  • Patent number: 5464644
    Abstract: A ready-to-eat cereal product contains a substantial portion of typical cereal grain component, such as bran, wheat and the like, together with a therapeutic quantity of psyllium. The quantity of psyllium is sufficient to reduce the cholesterol level of humans and animals when part of the diet. The psyllium may be added as an intermediate psyllium product prepared by directly expanding psyllium husks, either by itself or together with minor amounts of other ingredients. The psyllium intermediate is preferably added during the process for making the final cereal product after the typical cereal grain components have been totally or partially cooked.

  • Patent number: 5271936
    Abstract: Disclosed is a method of reducing the allergenicity of psyllium seed husks and psyllium seed husk-containing food additives. The method comprises subjecting ground psyllium seed husks to a wet heat treatment for a time and at a temperature and pressure sufficient to reduce the allergenicity of the psyllium seed husks. Psyllium seed husks alone can be subjected to the wet heat treatment to reduce its allergenicity and subsequently used as an ingredient to produce a psyllium-containing food additive or food product. Alternatively, psyllium seed husks can be mixed with one or more other ingredients of a food additive or food product and then subjected to the wet heat treatment during production of the food additive or food product.

  • Patent number: 5270063
    Abstract: This invention provides for a cereal composition, particularly in a ready-to-eat cereal, that contains beta-carotene (BC) in an amount ranging from about 0.001% to about 0.02% based on the dry weight of the cereal composition. The beta-carotene may be incorporated in the form of water insoluble beadlets or may be added in a soluble form with a sweetening agent during manufacture of the composition. The cereal composition containing BC retains good stability, and normal color, flavor and aroma characteristics as compared with analogous cereal compositions without beta-carotene.
