| Citric Acid |
Acidulant
Acidulants are used for two primary reasons; to lower the pH of the product to
around or below the isoelectric point of the protein, and to enhance flavour.
In direct acidified products it is important to add the acid in a solution (such
as a 50% citric acid solution), and to add it very s-l-o-w-l-y. |
Citric Acid is
a general-purpose acidulant with a tart flavour profile. |
| Glucono delta
lactone (GDL) |
|
When the pH of the system
needs to be controlled, Lactic
Acid is our first choice, due to its
compatibility with dairy systems and flavours. |
| Lactic Acid |
|
Lactic
Acid is
the acid normally associated with dairy products, providing
a smoother flavour profile
in acidified dairy beverages.
We have found that a balance between these two acids (citric and lactic) works
well
in
most
applications. |
| Maltodextrin |
Bulking
agents |
A Maltodextrin from ADM can
be added as a nutritive bulking agent, with reduced
sweetness in the final product. |
| Polydextrose |
|
Where
a non-standard beverage is required, products such
as polydextrose can be used. Polydextrose is commonly used in Asian
beverages as a source of fibre and digestive aid.
Polydextrose from CJ
is
a bland bulking agent with virtually no sweetness,
and reduced calorific content. |

Hawkins
Watts New Zealand offers a comprehensive range of natural
and artificial colours for use in all beverage
applications.
Our suppliers, Cathay Industries, DD
Williamson and Phytone,
cover the colour spectrum. |
| Mono-di
glycerides |
Emulsifiers
Emulsifiers such as mono-di glycerides can provide
emulsification in recombined products and improve creaminess |
Palsgaard manufactures
a range of specialty emulsifiers from standard mono-di
glycerides that will disperse in cold water
or milk, through to the Palsgaard 5900 range
for recombined milk applications. |
| Flavours |
Flavour |
With developing sophistication
in the acidified milk drink area, consumer tastes
are becoming more demanding.
Symrise flavours are
well placed to offer the complete flavour solution
to all acidified dairy systems. Symrise can provide
fresh, ripe, fruit flavours along
with creamy dairy notes and background
flavours. |
| Microcrystalline
Cellulose (MCC) |
Gums,
hydrocolloids, thickeners, stabilisers
At pH levels below the isoelectric point of casein (approx pH 4.8), proteins
will precipitate and produce a grainy texture when subjected to heat. Particular
hydrocolloids can be added to provide stability in low
pH systems. |
Novagel
MCC from FMC
BioPolymer can also be used in combination
with anionic hydrocolloids to stabilise acidic
milk systems and suspend insoluble material such
as minerals, without increasing perceived beverage
viscosity. |
| Pectin |
|
Herbstreith
and Fox Classic Citrus pectins such
as Classic CM203 prevent proteins
from agglomerating while providing mouthfeel
and flavour release. |
| Propylene Glycol Alginate (PGA) |
|
Protanal
Ester Propylene Glycol Alginate (PGA) from
FMC BioPolymer also
forms soluble complexes with casein in acidic dairy
applications.
 At
Hawkins Watts New Zealand, we have found that each
application is different, so suggest you contact
us for

| Calcium
salts |
Minerals
Many manufacturers choose to add additional minerals
to acidified milk drinks. Typically these include
calcium in a number of formats, but other minerals
can also be added. |
Jost
Chemicals has developed unique new technology
for manufacturing ultra-pure calcium salts with
very low levels of aluminium, lead, manganese, iron
and other vagrant metals. Jost also
has a comprehensive range of purity salts including
ascorbates, carbonates, citrates, fumarates, gluconates,
lactates, malates, nitrates, phosphates, succinates
and sulphates. |

Citrus
Fibre |
Nutraceuticals
The healthy connotations of acidified dairy products
mean that they provide an excellent opportunity for
the inclusion of nutraceuticals. |
Herbafood
Ingredients, 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. |
| Plant
sterols |
|
Plant
sterols have a similar structure to
cholesterol; when absorbed by the body, they
will help block the amount of cholesterol absorbed,
ultimately lowering the blood cholesterol levels.
Cardio-Aid plant sterols from ADM are
based on soy sterols, combined with soy protein and lecithin to produce a water-dispersible
sterol ingredient. |
| Resistant
maltodextrin |
|
Fibresol-2 from Matsutani is
a unique low-viscosity fibre that is highly soluble,
yet contributes very little to taste or texture.
This resistant Maltodextrin will readily disperse
and dissolve in water to form clear transparent
solutions. It is very stable, yet contributes significantly
to the analytical fibre content of products. |
| Spirulina |
|
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. |
| Acesulphame
K |
Sweeteners |
Acesulphame
K is a high Intensity sweetener. |
| Fructose |
|
Cornsweet
Fructose from ADM is
a crystalline sweetener with 1.2 to 1.6 times the sweetness
of sucrose. ADM Cornsweet Fructose can
be used in products where sweetness profile and glucose
content need to be controlled.
ADM Cornsweet Fructose also has
a low glycaemic index and can enhance
the flavour profile in some products such as berry
drinks. |
| Stevia |
|
Stevia from Daepyung is
a natural high-intensity sweetener and sugar substitute
extracted from the Stevia plant with applications
in low-sugar
formulations. It is an excellent sweetener for application in acidified dairy
beverages, because it has good stability at these
pH levels. |
| Sucralose |
|
Sucralose,
a high Intensity sweetener, is also available. |
| Sweetness enhancer |
|
SymLife® Sweet from Symrise is
a flavouring which enhances sweetness, while allowing sucrose levels to be reduced
by as much as 30%. SymLife® Sweet works well in combination
with artificial sweeteners to help round out the aftertaste. |
