Abstract: Low acid heat-sensitive foodstuffs, such as low acid heat-sensitive vegetables and cereal grain products, are thermally processed in the presence of a mixture of an acid and its lactones, preferably an aldonic acid with its lactones, the acid of which makes possible a condiderably reduced commercial sterilizing parameter (i.e. lower temperature and/or time) whereby more of the flavor, color, or texture of the foodstuff is retained, and is closer to that of the freshly harvested home-cooked product, compared to the foodstuff processed at a more severe parameter when the acid is not employed. The type and level of the acid employed and its presence with its lactones results in a thermally processed foodstuff which does not have an objectionable acid taste. The preferred mixture is gluconic acid with its lactones, glucono-delta lactone and glucono-gamma lactone, provided to the foodstuff by combining it with a precursor of gluconic acid, preferably glucono-delta lactone.

Abstract: When display data are written into the terminal's display memory (17), the data indicative of the display coordinate are converted from the normalized values to the absolute values of the NTSC system or PAL system and are then written into the corresponding addresses of the display memory (17), so that regardless of the fact that the display is of the NTSC system or of the PAL system, the figure can be displayed with the correct aspect ratio. Further, when the coordinates are converted, the conversion is carried out such that the display resolution is regarded as the highest one, so that even if the resolution of the display is increased by increasing the capacity of the display memory (17), it is not necessary to change the conversion algorithm. For displays having less than full resolution capability, the display data is scaled by omitting some of the converted data when writing it into the display memory (17).
