Table 1 Current status of non-heat treatment for raw beef and uncooked processed meat products

Raw material meat Non-heat treatment methods Characteristics after treatment Origin
Beef (chuck) High-pressure processing130/520 MPa10°C, 260 sStorage: 0/1/2/3/4 weeks

■ Metmyoglobin decreases up to 300 MPa

■ Metmyoglobin increases from 301 MPa

■ Brightness increases in the treatment group compared to the control group

■ Microbial inhibition for 7 days at 520 MPa

Jung et al. (2003)
Beef (sirloin) High-pressure processing400/600 MPa5°C, 15 minStorage: 0/4/10/24 h

■ n-hexanal increase at 600 MPa

■ Refrigerated storage recommended for 24 hours to 14 days

Schindler et al. (2010)
Beef (sirloin patty) High-pressure processing300/400/500 MPa25°C, 5 minStorage: 0/2/4/6/8/10 days

■ As the treatment pressure increases, the microbial inhibition effect increases

■ Brightness increased compared to control at 500 MPa

■ Redness decreased compared to control at 500 MPa

Lee et al. (2021)
Beef (sirloin) Gamma-ray3/6/9 kGy

■ 3-9 kGy gamma rays have no effect on pH

■ 3-9 kGy treated was cooking loss decreases compared to the control group

■ 9 kGy treated was shear force decreased, TBARS, and chroma increased compared to the control group

■ More than 3 kGy treated was deoxymyoglobin and metmyoglobin increase

Rodrigues et al. (2020)
Beef (patty) Electron beam2/4/6 kGy25°CStorage: 0/1/3/5/7 months

■ More than 2 kGy treated was the detection of aerobic bacteria, mold, yeast, and coliforms reduced compared to the control group during the storage period

■ When treated with more than 6 kGy, detection of mold and yeast decreases (about 1.1 log CFU/g) during the storage period compared to the control group (about 3.6 log CFU/g) and other treatments (about 2.1 log CFU/g)

Tolentino et al. (2021)
Beef (sirloins) Electron beam 4/8/12/16 kGy Storage: 1/7/14/21 days

■ When treated with 4-8 kGy, brightness, and redness increases, yellowness decreases, and the degree of odor is lower than the control in sensory evaluation

■ 4-12 kGy electron beam has no effect on TBARS
