Definitions
- the present invention relates to shrimp with low cholesterol content, especially for use in the food industry directed to the consumer. More specifically, the invention relates to the problem of producing food with a reduced amount of cholesterol, motivated by the result of numerous investigations, which have suggested that cholesterol ingested in the diet constitutes a risk factor in the development of coronary heart disease. (Grundy et al., 1982).
- a second object of this invention is to provide a process for the production of shrimp with a low cholesterol content, which would enter the market as a product of high added value from the shrimp sector, given the growing demand for foods with low cholesterol content .
- the fluid acquires unique thermodynamic and transport properties, that is, its density is relatively high, similar to that of a liquid, which gives it a good solvent power, while its relatively low viscosity and relatively high diffusivity Like those of a gas, they provide a great capacity for penetration into the sample. Because of this, the rapidity of mass transfer of solutes is greater within a supercritical fluid than within a liquid (Rizvi et al., 1986). Manipulating the operating conditions, the fluid Supercritical has the ability to selectively extract one or more specific components, such as fats, oils, cholesterol, ketones, aldehydes and esters, leaving proteins, sugars and other carbohydrates intact (Dziezak, 1986).
- the main supercritical solvent used in the food industry is carbon dioxide, as it has important advantages over other solvents. This is: it is not flammable, it is not corrosive, it is not toxic, it does not pollute the environment, it does not leave solvent residues, its cost is low and its critical temperature (31, 1 ° C) is relatively low, which makes it suitable in the extraction of thermally unstable materials.
- ESC supercritical extraction technique
- some processes have been established with the supercritical extraction technique (ESC), with a view to reducing the fat and cholesterol content in foods of animal origin.
- ESC supercritical extraction technique
- a process for the production of shrimp reduced in cholesterol content has not been proposed by applying ESC, or by any other type of processing. Cully, et al. (1991), Application Patent of the German Federal Republic
- McLachlan, et al. (1990), EPO356165 established a procedure for the extraction of sterols and / or lipid components (for example, cholesterol and fats) from protein foods such as meat, using fluids in a subcritical and supercritical state, with an initial treatment of the product in which all free water is removed, but not the bound water in its entirety, which results in an intermediate moisture product. Moisture removal is carried out by lyophilization until the sample is reduced to a moisture content of 30-55%. For the removal of lipids, supercritical carbon dioxide was used, immediately separating the cholesterol from the carbon dioxide-fat fraction by means of a selective adsorbent. Subsequently the product is reconstituted with water and grease.
- sterols and / or lipid components for example, cholesterol and fats
- shrimp species and sizes were included that have a high level of acceptability among consumers because of their taste and size, even though this means a higher amount of cholesterol to be removed since the cholesterol naturally present in them is higher compared with some other species, and even when its large size represents a greater difficulty its removal.
- the present invention relates to shrimp with low cholesterol content, referring to all species of the subgenus Litopenaeus (L occidentalis, L. schmitti, L. setiferus, L. stylirostris, L vannamei).
- the procedure is applicable to shrimp of other genera, sub genera and species in their different sizes.
- only a little standardization routine is required to the proposed procedure, without thereby detracting from the invention. It is important to note that the above consists in the modification to a greater or lesser volume of supercritical fluid, according to the greater or lesser content to be removed from cholesterol, as well as to a slight variation in temperature for lower or higher cholesterol contents.
- a second aspect of the invention involves the process for obtaining said shrimp.
- shrimp without head and shell are used as raw material.
- the proposed procedure consists in initially subjecting shrimp with the characteristics mentioned to a dehydration stage.
- Dehydrated shrimp immediately go to the next stage of processing, which involves the extraction of cholesterol from shrimp with a solvent that is highly selective for lipids at a given temperature and pressure.
- a supercritical extraction equipment is used and carbon dioxide is used as an extractor fluid.
- Dehydrated shrimp are placed in the equipment extraction unit. Liquid carbon dioxide flows from the storage tank and is passed through the compressor of the extractor equipment to bring it to a supercritical pressure of 100 to 400 bar.
- the resulting gas enters the extractor unit provided with a heating jacket that allows to maintain the extraction temperature in a range of 30 to 60 ° C, and passes through the shrimp sample by dragging the cholesterol with it.
- This process can be applied to shrimp of different species and sizes, varying only the operating conditions.
- the gas discharged together with the extract pass through an expansion valve. It is then when the separation of the gas is carried out by precipitation, releasing the extract, since a variation of the pressure at supercritical conditions implies a reduction in density and as a consequence a decrease in its dissolution capacity.
- Dehydrated shrimp with a lower cholesterol content are reconstituted using water, in a ratio of 1 to 10 mL per gram of shrimp. Rehydration is performed by placing them in a vacuum chamber at room temperature for a period of 1 to 5 hours. The rehydrated shrimp is cooked with steam for presentation to the consumer in its original form.
- the final product obtained in this process constitutes a non-existent food until before the present invention and meets the nutritional labeling requirements established for a food of reduced content and low cholesterol, according to the guidelines stipulated by the US Food and Drug Administration (FDA) According to them, a product considered reduced in cholesterol must contain 75% or less cholesterol than the reference food and a low cholesterol product must contain 2 to 20 mg of cholesterol per edible portion (FDA, 1986). In these values a standard error of 20% is allowed, so a cholesterol content of less than 24 mg per edible portion is acceptable for low cholesterol foods (FDA, 1990).
- FDA US Food and Drug Administration
- the final presentation of the product object of this invention is another of the novel elements of this application, which Allows you to retain your original geometric shape.
- the shrimp still has the characteristics own sensory nature.
- a sensory acceptance analysis was applied in which dehydrated shrimp was evaluated and with cholesterol removed by ESC, which was rehydrated and cooked. Said shrimp corresponded to the category of low cholesterol shrimp (less than 24 mg / edible portion).
- the test was applied to a panel of 30 untrained subjects. The attributes of: smell, taste, texture, color and overall appearance were evaluated. The evaluation scale was 7 points: -3 to +3.
- the Kolmogorov-Smirnov nonparametric test was used in the statistical analysis.
- the raw material used is blue shrimp (Litopenaeus stylirostris) and white shrimp (Litopenae ⁇ s vannamei), size 16/20, without head, which is kept frozen (-18 ° C) until processing.
- the raw material is defrosted and husked manually or mechanically.
- the shrimp is frozen individually at -40 ° C for a period of 4 hours, in a fast freezing chamber. Subsequently, the shrimp undergoes a lyophilization process until it reaches a 1 to 5% moisture content.
- a tray freeze-drying equipment is used. Frozen shrimp are placed in the freeze dryer chamber, which is initially programmed at a temperature of -40 ° C. The interior and surface temperature of shrimp is monitored with the help of thermocouples. A Once the equipment reaches a vacuum of 0.1 mm Hg, the following conditions program is started: Temperature Time ° C hs 29 1
- the time will depend on the vacuum value that is presented, which should not exceed 0.2 mm Hg. b The time will depend on when the shrimp reach a maximum temperature of 5 to 10 ° C. c Depending on when the shrimp's internal temperature equals their surface temperature.
- Cholesterol extraction is carried out with a selective solvent (carbon dioxide) for cholesterol, at a supercritical pressure and temperature of 310 bar and 37 ° C.
- a supercritical carbon dioxide extraction equipment is used.
- the extraction system consists of four basic components: a compressor or solvent pump, an extractor, a pressure / temperature control system and a separator.
- the lyophilized shrimp is placed in the extraction unit of the system.
- Carbon dioxide flows from the storage tank and is passed through the compressor of the extractor equipment to bring it to the supercritical pressure of 310 bar.
- the resulting gas enters the extractor unit provided with a heating jacket, which allows the operating temperature to be maintained at 37 ° C.
- the gas carries with it the extract consisting mainly of cholesterol.
- the volume of carbon dioxide is measured in a volume counter.
- the speed of the extractor fluid through the system is maintained at 5.5 - 6.2 L / min, even when other flow rates can be used.
- Carbon dioxide, as well as the extract is passed through an expansion valve in order to be separated.
- the sample of shrimp previously lyophilized and subjected to ESC is rehydrated at room temperature, following a ratio of 5 mL of purified water per gram of shrimp. Rehydration is carried out in a vacuum atmosphere (533.4 mm Hg). For this, the shrimp are placed horizontally in a container with water, and vacuum is applied for 1 hour. At the end of this time the shrimp is turned leaving the other side exposed and rehydrated to the same conditions for 1 more hour.
- the shrimp subjected to ESC and rehydrated in this way is placed in a steam container for a period of 6 minutes, less time than required for fresh shrimp.
- the shrimp rehydrated or rehydrated and cooked, is vacuum packed and placed in a rapid freezing chamber for individual freezing a -
- V Volume of carbon dioxide (L)
- FIG. 2 A response surface plot illustrating the final regression equation obtained in this experiment is presented in Fig. 2.
- the graph shown in Fig. 3 shows the amount of cholesterol remaining in the shrimp (dry base), as a function of temperature at different volumes of carbon dioxide and at a pressure of 345 bar. It can be seen that at this pressure, the amount of remaining cholesterol decreases as the volume of carbon dioxide increases with respect to temperature.
- the effect of temperature on solubility is somewhat complex because of two concurrent effects; one effect tends to increase solubility with an increase in temperature, while the other tends to decrease it.
