Abstract: The present invention is to provide a two-stage sterilization process for treating heat-resistant spores in a great burdock extract drink, which comprises the steps of sealing dried great burdock and water in a double-kettle pressure cooker; heating liquid mixture of great burdock and water to a first temperature range lower than or equal to 100° C. for at least a first duration during a first-stage sterilization; opening lid of the cooker and filtering out great burdock residue so that all that remains in the cooker is great burdock extract; resealing the cooker and heating the great burdock extract to a second temperature range higher than or equal to 120° C. for at least a second duration during a second-stage sterilization, and the pressure in the cooker during the second-stage sterilization is higher than that during the first-stage sterilization; so as to obtain the extract drink free of common bacteria and heat-resistant spores.

Abstract: A particle embedded with chemical substances, especially with physiological activity substances, is disclosed. The particle has (a) the embedded substances, embedded in base materials and ranged from about 0.1 to 70% by weight based on the total weight of the particle; and (b) the base material, selected from hydrogenated plant oil, hydrogenated animal oil, C8-C64 saturated fatty acid or the derivatives thereof, and ranged from about 30 to 99.9% by weight based on the total weight of the particle. Also, the present invention discloses a method for producing the particle.
