Histidine Decarboxylase Activity

The histidine decarboxylase activity of Enterobacter cloacae S15/19 was studied during the production process of salchichón, a Spanish ripened sausage. Counts of fecal coliform and histidine decarboxylase bacteria decreased during the production process, showing a good correlation in both inoculated and control samples. In the samples inoculated with Enterobacter cloacae S15/19, fecal coliforms were undetectable the last day of the survey, while the population of histidine decarboxylase bacteria was over 2 log MPN/g. Despite the fact that inoculation with Enterobacter cloacae S15/19 increased histidine decarboxylase bacteria counts, no differences were observed in the histamine concentration reached, which was undetectable in most of the control and inoculated samples. In contrast, cadaverine concentration increased significantly (P < 0.01) in the inoculated samples, suggesting that cadaverine could be used as a hygienic-quality indicator of the raw materials employed in sausage processing.

Histidine Decarboxylase Activity

The distribution of mast cells in muscle and liver of dystrophic mice was studied; histamine and histidine decarboxylase activity was also measured in the same tissues. Mast cells were significantly more numerous in dystrophic muscles. On the other hand, very few cells could be counted in the liver of either control or dystrophic animals. Histamine concentration was higher in muscle and liver of dystrophic mice; no visible increase in histidine decarboxylase activity could be measured by the methods used. It is concluded that histamine-binding capacity is increased in some tissues of dystrophic mice.

Histidine Decarboxylase Activity

The histamine content and the histidine decarboxylase activity of bone marrow have been studied in guinea pigs treated with foreign protein. In some experiments the effect of 6-methylprednisolone also was observed. Treatment of guinea pigs with foreign protein resulted in a 10-fold increase of both histamine concentration and histidine decarboxylating activity in the blood and bone marrow. Histamine levels and histidine decarboxylating activity were related to the number of basophils. A fairly constant relationship was found between the histamine content and the enzyme activity per basophil. The findings suggest that histamine is formed and to a certain extent also stored in the basophilic leukocytes.

Histidine Decarboxylase Activity

The effects of different types of stress (water bathing, cold, restraint, and prolonged walking) on histidine decarboxylase (HDC) activity in masseter, quadriceps femoris, and pectoralis superficial muscles, and in the stomach were examined in mice. All of these stresses elevated gastric HDC activity. Although water bathing, in which muscle activity was slight, was sufficiently stressful to produce gastric hemorrhage and to increase gastric HDC activity, it produced no detectable elevation of HDC activity in any of the muscles examined. The other stresses all elevated HDC activity in all three muscles. We devised two methods of restraint, one accompanied by mastication and the other not. The former elevated HDC activity in the masseter muscle, but the latter did not. These results suggest that 1) HDC activity in the stomach is an index of responses to stress, 2) the elevation of HDC activity in skeletal muscles during stress is induced partly or wholly by muscle activity and/or muscle tension, and 3) stress itself does not always induce an elevation of HDC activity in skeletal muscles.

Monitor And Control

The procedure of traceability of finished product, the regulating actions for tracking of products, beginning from the raw materials used for production of the single-part randomly chosen consumer package of a product and ending with shipment of this product to distributing facilities and also for tracking of processing of randomly chosen raw materials are offered. The traceability system does not guarantee a complete elimination of risk from arrival to the enterprise of improper raw and other materials, but allows tracking and identifying a source of nonconformance, after receiving of problem in quality of finished product. If a source of nonconformance is raw or other materials, then the manufacturer can allocate responsibilities for damage to property to the supplier of these raw or other materials. The procedure of traceability provides carrying out of training exercises at least once a year for determination of efficiency and working capacity of the current system of traceability, and also for identification and elimination of bottlenecks. For monitor and control over the stages of a process flow on the basis of the available database were proved the critical parameters of production process of confectionery, which control will allow to receive a safe product with the set technological and end-user performances. For monitor and control over the stages of a process flow on the basis of the available database on product traceability were proved the critical parameters of production process of confectionery, which control will allow to receive a safe product with the set technological and end-user performances. The accepted system eliminates a possibility of sales of products of nonconforming quality and allows to go back from the established control procedures that promotes the productivity enhancement.
