Summary
Central kitchens require efficient fresh food pretreatment technologies. This review covers ultrasonic cleaning, physical-field inactivation, non-thermal disinfection, and modified atmosphere packaging to enhance food processing.
Area of Science:
- Food Science and Technology
- Agricultural Engineering
Background:
- Centralized food preparation (central kitchens) is a growing trend in the food industry.
- Fresh foods like produce, meat, and seafood require careful processing due to high water content and heat sensitivity.
- Current pretreatment methods often face challenges in efficiency, automation, and nutrient retention.
Purpose of the Study:
- To systematically review novel, high-efficiency pretreatment technologies for fresh foods in central kitchen settings.
- To analyze the mechanisms, applications, and limitations of these advanced technologies.
- To identify solutions for common central kitchen processing issues.
Main Methods:
- Review of existing literature on advanced food pretreatment technologies.
- Analysis of ultrasonic cleaning, physical-field enzyme inactivation, non-thermal disinfection, and modified atmosphere packaging/coatings.
- Discussion of influencing factors, advantages, and disadvantages of each technology.
Main Results:
- Ultrasonic cleaning offers improved efficiency and automation potential.
- Physical-field and non-thermal methods show promise for enzyme inactivation and disinfection with reduced nutrient loss.
- Modified atmosphere packaging and coatings can extend shelf life.
Conclusions:
- Advanced pretreatment technologies are crucial for improving central kitchen efficiency and product quality.
- Addressing issues like low efficiency, nutrient loss, and short shelf life is key for modern food processing.
- These technologies pave the way for next-generation fresh food processing systems.

01:23Physical Methods for Controlling Microbial Growth: Temperature
821
Heat is a widely used method to control microbial growth by targeting and denaturing cellular proteins, thereby killing or inactivating microbes. This method's effectiveness is quantified using parameters such as the thermal death point (TDP), thermal death time (TDT), and decimal reduction time (D value). TDP represents the lowest temperature at which all microorganisms in a liquid suspension are eliminated within 10 minutes, whereas TDT is the time necessary to achieve sterilization at a...

01:26Physical Methods for Controlling Microbial Growth: Radiation and Filtration
888
Radiation and filtration are essential tools for microbial control, targeting microorganisms through distinct mechanisms. Radiation eliminates microbes by damaging their DNA, either killing them or inhibiting their growth. Based on wavelength, radiation is classified into two types: nonionizing and ionizing radiation.Non-ionizing radiation, such as UV radiation (200–400 nm), is absorbed by DNA, causing defects that effectively disinfect surfaces, air, and water, including safety cabinets.

In healthcare, the chemical method of sterilization uses chemical sterilants to treat surgical instruments and medical supplies to help prevent the transmission of infectious pathogens to patients. Due to heat sensitivity, most medical supplies and equipment should not be exposed to high temperatures. These parts include rubber, plastic, glass, and other similar elements.

As used in a healthcare facility, sterilization destroys all microorganisms through physical or chemical methods. The physical method includes steam, dry heat, boiling water, and radiation.
Steam sterilization uses non-toxic, low-cost moist heat in the form of saturated steam under pressure, which is fast, microbicidal, and sporicidal, and quickly warms and penetrates fabrics. Autoclaves, or steam sterilizers, expose each item to direct steam contact for a predetermined time at the necessary...
