Improvement of the Waste Refrigerator Pre-processing Line in Metropolitan Recycling Center using Simulation

A series of seed-processing machines were used to evaluate seed quality improvement in paddy during the Kharif season 2013-14. The processing machines proved an efficient tool in producing quality seeds. The consistent and higher seed quality (germination 91.67% and physical purity 99.83%) could be achieved by efficient use of processing machines. The product and separate (reject) from individual machines were analysed to evaluate machine efficiency in separating the seed components as well as impurities from the harvested lot. The air-screen machines were found effective in removing dead seeds, whereas specific gravity separator removed abnormal seeds significantly. Gradual increase in seed quality was recorded with decrease in recovery in the processing line. Seed loss in reject port was always associated with handling of seed lots by each machine and observed only 1.30%. Specific gravity separator was found essential for the seed lot of medium-term storage or for the buffer stocking.

Fresh Cut

Cross-contamination of fresh-cut leafy greens with residual Escherichia coli O157:H7–contaminated product during commercial processing was likely a contributing factor in several recent multistate outbreaks. Consequently, radicchio was used as a visual marker to track the spread of the contaminated product to iceberg lettuce in a pilot-scale processing line that included a commercial shredder, step conveyor, flume tank, shaker table, and centrifugal dryer. Uninoculated iceberg lettuce (45 kg) was processed, followed by 9.1 kg of radicchio (dip inoculated to contain a four-strain, green fluorescent protein–labeled nontoxigenic E. coli O157:H7 cocktail at 106 CFU/g) and 907 kg (2,000 lb) of uninoculated iceberg lettuce. After collecting the lettuce and radicchio in about 40 bags (~22.7 kg per bag) along with water and equipment surface samples, all visible shreds of radicchio were retrieved from the bags of shredded product, the equipment, and the floor. E. coli O157:H7 populations were quantified in the lettuce, water, and equipment samples by direct plating with or without prior membrane filtration on Trypticase soy agar containing 0.6% yeast extract and 100 ppm of ampicillin. Based on triplicate experiments, the weight of radicchio in the shredded lettuce averaged 614.9 g (93.6%), 6.9 g (1.3%), 5.0 g (0.8%), and 2.8 g (0.5%) for bags 1 to 10, 11 to 20, 21 to 30, and 31 to 40, respectively, with mean E. coli O157:H7 populations of 1.7, 1.2, 1.1, and 1.1 log CFU/g in radicchio-free lettuce. After processing, more radicchio remained on the conveyor (9.8 g; P < 0.05), compared with the shredder (8.3 g), flume tank (3.5 g), and shaker table (0.1 g), with similar E. coli O157:H7 populations (P > 0.05) recovered from all equipment surfaces after processing. These findings clearly demonstrate both the potential for the continuous spread of contaminated lettuce to multiple batches of product during processing and the need for improved equipment designs that minimize the buildup of residual product during processing.

PurposeThe purpose of this paper is to evaluate the possible microbiological contamination in terms of total counts and representative microbial groups found in the hazelnuts as well as in work areas and on the working surfaces of a hazelnut processing plant.Design/methodology/approachSome microbiological parameters related to the manufacturing process (e.g. aerobic colony count yeast and fungi) were evaluated. Indoor air samples were tested in order to evaluate the possible contamination of fungal strains (i.e. mycotoxin producing fungi).FindingsThe results showed that the highest values (>of 500 CFU/m3) for bacteria and fungi were only observed in the shelling and sorting areas. Some species such as Aspergillus and Penicillium (potential mycotoxin-producers) as well as some noxious colonies ofAspergillus fumigatuswere detected along the processing line. No occurrence of aflatoxins was observed in the finished product. Microbial loads obtained through surface analyses were in accordance to the reference data.Originality/valueThe aim of this study was to monitor and improve the procedures currently used in a hazelnut processing plant.

Field Production

‘Nam Dok Mai’ mango is a luxury commercial fruit in Thailand, but post-harvest diseases infecting the ripe fruit is a major problem affecting marketability. The objective of the present study was to map the supply chain of ‘Nam Dok Mai’ mangoes exported to Japan and analyze the critical points of post-harvest disease infection caused mainly by Colletotrichum gloeosporioides. Risk points of the post-harvest diseases were found by examining the material and information flows from processes ranging from field production to post-harvest handling, and these were obtained from mango growers and an exporter. The findings of interviews with mango growers and observations of the mangoes in field production were that the first point of risk was cultivar selection, while branch pruning and fruit bagging were further important processes causing post-harvest fruit decay. On the other hand, it was found that post-harvest handling was significant in decreasing anthracnose disease infection; this was seen at the step of dipping the fruit in 50 °C hot water for 3 min at the processing line.
