Product Introduction
Isomalt, a sugar alcohol, is derived from sucrose. It is composed of two different disaccharides, glucosyl-sorbitol and glucosyl-mannitol [1]. Isomalt is valued for its low hygroscopicity and sucrose-like taste profile [2]. This sweetener is approximately 45-65% as sweet as sucrose [3]. Isomalt is produced through a two-stage process involving enzymatic conversion of sucrose to isomaltulose, followed by catalytic hydrogenation [4]. Its stability allows it to be used in various applications, from hard candies to baked goods.
Product Manufacturing Process
The manufacturing of isomalt involves two primary steps: enzymatic conversion and catalytic hydrogenation. The first step begins with sucrose, which is enzymatically converted into isomaltulose, using an enzyme such as isomaltulose synthase [4]. Next, the isomaltulose is purified and then hydrogenated, typically using a nickel catalyst, to produce a mixture of glucosyl-sorbitol and glucosyl-mannitol [4]. The resulting isomalt is then crystallized, dried, and milled to achieve the desired particle size [4]. Stringent quality control measures are implemented throughout the process to ensure purity and consistency [4].
Product Applications
Isomalt finds use in various food applications, particularly where sugar-like properties are desired with reduced caloric content. It is commonly used in sugar-free candies, chewing gums, and chocolates because of its low hygroscopicity, which prevents stickiness [5]. In baked goods, isomalt can add bulk and texture while contributing less to the overall sweetness [6]. Pharmaceutical applications include its use as a coating agent and excipient in tablets [7]. Isomalt’s stability under different processing conditions makes it a versatile ingredient for various formulations [8].
Packaging and Storage
Isomalt is typically packaged in multi-layer paper bags or fiber drums with polyethylene liners, available in various sizes such as 25 kg or 50 lb [9]. It should be stored in a cool, dry place, away from direct sunlight and moisture to maintain its quality and prevent clumping [9]. Proper storage conditions ensure that isomalt retains its properties and extends its shelf life [9]. Following these guidelines helps prevent degradation and maintains product integrity during storage [9].
