“…The cold chain of fresh meat products can be divided into two types in accordance with temperature limits. One is the frozen cold chain, at temperatures of approximately −18 °C, and the other is the chilled cold chain, at temperatures of approximately 0 °C (Abad et al, ; Margeirsson et al, ). Through site visits at a slaughterhouse, a meat processing factory, and a meat company called Food Co., Ltd. in Beijing, information was gathered about the cold chain and is presented in a detailed flow analysis in Figure .…”

Fresh pork is a meat that many people choose to eat in daily lives, and it is becoming more important to devise a method for ensuring the quality and safety of fresh pork. Combined with the meat quality of the cold chain and the environmental information collection program, this study presents a QR code based tracing method for a quality tracing system. This method includes a correction recognition test for the final design of the QR code. The results show that QR code can store large amounts of traceability information, with strong error correction capability, and can provide a great advantage in scanning recognition. In the process of consumption, consumers can easily obtain fresh pork quality information by scanning the QR code with a mobile phone, rather than having to choose a piece of meat to purchase based only on a visual observation of the meat. Practical applications In this study, the design of the temperature acquisition scheme was verified in SMEs (small and medium enterprises), the results show that the data transmission is stable. The generated QR codes were tested in some supermarkets, have strong error correction capability, and can meet the retroactive requirements. According to this research, when the damage to the traceability barcode is beyond the range of 30% before the barcode enters circulation, the barcode needs to be reprinted.

“…The effects of temperature abuse on quality of fish products during storage and transportation have been described in several studies (Sigholt and others ; Olafsdottir and others , ; Lauzon and others ; Margeirsson and others , ). However, information on the influences of time‐temperature abuse during processing on fillet temperature and quality is scarce.…”

“…Processing time is crucial since the individual fish and products are exposed and may warm up quickly. For instance, cod fillet temperature increases by 6 to 7 °C after 1 h exposure to a 20 °C environment (Margeirsson and others , , ).…”

The observations show the importance of maintaining a low temperature in fish, even for a short period such as during processing. Any delays, such as due to buffering or mechanical failure, may accelerate spoilage of chilled products during subsequent storage. This effect is even more pronounced when products are packed in bulk volumes as the cooling rate is much slower than the piece-by-piece cooling rate.

“…However, experimental work should accompany these methods to develop accurate modeling. Margeirsson et al [29] developed a 3D heat transfer model that could be used to predict product temperature changes in supercooled cod fillets packaged in loaded EPS boxes. The developed model was validated by comparing with experimental results, and was slightly different from the experimental results.…”

The main purpose of cold chain is to keep the temperature of products constant during transportation. The internal temperature of refrigerated truck body is mainly measured with a temperature sensor installed at the hottest point on the body. Hence, the measured temperature cannot represent the overall temperature values of transported products in the body. Moreover, the airflow pattern in the refrigerated body can vary depending on the arrangement of loaded logistics, resulting temperature differences between the transported products. In this study, the airflow and temperature change in the refrigerated body depending on the loading patterns of box were analyzed using experimental and numerical analysis methods. Ten different box loading patterns were applied to the body of 0.5 ton refrigerated truck. The temperatures inside boxes were measured depending on the loading patterns. CFD modeling with two different turbulence models (k-ε and SST k-ω) was developed using COMSOL Multiphysics for predicting the temperatures inside boxes loaded with different patterns, and the predicted data were compared to the experimental data. The k-ε turbulence model showed a higher temperature error than the SST k-ω model; however, the highest temperature point inside the boxes was almost accurately predicted. The developed model derived an approximate temperature distribution in the boxes loaded in the refrigerated body.
