Embodiment 1

[0024] Example 1 Synergistic effect of rosmarinic acid extract and carnosic acid extract on antioxidant oil

[0025] Test method: adopt Schaal oven method, take 50g peanut oil, put into beaker, add mass concentration and be 0.02% carnosic acid extract (ECA), 0.02% rosmarinic acid extract (ERA), mass concentration is 0.01% ECA+ The mass concentration is 0.01% EA, 0.02% vitamin C, butylated hydroxyanisole (BHA), 2,6-di-tert-butyl-p-cresol (BHT), propyl gallate (PG), mix well, put into 60 ℃ in an incubator, stir once every 24h and change position, take samples to measure peroxide value (POV) according to GB / T5009.37-1996. See figure 1 , figure 1 It is a map of synergistic antioxidant effect of carnosic acid extract and rosmarinic acid extract on oil. The research results show that the combined use of carnosic acid extract and rosmarinic acid extract has significantly better antioxidant effect than the same High-quality single extract, and its antioxidant effect is similar to t...

Embodiment 2

[0026] Example 2 The antiseptic effect of the composition on fresh meat

[0027] Ⅰ. Antiseptic effect of individual extract components

[0028] Test method: Take 30% carnosic acid extract and 25% rosmarinic acid extract at 1:100, 1:50, 1:20, add water to dissolve or grind into a dispersible uniform suspension, take fresh pork slices and place in Immerse in the extract water for 10 seconds, 3 slices per portion, expose the dipped meat slices to the air at an ambient temperature of 15-25°C, observe the color, smell and meat resilience of the meat slices every 8 hours.

[0029] Table 1 Antiseptic effect of carnosic acid extract and rosmarinic acid extract on fresh pork

[0030]

[0031]

[0032] The test results are shown in Table 1, which shows that the two kinds of rosemary extracts can significantly slow down the deterioration process of fresh meat.

[0033] Ⅱ. Individual and synergistic antiseptic effects of carnosic acid extract and rosmarinic acid extract on chilled...

Embodiment 3

[0044] Example 3 Research on the Preservation Effect of the Composition on Juicy Peach

[0045] Test method: Dissolve chitosan in 2% citric acid solution, and prepare a solution with a chitosan concentration of 0.5%, which is fresh-keeping solution 1 (chitosan solution, as a film-forming agent, also has a certain fresh-keeping effect) ;Take 30% carnosic acid extract and 25% rosmarinic acid extract and mix according to 1:1, add the above preservative solution 1 and grind evenly, then continue to add preservative solution 1 to make a mixture containing 2% of the total extract, which is fresh Liquid 2. Take commercially available peaches, soak them in the preservative solution for 30 seconds, and dry them fully to form a uniform transparent film on the surface of the fruits. Place them in a carton at room temperature, and measure the water loss rate of the peaches every 2 days. and soluble solids, observe the peaches to indicate whether there are rot spots, and calculate the spo...

Abstract

The invention relates to a rosemary extract composition. The rosemary extract composition comprises a carnosic acid extract and a rosmarinic acid extract, wherein the weight ratio of the carnosic acid extract to the rosmarinic acid extract is (4 to 6)-(8 to 2). The rosemary extract composition can be used as a preservative; furthermore, a synergistic interaction effect is generated between the components in a certain ratio range, so that the effect of the rosemary extract composition is superior to that of the carnosic acid extract or the rosmarinic acid extract.

Description

technical field [0001] The invention relates to a composition which can be used for food preservation and preservation. The composition is extracted from rosemary leaves, and specifically relates to the composition and application of the composition.
