STORAGE AND STABILITY
OF LIQUID PALATANTS
Liquid palatants are moderately viscous, low pH materials
requiring specic storage and handling
considerations. Product-contact surfaces should be constructed
of 316 or 304 stainless steel,berglass or plastic. Carbon, steel
and brass should be avoided. Liquid palatants should be well
mixedprior to use to ensure optimal performance.
Below is additional information on common delivery methods and
stability informationfor AFB International palatants.
GENERAL INFORMATION
BULK
Bulk shipments are typically 5,500 gallons or 20,000 liters and
will arrive at 85-105F/25-30C. These shipmentsmay be ooaded with an
onboard pump or dedicated unloading pump. Bulk storage tanks should
havea capacity of 8,000-10,000 gallons in North America and about
30,000 liters in Europe. They should be equippedwith a high eciency
agitation system that minimizes air incorporation to prevent
foaming and oxidation.Storage tanks should include provisions to
maintain temperatures 85-120F/25-35C (depending on the product)to
control viscosity. AFB is pleased to assist in evaluating designs
of temperature control systems if needed.
Liquid palatant shelf life is typically between six and 12
months. Storage recommendations for individual productscan be found
on the product information sheet. For optimal palatability
performance, storage time for liquidpalatability enhancers should
be minimized.
Periodically (at least annually), bulk tanks should be
completely voided, cleaned, and sanitized. A common
cleaningprocedure is a hot water rinse, followed by foaming with an
alkaline-based solution, and rinsed with a no-rinsefood grade
sanitizer.
An intermediate bulk container, or IBC, holds approximately
2,500 pounds of liquid in North Americaand 1,000 kilograms in
Europe. This container is also sometimes called a tote. In North
America, the IBCis a square corrugated shell surrounding a
polypropylene bag covered with a corrugated top. The bag is
treatedwith an antimicrobial agent to prevent mold growth at the
product bag interface. In Europe, the IBC is a highdensity
polyethylene container with UV protection that is surrounded by a
galvanized steel cage. The IBC maybe stacked two high and should be
stored in an area above 70F/20-25C.
Prior to use, the IBC should be well mixed to ensure optimal
performance. The most common mixing methodis recirculation.

AFB liquid palatants are microbiologically preserved using
potassium sorbate as the primary anti-mycotic, incombination with
an approved acidulant. These products will not support the growth
of common food spoilageorganisms. The integrity of the preservation
system must not be compromised or microbiological growth
ispossible.
Liquid products in IBCs and drums are best stored by minimizing
air contact thereby discouraging growth ofaerobic organisms like
molds. Where used, drum liners should be collapsed and re-tied
after use.
MICROBIOLOGICAL STABILITY
Fat present in liquid products is chemically stabilized using
antioxidants such as mixed tocopherols.Antioxidants are introduced
as early as possible in the manufacturing process to ensure that
fat oxidationis controlled throughout the process.
Excessive agitation and air incorporation into liquid products
may compromise the integrity of theantioxidant system. Dilution or
adulteration of liquid palatant products may destabilize the
preservationsystems being employed. These practices should be
avoided. Contact the AFB Customer Service teamfor assistance should
this occur.
CHEMICAL STABILITY
Liquid palatants are stabilized using different methods to
ensure optimal performance during
product shelf life. Proper product handling is an important part
of ensuring this performance.

A standard drum contains 55 gallons or 200 liters. In North
America, the drum has a polypropylene liner.The liner is tied
closed at the top to prevent air from entering the liner. The
gathered liner is treated withan antimicrobial agent to prevent
mold growth at the product liner interface. If a partially used
drum needsto be stored, be sure that the liner is drawn down,
re-sprayed, and then re-tied to reduce air exposure.
Prior to use, liquid products stored in drums should be mixed
well to ensure homogeneity. In cases wherea drum product is moved
to an intermediate tank prior to use, adequate mixing may be
achieved at this point.
If it becomes necessary to dispose of expired product,
suggestions for disposal can be found on the product ssafety data
sheet or by contacting the AFB Customer Service team.
