DAIRY BEVERAGES
Acidified
dairy beverages
Although still in their infancy in New Zealand and Australia, acidified
dairy beverages are popular in Asia and South Africa. Products vary from
thick indulgent yoghurt drinks with high dairy content, through to light,
refreshing juice and dairy products.
| Ingredient Functionality |
Ingredient and Benefits |
| Acidulants. |
| 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. |
ADM Citric
Acid is a general-purpose acidulant
with a tart flavour profile.
ADM 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 works well in most applications. |
| Bulking
agents |
Used 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.

on Bulking Agents |
An ADM Maltodextrin can
be added as a nutritive bulking agent, with reduced
sweetness in the final product.
CJ Corp Polydextrose is
a bland bulking agent with virtually no sweetness,
and reduced calorific content. |
| Colours |
| |
HWL offers a comprehensive
range of natural and artificial colours for use
in all food and beverage applications.
Our suppliers, Cathay Industries, DD
Williamson and Phytone,
cover the colour spectrum. |
| Emulsifiers |
| Emulsifiers such
as mono-di glycerides can provide emulsification
in recombined products and improve creaminess. |
Palsgaard
A/S 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 |
With developing sophistication
in the flavoured milk 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. |
| Gums
and hydrocolloids |
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. Special hydrocolloids
can be added to provide stability.

information in our Gum Selector |
HWL recommends
these hydrocolloids to provide stability in
low pH systems:
FMC
BioPolymer Protanal Ester Propylene Glycol
Alginate (PGA) also forms soluble complexes
with casein in acidic dairy applications.
Herbstreith
and Fox Classic Citrus
pectins such as Classic CM203 prevents proteins
from agglomerating while providing mouthfeel and flavour
release.
 Yoghurt

FMC BioPolymer Novagel
MCC 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.

| 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. |
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.
Kirsch
Pharma supplies HWL with a comprehensive
range of high quality inorganic mineral salts for
use in beverage fortification. |
| Nutraceuticals |
| The healthy connotations
of acidified dairy products mean that they provide
an excellent opportunity for the inclusion of
nutraceuticals. |
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.
ADM Cardio-Aid
plant sterols are based on soy
sterols, combined with soy protein and
lecithin to produce a water-dispersible
sterol ingredient.
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.
Fibresol-2, manufactured
by ADM for Matsutani
Japan, 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.
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. |
| Sweeteners |
| HWL offers a range
of sweeteners including ADM Cornsweet Fructose,
which can be used in products where sweetness
profile and glucose content need to controlled. |
ADM Cornsweet
Fructose is a crystalline sweetener
with 1.2 to 1.6 times the sweetness of sucrose.
ADM Cornsweet Fructose also has a low glycaemic
index and can enhance the flavour profile
in some products such as berry drinks.
High Intensity sweeteners
such as sucralose and acesulphame K are also
available. |
