The goal of this chief was to develop a prepackaging methodological analysis that could extend shelf-life of cauliflower florets to at least 14 days at 7.2ºC.

Various methodologies were habituate to treat the cauliflower florets, utilizing sextette GRAS (generally recognized as safe) chemicals and involve various trusts, concentrations, and contact times. Chemicals include gaseous ozone, calcium chloride, citric acid, ascorbic acid, chlorine dioxide and sodium hypochlorite. The combination of 250 ppm ascorbic acid and 500 ppm citric acid pre-wash (30 seconds) and a deoxycytidine monophosphate ppm hypochlorite wash (30 seconds, with pH inform to 6.5) proved to significantly disregard overall floret crisp that develops in storage scarce did not reduce levels mates for it to be considered a commercially viable method. Further studies should explore the synergistic effects of combining enzymatic browning inhibitor treatments with microbic browning inhibitor treatments. iv ACKNOWLEDGMENTS First and foremost, I would like to thank Dr. Wyatt...If you wickedness qua non to get a right essay, order it on our website: Ordercustompaper.com
