"Acidified Calcium Sulfate"
Reduces Microbial Population and Maintain Quality of
Fresh-cut Cantaloupe & Litchie Fruit
Cantaloupe Study: Innovative treatments are needed to increase antimicrobial efficacy while maintaining quality of fresh- peroxyacetic acid (Tsunami), and combination of ACS and Tsunami for 10 min. Populations of aerobic However, none of the sanitizers had any significant effect on the fresh-cut samples prepared from the sanitization of whole cantaloupe with ACS had a similar efficacy as Sanova in reducing microbial Therefore, ACS is a potential surface sanitizer of whole fruit for preparing fresh-cut cantaloupes.

cantaloupes with acidified calcium sulfate (ACS) in comparison with three common sanitizers on
microbial population and quality of freshcut cantaloupes. Whole cantaloupes were submerged in water,
100 ppm chlorine, ACS (1.2% Safe2O-ACS50), 1000 ppm acidified sodium chlorite (Sanova), 80 ppm
bacteria, yeast and mold on the rind of whole cantaloupes weremeasured. Quality and microflora
population of the fresh-cut pieces prepared from the whole fruits were quantified during 14-day storage
at 4 C. Compared to water wash, none of the treatments had a consistent effect on bacterial population on
the surface of whole cantaloupe. Yeast and mold count on the whole cantaloupe was reduced by chlorine,
Tsunami and Sanova while ACS only reduced the count in one of the two trials.
surface pasteurized whole fruit. The aerobic bacterial population on the fresh-cut cantaloupe was
significantly reduced by ACS and Sanova pasteurization of whole fruit. The low population of bacterial
population on the fresh-cut fruit was maintained during the entire storage period. Other treatments had
no population. The combination of ACS and Tsunami did not provide any additional microbial reduction
compared to ACS or Tsunami alone. Color, texture, soluble solids content, pH, ascorbic acid and drip loss
were not consistently affected by any of the treatments. Samples treated with Tsunami deteriorated in
appearance and aroma after 7 and 14 days of storage in one of the trials. Our results suggest that

Maintaining quality of litchi fruit with acidified calcium sulfate. Journal of Agricultural and Food Chemistry. 58:8658-8666. Interpretive Summary: Two of the most serious problems affecting the postharvest quality of litchi fruit are decay and browning or loss of red color on the peel of the fruit. We found that treatment of litchi fruit with acidified calcium sulfate, a GRAS (Generally Recognized As Safe) compound, could inhibit the mold growth, prevent browning and retain red color of the peel. We also showed that this treatment did not have any adverse effect on the internal quality of the litchi fruit including soluble solids, sugar, and organic acid content. Information obtained in this study is of interest to other scientists and will be useful and beneficial to the litchi fruit industry and consumers. Technical Abstract: The effect of acidified calcium sulfate (ACS) on quality of litchi (Litchi chinensis Sonn. cv `Brewster") fruit after harvest was evaluated. ACS at 1.25% or higher concentrations significantly inhibited the activities of polyphenoloxidase and peroxidase in pericarp during storage at both 5 and 10 ºC. These treatments also effectively prevented browning and retained red color of the outer shell of the fruit. Total phenolic and total anthocyanin content in pericarp were increased by the ACS treatments at the dose dependent manner. The radical scavenging activities for ROO", DPPH*, "OH and O2"- were also enhanced by ACS, particularly by 2.5 and 5% concentrations. The activities of several antioxidant enzymes and enzymes of ascorbate-glutathione cycle including catalase, ascorbate peroxidase, glutathione peroxidase, glutathione reductase, dehydroascorbate reductase, and monodehydroascorbate reductase gradually declined during storage. However, ACS enhanced the activities of these enzymes especially at the beginning of the storage. Samples treated with ACS generally had higher flavonoid levels then the control. The two major flavonoids, cyanidin-3-rutinoside and cyaniding-3-glucoside, were found to be significantly increased by 2.5 and 5.0% ACS at both 5 and 10 ºC. No differences were detected among various treatments in soluble solids content, sugar, and organic acid levels in the pulp of litchi fruit, indicating that the internal quality of the fruit was not affected by the ACS treatment. |
Food microbiology has shown that good food hygiene and food safe temperatures along with use of ACS Technology Inc. SafepHix brand Acidic Calcium Sulfate, ACS 100, will control Salmonella Listeria, diseases in food and other hazards in food. This has proven beneficial for controlling Salmonella and Campylobacter with use of ACS Technology SafepHix brand Acidic Calcium Sulfate, Freshphix or pHesh-phix 100, for antimicrobial effectiveness vegetable wash and vegetable cleaner on whole vegetables.
Food industry leaders implement a food protection program using ACS Technology SafepHix brand ACS 100, acidic calcium sulfate, to insure quality control of food and any disease of bacteria. Safety in the food industry is paramount for food quality management and quality control of meat and poultry. Preventing bacterial food contamination, bacteria food poisoning or foodborne illnesses, such a campylobacter, Listeria m or salmonella food illness is essential food safety in food industry.
The ACS Technology's SAFE-phix® brand Family of Solutions is a unique broad based proprietary technology with a number of features that benefit a wide variety of industries. pH adjustment chemicals can be used with ACS Technology SafepHix brand Acidic Calcium Sulfate, ACS 100, pHixr or pHixr 100 for ORP and pH adjustment, and in automatic pH adjuster, such as electronic monitoring pH indicator and dispensing equipment for adjusting pH in water, primarily to lower pH in water. Due to organic matter (poultry) entering the poultry water or chicken water pushing the pH up, adding Acidic Calcium Sulfate, ACS 100, pHixr or pHixr 100 will increase the ORP of the poultry water processing in poultry processing plants, optimizing the orp-oxidation reduction potential. Food processing plants can also benefit in other applications when utilizing Acidic Calcium Sulfate, ACS 100, pHixr or pHixr 100 in their poultry processing water. The ACS Technology SafepHix brand Acidic Calcium Sulfate, ACS 100, pHixr or pHixr 100 will begin controlling bacterial in floor drains with the food processing plants, as well as throughout the food processing equipment during the food process. Within the food industry and the making of processed foods, food safety and Listeria salmonella prevention is of a particular concern. New food processing technology and food processing methods, such as implementing Ready To Eat RTE 01 or rt-01, aka Acidic Calcium Sulfate, ACS 100, pHixr or pHixr 100 on or in the food processes or in lieu of any irradiated food is excellent for listeria salmonella prevention.
