Ingredient
and Benefits |
| Acidity
regulators and buffering agents |
| |
In highly
acidic systems such as berry juice concentrates,
the addition of buffering salts, such as Sodium Citrate (usually as a 20% solution),
can improve the acidity profile. |
| Acidulants |
The addition
of a small amount of acid with sweeteners can
enhance flavour perception.
|
Citric
Acid is a natural acidulant that
gives a pleasant acid note.
Tartaric
Acid is
a natural acidulant, but with a slightly
more acidic profile than citric acid.
 Other
less commonly used acidulants are summarised
in the Acidulants section. |
| Antioxidants |
| |
The
most commonly used antioxidant is ascorbic
acid.
Alternatively, sodium
erythorbate (sodium isoascorbate)
can be added to reduce oxidative changes in
the final product. |
| Colours |
| |
HWA
offers a comprehensive range of natural
and artificial colours for use in
all food and beverage applications. Our suppliers, DD
Williamson and Phytone,
cover the colour spectrum.
Phytone,
in particular, excels in producing grape
skin
extracts and other natural colours that are
stable in fruit juices and other beverages. |
| Gums
and hydrocolloids |
| |
Xanthan
Gum is commonly used
to provide viscosity in fruit drinks and nectars due to its
high stability to acid, temperature and enzymes.
Herbstreith
and Fox Instant CJ204 is
an agglomerated pectin which provides extra mouthfeel and
improved flavour release to beverages. |
| Minerals |
Many
manufacturers choose to add additional minerals
to flavoured milks. Typically these include
calcium in a number of formats, but other minerals
can also be added.

HERBAFOOD,
a division of Herbstreith & Fox,
has a range of apple and citrus-derived fibres,
including Herbacel AQ Plus Citrus Fibre. These
fibres have very high water-holding capacity
and have shown to sequester heavy metals, as
well as promoting good intestinal health.
Herbacel
AQ Plus Citrus Fibre gives an appealing
pulpy texture in juices and nectars.
Hawaiian Spirulina,
from Cyanotech is
a micro-algae that is high in all-vegetable protein, rich in
beta carotene, iron, vitamin B-12 and the rare, essential fatty
acid, GLA. It offers a striking profile of vitamins, minerals
and phytonutrients.
Spirulina beta carotene is ten times more concentrated than carrots.
Spirulina also has the broad range of amino acids, along with iron.
Spirulina contains the essential fatty acid Gamma-linolenic acid
(GLA), which is an essential component of breast milk. |
| Preservatives |
| |
Potassium
sorbate will prevent yeast and mould
growth up to a pH of 5-6.
Sodium Benzoate
has a similar effect on yeast and mould growth,
but needs to be used in a product pH below 4,
so is well suited to acidic juice applications.
Care should be taken to ensure
legal requirements are met, and that flavour
profiles are not adversely changed. |
| Sweeteners |
| HWA
offers a range of sweeteners. |
Daepyung
Rebaten (Rebauside A 97%) is a natural low calorie sweetener extracted from the Stevia plant, which has just been approved for use by ANZFA. It is an excellent sweetener for application in fruit juices which are aiming for natural branding.
High intensity sweeteners such as sucralose and acesulphame
K are also available. |
