Description

A kind of equipment for improving enzyme process depickling esterifying efficiency
Technical field
The invention belongs to edible oil and fat manufacture field, and in particular to a kind of raising enzyme process depickling esterifying efficiency sets It is standby.
Background technology
For enzyme process deacidifying process, many scientific research personnel study and deliver achieving suitable achievement, For example：
(D.K.Bhattacharyya, Deacidification of high~acid such as D.K.Bhattacharyya Rice bran oil by reesterification with monoglycerides [J], Journal of the American Oil Chemists ' Society, 1999,76 (10)：1243~1246) report in 210 DEG C of reaction temperature and Under vacuum condition 10mm Hg, free fatty in Rice oil can be contained by controlling monoglyceride addition Amount drops to 0.5 ± 0.10 to 3.5 ± 0.19% (w/w) by 9.5~35.0% (w/w).But turned using the method There is substantial amounts of monoglyceride in grease after change, easily spumed when using.
(Sengupta R, Bhattacharyya D K, the Effect of monoglycerides on such as Sengupta Enzymatic deacidification of rice bran oil [J], Journal~Oil technologists association Of India, 1996,28:125~130) using free in lipase (M.meihei) catalysis Rice oil Aliphatic acid and monoglyceride react, by controlling the monoglyceride addition can be by free fatty acid content in Rice oil 2%~4% is dropped to by 8.6%~16.9%.However it is necessary that adding a certain amount of monoglyceride could reduce free fat The content of fat acid.
Li Guihua etc. (Li Guihua etc., learn by the research [J] of high-acid value rice bran oil esterification depickling, Zhengzhou Engineering College Report, 2002 (1)：36~38) report the method that chemical esterification reduces Rice oil acid value.But due to useization Esterification is learned, causes that the method needs hot conditions and catalyst is easily remained.
(Wang Shirang etc., the research [J] of high-acid value grease esterification deacidification new technology, food industry section such as Wang Shirang Skill, 2010 (3)：252~pre-esterification 255) is carried out to peracid value rice bran oil in the reactor of 2MPa nitrogen charging Process, 180 DEG C of pre-esterification temperature, time 4h, the FFA of rice bran oil is dropped to from 20.5% with this understanding 13.8%；Then the optimal bar of immobilized lipase enzyme process esterification deacidification reaction under the conditions of 2MPa nitrogen charging is drawn Part：55 DEG C of esterification temperature, glycerine addition is 0.31g, esterification time 8h, immobilized lipase addition It is oily weight 5%, drier addition weighs 1.5% for oil, and the FFA of rice bran oil is by 13.18% with this understanding It is down to 2.12%.The document provides a kind of pretreating process of raw material, but the method passes through high-temperature pressurizing reality Existing, pretreatment condition requirement is high, and efficiency is relatively low.
US4698186 discloses a kind of method for reducing free fatty acid content in grease.The method is with acidity Cation-exchanger catalysis reduces the free fatty acid content in grease.But methyl alcohol is the method use, sun The auxiliary materials such as ion exchange resin, are not suitable for fats and oils processing and industrialized production.
WO2004/043894A1 discloses a kind of method that enzyme law catalysis are esterified fish oil.The method passes through enzyme process Carried out after esterification fish oil molecule arrange it is separate to rich in EPA (C20:5) with DHA (from C22:6) ester Method.But sweet three ester of fish oil is directly destroyed and obtains ethyl ester by the method, to Rice oil enzyme process esterification technique There is no application value.
CN101319167A discloses a kind of technique of high-acid value rice bran oil esterification depickling.The method is mainly led to Cross carries out esterification by degumming, decolouring grease under the catalysis of zinc oxide or zinc, obtain acid number for 5~ The low acid value rice bran oil of 7mgKOH/g.But the method reaction temperature is high, and there is the risk of metallic pollution.
CN101824364A discloses a kind of enzyme process method for acid stripping and refining of peracid value fish oil.The method passes through Methyl alcohol, ethanol etc. are added in peracid value fish oil by immobilization packed bed enzyme reactor, will be dissociated in fish oil Aliphatic acid changes into ethyl ester, the technique for then carrying out alkali refining washing and drying.But the enzyme preparation of the technique is easily lost It is living, and ethyl ester can be lost during follow-up refining, it is necessary to individually treatment.
Although there is the technique for some patents disclosing chemical esterification depickling and enzyme process esterification deacidification at present, these Method is that the exploration of acid value grease raising yield high serves positive effect.But, these methods such as chemistry Method influences larger to oil quality, and enzyme process still then is limited to laboratory's rank, and it is long to there is the reaction time, turns The low problem of rate.
