Food processing links food production to the provision of food of improved quality and nutrient availability, acceptability, preservation to curtail losses and availability in time of need. To maintain these attributes, a critical look at our local food processing methods is required, with a view to improving it; for instance through the application of modern technology, so as to minimize food poisoning, and improve local food stability. In this review, we wish to highlight the various possible pathogenic poisoning routes of some African food processing methods and possible preventive measures. The food processes involved are fermentation, drying and salting. The source of food contaminant is evidently a portal for contamination by more potent pathogenic microbes, which may cause an epidemic, considering the popularity of the food products. The influx of contaminants; which may be a source of food-borne disease(s), maybe through the original food materials, unhygienic practices of the handlers or the process machinery. The incidence of food poisoning in local food processing can be drastically reduced with improved process operations, increased sensitization of food handlers on their possible contributions to food contamination, regular medical checkups and mandatory certification of vendors, etc. The standard for processing and preparing human food should be improved and researches should be carried out, to ascertain facts and prevent death due to ingestion of poisoned food. Investments in biotechnology should also be made in the most conscious and profound manner, to provide species for better food fermentation processes, and as well, advanced sensitive screening procedures to ascertain contamination, especially by non-culturable microorganisms. Hygienic practices in food processing and preservation are indispensable in food security, as we try to sustain food abundance and minimize food poisoning.

ABSTRACTSalmonellosis is the second most common cause of food-borne illness worldwide. Contamination of surfaces in food processing environments may result in biofilm formation with a risk of food contamination. Effective decontamination of biofilm-contaminated surfaces is challenging. Using the CDC biofilm reactor, the activities of sodium hypochlorite, sodium hydroxide, and benzalkonium chloride were examined against an early (48-h) and relatively mature (168-h)Salmonellabiofilm. All 3 agents result in reduction in viable counts ofSalmonella; however, only sodium hydroxide resulted in eradication of the early biofilm. None of the agents achieved eradication of mature biofilm, even at the 90-min contact time. Studies of activity of chemical disinfection against biofilm should include assessment of activity against mature biofilm. The difficulty of eradication of establishedSalmonellabiofilm serves to emphasize the priority of preventing access ofSalmonellato postcook areas of food production facilities.

Industrial sanitation hygiene education program for crackers home industry workers in Kandangan village, Krembung sub-district, Sidoarjo district was chosen as the Community Work Study Program (KKN-BBM) because: (1) In 2020, in Kandangan Village there were around 52 crackers home industries which has entered the second generation so it must be maintained; (2) The application of sanitation hygiene in the crackers home industry in Kandangan Village is generally still far from the established standards; (3) Poor hygiene practices can cause things that are detrimental to consumers, such as food poisoning or food-borne diseases. The author involved 10 crackers home industry workers as fostered partners during KKN activities taking place in industrial sanitation hygiene education on crackers home industry workers. The program is carried out with the delivery of material regarding sanitary hygiene requirements to control risk factors for food contamination, both those originating of food ingredients, people, places and equipment. To evaluate this activity, pre-test is given before delivering the material and post-test after delivering the material. From the results of the activities, this program has been proven to increase worker’s knowledge regarding sanitation hygiene requirements that must be carried out by crackers home industry managers and workers. Even though industrial sanitation hygiene education activities are more material in nature, it is expected to be a trigger to increase worker’s awareness about the importance of implementing industrial sanitation hygiene and making it a daily habit. This is because one important factor that supports the creation of food security is the condition of good food processing sanitation and hygiene.abstrakProgram edukasi higiene sanitasi industri pada pekerja industri rumah tangga kerupuk di Desa Kandangan, Kecamatan Krembung, Kabupaten Sidoarjo dipilih sebagai program Kuliah Kerja Nyata Belajar Bersama Masyarakat (KKN-BBM) karena: (1) Pada tahun 2020, di Desa Kandangan terdapat sekitar 52 industri kerupuk yang sudah masuk pada generasi kedua sehingga harus dipertahankan; (2) Penerapan higiene sanitasi pada industri rumah tangga kerupuk di Desa Kandangan umumnya masih jauh dari standar yang sudah ditetapkan; (3) Praktek sanitasi higiene yang kurang baik dapat menimbulkan hal-hal yang merugikan konsumen, seperti keracunan makanan maupun penyakit yang ditularkan melalui makanan. Penulis melibatkan 10 pekerja industri rumah tangga kerupuk sebagai mitra binaan selama kegiatan KKN berlangsung dalam edukasi higiene sanitasi industri pada pekerja industri rumah tangga kerupuk.Program ini dilakukan dengan penyampaian materi mengenai persyaratan higiene sanitasi untuk mengendalikan faktor risiko terjadinya kontaminasi terhadap makanan, baik yang berasal dari bahan makanan, orang, tempat dan peralatan.Untuk mengevaluasi kegiatan ini dilakukan pemberian pre-test sebelum penyampaian materi dan post-testsetelah penyampaian materi.Dari hasil kegiatan, program ini terbukti meningkatkan pengetahuan pekerja mengenai persyaratan higiene sanitasi yang harus dilakukan oleh pengelola industri rumah tangga dan para pekerja.Walaupun kegiatan edukasi higiene sanitasi industri lebih bersifat pembekalan materi tapi diharapkan dapat menjadi suatu pemicu untuk meningkatkan kesadaran para pekerja tentang pentingnya menerapkan higiene sanitasi industri serta menjadikannya kebiasaan sehari-hari.Hal ini dikarenakan salah satu faktor penting yang mendukung terciptanya keamanan pangan adalah kondisi sanitasi dan higiene pengolahan pangan yang baik.

Listeria monocytogenes, an opportunistic food borne pathogen can cause serious infections in immunocompromised individuals. L. monocytogenes is capable of producing biofilm on the surface of food processing lines and instruments.The biofilm transfers contamination to food products and impose risk to public health. In the present study biofilm producing ability of L. monocytogenes isolates were investigated phenotypically and genotypically by microtiter assay and multiplex PCR, respectively. Out of 38 L. monocytogenes isolates 14 were recovered from animal clinical cases, 12 bovine environment and 12 from milk samples. A total of 3 (21.42%) clinical, 2 (16.66%) environment and 3 (25%) milk samples respectively, revealed biofilm production in microtiter assay. Cumulative results showed that 23 (60.52%) out of 38 strains of L. monocytogenes were positive for luxS and flaA gene and 1 (2.63%) was positive only for the flaA gene.

Abstract Polygonatum odoratum (Mill.) Druce (POD) is a natural plant widely used for food and medicine, thanks to its rich content of a strong antioxidant agent called homoisoflavones. However, food processing methods could affect the stability of POD flavones, resulting in changes to their antioxidant activity. This study attempts to evaluate the antioxidant activity of POD flavones subject to different processing methods and determines which method could preserve the antioxidant activity of POD flavones. Therefore, flavones were extracted from POD samples, which had been treated separately with one of the four processing methods: extrusion, baking, high-pressure treatment, and yeast fermentation. After that, the antioxidant activity of the flavones was subject to in vivo tests in zebrafish embryos. The results show that yeast fermentation had the least disruption to the antioxidant activity of POD flavones, making it the most suitable food processing method for POD. By contrast, extrusion and high-pressure treatment both slightly weakened the antioxidant activity of the flavones and should be avoided in food processing. The research results provide a reference for the development and utilization of POD and the protection of its biological activity.

Ground-stone tools and hunter-gatherer subsistence in late Pleistocene southwest Asia are examined in light of ethnographic and experimental data on processing methods essential for consumption of various plant foods. In general, grinding and pounding appear to be labor-intensive processing methods. In particular, the labor required to make wild cereals edible has been widely underestimated, and wild cereals were unlikely to have been “attractive” to foragers except under stress conditions. Levantine ground-stone tools were probably used for processing diverse plants. The earliest occurrence of deep mortars coincides with the glacial maximum, camp reoccupations, the onset of increasingly territorial foraging, and the earliest presently known significant samples of wild cereals. Two major episodes of intensification in plant-food processing can be identified in the Levant, coinciding respectively with the earliest evidence for sedentism (12,800-11,500 B.P.) and the transition to farming (11,500-9600 B.P.). The latter episode was characterized by rising frequencies of grinding tools relative to pounding tools, and suggests attempts to maximize nutritional returns of plants harvested from the limited territories characteristic of sedentary foraging and early farming. This episode was probably encouraged by the Younger Dryas, when density and storability of foods may have outweighed considerations of processing costs.

Food Processes

Fundamental, physics-based modeling of complex food processes is still in the developmental stages. This lack of development can be attributed to complexities in both the material and transport processes. Society has a critical need for automating food processes (both in industry and at home) while improving quality and making food safe. Product, process, and equipment designs in food manufacturing require a more detailed understanding of food processes that is possible only through physics-based modeling. The objectives of this paper are (1) to develop a general multicomponent and multiphase modeling framework that can be used for different thermal food processes and can be implemented in commercially available software (for wider use) and (2) to apply the model to the simulation of deep-fat frying and hamburger cooking processes and validate the results. Treating food material as a porous medium, heat and mass transfer inside such material during its thermal processing is described using equations for mass and energy conservation that include binary diffusion, capillary and convective modes of transport, and physicochemical changes in the solid matrix that include phase changes such as melting of fat and water and evaporation/condensation of water. Evaporation/condensation is considered to be distributed throughout the domain and is described by a novel nonequilibrium formulation whose parameters have been discussed in detail. Two complex food processes, deep-fat frying and contact heating of a hamburger patty, representing a large group of common food thermal processes with similar physics have been implemented using the modeling framework. The predictions are validated with experimental results from the literature. As the food (a porous hygroscopic material) is heated from the surface, a zone of evaporation moves from the surface to the interior. Mass transfer due to the pressure gradient (from evaporation) is significant. As temperature rises, the properties of the solid matrix change and the phases of frozen water and fat become transportable, thus affecting the transport processes significantly. Because the modeling framework is general and formulated in a manner that makes it implementable in commercial software, it can be very useful in computer-aided food manufacturing. Beyond its immediate applicability in food processing, such a comprehensive model can be useful in medicine (for thermal therapies such as laser surgery), soil remediation, nuclear waste treatment, and other fields where heat and mass transfer takes place in porous media with significant evaporation and other phase changes.

[Introduction]. Food-borne diseases (FBDs) are one of the most frequent public health problems in daily life. The hazards that cause FBD may occur in the different stages of the food chain (from primary production to the table). Independently from its origin, once the food reaches the consumer it may have an impact on public health and cause severe economic damage to the establishments devoted to its preparation and sale. These two events may cause loss of confidence and the closing down of a business. Fortunately, the measures for preventing food contamination are very simple and may be applied by anyone who handles food, by following easy rules for hygienic food handling. This Manual’s purpose is to provide to people who handle food, and particularly to food-handlers’ instructors, the information they need to facilitate the teaching of proper procedures to food workers. In addition, it seeks to provide basic information about food safety that Latin American and Caribbean countries may adapt to their own needs. The Manual is organized into three Modules and Appendixes focusing on the following topics: (1) food hazards; (2) FBDs; and (3) hygienic measures to prevent food contamination. The evaluation at the end, forms part of the Manual. Its purpose is to assess the knowledge learned during the course regarding the importance of hygienic food handling for public health.
