Description

STARCH COMPRISING AND READY-TO-SERVE AMBIENT STABLE FRUIT- BASED COMPOSITION

FIELD OF THE INVENTION

The present invention is directed to a ready-to-serve and ambient stable fruit-based composition . More particularly, the invention is directed to a ready-to-serve and ambient stable fruit -based composition having a fork-mashed texture . The fruit-based composition of this invention is low in fat , starch and insoluble fiber comprising, and suitable to be a filling, dip, sauce , spread, dressing or the like . The fruit-based composition of this invention can be prepared from ripened and/or over ripened fruit , and is ambient stable after opening . Moreover, the ready-to- serve and ambient stable fruit-based composition of this invention surprisingly maintains its fork-mashed appearance for the duration of its shelf-life , notwithstanding the fact that the same can be made free of fork-mashed fruit .

BACKGROUND OF THE INVENTION

Consumption of nutrients , like antioxidants and folic acid, which are abundant in fruits and vegetables, has been linked to a lower incidence of cardiovascular disease . Moreover, it is well settled that eating fruits high in soluble fiber can reduce cholesterol levels , which protects against atherosclerosis .

Other advantages of having a diet high in fruit include better athletic performances, reduced risk of developing chronic bronchitis , a lowered risk of getting most common cancers (including breast cancer) , as well as a lowered risk of getting cataracts . Additionally, fruits , like avocado, contain protein, vitamin E, vitamin C, and beta- carotene and are often linked to stroke prevention .

While food products comprising fruits and vegetables have been linked to health benefits in humans , such products are often difficult to prepare for sale in commerce . This is true because the quality of food products comprising fruit often deteriorates (e . g . , loses texture , browns , darkens, grows mold and/or loses flavor) due to enzymatic reactions within the food product . These reactions result in a product that has a short shelf-life and does not have an appealing look, taste or texture after spending a limited period of time in conventional commercial channels .

Known techniques have been used to inhibit the deterioration of food products comprising fruits and/or vegetables . These techniques include pasteurization of the fruit , high vacuum processing for removing oxygen, and chemically treating the fruit with sulfiting agents before making the food product . The aforementioned techniques do not completely eliminate , for example , browning and darkening in food products comprising fruit , and such techniques have adverse effects on the flavor, aroma, texture and nutritional value of the fruits and vegetables treated, as well as the food products prepared therefrom.

It is of increasing interest to develop a ready-to-serve and ambient stable fruit-based composition that does not , for example, lose flavor, brown, darken and lose its mash texture , and that has an extended shelf-life at ambient temperature . This invention, therefore, is directed to a ready-to-serve and ambient stable fruit-based composition that , preferably, has not been subj ected to chemical treatment , high vacuum processing and temperatures over about 80⁰C . The ready-to-serve and ambient stable fruit- based composition of this invention is low in fat , comprises starch and insoluble fiber, and is suitable to be a filling, dip, sauce, spread, dressing or the like . Moreover, the ready-to-serve and ambient stable fruit-based composition of this invention can be prepared from under ripe, ripened and/or over-ripened fruit , and is ambient stable after opening, and able to maintain its fork-mashed appearance for the duration of its shelf-life . Such a fruit-based composition has substantially the same visual , texture , aroma and taste attributes of a fork-mashed fruit- based composition made on demand from freshly picked fruits , notwithstanding the fact that the same is substantially free of (preferably free of) fork-mashed fruit .

Ambient stable also means that the fruit-based composition displays no browning, darkening, flavor change, texture change or separation (i . e . , creaming) for at least about eight (8) weeks after opening when kept covered and refrigerated at about 5⁰C . Ripened fruit , as used herein, means a fruit that is sufficiently advanced and mature . Over ripe fruit means fruit that is softer and often sweeter than ripe fruit . Ready-to-serve means flavored with optional additives and ready for consumption by a consumer .

Chemically treating means reacting with and not merely mixing fruit with commonly employed food grade acids . Fork- mashed means a soft pulpy appearance and texture with particles having a size from about 1.0 to about 5.0 millimeters in diameter, mash potato-like and free of starch breakdown due to the presence of enzymes , like amylase .

The ready-to- serve and ambient stable fruit-based composition of this invention is typically prepared by making the acidified fruit-based composition where oil may be added to fruit flesh prior to adding insoluble fiber . In a preferred embodiment , oil is added to the insoluble fibers prior to adding fruit flesh. Also, oil may be added to the insoluble fibers before or after water has been combined with the fibers . Emulsifier is also added to the insoluble fibers either before , with or after the addition of oil , but preferably before the addition of oil . Fat soluble additives (like flavors) can be added to the oil phase and water soluble additives like sugar, salt and preservatives can be added to the aqueous phase (along with builders) before the two phases are mixed to form a pre- emulsion or coarse emulsion . In an especially preferred embodiment , the oil with fat soluble additives is mixed with insoluble fibers , water and water soluble additives to produce a coarse emulsion.

When the desired optional additives (e . g . , j alapeno peppers , tomatillo) are subsequently combined with the emulsion having smaller oil droplet sizes , the resulting composition is a ready-to-eat fruit-based composition whereby the same is most preferably, a ready-to-eat guacamole composition . In an especially preferred embodiment , the ready-to-eat fruit-based composition is heated, for example , in heat exchangers like the Votators made available from Cherry Burrell . The ready-to-eat fruit- based composition (when having a pH greater than about 3.3 , and optionally, when having a pH less than about 3.3 ) is heated for about 30.0 seconds to about 8.0 minutes , but preferably for about 2.0 minutes to about 4.0 minutes , including all ranges subsumed therein to render the same ambient stable . In a preferred embodiment , the temperature in the heat exchanger is from about 65⁰C to a temperature that does not exceed about 80⁰C . In a most preferred embodiment , the heat exchanger is a scrape surface type, and the heating occurs for about 2.0 to about 4.0 minutes at a temperature from about 73.0⁰C to a temperature that does not exceed about 80.0⁰C . In another most preferred embodiment , the pH of the ready-to-eat and ambient stable fruit-based composition is from about 2.75 to about 3.75.

It is also within the scope of this invention to heat the fruit not being supplied as optional additive in lieu of the ready-to-eat fruit composition when the resulting ready-to-eat and ambient stable fruit composition has pH above about 3.3. Such heating of the fruit is optional when the pH of the resulting ready-to-eat and ambient stable fruit-based composition is less than about 3.3 , where , again, starch is preferably added after heat treating when the starch is an acetylated distarch adipate .

Sachets are preferred for food service solutions , and a glass jar is preferred for domestic use . In a preferred embodiment the packaging is filled cold, and most preferably, ultra clean or aseptically.

The viscosity of the ready-to-serve and ambient stable fruit-based composition of this invention is typically greater than about 3 , 000 and less than about 150 , 000 centipoise . When a sauce or pourable dressing is , for example, the desired composition, the viscosity of the composition is preferably from about 4 , 000 to about 10 , 000 centipoise, and most preferably, from about 4 , 350 to about 6 , 000 centipoise .

When the desired ready-to-serve and ambient stable fruit- based composition is , for example , a filling, dip, spread or spoonable dressing, the viscosity of the food product is preferably from about 12 , 000 to about 120 , 000 centipoise, and most preferably, from about 16 , 000 to about 80 , 000 centipoise , whereby the viscosity of the composition is measured on a Haake Rheometer (Rotovisco RV20) at room temperature using a set of concentric cylinders (or bob-in- cup) with a 1 mm gap, the bob having a diameter of 1.0 cm and length of 1.0 cm. The inner cylinder or bob starts rotating from 0 shear and ramps up to a shear rate of 134 sec^"1 in 542 sec . By way of comparison, the viscosity values refer to the shear rate of 10 sec^"1.

Fiber phase 60 .0 Oil phase 18 .9 Avocado flesh 20 .0 Hydrochloric acid o .; 24 Water Balance Ingredients of the oil and fiber phases were combined and mixed under moderate shear at atmospheric pressure and ambient temperature in a conventional mixer to produce a coarse emulsion. The coarse emulsion was then subj ected to a homogenizer (e . g . , APV Gaulin Homogenizer) pressurized to about 250 bar . The resulting emulsion was combined with the ingredients in the final mix to produce an acidified avocado-based composition having a fork-mashed texture . The same was then subj ected to a votator for about three (3) minutes at 75°C to produce an ambient stable , acidified avocado-based composition .

Example 2

Ambient stable , acidified avocado-based compositions having a fork-mashed texture were made in a manner similar to the one described in Example 1 except that oxidised starch (at 3.5%) was used in lieu of potato starch. The oxidized starch was added as part of the final mix and not the fiber phase , and the citrus fiber level was reduced to 1.0% .

Example 3

Ambient stable , acidified avocado-based compositions having a fork-mashed texture were made in a manner similar to the one described in Example 2 except that the starch used was an acetylated distarch adipate in lieu of oxidized starch . The starch was added and mixed in to the composition after votating . Example 4

The ambient stable, acidified avocado-based compositions of Examples 1-3 were compared to conventional avocado-based compositions not subjected to the heat and acid treatments as defined in this invention and not comprising the fiber and starch combination as described herein. Surprisingly, after about eight (8) weeks , the former looked fresh, was not rancid or brown and tasted substantially the same as freshly made fork-mashed avocado-base . The latter was not edible .

Moreover, the latter, even when made with fork-mashed fruit , did not maintain its fork-mashed texture as did the acidified avocado-based composition of this invention.
