Description

Technical Field

[0001] The present invention relates to a particulate composition comprising:

[0002] · an organic acid salt selected from sodium acetate, potassium acetate, sodium lactate, potassium lactate, calcium lactate, sodium propionate, potassium propionate, and combinations thereof;

[0003] · a diacetate component selected from sodium diacetate, potassium diacetate, and combinations thereof; and

[0004] · disodium diphosphate.

[0005] The particulate composition of the present invention can be suitably used as a food preservative, for example, in meat products. Background Art

[0006] Meat preservation is a severe challenge because contaminated meat can pose health threats such as Listeria, Salmonella, and E. coli. These well-known pathogenic bacteria can multiply in unprotected meat, leading to a series of fatal diseases.

[0007] In addition to ensuring the safe consumption of individual consumers, meat preservation and protection are also an important part of the global food supply chain, which faces the challenge of feeding a global population that will increase from the current 7 billion to 9 billion by the end of the 2030s. Statistically, more than one-third of all food produced today is ultimately classified as "loss" or "waste," causing an annual loss of approximately $940 billion to the global economy and accounting for 8% - 10% of global greenhouse gas emissions. Since meat is the category with the greatest economic and environmental impact in global food waste, the preservation and protection of meat are issues of concern to the whole society.

[0008] Organic acids have very valuable antibacterial functions and are widely used by meat processors. These organic acids are usually applied in the form of sodium salts, potassium salts, or calcium salts. Examples of such organic acid salts include sodium acetate, potassium acetate, sodium lactate, potassium lactate, calcium lactate, and sodium diacetate.

[0010] 18.5% to 26.0% by weight of potassium lactate;

[0011] 18.5% to 26.0% by weight of potassium acetate; and

[0012] 10.0% to 17.0% by weight of sodium diacetate.

[0106] 3Composition: 34% sodium acetate, 34% sodium lactate, 30% sodium diacetate, 2% silica (from Corbion)

[0107] The raw materials were processed into an emulsion using a Robot Coupe R.V.10 bowl cutter. The emulsion was placed in a vacuum shrink bag and cooked in a water bath at 85 °C for 1 hour 30 minutes. The cooked emulsion was quickly cooled in ice water and stored at 4 °C for 56 days, during which the pH of the ham was monitored. The results are shown in Table 4.

[0108] Table 4.

[0109]

[0110] A panel of experts evaluated the ham. The panelists scored the sensory attributes such as saltiness, sweetness, sourness, bitterness, and meat texture on a scale of 0 - 10 (the higher the attribute intensity, the higher the score). The panelists were also asked to score the quality of each ham on a scale of 0 - 10 (0 = unacceptable, 10 = excellent). The results of the panel evaluation are shown in Table 5.

[0113] The microbiological stability test of the ham was as follows:

[0114] Each ham was cut into small pieces and then inoculated with chopped commercial ham at a dose of 10% by weight. The mixture was thoroughly mixed in a sterile food processor and then divided into 20 g portions, placed in lateral filter bags and vacuum sealed for microbiological testing. A small amount of the blended mixture was vacuum packaged in a stomacher bag for pH measurement. The vacuum-sealed packages of samples were divided into 2 groups and incubated at 4 °C and 10 °C respectively.

[0115] Every 7 days after inoculation, one package was randomly selected from each group (4 °C and 10 °C) for microbiological measurement. The 20 g vacuum-packaged samples were combined with physiological saline peptone water in a 1:1 ratio and thoroughly mixed. The mixture was serially diluted and the total viable aerobic count (TVAC) was examined by spiral plating on TSA. The agar plates were incubated at 30 °C for 48 hours. During storage at a specific temperature, the microbial counts were expressed as log10 cfu / g.

[0116] Using the total viable aerobic count (TVAC) of log 6 as the standard limit of spoilage, the results of the microbiological tests are summarized in Table 6 (TTL is the time to reach log 6.0).
