  • High trehalose content syrup
    Patent number: 5916881
    Abstract: A non- or substantially non-crystalline high trehalose content syrup, which dissolves trehalose in an amount over the water solubility and dissolves other oligosaccharide having a trehalose structure within the molecule. The oligosaccharide acts as a trehalose crystallization inhibitory agent and makes the syrup stable, free of or substantially free of crystallization at ambient temperature, and free from bacterial contamination. Examples of the oligosaccharide are monoglucosyltrehalose, diglucosyltrehalose, and triglucosyltrehalose.

  • High Trehalose content syrup
    Patent number: 5892026
    Abstract: Disclosed is a non- or substantially non-crystalline high trehalose content syrup, which is supersaturated in trehalose and which further comprises another dissolved saccharide in an amount at least as much as the amount of trehalose. The saccharide acts to prevent crystallization of trehalose. The saccharide may be a reducing monosaccharide, a non-reducing monosaccharide or an oligosaccharide. The supersaturated trehalose solutions are free from bacterial contamination even at ambient temperature.
