Agritechnology: industrial microbiology, fermentation & food science
Bridging the
Marketplace
Agritechnology's approach to
cherry waste can benefit other primary producers by realizing value in their
waste stream, particularly in the production of grapes, apples, olives and other
stone fruits.
Cherry juice is available in 1000 litre bags.
The
cherry extract powder is available in sealed 15kg
bags.
As well as deriving food
from cherry waste in the form of juice, Agritechnology used its food science
capabilities to extract a valuable functional food and nutraceutical ingredient.
This took the form of a concentrated extract of sweet cherry in powder form. Its
functional benefit is in
its red colour and intense cherry flavour; its
nutraceutical benefit is in its high anthocyanin content. The ingredient was
produced as a
powder as this
broadens its potential range of applications for customers. The nutraceutical
content of the product has been analysed using the HPLC method and the product
has a guaranteed anthocyanin content.
PRODUCT SPECIFICATION
Creating a New Product from
Waste
Using their food science capabilities,
a
controlled enzymatic process was developed to create a
shelf stable juice or homogenate. This process created a product with a high
yield, well defined organoleptic texture and flavour properties, and most
importantly, the end product retained a high level of anthocyanins - an
important antioxidant.
With Agritechnology's Orange laboratory based
in the heart of NSW's fruit growing region, stone fruit was an obvious area to
investigate in the production of functional foods and
nutraceuticals.
Agritechnology knew that cherries have well
substantiated levels of anthocyanins with known nutraceutical properties: anti
inflammatory, gout, obesity, sports recovery / muscle damage, amongst others. In
addition, cherries are well known as a low GI food, making cherry derived
products highly applicable to the diabetic market. Agritechnology was also aware that local primary producers had a
waste stream of second grade cherries which
represented anything from 20% to
50% of their annual crop.
Agritechnology's fruit nutraceutical technology
has been designed to realise additional value from this waste stream for the
primary producer in two ways: converting the waste into food; and extracting
valuable nutraceutical compounds from the waste.
