- The inhibitory effects of cassia oil on the human pathogen Escherichia coli serotype O157:H7 and the plant pathogen Botrytis cinerea were tested in vitro at different concentrations (200-800 ppm). Cassia oil exhibited antibacterial and antifungal activity against both pathogens. Cassia oil at 400-800 ppm inhibited the growth of E. coli O157:H7 in vitro and on the surface of treated strawberries. Cassia oil also completely inhibited the growth of B. cinerea at 400-800 ppm. Spore germination and germ tube elongation of the pathogens in potato dextrose broth were strongly inhibited in the presence of 100 ppm cassia oil. Cassia oil at all concentrations reduced the percentage of decayed strawberries. Experiments on reducing the development of natural decay in strawberries gave similar results. None of the quality parameters tested (colour, total soluble solids, pH, total acidity and ascorbic acid) was affected by cassia oil treatment. Storage experiments on strawberry showed that the percentage weight loss was reduced by cassia oil treatment. Hence, cassia oil could be an alternative to synthetic chemicals for controlling human and plant pathogens on fruits such as strawberries during postharvest and storage.

Food traceability as an integral part of logistics management in food and agricultural supply chain
- 2013
-
In: Food Control. - : Elsevier BV. - 0956-7135 .- 1873-7129. ; 33, s. 32-48
-
Journal article (peer-reviewed)abstract
- The contemporary food supply chain (FSC) should adequately provide information that consumers and other concerned bodies need to know such as variety of the food attributes, country of origin, animal welfare, and genetic engineering related issues. For this, effective food traceability system (FTS) is important. The objective of this study was to conduct a comprehensive literature review on food traceability issues. About 74 studies, mainly focusing on food traceability issues and published during 2000–2013, were reviewed. Based on the review results, the definition, driving forces, barriers in developing and implementing FTSs, benefits, traceability technologies, improvements, and performances of FTSs have been identified and discussed. Considering FTS as an integral part of logistics management, new conceptual definition of FTS has been provided. This review has pointed out that the issue of developing effective and full chain FTS is quite complex in nature as it requires a deeper understanding of real processes from different perspectives such as economic, legal, technological, and social issues. Therefore, future researches (recommended here) on traceability should focus on: integration of traceability activities with food logistics activities; technological aspects of FTSs; the linkage between traceability system and food production units; standardization of data capturing and information exchange; awareness creation strategies; continuity of information flow and effective communication of traceability information to consumers and other stakeholders; the linkage between different drivers of FTS; improvement strategies of FTS; and development of performance evaluation frameworks for FTSs.

Electronic nose and Alicyclobacillus spp. spoilage of fruit juices: An emerging diagnostic tool
- 2010
-
In: Food Control. - : Elsevier BV. - 0956-7135 .- 1873-7129. ; 21:10, s. 1374-1382
-
Journal article (peer-reviewed)abstract
- The application of an electronic nose equipped with a Metal Oxide Semiconductor sensor array for the detection of Alicyclobacillus acidoterrestris and A. acidocaldarius artificially inoculated in peach, orange and apple fruit juices is described in this study. Overall the system was able to detect the presence of Alicyclobacillus spp. in all the tested fruit juices at 24 h from inoculation. The electronic nose could detect bacterial concentration as low as <10(2) colony forming unit/ml and it was also able to classify bacterial contamination independently of the Alicyclobacillus species. The gas chromatography-mass spectrometry characterization of the volatile profile of orange juices confirmed the existence of quantitatively different patterns between contaminated and uncontaminated samples.

Raw milk hygiene at farms, processing units and local markets in Burkina Faso
- 2010
-
In: Food Control. - : Elsevier BV. - 0956-7135 .- 1873-7129. ; 21, s. 1070-1074
-
Journal article (peer-reviewed)abstract
- The aim of this study was to investigate raw milk hygiene and composition along the dairy chain in Burkina Faso. Milk samples were taken during the rainy and dry seasons from individual cows, farm tanks, milk collectors' churns, dairy processing unit tanks and at local markets. The results showed lower total bacteria count (10-10(4) cfu/ml) in individual cow milk than later in the dairy chain. The total bacteria count in farm tank milk was 10(6) cfu/ml and 10(7) cfu/ml in tank milk at dairy processing units, in milk collectors' churns and in market buckets. Somatic cell count (100,000-150,000 cells/ml) did not show significant variation between individual cow milk and in the rest of the chain. Higher pH and lower milk fat and lactose contents were found in market bucket milk than in farm and processing unit tank milks. It was concluded that milk from the cow is of good hygienic quality, but milk is often contaminated after milking, and the hygienic quality is very low when it reaches the consumers. Also, milk sold at local markets had low fat and lactose contents and high pH during the rainy season, indicating that the milk may have been diluted, which may further increase the hazards for human health.

Antimicrobial activity of alginate/clay nanocomposite films enriched with essential oils against three common foodborne pathogens
- 2014
-
In: Food Control. - : Elsevier BV. - 0956-7135. ; 36:1, s. 1-7
-
Journal article (peer-reviewed)abstract
- The overall objective of this study was to develop antimicrobial nanocomposite films to control the growth of foodborne pathogens. In the first step, the antibacterial effects of clove, coriander, caraway, marjoram, cinnamon, and cumin essential oils were studied against three important food pathogens, Escherichia coli, Staphylococcus aureus, and Listeria monocytogenes by application of agar diffusion assay. The intensity of antimicrobial efficacy was in the following order: marjoram > clove > cinnamon > coriander > caraway > cumin. In the next study, the three most potent essential oils were subsequently incorporated into alginate/clay nanocomposite films. The antibacterial effectiveness of the prepared films against E. coli, S. aureus, and L. monocytogenes was studied during 12 days. The antibacterial activity of the essential oils was maintained when incorporated into the nanocomposite film. The nature and amount of the essential oils play an important role in the film's antimicrobial activity. In all film matrices, marjoram showed the highest antimicrobial activity. Films with 1.5% marjoram decreased the numbers of L. monocytogenes, E. coli, and S. aureus populations with respect to the control up to 6.33, 4.52, and 5.80 log, respectively.
