Description
Technical field
The present invention relates to a kind of preparation method of high luminance relay valency monascorubin, especially relating to a kind of is raw material is produced monascorubin by microorganism liquid state fermentation technology method with the rice.
Background technology
Red colouring agent for food, also used as a Chinese medicine is the traditional medicine-food two-purpose rice fermented products of China, in the history in existing more than 1000 year of China.It is with Chinese distinctive monascus ruber solid-state cultivation and fermentation in rice, and grinds after the drying and make, because contain red pigments, and is scarlet, so be referred to as red colouring agent for food, also used as a Chinese medicine.It once was emperor's in ancient times a protective foods, and just there is the record of " cooking meat with red colouring agent for food, also used as a Chinese medicine " period in Tang of Sui.Before modern more than 600 year, the pharmacy man LI Shi-Zhen in Ancient Chinese generation is included Red kojic rice in Compendium of Material Medica first, accurately explained Red kojic rice activate blood circulation and disperse blood clots, strengthening the spleen to promote digestion, medicinal function aspect enhancing metabolism, be widely used among food color, fermented product and the Chinese materia medica.As natural additive for foodstuff, red colouring agent for food, also used as a Chinese medicine has advantages such as lovely luster, strong coloring force, Heat stability is good, at wine brewing, system vinegar, beverage, fermented bean curd, particularly will substitute the nitrite additive that colouring function is arranged of carcinogenic hidden danger in meat products such as ham sausage.
Contained red pigments in the red colouring agent for food, also used as a Chinese medicine is the mixture of multiple material, and up to now, the red colouring agent for food, also used as a Chinese medicine composition that has identified comprises kinds more than 20 such as monascorubin, red colouring agent for food, also used as a Chinese medicine element, ankaflavin, Lovastain.Along with going deep into of research, find that red colouring agent for food, also used as a Chinese medicine has the multiple functional active components that comprises Lovastain, these activeconstituentss are all effective in cure to cardiovascular and cerebrovascular diseases, diarrhoea, cancers such as hypertension, hyperglycemia, hyperlipidemia, hypercholesterolemia, atherosclerosiss, caught people's attention.
The method of producing monascorubin at present mainly contains two kinds: a kind of is the solid state fermentation extraction method, monascus ruber is seeded in the rice after the boiling, form through solid-state cultivation and fermentation, and grind after the drying, form with organic solvent extraction such as alcohol pigment drying wherein again, it is less investment that solid state fermentation is produced the monascorubin biggest advantage, and maximum shortcoming is that labour intensity is big; Another kind method is the liquid state fermentation extraction method, and the rice fragmentation is equipped with other auxiliary materials and adds water, and inoculation red colouring agent for food, also used as a Chinese medicine bacterial classification is after liquid state fermentation, and concentrate drying forms after filtration, and its advantage is the level of automation height, and shortcoming is that one-time investment is relatively large.
The selling price of monascorubin depends primarily on the height of its look valency, and the high more selling price of look valency is also higher relatively.And no matter existing preparation method is the solid state fermentation extraction method, or the liquid state fermentation extraction method, the monascorubin of its preparation, and the look valency is all lower.Therefore, how improving the look valency on the basis that reduces cost is the focus and the difficult point problem of this area research.
Summary of the invention
The objective of the invention is to overcome the above-mentioned defective that prior art exists, provide a kind of product look valency higher, and production cost is lower, the monascorubin preparation method that environmental pollution is few.
The objective of the invention is to be achieved through the following technical solutions, it may further comprise the steps: the preparation of (1) Rice ﹠ peanut milk: rice fragmentation, immersion, add the amylase that is equivalent to rice weight 0.1-0.2%, and be incubated 60-90 minute down at 40 ℃-50 ℃, make Rice ﹠ peanut milk; (2) fermentation culture preparation: in Rice ﹠ peanut milk, add SODIUMNITRATE, 0.15-0.25% potassium primary phosphate, 0.15-0.25% magnesium sulfate heptahydrate, 1-1.5% corn steep liquor, the 1.5-2% analysis for soybean powder that is equivalent to Rice ﹠ peanut milk weight 0.2-0.25%, adjusting pH with lactic acid is 4.5-5.5, being heated to 121 ℃ kept 20 minutes, be cooled to 35 ℃-40 ℃, make fermentation culture; (3) red colouring agent for food, also used as a Chinese medicine strain expanded culture: with the red colouring agent for food, also used as a Chinese medicine bacterial classification Monascus purpureus that preserves, behind solid slant culture, be inoculated into seed culture medium and cultivated 50 hours down, make and produce with red colouring agent for food, also used as a Chinese medicine strain expanded culture liquid at 31 ℃-33 ℃; (4) fermentation culture: the red colouring agent for food, also used as a Chinese medicine strain expanded culture liquid that will be equivalent to fermentation culture 8-10wt% adds in the fermentation culture that is cooled to 35 ℃-40 ℃, cultivated 85-100 hour 31 ℃-37 ℃ following insulated and stirred, the fermentor tank tank pressure keeps 0.04-0.06MPa, stirring velocity is 180-190r/min, makes fermented liquid; (5) high luminance relay valency monascorubin powder is produced: with filtering fermentation liquor, filtrate gets concentrated solution through membrane concentration, spray-dried again or lyophilize;
Described solid slant culture with the slant culture based formulas is: Zulkovsky starch 3.5wt%, and maltose 4wt%, agar 2wt%, Yu Weishui, pH are 5.2-5.6;
Described seed culture based formulas is: ground rice wt7%, SODIUMNITRATE 0.2wt%, potassium primary phosphate 0.15wt%, magnesium sulfate heptahydrate 0.15wt%, corn steep liquor 2wt%, analysis for soybean powder 3wt%, Yu Weishui; PH is 5.2-5.6.
Filter residue behind the filtering fermentation liquor, still residual have a part monascorubin.For improving the monascorubin productive rate, to monascorubin contained in the filter residue, available alcohol lixiviate is extracted.The concrete practice is as follows: filter residue with concentration 70% (v/v) alcohol lixiviate 1-1.5 hour, is refiltered, and behind the filtrate membrane concentration recovered alcohol, with the concentrated solution merging first time, concentrated solution spraying drying or lyophilize after will merging promptly get the monascorubin powder again.
Described red colouring agent for food, also used as a Chinese medicine bacterial classification Monascus purpureus is known common microorganism (referring to " bacterial classification catalogue ", Chinese agriculture press,, a third edition [in 2003), and there is sale in market.
The monascorubin that the present invention makes detects by the standard GB 15961-2005 regulation method of inspection, and the look valency can reach more than 200, can be widely used in fields such as foodstuff additive, protective foods, medicine, chemical industry.
Filter residue can be used for animal-feed.
