Problems solved by technology

The traditional steam distillation method has a low extraction rate of essential oil (the oil yield of the traditional steam distillation method is generally only 0.15‰~0.3‰), the quality is poor, and the distillation time is long; the organic solvent extraction method requires a large amount of (raw material Twice the weight) Volatile and flammable solvent, very unsafe, and it is difficult to purify the product

Embodiment 1

[0031] A preparation method of hard candy containing rose volatile oil, comprising the following steps:

[0032] (1) Extraction method of rose volatile oil: freshly harvested roses and water are mixed according to the weight ratio of 1:3.5, and after mixing, ultrasonic wall breaking treatment is performed, and supercritical CO2 is extracted after ultrasonication for 1 hour, and the extraction pressure is 20 -21MPa, extraction temperature 45-48°C, separation pressure 8MPa, separation temperature 42-45°C to obtain rose flower volatile oil.

[0033] (2) Low-temperature vacuum freeze-drying and crushing of rose residue: first, pre-freeze the rose residue at -5°C-10°C for 15 minutes, then freeze at -30°C for 2 hours to fully freeze the water, and vacuum freeze the residue after freezing Drying, control the vacuum degree in the box to 10-15 Pa, so when the freeze-drying starts, the temperature of the heat shield is controlled at 50-53°C for sublimation and drying for 8 hours. The t...

Abstract

The invention discloses a hard candy containing rose flower volatile oil, and a preparation method thereof, and belongs to the technical field of natural product extraction and food processing. According to the preparation method, in rose flower volatile oil extraction, rose flowers and water are subjected to ultrasonic wave wall broken; after wall broken, supercritical CO2 extraction is adopted to extract the rose flower volatile oil, and left rose flower residue is subjected to freeze drying, and is smashed into particles with a particle size of 100 to 120<mu>m. The hard candy is prepared from, by weight, 30 to 35 parts of sucrose, 5 to 10 parts of rose flower pollen, 0.1 to 0.25 part of citric acid, 0.3 to 0.5 part of an edible essence, 0.1 to 0.6 part of the rose flower volatile oil, and 10 to 25 parts of water. The preparation method comprises steps of sugar dissolving, filtering, boiling, adding of accessory materials, blending, moulding, and screening. The mouthfeel of the hard candy is excellent; the hard candy possesses rose flavor and health care effect; rose resource utilization range is widened; candy flavor and mouthfeel are improved; absorption on effective components is improved; and a novel product is provided for food market.

Description

technical field [0001] The invention relates to a hard candy containing rose volatile oil and a preparation method thereof, belonging to the technical field of natural product extraction and food processing. Background technique [0002] Candies are common snacks in daily life. They come in many varieties and are constantly being introduced. In addition to the more traditional milk-flavored and fruit-flavored candies, there are also many candies added with medicinal materials, such as ginseng candies and throat lozenges, to meet the preferences of different groups of people. , roses are mainly produced in Yongdeng, Gansu, Pingyin, Shandong, Miaofeng Mountain, Beijing, and Xinjiang in China. They have the functions of regulating qi, detoxification, relieving pain, liver and stomach pain, and are rich in vitamin C, citric acid, and malic acid. It is more common to use rose volatile oil for beauty treatment, medicine, etc., but it has not been reported so far as a candy develop...
