Rose petal fresh-keeping formula and fresh-keeping method

Abstract

The invention discloses a rose petal fresh-keeping formula. The rose petal fresh-keeping formula comprises, by mass, 1%-99.7% of fresh rose petals, 0.1%-30% of edible salt, 0.1%-50% of D-sodium erythorbate and 0.1%-20% of citric acid. The rose petal fresh-keeping method comprises the steps of petal picking, cleaning and airing, fresh-keeping ingredient treatment and packaging and refrigeration, wherein after petal picking is conducted, cleaning and airing are conducted, fresh-keeping ingredient treatment is conducted, and packaging and refrigeration are conducted. The formula and the corresponding fresh-keeping method can prolong the refreshing time of rose petals to one year, the fresh-keeping cost is low, the occupied area is small, discoloration, off odor and deformation do not occur for the petals, and original odor, mouthfeel and biological tissue structure of the rose petals are preserved.

Description

technical field [0001] The invention relates to the technical field of preservation of edible rose petals, in particular to a fresh-keeping formula and fresh-keeping method of rose petals. Background technique [0002] The fresh-keeping technology of roses is mainly used in the field of fresh-cut flowers, but the "fresh-keeping" mentioned here still refers to the short-term fresh-keeping, which generally cannot exceed one month, and the cost of fresh-keeping is relatively high. Generally, it takes 24-48 hours. It is necessary to replace the fresh-keeping liquid, and the fresh-keeping rose must be a relatively complete plant with unseparated branches and flowers, which brings about a huge waste of space. Features, this preservation method still has its greater economic value.

Problems solved by technology

[0002] The fresh-keeping technology of roses is mainly used in the field of fresh-cut flowers, but the "fresh-keeping" mentioned here still refers to the short-term fresh-keeping, which generally cannot exceed one month, and the cost of fresh-keeping is relatively high. Generally, it takes 24-48 hours. It is necessary to replace the fresh-keeping liquid, and the fresh-keeping rose must be a relatively complete plant with unseparated branches and flowers, which brings about a huge waste of space. characteristics, this fresh-keeping method still has its great economic value

[0003] But as edible type rose above-mentioned fresh-keeping is undoubtedly inapplicable, just added a large amount of bactericides and just violated the safety promise of food, there are more rose fresh-keeping technologies in the prior art, but all are for Fresh-cut fresh-keeping techniques, the essence of these techniques lies in the difference in the formulation of the fresh-keeping solution, and the requirements for picking rose plants are the same. These fresh-keeping techniques are not suitable for the preservation of edible rose petals, edible roses Flower petals are mainly used to process various flower foods in the prior art, and the most important food is flower cakes. The stuffing of flower cakes is mainly made of fresh rose petals. Edible rose petals have a tradition of many years in our country. There are also a large number of existing technologies for its preservation methods. The main production and preservation methods are to "dry" the dried rose petals with edible sugar or honey. In Yunnan, the rose petals obtained by this production method are called " "Bad roses" or "sugar bad roses", but this kind of processing will make the fragrance and taste of fresh roses lose a lot, and the fragrance of rose petals will be covered by a lot of sugar or honey, and the taste will only be bitter. dried petals

[0004] The flowering period of roses in my country is mainly from May to October each year (roses grown in natural fields, greenhouse flowers are not within the scope of consideration of the present invention, because the cost of greenhouses is relatively high, it is not suitable for support flower food, only applicable It is sold in fresh cut flowers. The flowering period mentioned here is from May to October, which includes the flowering period in all parts of the country, and the northern region is only in the flowering period from May to June), but the peak period is from May to June, which leads to fresh roses. The problem that flower petals cannot be supplied throughout the year has led to the cessation of production, and it is impossible to quickly convert a large number of rose petals into products during the flowering period. The existing technologies simply use refrigeration, but simple The cold storage can only prolong the shelf life by 3-6 months, and it cannot be supplied throughout the year, which greatly affects the prospect of roses being used in the edible processing industry.
