Heat Sterilization Conditions to Ensure Commercial Sterility of Hot-Filling Tomato Juice

The Sterility and Sterilization of Lung Ventilators.

Intermittent positive pressure breathing machines are in use for the treatment of many respiratory and cardiac conditions, but there is no agreement regarding the risk of cross infection and the necessity of sterilizing part, or all, of this equipment. Until recently, complete sterilization has been difficult to effect, and so reliance has been placed on boiling or chemical disinfection of the ...

effect of storage conditions on the quality of tomato juice

present study examined the effect of storage conditions (packaging type, storage temperature and time) on physicochemical and microbial properties of tomato juice. samples were stored for one and three months in two packaging types (bottle and doypack) at 4, 25 and 35oc. results obtained from testes (ph changes, acidity, solid soluble content, vitamin c content, and microbial load) showed that ...

Sterilization by dry heat.

The advantages and disadvantages of three forms of dry heat sterilization are discussed. In addition a fourth method, consisting of heating by infrared rays in vacuo, is described. This method is particularly suitable for instruments used in the operating theatre, since it can replace an autoclave where a supply of steam is not available. Recommended times and temperatures for dry heat steriliz...

Sterility testing: the control of efficiency of sterilization techniques.

During the course of an investigation of cotton for use as air filters on the needles of bleeding units, a heat-resistant, spore-forming organism was isolated. Because of its unusual degree of heat resistance, the organism appeared to be more suitable as a control of the efficiency of sterilization than species of Clostridium usually employed for this purpose. Experiments were undertaken to det...
