Problems solved by technology

Its treatment of rose petals is that the petals are directly in contact with preservatives. Salt tends to dehydrate the petals and carry a salty taste, which affects the taste and cannot keep the petals fresh.
In addition, technologies for storing petals at sub-zero temperatures, such as "A Method for Frozen Storage of Rose Flowers" disclosed in Chinese patent application CN1026130015A and Chinese patent application CN106719606A, all store petals at low temperatures below zero. storage time, but after freezing, the color, texture and fragrance of the petals will change, losing the fresh state of rose petals

Abstract

The invention provides a fresh-keeping method for edible rose petals. The fresh-keeping method is characterized by comprising the following steps: 1) picking flowers; (2) carrying out primary precooling at the temperature of 12-18 DEG C and the humidity of 80-90%, and sorting petals at the same time; (3) feeding into a refrigeration house with the temperature of 4-8 DEG C and the humidity of 80-85%, and carrying out secondary precooling for 2-4 hours; (4) sub-packaging the rose petals into OPP (Oriented Polypropylene) fresh-keeping bags, assembling 4-6g of ethylene absorbent according to 1.0 kg of the rose petals, and assembling 8-10g of walnut shell activated carbon according to 1.0 kg of the rose petals, and (5) storing the rose petals in a refrigeration house with the temperature of 2.0 + / -0.5 DEG C. The whole storage process is green, environment-friendly, safe and non-toxic, the flower color, shape, fragrance and the like of the petals are maintained, the fresh-keeping time of the rose petals is 80-90 days, which is more than two times of that of the conventional fresh-keeping time of 30-40 days, and the market demand can be met.

Description

technical field [0001] The invention relates to a fresh-keeping method for edible rose petals, belonging to the technical field of fresh-keeping flowers. Background technique [0002] Edible roses are plants of the Rosaceae (Rosaceae) genus Rosa. Its flowers have a strong fragrance. The petals are rich in protein, fat, crude fiber, amino acids, vitamins and mineral elements and other nutrients necessary for the human body. It has detoxification and beauty. , qi and blood circulation and other effects. In recent years, people have developed a series of products such as rose sauce, rose fillings for various snacks, rose tea, rose essential oil and perfume with edible rose petals as raw materials, and the demand for edible roses is increasing year by year. But because edible rose harvesting period is shorter, only can gather fresh rose every year from April to October, and the petal of fresh rose is difficult to store for a long time, has limited the development of edible rose...
