Embodiment 1

[0033] Preparation of calcium lactate citrate liquid

[0034] To a 1 liter beaker was added the following components: 409 grams of demineralized water, 104 grams of citric acid monohydrate, 117 grams of L-lactic acid 88%. After the components were completely dissolved, approximately 75 grams of solid Ca(OH) was added slowly while vigorously stirring the reaction mixture 2 . The stirring conditions were 2000 RPM, using a four-paddle impeller, each paddle was 2.5 cm.

[0035] Ca(OH) 2 The addition was continued over the course of less than 5 minutes and the last portion was added slowly in order to adjust the pH of the mixture to about 5.0. After adding Ca(OH) 2 The pH changed from 1.3 to 5.0 during the process. The temperature was raised from room temperature to about 75°C. The resulting liquid was white, opaque and slightly viscous.

Embodiment 2

[0037] Preparation of calcium lactate citrate liquid

[0038] The experiment was performed as described in Example 1, except that the Ca(OH) 2 Added as a suspension in water. The amounts of each substance are: 100 grams of demineralized water, 118 grams of citric acid monohydrate, 139 grams of L-lactic acid 88%, and 417 grams of Ca(OH) 2 30% w / w suspension. The temperature was raised from room temperature to about 70°C. The resulting liquid was white, opaque and slightly viscous.

Embodiment 3

[0040] Preparation of calcium lactate citrate liquid

[0041] A 2 liter baffled vessel was initially filled with 782 grams of 40% w / w Ca(OH) 2 suspension. To this suspension was slowly added 347 grams of 88% lactic acid diluted with 142 grams of water. After the reaction, contains dissolved calcium lactate and suspended Ca(OH) 2 The temperature of this mixture is 70°C. Subsequently, approximately 437 grams of a citric acid emulsion obtained by mixing 295 grams of citric acid monohydrate and 142 grams of water was added to the vessel while vigorously stirring the mixture. The stirring conditions were 1250 RPM, using two six-paddle impellers, each paddle was 2 cm.

[0042] The pH was monitored during the addition of citric acid and the addition of citric acid was stopped when the pH dropped to approximately 5.0. The temperature of the final mixture was maintained at approximately 80°C. The resulting liquid was white, opaque and slightly viscous.

Abstract

The invention pertains to a particulate composition comprising calcium lactate and calcium citrate microparticles having an average diameter from 0.1 [mu]m to 20 [mu]m, wherein the composition is in the form of particles with an average diameter from 25 [mu]m to 1 mm, wherein the ratio by weight of calcium lactate to calcium citrate, based on the dry weight, is 80:20 to 30:70, and wherein the calcium lactate is a non-polymeric agglomeration agent for the calcium citrate microparticles. The invention further relates to a process for producing the particulate composition wherein an aqueous solution of calcium lactate comprising calcium citrate microparticles is spray-dried to the particulate composition, to the use of the particulate composition as calcium-enhancer, and to alimentary products.

Description

Field of Invention [0001] The present invention relates to granular compositions comprising calcium lactate and calcium citrate microparticles. The present invention also relates to a method of producing such a granular composition, to the use of said composition in food and beverages, and to nutritional products. Background of the Invention [0002] Compositions containing calcium are commonly used in foods and beverages to increase their calcium content. [0003] WO 01 / 22838 to Nestle describes a metastable calcium lactate-citrate complex passed between an alkaline calcium source such as calcium hydroxide, calcium oxide, or a mixture of calcium carbonate and lactic acid and citric acid formed by the interaction. This mixture is used to fortify beverages. In an embodiment, the complex is provided as a clear solution. [0004] US 5,186,965 describes a granular composition which is a metastable calcium citrate malate salt. The composition can be prepared by adding a calc...
