Embodiment 1

[0021] Grind galangal (dried product) and pass through a 60-mesh sieve. Add galangal with 12% water and cook in a certain amount of drinking water. During the cooking process, make up the amount of water lost due to volatilization. After boiling for one hour, filter and use the filtrate for later use. Add 0.3% potassium sorbate, 0.2% sodium dehydroacetate, 0.5% browning inhibitor citric acid, 0.5% water retaining agent xanthan gum and 0.5% antioxidant sodium erythorbate to the filtrate to obtain a synergistic preservation solution. Pack the quantitative synergistic preservative solution in a plastic bottle with a spray function. Every 100 Kg of fresh day lily is sprayed with 2-3 Kg of synergistic fresh-keeping solution. The spray must be uniform. After spraying, quickly put the day lily into a PVC plastic bag with a weight of 10Kg, seal it, and store it in a cool place.

Embodiment 2

[0023] Grind the licorice (dried product) and pass through a 60-mesh sieve. Add licorice with 12% water and boil it in a certain amount of drinking water. During the cooking process, make up the amount of water lost due to volatilization. After boiling for one hour, filter it and use the filtrate for later use. Add 0.3% preservative potassium sorbate and 0.2% sodium dehydroacetate, 0.5% browning inhibitor citric acid, 0.5% water-retaining agent xanthan gum and 0.5% antioxidant sodium erythorbate to the filtrate to obtain a synergistic preservation solution. Pack the quantitative synergistic preservative solution in a plastic bottle with a spray function. Every 100 Kg of fresh day lily is sprayed with 2-3 Kg of synergistic fresh-keeping solution. The spray must be uniform. After spraying, quickly put the day lily into a PVC plastic bag with a weight of 10Kg, seal it, and store it in a cool place.

Embodiment 3

[0025] Cloves (dry product) are crushed and passed through a 60-mesh sieve. Add cloves with 12% water and cook in a certain amount of drinking water. During the cooking process, make up the amount of water lost due to volatilization. After cooking for one hour, filter and use the filtrate for later use. Add 0.3% preservative potassium sorbate and 0.2% sodium dehydroacetate, 0.5% browning inhibitor citric acid, 0.5% water-retaining agent xanthan gum and 0.5% antioxidant sodium erythorbate to the filtrate to obtain a synergistic preservation solution. Pack the quantitative synergistic preservative solution in a plastic bottle with a spray function. Every 100 Kg of fresh day lily is sprayed with 2-3 Kg of collaborative fresh-keeping solution. The spray must be uniform. After spraying, quickly put the day lily into a PVC plastic bag with 10Kg as the weight unit and seal it. Store in a cool place.

Abstract

The invention relates to a day lily refreshing technology under the normal temperature condition. The technology comprises a synergy refreshing solution and a refreshing method. The synergy refreshing solution consists of 6-12% of spice or Chinese herbal medicine which is both edible and usable, 0.1-0.5% of preservative, 0.5-1.0% of browning inhibitor, 0.5-0.8% of water-retaining agent and 0.5-1.0% of antioxidant. Every 100Kg of fresh day lilies are sprayed with the 2-3Kg of synergy refreshing solution, and have to be uniformly sprayed, and the day lilies are quickly put into a polyvinyl chloride (PVC) plastic bag at the weight unit of 10Kg to be sealed after the spraying, and are stored at the shade place. On the one hand, the refreshing method can prolong the shelf life of the fresh day lilies, so the commodity value of the fresh day lilies is improved, and the economic benefit is increased; and on the other hand, the problems that the day lilies cannot be timely dried and are decayed in overcast and rainy days are solved, and the economic loss of the day lilies is avoided.

Description

technical field [0001] The invention relates to a fresh-keeping method for day lily at room temperature, belonging to the technical field of food processing. Background technique [0002] day lily ( Hemerocallis Fulvs ), also known as day lily, commonly known as lily flower, is a perennial herb of Liliaceae, and its edible part is a flower bud. It is a characteristic vegetable in my country. Day lily has high nutritional value, contains carbohydrates, protein, vitamins, inorganic salts and various essential amino acids, and is delicious and popular among consumers. Fresh day lily has high water content, strong respiratory metabolism after harvest, and tender tissues, which are easily infected by bacteria, molds, yeasts and other microorganisms, resulting in putrefaction and deterioration. Fresh day lily will loose buds, bloom, and rot within a day after picking. If it is not kept fresh in time, it will lose its commodity value after a day. [0003] Qidong County is the ma...
