ExpertKai Expert's formal training and industrial experience have provided him a solid foundation to design optimal heat sterilization processes for foods, pharmaceuticals, devices, biologics, and equipment. His activities in this field include low-acid canned foods, in-container or terminal heat sterilization of drugs, and process R&D to minimize chemical degradation of products, trauma to container-closure systems, and post-process contamination.

ExpertPurohit has expertise in high-pressure processing for pasteurization and/or sterilization of foods and pharmaceuticals, and with high and ultra high temperature short time (HTST) process equipment for food and pharmaceutical processing for aseptic and terminal use.

One of the classic techniques of process optimization involves sterilizing products and packages, both separately and independently, bringing the

The dictates of increasing functional and efficacous product requirements have guided ExpertPurohit into researching and developing alternate modalities for sterile manufacture. Amongst them are processes involving microwaves, UV, ultrasonics, supercritical extraction and E-beams, as well as techniques involving modified atmospheres, hurdles, and active packaging. Maintenance of seal integrity and its non-destructive monitoring has been a natural extension of these activities.

The need to protect workers from their work, and the work from the workers, has triggered the development of numerous technologies in modular, flexible, and portable biological barriers. The challenge of pre-sterilizing these isolators or bubbles and the maintenance of their sterility, while permitting transfers "in" and "out," have required ExpertPurohit to focus on the development of several cold sterilization and contamination control technologies that have wide applicability in sterile manufacture of foods and drugs.

While ionizing radiation like gamma, and more recently E-beams, have held the attention for sterilization and pasteurization in the food, pharmaceutical, and device industries, the use of non-ionizing energies like UV, ultrasonics, pulse power, and microwaves have shown great promise. ExpertPurohit's activity has required him to develop techniques to minimize radiation damage by optimizing the use of E-beams, as well as niche applications for UV and microwave energies su

ExpertPurohit is well-versed in the ethylene oxide sterilization of food spices and medical devices; peracetic acid and/or hydrogen peroxide sterilization of isolators, enclosures, and surfaces; ozone sterilization of water; membrane filter sterilization of fruit juices and labile drugs; and UV and ultrasonic sterilization processes. His expertise also includes plasma, H2O2, and PAA sterilization of reusable medical devices such as "scopes."
