Problems solved by technology

Preservatives can effectively inhibit the growth and reproduction of microorganisms in food and prolong the storage period of food. They play an irreplaceable role in processed foods, but excessive intake of preservatives will have a certain toxic effect on the human body. The application of preservatives It has become an extremely sensitive issue for consumers, and the cost of plant preservation is very expensive. Mix plant extracts and a small amount of preservatives, and use their synergy to reduce the amount of preservatives added

Embodiment 1

[0022] A kind of plant extract compound liquid food preservative of the present embodiment comprises the following raw materials in parts by weight:

[0023] 20 parts of alkaloid extract, 15 parts of nisin, 1 part of dehydroacetic acid, 1 part of potassium sorbate, 15 parts of ethylenediaminetetraacetic acid di-sodium solution.

[0024] The preparation method of the extract in this example is as follows: crush lotus leaves and bamboo leaves, pass through a 200-mesh sieve, then use 90% ethanol as the extractant, extract at 90°C, centrifuge and filter for 2 hours each time, to obtain the extract liquid.

[0025] In this embodiment, at 90° C., the extraction was carried out once each at a ratio of solid to liquid of 1:15 and 1:10.

[0026] The preparation method of the anti-corrosion and fresh-keeping agent of this embodiment is as follows: first put dehydroacetic acid into the alkaloid extract at 100°C and stir for 20 minutes, then drop the temperature to 85°C, then add disodiu...

Embodiment 2

[0028] A kind of plant extract compound liquid food preservative of the present embodiment comprises the following raw materials in parts by weight:

[0029] 40 parts of alkaloid extract, 30 parts of nisin, 5 parts of dehydroacetic acid, 5 parts of potassium sorbate, 20 parts of ethylenediaminetetraacetic acid di-sodium solution.

[0030] The preparation method of the extract in this example is as follows: crush lotus leaves and bamboo leaves, pass through a 200-mesh sieve, then use 90% ethanol as the extractant, extract at 90°C, centrifuge and filter for 2 hours each time, to obtain the extract liquid.

[0031] In the present embodiment, at 90° C., the extraction was carried out twice at a solid-liquid ratio of 1:15 and 1:10 respectively.

[0032] The preparation method of the anti-corrosion and fresh-keeping agent of this embodiment is as follows: first put dehydroacetic acid into the alkaloid extract at 100°C and stir for 20 minutes, then drop the temperature to 85°C, then...

Embodiment 3

[0034] A kind of plant extract compound liquid food preservative of the present embodiment comprises the following raw materials in parts by weight:

[0035] 30 parts of alkaloid extract, 22.5 parts of nisin, 3 parts of dehydroacetic acid, 3 parts of potassium sorbate, 22.5 parts of ethylenediaminetetraacetic acid di-sodium solution.

[0036] The preparation method of the extract in this example is as follows: crush lotus leaves and bamboo leaves, pass through a 200-mesh sieve, then use 90% ethanol as the extractant, extract at 90°C, centrifuge and filter for 2 hours each time, to obtain the extract liquid.

[0037] In the present embodiment, at 90° C., the extraction was carried out twice at a solid-liquid ratio of 1:15 and 1:10 respectively.

[0038] The preparation method of the antiseptic and antistaling agent of this embodiment is as follows: firstly put dehydroacetic acid into the extraction glycoside solution at 100°C and pH > 9 and stir for 20 minutes, then drop the t...

Abstract

The invention discloses a plant extraction compound liquid food preservative and fresh-keeping agent, which comprises the following raw materials in parts by weight: 20-40 parts of alkaloid extraction liquid, 15-30 parts of nisin, 1-5 parts of dehydroacetic acid, 1-5 parts of potassium sorbate and 15-20 parts of ethylene diamine tetraacetic acid. The preservative and fresh-keeping agent is compounded by the extraction liquid, the nisin, the dehydroacetic acid, the potassium sorbate and the ethylene diamine tetraacetic acid. The alkaloid extraction liquid is prepared from folium nelumbinis and Phyllostachys nigra (Lodd. exLindl.) Munro var.henonis (Mitf.) Stapf et Rendle leaf extraction agents; after compounding is carried out, all ingredients jointly act to generate a synergistic effect, an anti-bacteria effect is obvious, and broad-spectrum antibacterial capacity is enhanced. The antibacterial activity of the plant extraction compound liquid food preservative and fresh-keeping agent is not affected by pH change, the plant extraction compound liquid food preservative and fresh-keeping agent is safe and nontoxic, has wide applicability, stable performance and low cost and can be used in a food to lower the adding amount of preservatives in the food, and meanwhile, an anticipated anti-corrosion effect can be achieved.

Description

technical field [0001] The invention relates to the technical field of antiseptic and fresh-keeping of food, in particular to a plant-extracted compound liquid food anti-corrosion and fresh-keeping agent. Background technique [0002] Preservatives are used to prevent food from deteriorating due to microbial reproduction during storage and circulation, or due to poor storage and sales conditions, and the internal quality of food deteriorates. It is used in food to improve the shelf life and prolong the edible value additives. With the improvement of people's living standards, the types of food supply are becoming more and more abundant, but the food safety problems that follow are also emerging in an endless stream. Preservatives can effectively inhibit the growth and reproduction of microorganisms in food and prolong the storage period of food. They play an irreplaceable role in processed foods, but excessive intake of preservatives will have a certain toxic effect on the ...
