ABSTRACT:
BACKGROUND OF THE INVENTION
Edible fat based, flavoured fat systems suitable for use in baked goods and snacks are known from U.S. Pat. No. 5,431,945 or U.S. Pat. No. 4,356,643 or U.S. Pat. No. 5,447,735. From these documents butter based flakes are disclosed in U.S. '945. These flakes are free of sugar and contain a lot of predried butter fat and high contents of dried milk solids. Particulars of the fats that can be applied are not given, all that is said about the nature of the fats, that can be applied is that they are related to butter fat. According to U.S. '643 cheese based flakes can be obtained along lines that are very similar to the lines set out above for U.S. '945. These flakes contain high levels of dried cheese solids while the fats that can be applied are the same or very similar to the fats according to above U.S. '945. According to U.S. '735 cinnamon based flakes can be obtained that contain large amounts of granulated sugar while the fat is again a butter fat or a fat closely related to butter fat. Therefore fat flakes that contain high amounts of the healthy polyunsaturated fatty acids such as DHA or EPA are not disclosed in the prior art. It would be very beneficial if such products could be made, because this will mean that the flakes can be used to administer these very healthy fatty acids to the consumer via the flakes, when applied in bakery products. However a problem was anticipated before hand because it was found by the inventors that blends of vegetable fat and fish oil are not storage stable and develop an off taste and/or fishy smell when stored at room temperature within 2 weeks. As for the fat flakes a period between production and end use of 4 or more weeks will not be unusual the fat flakes should be stable for at least such a period when stored at room temperature. Therefore it was expected that fish oils could not be used in the fat flakes. Unexpectedly we found that fish oils could be applied successfully in the flakes under the condition of the invention resulting in products that were storage stable for at least 4 weeks and even for more than 3 months.
SUMMARY OF THE INVENTION
Our invention therefore concerns in the first instant the finding of fats that overcome the problems of the prior art. In particular we found novel edible fat based, flavoured fat systems suitable for use in baked goods and snacks comprising:
i) 0 to 2 wt % of moisture;
ii) 25 to 90 wt %, preferably 30 to 70 wt % of a bakery compatible fat composition, comprising:
(1) a vegetable fat or a derivative therefrom having an N20 (unstabilised by NMR-pulse)of more than 50, preferably more than 65 and
(2) 5-40 wt %, preferably 15 to 35 wt % of a fish oil composition, containing w-3 fatty acids in such quantities that the total w-3 content of total flavoured fat system ranges from 0.1 to 20 wt %, preferably 2 to 10 wt % (i.e. on total flake)
iii) 0 to 15 wt % of a flavouring system
iv) 0 to 40 wt % of sugar
v) 0 to 60 wt %, preferably 5 to 40 wt % of a filler material other than sugar
vi) 0 to 50 wt %, preferably 5 to 40 wt % of a health component, and which edible fat based system has a particle size between 0.05 mm and 2.5 cm.
DESCRIPTION OF THE PREFERRED EMBODIMENTS
The flakes so obtained displayed excellent properties like hardness and oral mouthfeel. It was unexpected that the use of fish oil having a relatively low N25 values still have such a good hardness because it should have been expected that these fats would result in low hardness values and thus in insufficient textural properties.
As fish oil any known commercial fish oil, such as Menhaden fish oil could be applied. However we prefer to use the fish concentrates as disclosed in our WO 97/19601. These fish oils contain high levels of polyunsaturated fatty acids, in particular high levels of DHA and EPA while the ratio of DHA and EPA is relatively low i.e. from 0.5 to 6.0 meaning that these fats can be relatively rich in either EPA or DHA. Thus we have a preference for edible fat based fat system according to the invention wherein the w-3 fatty acids are mainly, preferably for more than 40%, EPA and DHA, and are preferably present in a ratio DHA/EPA of 0.5-6.0.
The other fat component of the fat blend, i.e. the fat with an N20 of more than 50 can be selected from any natural fat or fraction therefrom, optionally after hardening meeting this N20 value. Examples of such fats are: cocoa butter; cocoa butter equivalents such as palm mid fractions, shea stearin and illipe; palm stearin; hardened liquid oils, such as hardened sunflower oil, hardened rape seed oil, hardened bean oil.
Flavouring systems that can be applied in our novel flakes can be selected from the group consisting of the natural flavour components from fruit, like lemon, oranges, strawberries, raspberries, blueberries, goose berries, redberries, blackberries, apples, pears, peaches, apricots, cherries, from nuts, like walnuts, hazelnuts, macadamia's, groundnuts, from herbs or spices like cinnamon, ginger, nutmeg, cloves, allspice, ethnic flavours (Mediterranean, Cajun), from maple sugar or dehydrated maple syrup, from garlic or onions, from butter or cheese, from savory flavours such as savory culinary aids, from synthetic flavour components imitating above natural flavours, and from mixtures thereof. These flavouring systems can be applied in any form, including forms that are excluded by U.S. '735, wherein the flavour must be a particulated solid. The flavours that can be applied can be used in a form selected from the group consisting of: finely devided solid flavours; finely divided solid or liquid flavours on a solid carrier, liquid flavours and microcapsules containing a solid, or liquid, or gaseous flavour.
The fats that lead to the beneficial results indicated above are different from or dissimilar to butter fat and can be selected from the group consisting of: natural or hardened glycerides based on C12+ fatty acids such as cocoa butter, soybean oil, cotton seed oil, groundnut oil, rapeseed oil, sunflower oil, corn oil, palm oil, shea oil, illipe fat, palm kernel oil, coconut oil or fractions or blends thereof and preferably having a content of less than 5 wt % trans acids
The filler is used to structure the flakes while not attributing to much to its caloric content. Suitable filler materials are dried particulated ingredients preferably selected from the group consisting of flour, skim milk powders, butter milk powder, starches, polysaccharides other than sugar, gums, whey powder, cellulose and hydrocolloids.
As the consumers are nowadays more and more interested in products that are healthy and in particular in foods that contain health components, the most preferred fats that can be applied are essentially free of trans fatty acids, in particular these fats contain less than 5 wt % of these trans acids.
This thus means that in particular partially hardened fats i.e. fats with a relatively high trans fatty acid content, which are known to give structuring to food products but that are considered as less healthy fats, are less preferred in these foods. It was unexpected that such health foods could still be obtained without the need to use such partially hardened fats.
Because of the fats that we apply in our novel flakes it is possible now to make healthy food products that contain a healthy fat component. Simultaneously we also can incorporate a health component in the flakes in an amount that is effective to benefit from its presence in the flakes. The health component remains homogeneously distributed in the flakes and can be selected from olives, grapes, grape fruit, pumpkins, paprika, garlic, tomatoes, oranges, lemons, berries, nuts, in particular in the form of particulated fruit skins of olives, grapes, grape fruit, tomatoes, paprika, or particulated garlic, onions, herbs or spices.
In addition to these components also other health components can be present such as vitamins and minerals. Herefore all well known vitamins and minerals can be applied. Some of these components are present in m
