc,).
Practical recommendations
• Give ‘easy-to-read’ instructions and testing questionnaires
• Give instruction both orally and in writing (then individual check ensuring understood well)
• Strict and appropriately long rinsing protocol must be respected before each tasting
• Investigator or trainer should be being nice to seniors, but neutral, avoiding bias
19. Innovating
food
for

• Using sensory analysis during your NPD journey
will give more information on the product and
knowledge of consumer preferences
• Sensory techniques can apply to the entire
process from idea generation, and feasibility
testing, to development and production, and
launch.
• It’s a good idea to firstly, find out the sensory
attributes at kitchen scale/development stage.
You can use internal or external panels for this.
• Something else to consider is the Product shelf
life – some products’ end shelf life is dependent
on their sensory change rather than the
microbiological aspect.

20. Innovating

As seen in the last slide Sensory analysis
is linked with the entire NPD process but
it is particularly relevant when at the QA
stage…you need to determine:
• Does the product meet the targeted
sensory specification?
• How does the manufacturing process
affect the sensory quality of
ingredients or the end-product?
• Do any quality changes occur over
time (shelf life, any variation in
sensory quality from batch to batch?
If so, how much variation is acceptable?

Up to this point in our course, we
have learned that seniors’ food
choices are made as a result of a
diverse set of negotiations between
their needs, ideals, values, and
contextual influences on those ideals
and values.
Designing novel food products and
their packaging, for pleasurable
outcomes across these negotiations
provides an opportunity to improve
the overall acceptance of newly
designed foods among senior
consumers.
