Range Of Aseptically Produced Infant Foods Having Low Concentrations Of Undesired By-products And Methods For Making The Same

Abstract

A range of infant food products wherein each product in the range includes minimal levels of undesired by-products produced during processing as indicated by less than about 15 micrograms furan per kg food product.

Description

BACKGROUND OF THE INVENTION

[0001] 1. Field of the Invention

[0002] The present invention relates generally to infant food products and particularly to infant food products having low concentrations of undesired by-products produced during processing or packaging.

[0003] 2. Description of Related Art

[0004] It is known that processing of food products can produce undesirable by-products. For example, when food products are roasted, the roasting process can lead to the production of undesirable acrylamide. Alternatively, when food products are subjected to cooking, for example in cans and jars, this can lead to production of undesirable furan.

[0005] Furan, like acrylamide, is a substance which is generated naturally during the heating of food products during processing. It is not a synthetic substance added to the food as an ingredient, but occurs in food products as a result of processing.

[0006] High concentrations of furan have been shown to be genotoxic and in animal experiments carcinogenic.

[0007] Furan is listed in the Department of Health and Human Services list of carcinogens, and considered as possibly carcinogenic by the International Agency for Research on Cancer, based on studies in the laboratory animals at high exposures. Thus, high concentrations of furan are undesirable in food products.

[0008] Furan can be generated by heat processing of foods comprising polyunsaturated fatty acids (PUFAs), ascorbic acid (vitamin C), .beta.-carotene, sugars and amino acids.

SUMMARY OF THE INVENTION

[0009] It is, therefore, an object of the invention to provide a new range of infant food products that includes a reduced level of undesirable by-products. The level of undesirable by-products can be measured, for example, by reference to furan concentration in a food product.

[0010] These and other objects are addressed in one aspect of the invention by providing a range of infant food products wherein each product in the range has less than about 15 micrograms furan per kg food product. The resulting range of infant food products has the advantage that each food product in the range has minimal concentrations of undesirable by products produced during processing. In various embodiments, the components include substantially no furan (eg less than about 5 micrograms/kg furan in the food product) or no furan.

[0011] In a further aspect, the invention provides a feeding regime for meeting the nutritional needs of an infant during different stages of development, the regime comprising administering to an infant a range of food products according to the invention.

[0012] In a further aspect, the invention provides use of a range of food products according to the invention in the manufacture of one or more medicaments for the prevention or treatment of a nutritionally related disorder.

[0013] In another aspect, the invention provides a method of preventing or treating a nutritionally related disorder, comprising administering a range of food products according to the invention.

[0014] The nutritionally related disease is optionally selected from obesity, malnutrition, diabetes and heart disease.

[0015] Other and further objects, features, and advantages of the present invention will be readily apparent to those skilled in the art.

Test Results and Data

[0103] Furan formation was studied in aqueous model systems at pH7 and pH4 following heat treatment at 121.degree. C. for 25 minutes. The results are shown in FIGS. 2 and 3. The results show that at pH7, the concentration of PUFAs show the highest impact on furan development after heat treatment at 121.degree. C. for 25 minutes.

[0104] At pH 4, ascorbic acid plays an important role as a precursor of furan after heat treatment at 121.degree. C. for 25 minutes, but it can be seen that PUFAs still show the highest impact on furan development.

[0105] Two further studies were carried out. The first study was carried out to investigate the amount of furan formation relative to the addition of ascorbic acid and LC-PUFA derived from fish oil and the results are shown in FIG. 4. The second study was carried out to investigate the concentration of furan formation relative to the sterilization conditions used for processing of the food product and the results are shown in FIGS. 5 and 6. In FIG. 5 the results are shown with regard to a vegetable food product comprising carrot. In FIG. 6 the results are shown with regard to a savoury food product comprising cod and mixed vegetables. It can be seen that there is about 2 micrograms of furan per kg food product produced as a by-product following processing according to the invention.

[0106] The results clearly show that increased levels of fish oil and vitamin C lead to larger levels of furan production. In addition, sterilization of the food product by retorting lead to remarkably larger levels of furan production in the food product compared to sterilization by UHT treatment at F0=100, F0=15 and F0=8. (F0 is a well known indicator of sterility--the F0 value is a known measure of the time required to kill clostridium botulinum bacteria). Indeed, it can clearly be seen that UHT sterilization minimizes the formation of furan by a factor of 2.5 to 5 compared to traditional retorting under normal sterilization conditions. In addition, remarkably, while amplified sterilization conditions resulted in a linear increase of Furan formation in products processed by retorting, furan formation as a result of UHT treatment remained almost constant.

[0107] In the specification, there have been disclosed typical preferred embodiments of the invention and, although specific terms are employed, they are used in a generic and descriptive sense only and not for purposes of limitation, the scope of the invention being set forth in the following claims. Obviously many modifications and variations of the present invention are possible in light of the above teachings. It is therefore to be understood that within the scope of the appended claims the invention may be practiced otherwise than as specifically described.
