  • Patent number: 10479812
    Abstract: The present invention relates to maltooligosaccharides, the content of ?-1,4-glycosidic bonds of which is between 70% and 80% of the total number of 1,4-type glycosidic bonds. The invention also relates to the method for manufacturing these maltooligosaccharides. Said maltooligosaccharides afford all the benefits of fiber-based foods, with an extremely low nutritional value. Such a compromise is particularly advantageous for use in healthy balanced diets, but also in the treatment and/or prevention of the pathology of diabetes. The invention also relates to the use of said maltooligosaccharides in the fields of human food and animal feed.

  • Patent number: 10478765
    Abstract: A method for in-line control of the integrity of a filtering system implemented during an industrial process including the filtering of a gas through the filtering system, the filtering system including at least one filtering cartridge, the method including at least the following steps: —a measurement step (S1) which involves measuring a pressure difference ?P representative of the pressure loss caused by the filtering system (F1; F2), —a testing step (S2, S3) which involves comparing the measurement (S1) with a predefined high threshold (Sh) and a predefined low threshold (Sb), in such a way as to consider the at least one filtering cartridge to be non-compliant when the pressure difference measured in the measurement step (S1) falls outside a range located between the high threshold (Sh) and the low threshold (Sb).
