  • Publication number: 20250008986
    Abstract: The present disclosure relates to a method for producing pulp-containing juice, which may produce pulp-containing juice without loss of nutrients while maintaining the flavor and color of a raw material. The method includes squeezing raw material for juice to obtain juice and sterilizing the juice by non-thermal high-pressure processing. Thus, the method may inactivate microorganisms or enzymes, maintain the quality of the juice in a fresh state, and prevent the flavor and nutrients of the raw material from being lost by high-temperature sterilization. In addition, through a quick freezing process, it is possible to prevent the layer separation phenomenon from occurring, prevent the nutrients from being destroyed by temperature changes, and maintain the uniform color of the pulp-containing juice even without using a colorant. A user can conveniently drink the pulp-containing juice produced by this method while feeling the flavor of the fruit thereof without loss of nutrients.

  • Patent number: 8741162
    Abstract: Methods of manufacturing a nanoimprint stamp are provided. The method may include forming a pattern on a surface of a master substrate, depositing an etch barrier layer on a surface of a stamp substrate, coating a photoresist on one of the surfaces of the master substrate and the stamp substrate on which an etch barrier layer is formed, forming a photoresist pattern by pressing the master substrate against the stamp substrate, forming a hard mask by etching the etch barrier layer using the photoresist pattern, and etching the stamp substrate using the hard mask as an etch mask.
