    摘要： A process for the preparation of histaminase, respectively a histaminase containing material, is described. Histaminase is a diamine-oxidase which metabolizes histamine.According to the process at least one microorganism which produces in its cells histaminase, is cultivated and as soon as a sufficient number of microorganisms has grown, the microorganisms are isolated from the culture medium. Adhering culture medium is removed from the microorganisms and the microorganism cells are broken up and comminuted.The product can be dried in the vacuum, cooled and stored or it can be used to produce products having a higher content of histaminase or to produce a pure histaminase.Preferably a mixture of microorganisms is cultivated which contains at least one microorganism selected from the group lactobacillus and at least one yeast selected from the group candida.The histaminase containing products, respectively the histaminase, are used for metabolizing histamine in foodstuffs, beverages and forages yielding corresponding histamine free products in which the histamine had been metabolized forming not harmful metabolization products.

    摘要： Living cultures of microorganisms used in the preparation of foodstuffs by microbiological processing are protected against attack by bacteriophage viruses by the addition thereto of terpene. The terpene is added in an amount which is effective to obtain viricidal activity but ineffective to cause toxic effects on the microorganisms. The terpene is one obtainable from aromatic plants by steam distillation. Terpenes or mixtures of terpenes which have proved suitable are those obtained from black pepper oil, cinnamon flower oil, cardamon oil, linallyl acetate, cinnamic aldehyde, safrol, carvon and cis/ trans citral, used individually or mixed together. They may added dissolved in a carrier such as 1,2-propanediol. The terpenes demonstrate a viricidal activity in a concentration which is one or more powers of ten lower than the concentration at which the terpenes have toxic effects on the microorganisms.
