ABSTRACT:
FIELD OF THE INVENTION
The present invention relates to the field of broths or stocks, and more particularly to a broth or stock comprising minced bone pieces with extract, and the production methods involved therein. The bones are preferably from chicken.
BACKGROUND OF THE INVENTION
In hotels, restaurants, Chinese restaurants, and Chinese noodle shops, in order to use bones as ingredients for soup stock, one has had to use fresh ingredients, and those ingredients have had to be frozen for both storage and distribution. In order to make soup from bones, the production process has required complicated work involving heat adjustment, scum removal, filtration, clarifying the liquid, and boiling it down to the proper concentration. Depending on the experience of those preparing the soup, their differing levels of technical skill have had a significant impact on product quality, making it difficult to maintain product uniformity. Furthermore, though there are products on the market containing finely chopped, frozen bones filled in a porous bag, the problem with these products is that as a result of being frozen as loosely-separated, fine pieces, they end up being extracted in an extremely short period of time. As a result, the extractable portion ends up being extracted in 1-2 hours when making the soup, and it has not been possible to make soup in a stock pot with a consistent quality that could be maintained throughout the business hours of the restaurants, hotels, etc. Furthermore, because of the size of the bones, only a set amount can be put into the large pot, and it has been difficult to make thick soups characteristic of certain types of cuisines, for example Chinese noodle shops. Artificial seasonings have sometimes been added to enhance the flavor, however, this reduces the versatility of the product by limiting seasoning options, and these practices have impaired consumer acceptance.
Up until the present, there have not been any natural food bases that can be stored and distributed at room temperature, which can deliver a soup whose concentration can be adjusted as desired, and is capable of maintaining a consistent quality over a relatively long period of time, such as the daily business hours of restaurants, hotels, etc.
SUMMARY OF THE INVENTION
One object of the present invention is to provide flexibility for storage and distribution conditions of a soup base, by offering a product that can be stored and distributed at room temperature. In addition, the present invention offers a natural food base that is preferably solidified into block form through the coagulation of the ingredients, based on the minced bone pieces and the retort sterilization of the raw ingredients, and which can be readily used in its block form to make soup with a consistent quality and adjustable concentration and extraction time.
The principal ingredient employed in the present invention is preferably chicken bones, but is not limited to broiler chickens, leftover bones from chickens used for their meat, and breeding hens, but can also be in the form of whole chickens, including their meat, or chicken meat itself. Meat and/or bones from pork, etc. may also be used. The extract from meat and/or bone can be in liquid, powdered, or other form.
Extract can be made, for example from the meat and/or bones, which are extracted with hot water and concentrated to a desired strength. The extraction may be performed on an industrial scale. The extract may for example, be condensed and made into a highly concentrated extract. Alternatively, it may be made into powdered extract through, for example, spray-drying methods. Commercially available concentrated meat extract products may be employed.
Next, the chicken bones are minced. Preferably, a chopper is used to mince the chicken bones into 3 mm diameter pieces. Extract is added to the minced bones and the ingredients mixed together thoroughly. When the bones are minced into smaller pieces, the pieces stick together closely and the soup stock is extracted at a slower speed of extraction. On the other hand, when the bones are minced into larger pieces, the bone pieces stick together loosely, and the soup stock is extracted at a faster speed of extraction. Also, the concentration can be adjusted with the addition of the extract, thereby enabling the concentration of the soup to be adjusted to fit various types of cuisine.
The mixed product is minced bone and meat and/or bone extract
1
, filled into retort pouches
3
whose openings are then sealed. These sealed pouches
3
are put into a retort sterilization machine to kill bacteria and microorganisms. During this time, the mixed product will coagulate under the heat, and solidify. Tests conducted on broiler chicken bones, leftover chicken bones from chicken used for meat, and breeding hen bones, all yield substantially similar results.
The minced bones and extract may be placed in a water-permeable, sealed container
2
, which is placed inside the sealed pouch
3
for retort processing. This water permeable, sealed container
2
provides mechanical protection for the coagulated mass, and retains insoluble components during extraction of the soup or stock.
According to the present invention, the coagulated mass provides an extended release of soluble matter into the soup or stock, while initially releasing a significant portion to speed initial preparation. As compared to traditional soup-making, therefore, the present invention provides a faster initial availability of soup, while allowing a stock pot to be refilled with water over the course of several hours, as volume is depleted while generally maintaining the quality of the soup for the duration. Traditionally, with known minced bone preparations, adding water to replace withdrawn volume would result in dilution of the soup, whereas according to the present invention, the dissolved solids are replaced during the course of a shift.
In order to monitor the dissolution of solids, and therefore the density of the soup, a hydrometer
4
may be used. This measures the specific gravity of the liquid, to quantify dissolved solids. According to the present invention, a disposable hydrometer
4
may be included in the retort pouch
3
, which would thus be provided in a sterile condition along with the soup base. Such a hydrometer is formed, for example, by a sealed air chamber with a weight at one end and a measuring scale at the other. Increased dissolved solids in the soup will cause greater density, and therefore the hydrometer will be more buoyant. The height of the scale above the fluid level therefore may be calibrated in terms of the specific gravity of the soup. This hydrometer
4
may then be used to determine an appropriate volume of replacement water or readiness of the soup or stock, and to prevent over-dilution when the soup base is exhausted.
Of course, any type of known hydrometer may be employed, or the replacement volume determined empirically, based on a predetermined formula, or using other known means.
While a preferred method for providing delayed or controlled release of meat and/or bone extract is to provide a coagulated mass of bone fragments and meat and/or bone extract, other known delayed or controlled release techniques may be used, for example encapsulation, gel matrix, erosion matrices, and other techniques. Where other controlled release technologies are employed, a different method of sterilization may be used, for example ozone or hydrogen peroxide, radiation, or other known non-thermal sterilization. However, thermal coagulation of the minced bones and extract is a preferred method of production.
A preferred embodiment of the invention provides a natural food base in the form of a soup stock from poultry and other animal meat and/or bones, made from a solidified mixture of minced meat and/or bones as the main ingredient with added meat and/or bone extract. The soup stock's taste, aroma, and extraction time may be adjusted through the alteration of the ratio of added extract. The product's retort sterilization enables i
