Abstract
The invention discloses a drying and color-retaining method for camellia petals. The drying and color-retaining method comprises the following steps of: soaking bright red, full and half-opened camellia flowers without black spots in a shape protection liquid for 20 minutes after the camellia flowers are picked off to protect the shape of the camellia petals and prevent the camellia petals from being oxidized to generate color spots, picking off the petals from the camellia flowers after the shapes of the camellia petals are stable, soaking the petals in a tartaric acid solution to protect the stable colors of the petals so that the petals are hard to fade away and can still keep bright colors during enzyme deactivation and drying; and carrying out microwave/steam enzyme deactivation treatment, rapidly deactivating the oxidizing enzymes in the petals to reduce the decompression of nutrients, and drying the petals at 40-70 DEG C till the water content of the petals is less than or equal to 10% to obtain dried camellia petals. Therefore, the drying and color-retaining method for camellia petals, disclosed by the invention, has the advantages of low color fading degree, no color spots, stable shapes of the petals and better toughness of the petals.
Description
Technical field
The present invention relates to the dry technology of petal, be specifically related to the dry color-retention method of camellia petal.
Background technology
Common commercially available dry petal is Chinese rose petal and roseleaf at present, though fresh petal process completes and dries processing, the dry Chinese rose petal and the color of roseleaf do not have fresh petal bright-coloured like that, and it is less to fade, the also less color spot that occurs.But if the camellia petal also is completing of routine and dries processing, taking off of obvious color phenomenon will appear, color spot occurs more, attractive in appearance inadequately, fresh camellia petal also be cannot say for sure to deposit very much simultaneously, and the placement utmost point short time will produce the oxidation spot, therefore the availability of camellia petal is extremely low, can only promptly adopt i.e. usefulness, can't preserve use for a long time, this also is the technical reason that does not have commercially available camellia petal.
Summary of the invention
It is few that technical problem to be solved by this invention provides a kind of color fading, and no color spot occurs, petal form stable, and the petal toughness dry color-retention method of camellia petal preferably.
The present invention solves the problems of the technologies described above the technical scheme that is adopted: the dry color-retention method of camellia petal comprises the steps:
A protects type: the camellia flower of plucking scarlet, full, no blackspot of color and half-open shape, in 20 minutes of this camellia flower harvesting, this camellia flower immersion is protected in the type liquid, soaked 1.5～3 hours, described to protect type liquid formulated by the volume ratio of 20～40ml:100ml by glycerine and water, or formulated by 20～40 g:100ml mass volume ratios by sucrose and water;
B protects look: protect type liquid and soak and to finish, take petal from this camellia flower, clean, immediately petal is immersed concentration expressed in percentage by weight and be in 20～40% the tartaric acid solution, soaked 1～1.5 hour;
C completes: tartaric acid solution soaks and finishes, and pulls petal out, cleans, again petal is placed on the sticking paper of oil and complete, the mode of completing is microwave de-enzyming or steam beating, and microwave de-enzyming is: will place the sticking paper of petalled oil and put into micro-wave oven, complete under 450～550W condition 30～50 seconds; Steam beating is: will place the sticking paper of petalled oil and be placed on and completed on the water surface that boils 40～50 seconds; It is not thorough that microwave de-enzyming is lower than 30 seconds and just completes, and is prone to blackspot after the oven dry, is higher than 50 seconds petals and shrinkage can occur, simultaneously can be by burned; It is not thorough that steam beating is lower than 40 seconds and just completes, and is prone to macula lutea after the oven dry, and it is smoked mashed by steam easily to be higher than 50 seconds, becomes pasty state;
D oven dry: complete finish after, will place the sticking paper of petalled oil and put into air dry oven, under 40～70 ℃ of temperature condition, dry to the petal water content and be not more than 10%, obtain the camellia petal of drying.
In step a, the volume ratio of glycerine and water is 30ml:100ml, and soak time is 2 hours.
In step a, sucrose and water quality volume ratio are 30ml g:100ml, and soak time is 2.5 hours.
In step b, the concentration expressed in percentage by weight of described tartaric acid solution is 30%, soaks 1.2～1.3 hours.
In step c, microwave de-enzyming is to complete under the 500W condition 35～45 seconds; Note preventing that shrinkage from can appear in petal.
Compared with prior art, the invention has the advantages that in 20 minutes that the camellia flower of scarlet, full, no blackspot and half-open shape plucks and protect type with protecting the immersion of type liquid, prevent that color spot from appearring in the petal oxidation, and petal shape is stable, take petal again and protect look with the tartaric acid solution immersion, stablize the petal color, complete like that and dry in just seldom fade, still can keep than chromatic colour; Microwave de-enzyming or steam beating are handled, and make petal internal oxidation enzyme deactivation rapidly, decompose thereby reduce nutrition, dry under 40～70 ℃ of cryogenic conditions then to water content and are not more than 10%, obtain dry camellia petal; This camellia petal fades few, and is bright-colored, no color spot, and the petal form does not become substantially yet, and certain toughness is arranged, and can prevent fragmentation during transfer, has good color and luster and special tea perfume (or spice) after the rehydration; The invention solves like this and conventional complete and dry camellia petal fugitive color, color spot is more, the technological difficulties that the fresh flower holding time is very short; Therefore a kind of color fading of the present invention is few, no color spot appearance, petal form stable, and the petal toughness dry color-retention method of camellia petal preferably.
