THERMALLY PROCESSED SHELF-STABLE DAIRY-BASED COMPOSITION AND METHODS FOR MAKING SAME
The present disclosure provides dairy compositions comprising particulates and having good color, flavor, and texture after thermal processing. In a general embodiment, the compositions include particulates such as fruits and/or grains, and the compositions are thermally processed and shelf-stable. Methods for reducing or inhibiting browning of dairy-based compositions are also provided. The methods include, for example, thermally processing a dairy composition including particulates such as fruits and/or grains at a temperature that is less than about 240° F. The compositions and methods of the present disclosure provide several advantages including, for example, the reduction or avoidance of degradation/browning of the compositions during processing and storage.
1 . A method for reducing or inhibiting browning of a thermally processed, shelf-stable dairy-based composition, the method comprising:
providing a dairy-based composition comprising milk protein concentrate and a reduced amount of reducing sugars; and
thermally processing the dairy-based composition at a temperature that is less than about 240° F. and for an amount of time from about 5 to about 40 minutes.
2 . The method according to claim 1 , wherein thermally processed is aseptic processing.
3 . The method according to claim 1 , wherein thermally processed is retort processing.
4 . The method according to claim 1 , wherein the dairy-based composition is substantially free of reducing sugars.
5 . The method according to claim 1 , wherein the dairy-based composition comprises only a naturally occurring amount of reducing sugars.
6 . The method according to claim 1 , wherein the dairy-based composition comprises only a naturally occurring amount of lactose.
7 . The method according to claim 1 , wherein the dairy-based composition includes particulates.
8 . The method according to claim 1 , wherein the dairy-based composition includes particulates selected from the group consisting of fruit, fruit pieces, grains, nuts, and combinations thereof.
9 . The method according to claim 8 , wherein the grains are selected from the group consisting of amaranth, barley, buckwheat, corn, cornmeal, popcorn, millet, oats, oatmeal, quinoa, rice, rye, sorghum, teff, triticale, wheat, wild rice, and combinations thereof.
10 . The method according to claim 8 , wherein the grains comprise oats and barley.
11 . The method according to claim 8 , wherein the fruit is selected from the group consisting of apples, bananas, coconut, pear, apricot, peach, nectarines, plum, cherry, blackberry, raspberry, mulberry, strawberry, cranberry, blueberry, grapes, grapefruit, kiwi, rhubarb, papaya, melon, watermelon, pomegranate, lemon, lime, mandarin, orange, tangerine, guava, mango, pineapple, tomato, and combinations thereof.
12 . The method according to claim 7 , wherein particle integrity in the thermally processed dairy-based composition is improved.
13 . The method according to claim 1 , wherein the dairy-based composition comprises at least one ingredient selected from the group consisting of a low fat yogurt, pectin, sugar, starch, and combinations thereof.
14 . The method according to claim 1 , wherein the dairy-based composition comprises a pH at or below about 4.2.
15 . The method according to claim 1 , wherein the thermal processing occurs at a temperature from about 190° F. to about 240° F.
16 . The method according to claim 1 , wherein the thermal processing occurs at a temperature from about 190° F. to about 210° F. and for an amount of time from about 10 to about 40 minutes.
17 . The method according to claim 1 , wherein the thermal processing occurs at a temperature from about 200° F. to about 220° F. and for an amount of time from about 10 to about 25 minutes.
18 . The method according to claim 1 , wherein the thermal processing occurs at a temperature from about 210° F. to about 230° F. and for an amount of time from about 5 to about 20 minutes.
19 . The method according to claim 1 , wherein the dairy-based composition is a yogurt composition.
20 . The method according to claim 1 , wherein the dairy-based composition after thermal processing has good: color, flavor, texture, or combinations thereof.
