An object of the present invention is to provide an &#x3b1;-glucan mixture in a preferable molecular weight range, which can be made into a transparent film with advantageous strength and water solubility when an edible film is made by using the &#x3b1;-glucan mixture without adding any plasticizer. The above object is solved by providing an &#x3b1;-glucan mixture, which is obtainable by a process comprising the steps of gelatinizing waxy starch and liquefying the resulting gelatinized waxy starch by allowing an amylase to act on it, having the following characteristics (1) and (2):

Alpha-glucan mixture, its preparation and uses

An object of the present invention is to provide a novel starchy substance having a retrogradation-resistance, a process for producing the starchy substance efficiently from a material starch by enzymatic reaction, and uses thereof. The present invention attains the above object by providing branched starch having 6-&#x3b1;-maltosyl- and/or 6-&#x3b1;-maltotetraosyl-structure(s) with a marked retrogradation-resistance, a process for producing the branched starch without lowering the molecular weight of material starch, and uses thereof.

Highly-branched starch, its production and uses

A protein having a molecular weight of 44,000-54,000 daltons, isoelectric point of 8.5-9.2 and specific sugar chain is prepared from a cedar pollen. The protein induces pollenosis and can be suitably used as desensitization agent because it induces immunoglobulin antibody which is effective for desensitization, but does not substantially induce immunoglobulin E antibody, a major factor causative of side effects including anaphylaxis shock. Therefore, the protein can be advantageously used in the treatment, prevention and/or diagnosis of pollenosis.
