Embodiment 1

[0061] Embodiment 1: the making of composite antistaling agent

[0062] (1) Add 1.5g sodium alginate to 500mL water to prepare a sodium alginate solution, add 3.8g gelatin, 3.8g carrageenan and 3.8g xanthan gum to the sodium alginate solution and mix to form a sol;

[0063] (2) Add 20g Chrysanthemum chrysanthemum flavonoids extract and 20g Mountain Silver Flower polyphenol extract to 500mL water to make a mixed extract, then add 0.4g radish lysozyme and 0.4g barley lysozyme to continue mixing to form a mixed solution ;

[0064] (3) The above mixed solution was added dropwise to the sol in step (1) at a speed of 0.8 mL / s under the action of mechanical stirring and mixed to obtain the composite preservative 1.

Embodiment 2

[0065] Embodiment 2: the making of composite antistaling agent

[0066] (1) Add 1.5g sodium alginate to 500mL water to prepare a sodium alginate solution, add 3.8g gelatin, 3.8g carrageenan and 3.8g xanthan gum to the sodium alginate solution and mix to form a sol;

[0067] (2) Add 15g of Chrysanthemum chrysanthemum flavonoids extract and 25g of Alba japonica polyphenols extract to 500mL of water to make a mixed extract, then add 0.4g of radish lysozyme and 0.4g of barley lysozyme to continue mixing to form a mixed solution ;

[0068] (3) Add the above-mentioned mixed solution dropwise to the sol in step (1) at a rate of 0.8 mL / s under mechanical stirring, and mix to obtain the composite preservative 2.

Embodiment 3

[0069] Embodiment 3: the making of composite antistaling agent

[0070] (1) Add 1.5g sodium alginate to 500mL water to prepare a sodium alginate solution, add 3.8g gelatin, 3.8g carrageenan and 3.8g xanthan gum to the sodium alginate solution and mix to form a sol;

[0071] (2) Add 25g of Chrysanthemum chrysanthemum flavonoids extract and 15g of Alba japonica polyphenols extract to 500mL water to make a mixed extract, then add 0.4g of radish lysozyme and 0.4g of barley lysozyme to continue mixing to form a mixed solution ;

[0072] (3) The above mixed solution was added dropwise to the sol in step (1) at a speed of 0.8mL / s under the action of mechanical stirring, and mixed to obtain the composite preservative 3.

Abstract

The invention discloses a preparation method and application of a plant source complex preservative. Each liter of water contains, by weight, 0.5 to 2.5g of sodium alginate, 0.2 to 7.5g of gelatin, 0.2 to 7.5g of carrageenan, 0.2 to 7.5g of xanthan gum, 0.1 to 1.5g of lysozyme, 15 to 25g of crowndaisy chrysanthemum flavone extract and 15 to 25g of lonicerae flos polyphenol extract. The crowndaisy chrysanthemum flavone extract and the lonicerae flos polyphenol extract with a synergistic effect form a substance capable of interdicting cell schizogamy under the action of lysozyme, thus obtaining the complex preservative good in preservation effect with the natural extracts as the main materials.

Description

technical field [0001] The invention belongs to the field of antiseptic and fresh-keeping of food, and in particular relates to a preparation method and application of a plant-derived composite fresh-keeping agent. Background technique [0002] Food preservation is an eternal subject, and various preservatives emerge in endlessly. Food preservatives can be divided into two categories, namely chemical synthesis and natural preservatives. For a long time, people have mainly used chemically synthesized preservatives to preserve the freshness of stored fruits and vegetables. Although chemically synthesized preservatives have better fresh-keeping and antiseptic effects, many chemically synthesized substances have certain toxic and side effects on human health. Therefore, people began to turn their attention to natural preservatives, and natural plant extracts became the focus of people's research. Contents of the invention [0003] The object of the present invention is to p...
