Abstract
The invention relates to a method for extracting natural rose color element from rose flowers, comprising the following steps: the rose flowers are washed and added with water for mixing; the mixture is completely frozen and then heated by water bath to be rapidly melted; water immersion is carried out to extract concentrated solution; organic solvent is added into the concentrated solution for extracting; and the rose color element solid is obtained after concentration and drying. The freezing-melting extraction refining method is adopted to extract the natural rose color element and the method requires mild condition and has simple operation and low cost without pollution.
Description
Technical field
The present invention relates to a kind of method of from fresh rose flower, extracting the natural rose haematochrome,
Background technology
According to the difference in source, food coloring mainly is divided into two big classes, promptly edible natural colouring matter and edible synthesized coloring matter.In recent decades, people have found the harmfulness of some synthetic dyestuff gradually, and to making some countries of Europe begin to ban use of synthetic dyestuff as food additives, China has also done corresponding restriction and used and forbid.Therefore, utilizing nontoxic natural materials to extract natural food colour is the main trend of the world today.The natural rose haematochrome is topmost source in the haematochrome.
The cultivation of rose has long history in China, from south to north, and widely plantation from west to east, arrive Guangdong, Yunnan as south, Inner Mongol, Shanxi, west longitude Xinjiang, Gansu are arrived in north, east is to Shandong, and all there is the plantation of rose in Zhejiang, and a large amount of rose outputs is all arranged every year.In China, rose is mainly used to produce elementary, low-end products such as Rosa Damascana, rose flavored juice, rose tea, rose beverage, cider, the value of industrial crops rose can not demonstrate fully, cause these industrial crops not bring due economic benefit thus, thereby limited the popularizing planting of rose.
Summary of the invention
The purpose of this invention is to provide a kind of method of from fresh rose flower, extracting the natural rose haematochrome, by freezing---melt, the extracting and refining method is extracted the natural rose haematochrome, this method mild condition, and simple to operate, cost is low, and is pollution-free.
The present invention carries out according to the following steps:
A, preliminary treatment: the raw material fresh rose flower is taken colored sheet, clean, the salt salt marsh with 10% adds the water mixing that raw material weighs 2～3 times of weight portions after 1～5 day;
B, freeze---melt: above-mentioned material liquid mixture is put into-30 ℃～-4 ℃ refrigerator, treat that it freezes fully after, the water-bath heating is melted it fast, and stirs 2～3 times repeatedly;
C, flooding: will add the water of 2～10 times of weight portions in the above-mentioned material liquid mixture, in 30 ℃～55 ℃ water-baths, extract twice, each 1～2 hour, then supernatant is collected in the leaching liquor centrifugation, precipitation repeats lixiviate twice, merges supernatant, and decompression concentrates and obtains concentrate;
D, extracting and refining: described concentrate is added 1～3 times of parts by volume organic solvent extracting twice repeatedly, and each 30min collects extract;
E, concentrate drying: described extract is condensed into paste with it in water-bath,, obtains the rose-bengal pigment solid in vacuum drying below 60 ℃.
Described flooding process will constantly stir.
Described organic solvent can be ethanol or propane diols.
The invention has the beneficial effects as follows:
1, employing is freezed repeatedly---the broken rose cell wall of the method for melting, promoted the rapid stripping of DDGS in the cell, and shortened extraction time greatly, improved extraction rate.
2, refining with organic solvent extraction, removed pectin, impurity such as protein have guaranteed the purity of pigment.
3, freeze---melt the method mild condition, operating temperature is not high, and the whole process of preparation temperature is lower than 60 ℃, and the natural colouring matter high to thermal sensitivity destroys less.
