Malic acid encapsulated sour agent granules

Acidity Regulators

Malic Acid

Product form: Sour agent granule encapsulated in edible hydrogenated oil
Technology: Company original patented technology and equipment
Functions: Acidity regulator, antiseptic, fresh-keeping, anti-caking, anti-sticking
Release: Slow-release, lasting and soft effect

This malic acid granule product is a sour agent granule made from malic acid encapsulated in edible hydrogenated oil, using the company's own patented technology and equipment. The encapsulation is the point: it gives slow release, a lasting and soft sourness, and an anti-sticking effect in the final product, which plain crystalline malic acid cannot do. It is used as an acidity regulator, antiseptic and fresh-keeping agent, and as an anti-caking and anti-sticking agent in food and medicine production.

Quality control

Released against physical description, chemical tests, heavy metals and microbiology with methods stated
Heavy metals to GB5009.12-2010 and microbiology to GB/T4789.15-2003
TDS and MSDS issued with the order, sample COA on request

Where it is used

Acidity regulation in food and medicine production
Antiseptic and fresh-keeping applications
Anti-caking and anti-sticking in powder and granule blends
Slow-release sourness in confectionery and coated products

Who buys it

Confectionery and snack manufacturers
Pharmaceutical formulators
Powder blend and premix producers
Beverage and dessert formulators

Problems it solves

Sourness hitting immediately and fading, instead of building and lasting
Acid granules sticking together or caking in a dry blend
Acid attacking other ingredients on contact in a dry mix, which encapsulation prevents
Fumaric and maleic acid impurities carried in from a poorly controlled malic acid

Packing and options

Granule specification confirmed against the application at enquiry
Packing format confirmed at quotation

How it compares

Plain crystalline malic acid is cheaper and dissolves immediately, which suits a beverage. This encapsulated granule is the one to use in dry blends and coated products where the acid must not react on contact, must not cake, and should release slowly for a lasting soft sourness.

Handling and storage

Use in dry blends where the acid must stay inert until the product is consumed or hydrated
Do not over-heat during processing, the encapsulation is an edible hydrogenated oil coating
Store dry and sealed, keeping granules free flowing

FAQ

Malic Acid questions buyers ask

What makes this different from ordinary malic acid

It is a granule encapsulated in edible hydrogenated oil using patented technology, which gives slow release, lasting soft sourness and an anti-sticking effect that plain crystalline malic acid does not provide.

What assay do you supply

99.0 to 100.5% as C4H6O5, with a reported result of 99.5%.

What are the fumaric and maleic acid limits

Fumaric acid 1.0% max, reported 0.5%, and maleic acid 0.05% max, reported 0.02%.

What functions does it serve

Acidity regulator, antiseptic and fresh-keeping agent, and anti-caking and anti-sticking agent in food and medicine production.

What are the heavy metal limits

Arsenic 2 ppm max and lead 2 ppm max.

Is it suitable for medicine production
