Abstract
The invention relates to a medlar drying promotion color fixative and a use method thereof. The drying promotion color fixative comprises the following components by weight percent: 5-10 percent of ethanol, 0.2-0.5 percent of sodium pyrosulfite, 0.5-1 percent of potassium sorbate and rest percent of alkali metal carbonate. The use method comprises the following steps: evenly mixing sodium pyrosulfite, potassium sorbate and alkali metal carbonate according to the weight percents, dissolving the mixture in water by solid-to-liquid ratio of 1-2g:100ml, evenly agitating, adding ethanol, evenly mixing to obtain medlar drying promotion color fixative solution, dipping fresh medlars in the solution for 0.5-1 minute, fishing out the fresh medlars and draining water, flatly laying the fresh medlars on bamboo mats or trays and drying the medlars.
Description
Technical field
The present invention relates to the fruit and vegetable dryness preservation technique.
Background technology
Chinese wolfberry fruit moisture content height is difficult for the transportation storage, can make its long term storage keep nutritional labeling by effective technique for preparing dry.Because the matrimony vine epidermis has one deck wax quilt, its main component is aliphatic compound, cyclic compound and phytosterin compound, and wax has hindered the evaporation of moisture in dry run, the efficient that influence is dry.Chinese patent CN1356051A discloses and has a kind ofly prepared grape or medlar drying promotion agent with vegetable and animals oils, and this drying promoter is made up of vegetable and animals oils, ethanol, alkali metal hydroxide, alkali carbonate.This method complicated operation is difficult for implementing, so be difficult to promote.Chinese patent CN101322549A discloses a kind of agent special for protecting color and making dried medlar, and raw material is edible soda ash, natrium citricum, sodium iso-vc and potassium sorbate.These method food additives are many, and cost is higher, and short dried efficient is not remarkable.
Summary of the invention
The purpose of this invention is to provide a kind of medlar drying promotion color fixative and using method thereof.
The present invention is a kind of medlar drying promotion color fixative and using method thereof, and by mass percentage, the component of its drying promotion color fixative is: ethanol 5～10%, and sodium pyrosulfite, 0.2～0.5%, potassium sorbate 0.5～1%, surplus is an alkali carbonate.
The using method of medlar drying promotion color fixative the steps include: by above-described component, with sodium pyrosulfite, potassium sorbate, alkali carbonate evenly mixes, and is water-soluble with the ratio of solid-to-liquid ratio 1～2g: 100ml, stir, and then adding ethanol, mix, promptly get medlar drying promotion color fixative solution, medlar fresh fruit was flooded 0.5～1 minute, pull the fresh fruit drop branch that anhydrates out, on tiling bamboo mat or the pallet, make dried.
The alkali carbonate that the present invention adopts can destroy the Chinese wolfberry fruit wax coat, increases fruit moisture and distributes speed, has improved drying efficiency; Ethanol can destroy the epicutile wax layer to a certain extent, and has the effect of sterilization and quickening water evaporates; Sodium pyrosulfite has hyperchromic corrosion-resistant effect; Potassium sorbate has the effect of anti-corrosive fresh-keeping.The present invention is easy and simple to handle, and cost is low, under the prerequisite that guarantees the Chinese wolfberry fruit nutritional quality, has shortened matrimony vine drying time, can improve the storage quality of matrimony vine.
The specific embodiment
The present invention is a kind of medlar drying promotion color fixative and using method thereof, and by mass percentage, the component of its drying promotion color fixative is: ethanol 5～10%, and sodium pyrosulfite, 0.2～0.5%, potassium sorbate 0.5～1%, surplus is an alkali carbonate.Alkali carbonate is a potash, or sodium carbonate, or its mixture.
The using method of medlar drying promotion color fixative the steps include: by above-described component, with sodium pyrosulfite, potassium sorbate, alkali carbonate evenly mixes, and is water-soluble with the ratio of solid-to-liquid ratio 1～2g: 100ml, stir, and then adding ethanol, mix, promptly get medlar drying promotion color fixative solution, medlar fresh fruit was flooded 0.5～1 minute, pull the fresh fruit drop branch that anhydrates out, on tiling bamboo mat or the pallet, make dried.
Embodiment 1
By mass percentage, the sodium carbonate of ethanol 8%, sodium pyrosulfite 0.2%, potassium sorbate 0.5% and surplus is mixed, soluble in water with the solid-to-liquid ratio of 1g: 100ml, can obtain the drying promotion color fixative product.With this drying promotion color fixative dipping medlar fresh fruit 0.5 minute, the back take out drain and bamboo mat that the 1.5cm that tiles is thick on make driedly, when fine weather, the time that is dried to GB does not more use the control group of drying promoter to shorten more than 20 hours, and color and luster is pure; When rainy weather, the time that is dried to GB does not more use the control group of drying promoter to shorten more than 40 hours, and black fruit rate is low more than 60% than control group.
Embodiment 2
By mass percentage, the sodium carbonate of ethanol 5%, sodium pyrosulfite 0.3%, potassium sorbate 1% and surplus is mixed, soluble in water with the solid-to-liquid ratio of 1.2g: 100ml, can obtain the drying promotion color fixative product.Flooded medlar fresh fruit 0.6 minute with this drying promotion color fixative, make dried on the bamboo mat that the back taking-up drains and the 1.2cm that tiles is thick, when fine day, the time that is dried to GB does not more use the control group of drying promoter to shorten more than 25 hours, color and luster is pure, when rainy weather, the time that is dried to GB does not more use the control group of drying promoter to shorten more than 45 hours, and black fruit rate is low more than 70% than control group.
Embodiment 3
Sodium carbonate with ethanol 10%, sodium pyrosulfite 0.4%, potassium sorbate 0.3% and surplus mixes by weight ratio, and is soluble in water with the solid-to-liquid ratio of 1.5g: 100ml, can obtain the drying promotion color fixative product.With this drying promotion color fixative dipping medlar fresh fruit 0.8min, the back take out drain and bamboo mat that the 1cm that tiles is thick on make driedly, when fine day, the time that is dried to GB does not more use the control group of drying promoter to shorten more than 30 hours, color and luster is pure; When rainy weather, the time that is dried to GB does not more use the control group of drying promoter to shorten more than 45 hours, and black fruit rate is low more than 70% than control group.
