Amid the health-oriented upgrade of the beverage industry, being preservative-free has become a core selling point for strawberry jam and other beverage bases-yet it has left numerous businesses facing operational challenges: preservative-free jam spoils easily at ambient temperature, with short shelf life leading to high waste; relying on cold chain storage and transportation, on the other hand, drastically increases operational costs.
The core key to achieving a 6-month ambient shelf life for preservative-free strawberry jam lies in building a processing closed loop of commercial sterility + aseptic sealing with professional equipment. With 20 years of experience in fluid food processing equipment, Shanghai Chase focuses on the fluid food processing field such as coffee and tea beverages. We provide a scientific and actionable solution for this demand with a full-process equipment combination of crushing & beating, high-temperature sterilization, and aseptic filling.
Core Shelf Life Logic: Block Microbial Growth from the Source
The industry consensus for achieving long-term ambient shelf life of preservative-free food is to eliminate microorganisms from the source and block secondary contamination. As a berry-based fluid food, strawberry jam has pulp rich in water and sugar, making it a prime environment for microbial growth. Its processing requires both efficient sterilization and retention of fresh fruit flavor-traditional boiling and simple processing methods struggle to balance the two, while the professional equipment chain built by Shanghai Chase is precisely adapted to the processing characteristics of strawberry jam.
Full-Process Equipment Solution: Build an Aseptic Processing Closed Loop
Shanghai Chase's customized equipment solution for strawberry jam processing forms a complete processing closed loop from raw material treatment to aseptic freshness locking.
1. Raw Material Treatment: The crusher efficiently crushes strawberry raw materials, and the refined beater achieves precise pomace-juice separation. While retaining the grainy texture of strawberry pulp, it ensures a uniform jam consistency, laying a solid foundation for subsequent aseptic processing.
2. Core Sterilization: The tubular sterilizer is equipped with 120+℃ ultra-high temperature instant sterilization technology, featuring precise temperature control and high sterilization efficiency. It can quickly eliminate pathogenic bacteria to meet commercial sterility standards. Meanwhile, the instant sterilization process minimizes damage to the flavor and nutrition of the jam, aligning with the beverage industry's core demand for freshness.
3. Aseptic Filling: Aseptic BIB (Bag-in-Box) filling machines and aseptic bulk bag filling machines automatically complete the entire process of bag feeding, filling and sealing in an aseptic environment, completely blocking the invasion of external microorganisms. Filled products can be stored at ambient temperature for energy saving and are easy to transport, fundamentally solving the problem of secondary contamination.
