Potato Protein for ‘Active Nutrition’
A growing market for natural, ‘free from’ and
sustainable products > Consumers worldwide are seeking more natural food products.
Increasingly, they prefer foods made with unprocessed raw materials, ingredients without
E-numbers which are non-allergenic and derived from sustainable agriculture.
Recent data shows spectacular growth in
new product launches carrying ‘free from’
claims – typically allergens. Examples of ‘free
from’ include gluten-, egg- and dairy/lactosefree.
Retail data indicates consumers are prepared to pay more for ‘natural’ and animal
or environment-friendly products.
Vegan Market Propositions > In Figure 1,
market launches using a vegan claim are
summarised by region worldwide1. Bakery
and cereals is the largest sub segment (all regions, ~15 % of all product launches).
Vegetal protein for nutrition > Published
evi­dence indicates a balanced nutritional
status is the most powerful defence we can
have against disease and sickness. As somebody once said, “We are what we eat.”
In ‘The China Study’, a comprehensive international review of health and nutrition,
evidence was gathered for positive implications when comparing health outcomes
natio­nally, between animal and plant-based
diets2. As such, the study did not prove cer-
tain diets cause disease – but the weight of
evi­dence is so overwhelming the theory is
generally accepted to have some validity. Indeed, ‘Western diseases’ deserve their name
because of their high incidence in affluent developed nations – in contrast to a low incidence in Eastern or developing nations. These
different health outcomes are associated with
the Eastern diet – which is typically low in
animal protein and low-fat.
So what is the theory of the China Study?
That a plant based diet, low in animal protein
and low in fat helps prevent obesity, better
regulates blood cholesterol and reduces the
diseases of affluence: heart disease, a variety
of cancers, obesity and diabetes etc..
Increasing awareness of the relationship between daily food intake and good
health has led to an growing number of
vegans, vege­tarians and flexitarians (who
consume low to no animal protein). Indeed
many vegans and vegetarians do like to supplement their protein intake since plant foods
tend to contain much lower amounts of total protein than animal derived foods. Moreover, vegetarians or vegans may only supplement with plant-derived sources of protein.
Slow protein digestion > Native intact protein
is a highly recommended source of dietary
amino acids, beneficial for protein synthesis in the body. For example, leucine in protein is used more efficiently for protein synthesis than the free amino acid3. Leucine, is
perhaps the most important Essential Amino
Acid for its role in stimulating muscle growth
and maintenance (anabolism): it is particularly abundant in PRO GOTM.
Clinical study data on PRO GO™ digestion
kinetics shows a steady and prolonged supply of amino acids together with a low insulin response and a stable blood glucose level:
a slow protein that maintains the balance of

nutritional homeostasis. This ‘steady state’
effect suggests novel nutritional concepts may
be developed targeting consumer solutions in
the endurance sport and metabolic manage­
ment areas: since a low insulin peak and
stable blood glucose, combined with good
digestibility offers a more balanced proteincarbohydrate solution4.
For PRO GO™, a good response is also reported for gastro-intestinal comfort. Such a
protein might be beneficial after – but also before, and during exercise – since unlike dairy
protein it does not clot in the presence of acid.
Timing of protein intake > Protein intake
serves two nutritional goals: firstly as a fuel,
and secondly to stimulate cellular response.
The literature reveals the timing of protein intake is very important. Protein is an essential part of the diet, not only at meal times
but also in between, especially for improving
exer­cise (sport) and overall performance. Protein intake supports the repair of damaged
muscle tissue, muscle hypertrophy, increasing
lean body mass and physiological wellbeing3.
Active nutrition > The use of protein immediately after exercise for recovery is well established in sports nutrition. However, the
literature reveals intake of protein before and
during exercise may be beneficial as well3.
Consumption before exercise might be bene­
ficial since the adverse effects of heavy exer­
cise may be counteracted immediately after
undergoing serious effort3.
During resistance exercise, protein intake
increases the synthesis rates of whole body
and muscle protein. In endurance exercise,
protein intake benefits muscle synthesis. Increased exercise intensity and duration results in a raised requirement for fuel, which
could be fulfilled by a higher protein intake
of up to 50 %. Furthermore, the net protein balance at rest, during exercise and postexercise recovery, increases when combining
ingestion of carbohydrate and protein3.

Besides protein intake during the day, ingestion has also been studied before and through
sleep. Protein is well digested and absorbed
prior to sleep, and throughout the night, because the gut functions well during sleep –
it never sleeps!3 In young healthy men, after
a period of resistance exercise, protein taken
before sleep improves post-exercise recovery
overnight5. These trials were performed with
a ‘slow’ protein.
The balanced digestion kinetics of PRO
GO™ combined with good gastro-intestinal
comfort suggests it could be beneficial before
and through exercise, as well as before sleep.
Active applications > PRO GO™ has a
broad application range: from familiar bars
and powders blends, to high protein snacks;
and being readily soluble it performs well in
Ready to Drink (RTD) beverages, non-dairy
milks, and protein gels. Three target applications are currently being developed where
PRO GO’s™ nutritional benefits are combined with its clean taste and unique functionality: high protein crispy snack textures
and RTD clear protein waters (2 %) and clear
gels (5 %).
The unique functionalities displayed in
these applications are:
1.Creation of novel (crispy) snack textures
2.High solubility with perfect clarity + gelation on heating
High protein crispy snacks depend on PRO GOTM for their
unique aerated texture.

High protein – Healthy snacks > The most
effective way to stay slim is to reduce overall
calorie intake, in combination with exercise.
Healthy protein snacks help to curb hunger and reduce overall calorie intake when
snacking: when it’s better to use extra protein than fat!
Examples of high protein snacks are snack
balls, breakfast crumbs, and ‘crispies’ for
high protein bars. The biggest challenge in
baked snacks is to combine nutrition without
losing dough cohesion, which PRO GOTM
can provide. Varying the water level and
bake settings alters the final texture. After
baking, even at very low water levels, PRO
GOTM creates sufficient cohesion to prevent
loss of product shape, yet retains air cells to
give foam stability.

taste options, and are preferred by those who
wish to avoid choking on crumbs when exercising – since they are easily swallowed without the distraction of chewing.
PRO GO™ can deliver a variety of clear
gel textures depending on the protein concentration, pH and salt level. At low pH (< 3.5)
and protein levels of 3–6 % the viscosity increases on heating. After cooling this may result in a clear gel with a smooth and creamy
texture which is ideal for sports athletes who
prefer a one shot intake.
When salt is added to the solution a firm
gel develops on heating. This ionic gel has a
short brittle texture – but when stirred during
cooling, the resulting texture is very easily
swallowed – being smooth and flowable.
Fig. 2: The viscosity profile of PRO GOTM gel
In this instance PRO GO™ is used both as a
nutritional source and sole texturiser – it is
possible to create a gel without the use of any
other additional thickeners, gelling agents
or extremely high sugar levels. Natu­rally,
all kinds of fruit juice bases and flavours fit
very well here e. g. cranberry, blueberry and
green tea.
Conclusion > PRO GO™ is a novel, and
highly nutritious vegetal protein with unique
functionality. It can be used to create balanced
nutritional consumer proposition – which
supports a modern sustainable life style.
