Almond Processing Industry Report
I. Almonds Production in Australia
Australia is the world’s second largest almond producer, with 6% of world almond
production behind the United States, which produced around 85% of the global crop.
Due to the growing global demand and the drought in California, the main U.S.
almond producing region, significant new investment has occurred in Australia, while
the fall of the Australian dollar increases the exports returns.
In 2014/15, almond production in Australia reached 75,000 MT, increasing from
16,000 MT a decade ago. The total area planted to almonds has increased to almost
29,000 hectares, with 80 percent planted over the past decade. With 4% of plantings
not yet bearing and one third of bearing trees not fully mature, the production of
almonds will continue to increase.
Almonds were first planted in South Australia on Kangaroo Island in 1836. Now
almonds are primarily grown within the Murray Valley in South Australia, Victoria
and New South Wales, with the major producing regions being the Adelaide and
Riverland regions of South Australia, the Sunraysia region of Victoria, and the
Riverina region of New South Wales.
A wide range of almond varieties is grown in Australia. Nonpareil, which was
imported from California in 1982, is the main commercial variety, accounting for over
50% of plantings, followed by Carmel, Price, Peerless, Neplus and Fritz. The
Nonpareil has the classic shape and flavor favored by all over the world. The Carmel
has a more intense almond flavor. The Price almonds taste sweet and buttery, which is
great to be eaten as a snack and as an ingredient.
II. Australian Almond Processing Industry
The almond industry is one of Australia's fastest growing horticultural industry,
servicing an expanding domestic market and export markets. By 2015 the area under
almond production is expected to be about 32,000 ha and estimated total kernel
production, 85,000 t. Almonds have become an attractive crop for investors because
the industry is highly mechanized, suited to large-scale orchards and has proven to be
profitable and stable.The almond production cycle in Australia includes three phases:
almond growing (farm), almond hulling and shelling, and shelled almond
processing(treatment and packaging).
● Almonds growing stage
Almond kernels develop in a shell
surrounded by a soft outer hull and
the nuts dry in the shell before
harvested. The trees take three
years to bear a crop and seven to
averaging 3.2 MT per hectare. Almond trees are dormant from May to July, and starts
to bloom in the spring from late July to early August. During September and October,
the petals fall and leaves begin to form. The fruit starts to form over spring and the
hulls surrounding the shell mature and harden, which start to split over summer until
the shell is visible and begins to dry out. At last the nut separates from its stem and the
hull opens completely. Harvesting of almonds usually occurs during the months of
February to April.
The Australian almond industry is highly mechanized and influenced heavily by
Californian style machinery for both on farm operations and almonds processing. The
almonds are mechanically shaken from the tree and left to dry on the orchard ground.
After 7-14 days when the kernel moisture content is lower than 6%, the almonds are
collected and placed in large stockpiles for storage. Aerated storage and dehydration
after collecting can help prevent mould growth and maintain the quality of almonds.
● Almonds hulling and shelling processing stage
The harvested almonds are transported to a hulling and shelling facility. First a
cleaning process is adopted to remove foreign material from the almonds. Then
almonds including hull, shell and kernel are processed there to remove the hull by
almond dehulling machine to get in-shell almonds from hulls and in-shell almonds are
further shelled by almond cracking & shelling machine to produce kernel.
● Shelled almonds processing stage
After hulling and shelling, the almonds are transported to the processing facilities,
where they undergo a range of activities such as peeling, sorting, grading, blanching,
milling, chipping, roasting, and packaging.
Australian almond sizes are represented as number of almonds per ounce, which is
consistent with international standards. The grades are: Fancy, Extra Supreme,
Supreme, and Manufacturing.
Almonds can be slivered by almond kernel slivering machine into strip shape, sliced
by almond slicing machine into almond slices, diced by almond kernels chopping
machine into small granules which are widely used in bakery food processing, such as
the biscuit, candy, chocolate, cookie, etc., split, left whole or ground (meal/flour).
Almond milk is now the most popular plant based milk, with sales higher than
III. Market Demand of Australian Almonds
● Domestic consumption of almond in Australia
Almond is a good source of protein, vitamin E, dietary fiber and monounsaturated fat.
A diet including a handful of almonds 3-4 times a week may help maintain heart
health, help with weight loss, prevent diabetes, fight arthritis and cancer.
Almond is consumed in multiple ways in Australia. The kernels are consumed raw or
roasted as snacks. Almond and its paste and milk are used as ingredients in breakfast
cereals, snack bars and other manufactured goods. The almonds are also widely used
in home cooking and restaurant dishes. More and more people like to use gluten free
almond meal to substitute flour in baking. From March 2014 to March 2015, 192 new
products using almonds were stocked by supermarkets, compared with the second
popular tree nut cashews used in 72 products.
In the past five years, Australian almonds consumption has increased by more than
50%, while global demand has doubled over the past decade. With the rising of living
standards in developing countries, the expansion of new market, and increased public
awareness of almonds’ health benefits, the consumption of almonds continues to grow.
● Exportation of Australian almond
Over the past five years, export sales have increased 246% and domestic sales have
increased 55%. In 2014/15, almonds were the most valuable horticultural exports in
Australia, with annual export sales of $422 million. 50,000 tonnes were exported and
20,000 tonnes sold domestically. In 2015-16, export sales will reach $600 million,
with $800m leaving the orchards. The orchard will continue to expand across the
The quality of Australian almonds is highly regarded in world markets. Australia
exports almonds to 50 countries, with India being the largest market. The Indian
market prefers in-shell almonds which are then hand cracked. Australian product has
an excellent crack-out ratio (kernel to in-shell weight), while some Indian buyers like
the shape of Australian kernel. Spain and the United States were also large markets in
2014/2015, and sales to the United Arab Emirates increased significantly.
IV. How to Make Use of Almond Hulls and Shells in Australia
While almond kernel production has received so much attention in Australia, the hulls
and shells, which account for 70% of the harvested weight, so far have little economic
In Australia, the primary use for almond hull and shell is for cattle feed. The hull and
shell is sold between $0 to $35/tonne to freight companies who transport and sell the
product to dairies and feedlots, the final price being much higher than that received by
the almond industry.
The scope to increase the quantity sold or value obtained is limited. Customers are
often located too far away while the hull and shell has a low density, so the freight is
expensive. Second, the almond hull and shell makes up only 5-10% of the animals
diet. Demand can be especially low when other preferred feed sources are cost
Almond hulling and shelling costs in Australia are estimated at approximately
$0.30/kg, being one of the most expensive operations in the almond industry.
However, the properties of hull and shell decide that there are various other
applications of the almond hull and shell, such as being used as bioenergy, biochar,
compost, and so on.
