Other advances in Australian fish technology have been listed by J. R. Vickery as follows:[165] the definition of the conditions of handling and storage of shark flesh to prevent the enzymatic conversion of intrinsic urea to ammonia giving rise to 'ammonia taint'; the setting of processing procedures required to prepare canned northern blue fin tuna comparable in quality with southern blue fin; the establishment of the conditions leading to the formation of formaldehyde in fish muscle; the definition of the methods of handling, freezing and storage of rock lobsters; the control of microbial contamination of oysters; and the establishment of the conditions for the chilled storage of scallops.When more sensitive methods of analysis led to the identification of Minamata disease with mercury poisoning from fish, surveys revealed the widespread presence in fish of mercury at low concentrations. Some such work was done in Australia in government and industry laboratories and an important report was prepared for the guidance of industry and the regulatory authorities.[166] Much tougher regulations followed and limits for other heavy metals were closely scrutinized also.
During the 1970s Davis Gelatine developed a continuous extraction process for making top quality food grade gelatin from cattle skins. The process and equipment were designed to optimize the molecular weight of the gelatin and its purity for food use and thus to yield a product with improved properties at a lower cost. The special merit of the process is its ability to produce a consistent product from skins gathered from all over Australia. This advanced Australian technology has now been transferred to New Zealand and South America.[167]
