In statistics, several tools are used to interpret the data. Measures of central tendency represent the characteristics of the data, such as mean, median, and mode. Additionally, measures of variance like standard deviation and range are used to find the spread of data from the mean. Relative standing measures the distance between data locations. Commonly used measures of relative standings are percentile, z score, and quartiles.
Percentiles are a type of fractile that partition data into...

Data are individual items of information obtained from a population or sample. Data may be classified as qualitative (categorical), quantitative continuous, or quantitative discrete. Because it is not practical to measure the entire population in a study, researchers use samples to represent the population. A random sample is a representative group from the population chosen by using a method that gives each individual in the population an equal chance of being included in the sample. Random...

Area of Science:

  • Food Science
  • Microbiology
  • Toxicology

Background:

  • Nitrite sparing agents are sought for cured meat products.
  • Sodium hypophosphite (SHP) has historical uses and emerging antimicrobial research.
  • SHP is Generally Recognized As Safe (GRAS) for food applications.

Purpose of the Study:

  • To review the chemistry, history, toxicology, and regulatory status of SHP.
  • To explore the potential applications of SHP as a food ingredient.
  • To summarize the antimicrobial properties of SHP.

Main Methods:

  • Literature review of scientific publications.
  • Analysis of historical data on hypophosphites.
  • Examination of regulatory documents and GRAS status.

Main Results:

  • SHP exhibits potential antimicrobial and antibotulinal properties.
  • SHP has a favorable regulatory status (GRAS).
  • SHP has diverse applications beyond its historical use.

Conclusions:

  • Sodium hypophosphite is a viable candidate as an antimicrobial food ingredient.
  • Further research into SHP applications in cured meats is warranted.
  • SHP's safety profile supports its consideration in food preservation.
