Embodiment 1－5

[0062]1000 ml of the solutions described in Table 1 below were prepared in a beaker at 80°C and placed in an immersion tester, stirred with a stirring bar at 30 rpm. Put the pure milk stained sample prepared above into the beaker to be tested at 80°C for 15 minutes. The samples were then removed and placed overnight in a humidity cabinet at 30°C and 60% relative humidity. Then, the sample is weighed. Four samples were used for each solution tested.

[0063] The soil removal rate of the soiled samples was obtained gravimetrically and calculated as follows:

[0064] Dirt removal rate%=(the weight of the stained sample before cleaning, the weight of the stained sample after cleaning) / (the weight of the stained sample before cleaning, the weight of the sample before staining)x100

[0065] The soil release rate for each solution tested is reported as the average of the soil release rates for the four samples. The results are shown in Table 1.

Embodiment 6-9

[0072] 1000 ml of the solutions described in Table 2 below were prepared in a beaker at 80°C and placed in an immersion tester, stirred with a stirring bar at 30 rpm. Put the pure milk stained sample prepared above into the beaker to be tested at 80°C for 10 minutes. The samples were then removed and placed overnight in a humidity cabinet at 30°C and 60% relative humidity. Then, the sample is weighed. Three samples were used for each solution tested.

[0073] The soil release rate for each solution tested is reported as the average of the soil release rates for the three samples. The results are shown in Table 2.

Embodiment 10-13

[0077] 1000 ml of the solutions described in Table 3 below were prepared in a beaker at 80°C and placed in an immersion tester, stirred with a stirring bar at 30 rpm. Put the pure milk stained sample prepared above into the beaker to be tested at 80°C for 10 minutes. The samples were then removed and placed overnight in a humidity cabinet at 30°C and 60% relative humidity. Then, the sample is weighed. Seven samples were used for each solution tested.

[0078] The soil release rate for each solution tested is reported as the average of the soil release rates for the seven samples. The results are shown in Table 3.

Abstract

The invention discloses a clean in place (CIP) cleaning composition for milk product, food and beverage equipment, and a CIP method using the cleaning composition, wherein the cleaning composition contains i) about 0.1-4.0 wt% of at least an alkaline source, ii) about 0.01-5.0 wt% of at least a salt selected from an inorganic sulfate, a sulfite and an organic sulfate, and iii) an aqueous medium.

Description

field of invention [0001] The present invention relates to sulphate / sulphite containing alkaline cleaning compositions useful for cleaning in place (CIP) of dairy, food and beverage installations, and to CIP methods using said compositions. The cleaning composition and CIP method of the present invention are capable of effectively removing protein, especially denatured protein soils resulting from Ultra-Heat-Treatment (UHT). Background technique [0002] Regular cleaning in the dairy, food and beverage industries is an essential practice for product quality and public health. Residue left on equipment surfaces can promote the growth of microorganisms. Protecting consumers from potential health hazards associated with pathogens or toxins and maintaining product quality requires routine removal of residues from surfaces. [0003] Clean-in-place technologies use a combination of chemical and mechanical action to clean the interior of a system without requiring time-consuming ...
