Fresh-Cut Vegetables

Combinations of detaint agents and Modified atmosphere case for shelf-life extension of minimally lissom vegetables Introduction Minimally urbane or fresh cut vegetables be highly vulnerable to complaint organism because of damaged and heart-to-heart tissues and lack of protective trim (Watada & Qi, 1999). Thus, the shelf life pitiful normal conditions is very limited. The output signal chain of minimally neat vegetables consists of simple unit operations including washout, drying, chopping, shredding, etc. The washing aspiration is the only step which the microbic contamination can be reduced by the incomplete removal of micro-organisms and by removing the fall back cell contents released during slice or shredding that help meet microbial growth (De Roever, 1999). Although the rear of washing results in microbial reducings of 0.1-1.0 log10cfu/g, decontamination agents ar frequently added to the washing piss to increase the decontamination readiness with the depend to assure safety and prolong shelf-life of fresh-cut make water (Beuchat, 1998). The contamination agent which has been wildly used in the fresh-cut attention is chlorine payable to its efficiency in decontamination and inexpensive.

However, thither is a trend in eliminating chlorine from the disinfection process because of the concerns active the environmental and health risks associated with the governance of carcinogenic halogenated disinfection by products (Olmez and Kretzschmar, 2009). Therefore, early(a) more innovative decontamination agents much(prenominal) as fumaric acid, calcium oxide, ethyl radical alcoholic beverage and electrolyzed oxidizing water have been studied for their return in the fresh-cut puzzle industry. Fumaric acid is a food-grade acidulant with laborious bactericidal bodily do (Comes and Beelman, 2002), and it has been used as an disinfectant against pathogenic bacteria in fresh-cut lettuce (Kondo, Murata and Isshiki, 2006). Treatment with 50 mM of fumaric acid for 10 min caused a 2-log reduction in...If you want to get a full essay, order it on our website: Ordercustompaper.com
