IDENTIFICATION AND RISK CONTROL OF THE HACCP SYSTEM IMPLEMENTATION IN THE PASTEURIZED CRAB PRODUCTION PROCESS

Background: In the production process, small accidents often occur between fellow workers in the production area, such as workers colliding with each other during the transfer process from one process to the next which causes the product to spill and workers fall, causing injury. PT. XYZ is a company engaged in the seafood industry, especially canning crabs. The company's production process applies a Good Manufacturing Practice (GMP) system with 12 work areas and 80% of the process is still done manually. Purpose: The purpose of this study is to identify risks and control the implementation of the HACCP system in the crab canning industry using the HAZOP method. Method: This type of research is a descriptive study, using the HAZOP (Hazard and Operability) method. The research was carried out at 12 nodes, namely receiving, checking aroma, sorting, mixing and filling, metal detecting, weighing, seaming, pasteurization, chilling, packing, and sanitation. Result: The results showed 4 risk ratings, namely low, medium, high, and extreme risk based on 8 sources of potential hazards. The biggest risk that is extreme is in node seaming. Conclusion: Based on processing data, 8 sources of potential hazards that can occur in the pasteurized crab meat production room. The recommendations given are to implement elimination, reduction, engineering control, administrative control, Personal Protective Equipment, work attitude improvement, and OHS training.

Improving of Gelling Capacity of Cooked Crab Meat Proteins

Cooked crab meat subjected to a cutting process can aggregate again, forming weak gels. The objective of this work was to determine the effect of two mixing methods, combined with the addition of the microbial enzyme TGase (MTGase) on the mechanical and functional properties of gels from washed or unwashed blue crab (Callinectes sapidus) meat. Live crabs were obtained from Laguna Madre, Tamaulipas, Mexico, and cooked at 120°C for 20 min before hand-picking the meat from the shell. Cooked meat was processed by mixing and cut at temperatures of 25 or 60°C, without (control) or 0.5% of MTGase. Then cooked at 90°C for 15 min. Changes in texture profile analysis, percentage of extractable water, and color were evaluated. The mixing method at 60°C allowed increasing the textural properties of the gels, and the addition of MTGase significantly improved the mechanical properties. The results allowed stablishing a viable technique to obtain restructured gels from cooked crab meat with no need to extract the soluble compounds responsible for their distinctive odor and taste which often affect the mechanical properties.

Effect of different sterilization methods on sensory quality and volatile flavor of flavor crab meat sauce

Flavor crab meat sauce (FCMS) is a new type of aquatic condiment that is not only rich in nutrition but also unique in terms of flavor. However, very little is known about how sterilization methods affect the sensory quality and volatile flavor of FCMS. In the present study, canned FCMS was subjected to the following sterilization methods: pasteurization (PS), microwave sterilization (MS), ultrasonic sterilization (US), and high temperature sterilization (HTS). Each sterilization method was evaluated on the basis of texture, color, sensory score, volatile flavor, and total viable counts in FCMS observed after sterilization. Results demonstrated that the total viable count decreased to 28, 26, 58, and 18 CFU/g respectively after PS, MS, US, and HTS treatments; no coliform group was detected in any of these samples. PS and MS had no significant effect on the texture of FCMS (P > 0.05), but US and HTS reduced hardness and viscosity of FCMS. MS and HTS significantly reduced the L*, a*, and b* values of FCMS (P < 0.05). The original brightness and red value of FCMS remained the same after PS and US. MS and HTS reduced the sensory score of FCMS to a great extent, while PS and US maintained the original sensory score of FCMS. Assessment of volatile flavor profile of FCMS post different sterilization treatments revealed that MS and HTS reduced the total ester content, while US reduced the total amount of alcohols in FCMS. However, PS not only maintained the original total amount of esters in FCMS, but also increased the content of alcohols, aldehydes, and ketones. Therefore, PS could be selected as a feasible sterilization method for FCMS among the four different sterilization methods.

Food-borne outbreak of Listeria monocytogenes in school students in Seoul, Korea

In September 2018, an outbreak of Listeriosis cases in Korea was traced to food involved, using retrospective cohort studies and PFGE analyses. This study aimed to describe the first L.monocytogenes outbreak identified in Korea. We confirmed the presence of Serovar (4C) and virulence genes, and evaluated the genetic correlation between isolates by restriction digestion patterns of ApaI and AscI. Based on the epidemiological association, it is presumed that the seasoned crab meat with bean sprouts are contaminated by cross contamination during the bean sprouts washing (relative risk was 1.24; p-value: 0.0021 and they possessed virulence genes. Therefore, active laboratory surveillance is necessary to recognize the risk of L. monocytogenes in Korea.
