  • Patent number: 11083808
    Abstract: An improved pasteurisation protocol for pasteurising microbial cells is disclosed. The protocol has three stages, a first heating stage, a second plateau stage at which the cells are held at a (maximum and) constant temperature, and a third cooling stage. Both the heating and the cooling stages are rapid, with the temperature of the cells passing through 40 to 80° C. in no more than 30 minutes in the heating stage. The heating rate is at least 0.5° C./minute and during cooling is at least ?0.5° C./minute. The plateau maximum temperature is from 70 to 85° C. By plotting the pasteurisation protocol on a time (t, minutes) versus temperature (T, ° C.) graph, one obtains a trapezium having an area less than 13,000° C. minute. Not only does this result in a smaller energy input (and so a reduction in costs), but a better quality (and less oxidised) oil results having a peroxide value (POV) of less than 1.5 and an anisidine value (AnV) of less than 1.0.

  • Patent number: 11058634
    Abstract: An oral pharmabiotic system is disclosed for improving oral, dental, and systemic health by repopulating and reshaping the flora within a patient's oral environment in a manner that overcomes the deficiencies of prior oral probiotic products. By formulating the pharmabiotic system as a strip for adhesive placement within a patients' oral cavity, preferably against the buccal mucosa, alveolar mucosa, oral labial mucosa, or a dental appliance, and configuring the parameters of the strip such that neither disadhesion nor complete dissolution occurs for at least a period of at least three hours during daytime use and at least six hours during nighttime use, the probiotic payload contained within may remain in the oral cavity for a sufficient length of time required for the probiotics to activate, replicate, and displace existing harmful oral pathobiotics.
