Definitions
- the present invention relates generally to lecithin conversion. More particularly, this invention relates to an improved method of enzymatic conversion of lecithin to produce lysolecithin. Even more particularly, this invention relates to a method of simultaneously producing lysolipid, lysophosphohpid, and mono- and diglycerides from lecithin.
- Lecithin and lysolecithin have been used in various industries as emulsifiers. These emulsifiers are used in a variety of products, e.g., foods, cosmetics, drugs, nutritional supplements, and chemicals.
- Enzymatic conversion of phosphatidylcholine to lysophosphatidylcholine has been known for years. Previous researchers have determined that several factors such as pH, temperature, and surface concentration of the molecules affect this conversion. Additionally, presence or absence of particular ions, such as calcium, or solvents have been determined to affect the conversion process.
- the process of the current invention converts lecithin at a higher conversion rate while using lecithin, rather than phosphatidylcholine, and producing a desired, product containing lysolipids, lysophospholipids, and mono- and diglycerides.
- Another object of the invention is to provide a method which simultaneously converts lipids and phospholipids of crude lecithin into lysolipids, lysophospholipids, and mono- and diglycerides.
- Another object of the invention is to provide a method which simultaneously converts lipids and phospholipids of crude lecithin into lysolipids, lysophospholipids, and mono- and diglycerides at a greater conversion percentage than prior art methods.
- the invention is a method for the improved conversion of lipids and phospholipids present in crude lecithin into their lyso- forms and the simultaneous production of mono- and diglycerides to get an improved emulsifier.
- This conversion is performed by means of an enzymatic treatment.
- the enzymatic treatment consists of the hydrolysis and/or alcoholysis of lipids and phospholipids in a water/polyol mixture, by means of a blend of lipase and phospholipase A2.
- the lipase cleaves ester bonds of the lipids and produces glycerol and mono- and diglycerides.
- the phospholipase A2 cleaves the ester bond of the phospholipids at the C2 position of the glycerol backbone.
- the resultant lysophospholipids are surface-active amphiphiles that contain only one long chain fatty acyl group and a large polar head group consisting of a free hydroxyl on the glycerol backbone and an anionic or zwitterionic moiety bonded to the same backbone via a phosphate ester.
- Common moieties include choline, ethanolamine, and inositol.
- the conversion is performed by incubating lecithin with the lipase- phospholipase mixture in an aqueous/polyol environment with or without the addition of calcium chloride (CaCl ) to capture the released fatty acids.
- the lecithin is mixed with water and polyols at 40-50 °C that has been made slightly basic. This mixture is
- the present method is able to increase the conversion percentage while simultaneously producing mono- and diglycerides.
- Figure 1 is a high-performance liquid chromatography- evaporative light- scattering detector (HPLC-ELSD) chromatogram of crude lecithin.
- HPLC-ELSD high-performance liquid chromatography- evaporative light- scattering detector
- Figure 2 is a HPLC-ELSD chromatogram of the product of Example 1.
- Figure 3 is a HPLC-ELSD chromatogram of the product of Example 2.
- Figure 4 is a HPLC-ELSD chromatogram of the product of Example 3.
- the invention is an improved method for simultaneously producing lysolipids, lysophospholipids, and mono- and diglycerides from crude lecithin.
- the method produces a high conversion rate of over 80% based on the ratio of LPC/PC (lysophosphatidylcholine/phosphatidylcholine) in a single step.
- Crude lecithin can be used in the process of the current invention.
- Prior art processes generally use phosphatidylcholine.
- Lecithin is available from various commercial sources.
- the lecithin is added to a water/polyol mixture.
- the water/polyol is in a 6 to 1 weight ratio.
- the lecithin is added to the mixture in a 3 to 7 weight ratio.
- the water/polyol mixture is at about 40°C to
- the pH of the mixture is preferred to be about 7 to 8.
- the range of pH that will work depends on the workable pH range of both lipase and phospholipase A2.
- the pH may be adjusted using a base.
- a base that has been used is sodium hydroxide (NaOH) at ION. Any base may be used as long as it does not interfere with the desired reactions. It is desired to keep the combination of lecithin/water/polyol at a constant pH.
- a pH-stat has been used to achieve a constant pH.
- the combination of lecithin/water/polyol is preferably continuously stirred.
- a blend of lipase and phospholipase A2 is added to the lecithin/water/polyol combination.
- the lipase and phospholipase A2 enzymes are available from various commercial sources.
- a lipase/phospholipase A2 mixture from Lovesgrove Research Ltd. has been used.
- the conversion can be performed with any other combination of lipase and phospholipase A2 as long as there is an overlap in their workable pH range.
- the activities of the enzymes used in the examples was about 16 units per gram of crude lecithin for the lipase and about 48 units per gram of crude lecithin for the phospholipase A2.
- One phospholipase unit is equal to the amount of enzyme that
- Calcium chloride (CaCl 2 ) can be added to the mixture, though it is not necessary. Calcium chloride is available from various commercial sources. Calcium ions catch the fatty acids that are released during the conversion. Any compound which serves this function but does not interfere with the desired results may be used.
- the calcium chloride can be added at an amount in moles from zero up to half the number of moles of fatty acids expected to be released during incubation.
- Example 1 Four hundred twenty grams (420 g) of water and 70 g glycerol were mixed. The pH of the mixture was adjusted to 7.5 with NaOH ION. This mixture was stirred at approximately 100 rpm and kept at a temperature of 50°C. The pH was kept
- a lipase-phospholipase A2 enzyme mixture was added. Two hundred ten grams (210 g) crude lecithin was added, and the mixture was incubated for 18 hours.
- Table 1 shows the results of Examples 1-3. There was 3.3% LPC of
- Example 2 Three thousand grams (3000 g) water and 500 g glycerol were mixed. The pH of the mixture was adjusted to 7.5 using NaOH ION. This mixture was stirred at
- a lipase-phospholipase A2 enzyme mixture was added.
- One thousand one hundred ten grams (1110 g) crude lecithin was added, and the mixture was incubated for 21 hours.
- Table 1 shows the results of Examples 1-3.
- the crude lecithin starting material was the same as that of Example 1, i.e., containing 3.3% LPC of (LPC+PC).
- the resulting product of this procedure contained 94.4% LPC of (LPC+PC). See Figures 1 and 4 for the chromatograms of the starting and ending materials.
- Example 3 Product 94.4
- Example 4 A competitor's modified lecithin was compared against lecithin converted by the process of the current invention using both P-NMR and the HPLC-ELSD methods. The results are given in Table 2. The Lovesgrove modified lecithin is made via a bacterial/enzymatic conversion using phospholipase A2 (see UK and PCT patent No. 9205014.5 and U.S. Patent 5,759,537).
