Description

FIELD OF THE INVENTION

The invention pertains to a pourable fat which is low in saturated fatty acids and also has low or is substantially free of trans fatty acids.

BACKGROUND OF THE INVENTION

Fluidized fat, also known as a liquid butter alternative, is pourable and useful for broiling, pan frying, grilling and sauteing, to name a few kitchen applications. Conventionally, these compositions are made from partially hydrogenated oils with added fully hydrogenated oils to meet certain fat solids profile. Thus, as such they are relatively high in both saturated fatty acids and trans fatty acids.

Therefore, it is an object of the present invention to provide a fat product in a pourable form which is both low in saturated fatty acids and is low or contains substantially no trans fatty acids with an ambient shelf life of at least 12 months. Optionally, the Fluidized fat products may also contain color, flavorings, salt, essential oils, oleo and aqua resins, natural extractives in conjunction with herb and spices, cheeses and other seasonings, lecithin and antioxidants.

SUMMARY OF THE INVENTION

The invention concerns a pourable fat composition which has a long shelf life and which comprises:

(a) 50 to 99 wt. % of a fat blend comprising

(i) 90-99.8 wt. % of unhydrogenated liquid oil; (ii) 10-0.2 wt. % of fully hydrogenated fat having an iodine value of less than about 10 and that has the ability to form a crystal network in the end product. The fully hydrogenated fat preferably with less than 5 iodine value, being hardened canola oil or high erucic rapeseed oil, soybean oil, cotton seed oil and fish oil.

(b) up to 1.0% of lecithin, preferably acylated lecithin;

(c) 0-10 wt. % of microcrystalline edible salt;

(d) 0-45 wt. % of flavors and colors, herb and spices, nuts and seeds, sugar and starches and flavorings, essential oils, oleo and aqua resins, natural extractives in conjunction with herb and spices, cheeses and other seasonings,

(e) up to 5 wt. % of an anti-oxidant added to protect the flavor of the oil.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

The fat blend is present in the compositions in an amount of 50-99 wt. %, preferably 65-99.8 wt. %, more preferably 90-99.8 wt. %. The fat blend comprises 90-99.8 wt. % of an unhydrogenated liquid oil and 10-0.2 wt. % of a fully hydrogenated fat component. The oil displays a solid fat content (NMR pulse, not stab) of less than 10% at 20.degree. C., preferably less than 5% at 20.degree. C.

The liquid oil used in the invention is preferably selected from the group consisting of: canola oil, high oleic canola, sunflower oil, high oleic sunflower oil, safflower oil, high oleic safflower oil, soybean oil, corn oil, olive oil, cotton seed oil, peanut oil, arachidic oil, olein fractions of natural oils, such as palm oil olein, medium chain triglycerides MCT-oils. The liquid oil is unhydrogenated. Preferably the amount of liquid oil is 93-99, most preferably 94-96 wt. % in the fat blend.

The liquid oil displays a low saturated fatty acids content. Preferably canola, sunflower corn, peanut, olive, soybean and safflower oil are used. More preferably canola, safflower and sunflower oils are used which have less than 11% saturated fatty acids. Unhydrogenated refined liquid oil is used.

The hydrogenated or hard fat component of these blends must have the ability to form a fat crystal network in the compositions. This requirement is essential in order to produce stable compositions. Also in order to suspend the optional ingredients, for such ingredients to remain in suspension a fat crystal network is needed.

Examples of suitable fully hydrogenated fats are hardened sunflower seed oil, hardened soybean oil, hardened palm oil, hardened canola, hardened cottonseed, hardened fish oil hardened rapeseed oil or mixtures thereof. The best results were obtained, by using hard fats, having an I.V.<10, preferably less than about 5, most preferably less than about 2 I.V. Most preferred hard fats are fully hardened canola oil, soy oil, cottonseed and low erucic rapeseed oil.

The pourable character of the compositions is obtained because the fat blend of the liquid oil and the hard fat component have an apparent viscosity of 700-2500 cps after storage for 7 days at room temperature 20-22.degree. C. The viscosity is measured by using Brookfield Viscometer Model # LVTD with spindle #3 and/or 4 at 60 RPM. The Brookfield reading is multiplied by a factor of 20 (if Spindle # 3 is used) and factor of 100 (if spindle # 4 is used) to obtain cps.

Antioxidants are used to protect flavorings. Preferably 200 ppm of TBHQ.

Process

The invention is prepared by a process wherein

(i) the oil blend is prepared by dissolving all oil soluble ingredients such as fully hydrogenated fat, antioxidants and emulsifiers such as lecithin etc. into heated unhydrogenated oil to form a uniform mixture. (ii) the resulting mixture is heated to a temperature of at least 70.degree. C. to dissolve substantially all the fat crystals. (iii) the heated mix (ii) is cooled to a temperature of about 20.degree. C. to form a cooled mixture containing some fat crystals; and (iv) the cooled mixture is gently mixed to form a network of fat crystals.

Optionally colors, flavorings, microcrystalline salt, essential oils, oleo and aqua resins, natural extractives in conjunction with herb and spices, cheeses and other seasonings are added to the formed fat network. It was found, that the best ambient stability was obtained if dried and oil soluble extract of spices are used.

The mixing according to step (iv) can be performed by any conventional mixing technique except it has to be gentle mixing to form a network. The cooling step was preferably in a scraped surface heat exchanger.

The following nonlimiting examples illustrate the invention.

EXAMPLE 1

2840 g. of unhydrogenated canola oil, 135 g. of fully hydrogenated canola stearine and 3 grams of lecithin were mixed and heated to 70.degree. C. The mixture was cooled and passed through a votator then mixed gently to form the crystal network until a viscosity of 1200 cps was obtained. 21 grams microcrystalline salt, B carotene and flavors were then added and the product was collected.
