Definitions
- This invention relates to an improved process for producing a whey protein concentrate having a serum albumin content of about 9% or more.
- Dietary W.P.C. produced with lower levels of heat treatment improves systemic humoral immune response, increases the resistance of target cells against the effect of carcinogens including chemical carcinogens such as dimethylhydrazine, improves resistance to pneumococcal infection, and provides a sustained increase of tissue (intracellular) glutathione.
- the object of this invention is to provide an improved process for preparing a whey protein concentrate that has adequately low bacterial levels without excessive levels of protein denaturation. It is a particular object to provide a process that will achieve a whey protein concentrate having a serum albumin of about 9% and adequate bacterial reduction. This approximately 9% level of serum albumin was found in our studies to be important for the achievement of sustained increase of tissue glutathione for the properties such as improved systemic humoral immune response described above (References 2 and 3).
- the use of process conditions to give a high serum albumin content will also give a high content of such other Glu-Cys containing proteins.
- Serum albumin is the most easily denatured serum protein since its denaturation is not as reversible as that of alpha-lactalbumin (4). It therefore is a further object of this invention to maintain rigorous control of temperature and other conditions to minimize denaturation of serum albumin.
- the casein in raw milk occurs in the form of a colloidal dispersion.
- the particles of this dispersion range from 20 to 200 nm (nanometers) in diameter and are generally referred to as casein micelles.
- the industrial methods of separation of the casein are based on the destabilization of these proteins either by lowering the pH of milk to the isoelectric point (pH 4.6) at 20°C or by enzymatic (rennet) hydrolysis of the Kappa casein which stabilizes the micelles.
- the first procedure is not suitable for the recovery of native whey proteins since low pH has been shown to denature Bovine serum albumin, apparently because of repulsion of acidic amino acids (Haurowitz, 1963) (11). Furthermore, if excessively high temperatures are used in this procedure, there would be a considerable increase in the denaturing effect of a low pH.
- the second procedure is less economically feasible because the caseins recovered are less functional for dairy industry use.
- the objective is to develop a combination of method steps which are compatible with cheese making.
- the cheese represents roughly 10% (by weight) of milk being treated and the whey represents approximately 90%, of which 0.6 to 0.7% consists of whey proteins.
- Moisture content was determined in duplicate by AOAC method (7).
- Total coliforms count was determined following incubation at 37 °C for 18 h in brilliant green using the most probable number method.
- Total bacteria count (aerobic mesophiles) was determined following incubation at 32 °C for 48 h in PCA medium. Both methods are approved by the International Dairy Federation and American Public Health Association.
- Lactose was measured by the enzymatic method. Standardization
- the first step is the standardization of the milk. This involves skimming the milk to a desired fat content. This procedure is used for two reasons. The first is to attain the legal percentage of fat on a dry basis of the final cheese. The second is to achieve the best yield and quality (body and texture) of cheese.
- the usual practice has been to use a temperature in the range of 50 °C to 65 °C as this is the most efficient range for skimming to a level of 0.05% of fat.
- the raw milk used in the examples had the following composition:
- composition % protein 3.2 % fat 3.65 % lactose 4.7
- the pH of the composition was 6.65.
- standardization of milk was carried out with a cold separator (Alfa Laval, CMRPX 714-HGV) coupled with an automatic standardizer (Alfa Laval, Alfast Model 110). All standardization steps were carried out at 4°C. (Figure 1) and for all examples the fat content was adjusted to 3.58% of total milk. The fat content of 3.58% was in accordance with standardization according to the following calculation:
- pasteurization of the milk was achieved on a heat exchanger type HTST (Alfa Laval H-10) being set at 72.6°C with a retention time of 16 sec., followed by flash cooling to 30 °C. Most countries do not allow the production of dairy products without pasteurization. Different types of pasteurization can be used:
- the introduction of high temperature pasteurization of milk was prompted by two different objectives. The first was to obtain a near sterilization of milk following the cheese related infection diseases reported during 1988 in Europe. The second objective was to improve the yield during cheese making.
- the preliminary step in cheese production is to reduce the temperature.
- the temperature is accordingly immediately reduced, such as by flash cooling to a temperature of 30 °C for cheese making.
- Another way of controlling the rate of metabolism is to reduce the fermentation temperature. A reduction of 2°C will normally be used for this purpose.
- the fermentation period was 1.5 hour for our examples at a temperature of 30°C.
- the pH decreased from 6.65 to 6.55.
- the pH drop was thus 0.1 before rennet was added.
- Rennet was added at a rate of 20 ml/ 100 liters of milk.
- the time required for curd formation was 25 minutes.
- the rennet used was a pure calf rennet single strength from CH. Hansens Laboratory. The quantity was 20 ml./lOO liters of milk. The temperature is maintained at 30° C. The rennet was diluted in 10 times its volume with water before adding to milk. The clotting time was 25 minutes. Cheese production - culturing the curd
- the curd was then cut using 6 mm. cheese knives at a temperature of 30°C to provide 6 mm cubes and stirred for 15 minutes before it was cooked.
- Cheese production - cooking In our examples the cooking period lasted 75 min and continuous agitation was used. The peak temperature of 38 °C was reached in 30 minutes (1.3°C per 5 minutes). After this cooking period agitation was maintained for 1 hour.
- the pH of the whey after cooking was 6.5. It is highly desirable to avoid any cheese making steps that involves a temperature in excess of 40° C. In fact some cheese production such as Emmental requires a temperature of more than 50°C. Raising the temperature to this level before separation of the whey and maintaining such temperature would adversely affect the serum albumin content. Following post stirring the curd is separated from the whey.
- the curd should be separated from the whey at this level.
- the whey that has been collected is first pumped at 38° C in a centrifugal separator to take out excess fat (Alfa-Laval MHMRPX-214TGV) that was present during cheese production.
- the amount of fat is reduced to a level of 0.06% in the resulting whey.
- the Ph in our examples was at 6.48.
- the whey is then chilled to 4°C and stored till ultrafiltration (U.F.) is carried out.
- the temperature is then raised at 40°C for the Ultrafiltration (using Romicon cartridge with a cut off of 50,000 Dalton). If necessary it can be given a second pasteurization as shown in Figure 1 under conditions similar to the pasteurization previously described. Whev - pasteurization
- whey was pasteurized. This heat treatment was mainly applied to control the activity of lactic acid bacteria that was previously added to milk. It also serve to control post pasteurization contamination that could occur during cheese making. Ultrafiltration
- the retentate is submitted to diafiltration by adding water so as to reduce the lactose level (4.6%) so that the retentate from ultrafiltration contains less than 1 % of lactose.
- the retentate following completion of ultrafiltration has a total solids of 19-20%.
- the conditions of ultrafiltration are set forth below in Table 1.
- TMP Transmembrane pressure
- the temperature utilized in most other commercial methods during this procedure is 50° C. This level of temperature facilitates a higher flux through the membranes hence more retentate production per unit of time and per unit of membrane. In our method, the draw-back of less production per unit of membrane is compensated by increasing the membrane surface.
- the objective of not exceeding 40 °C is obtained throughout the system by fine tuning the points of input and output in the system so as to avoid a heat producing unbalance between the two.
- the temperature of the retentate is then lowered to 4°C and kept at that temperature till freeze drying is started.
- the composition of the retentate is about 19-20% total solids.
- a typical composition is:
- Vitamins and flavours may, if desired, be added to the retentate after ultrafiltration.
- the retentate may be regarded as a final product and sold in liquid form.
- the retentate can be concentrated to provide a dry product as described below. Whey - Freeze drying
- Concentration to produce a dry product by lyophilization is performed at temperatures under O°C for 15 to 18 hours. This does not denature the themnolabile proteins.
- the retentate was subjected to a blast freeze at -25 °C before entering in the freeze dryer.
- the temperature of the condenser were maintained at -50 °C during the 17 hours of the freeze drying period.
- the microbial counts of the retentate compare favourably with standards applicable to conventional pasteurization. These standards differ in each jurisdiction. As an example, the province of Quebec, Canada, requires that total bacteria count (aerobic mesophiles (32 °C) be maintained below 50,000 (log 4.69), both in the factory and in the final product in the case of powdered milk products. Coliforms are to be below 10.
- the province of Quebec, Canada requires that total bacteria count (aerobic mesophiles (32 °C) be maintained below 50,000 (log 4.69), both in the factory and in the final product in the case of powdered milk products. Coliforms are to be below 10.
- the province of Quebec, Canada requires that total bacteria count (aerobic mesophiles (32 °C) be
- Quebec has a standard of a bacteria count of 25,000 (log 4.39) and a coliform count of 5 in the factory for milk products that have not been pasteurized or fermented.
- Table 2 illustrates the composition of whey protein concentrate powder obtained using the principles described above.
- thermolabile proteins such as serum albumin and to avoid substantial loss of the glutamylcysteine groups in the whey proteins.
- PROTEIN (%) 77.5 77.04 78.08 a Lactalbumin (%) 23.68 23.85 22.20 ⁇ Lactoglobulin (%) 59.90 60.37 61.40
- the process of this invention therefore provides a practical procedure for making undenatured whey protein concentrate. Furthermore it has the advantage of using a by-product of cheese production which is otherwise considered to be a troublesome waste product, and a potential pollutant. It should solve what was until now a continuing financial problem for the dairy industry responsible for the disposal of this major water pollutant. In conclusion, it is the objective of this invention to preserve intact the conformation of the labile whey proteins in the W.P.C. This objective of leniency is obtained through several inter-dependent steps involving temperature, ions content, ultrafiltration flux and drying techniques.
