Abstract
The invention provides a particulate composition comprising at least 1 wt. % of malate particles, said malate particles having a diameter of 50 to 1000 μm and comprising at least 70 wt. % of co-crystal of malic acid and alkali metal hydrogen malate. Co-crystals of malic acid and alkali metal hydrogen malate can be produced in the form of powders that exhibit very low hygroscopicity and that are capable of imparting a sour flavour that is very similar to that of malic acid. The invention also relates to the use of the aforementioned malate particles as a food ingredient.
Claims16
A particulate composition, comprising at least 1 wt. % of malate particles having a diameter of 50 to 1000 μm and comprising at least 70 wt. % of co-crystal of malic acid and alkali metal hydrogen malate.
A process of preparing malate particles comprising co-crystal of malic acid and alkali metal hydrogen malate, the process comprising:
- (a) providing seed crystal particles containing at least 80 wt. % of crystalline material selected from crystalline organic acid, crystalline salt of organic acid and combinations thereof;
- (b) providing an aqueous malate solution, comprising sodium and malate in a molar ratio of 4:10 to 6:10 or comprising potassium and malate in a molar ratio of 5.5:10 to 7.5:10;
- (c) spraying the aqueous malate solution onto the seed crystal particles to produce coated particles;
- (d) removing water from the coated particles.
A process of preparing malate particles comprising co-crystal of malic acid and alkali metal hydrogen malate, the process comprising:
- (a) providing malic acid particles comprising at least 80 wt. % of malic acid;
- (b) providing sodium hydrogen malate particles comprising at least 80 wt. % of sodium hydrogen malate or potassium hydrogen malate particles comprising at least 80 wt. % of potassium hydrogen malate;
- (c) combining 100 parts by weight of the malic acid particles with either 100-138 parts by weight of the sodium hydrogen malate particles or 200-300 parts by weight of potassium hydrogen malate;
- and 1-10 parts by weight of water;
- (d) subjecting the resulting combination to mechanical shear.
A particulate coating for an edible product wherein the coating comprises a particulate composition comprising at least 1 wt. % of malate particles having a diameter of 50 to 1000 μm and comprising at least 70 wt. % of co-crystal of malic acid and alkali metal hydrogen malate.
