Fruit snack with probiotics and method of manufacturing a fruit snack with probiotics
A fruit snack with probiotics that is stable at room temperature is manufactured by combining various ingredients including fruit juices/purees to produce a slurry and cooking the slurry to produce a center that contains a high moisture content. The fruit snack center is covered with a barrier layer which in turn is covered by an outer layer that contains heat sensitive ingredients, such as probiotic cultures. The barrier layer substantially prevents migration of moisture from the center to the outer layer, and the fruit snack is cooled prior to applying the outer layer to minimize damage/harm to the heat sensitive ingredients. In addition to including probiotic cultures and being stable at room temperature, the fruit snack has other desirable characteristics including a chewy soft texture and fruit-flavorings, and may be manufactured using traditional processes.
1. A process of manufacturing a food product, comprising the steps of:
combining a plurality of ingredients to produce a slurry;
cooking the slurry to produce a center for the food product;
applying a barrier layer to the center of the food product;
applying an outer layer over the barrier layer applied to the center of the food product, the outer layer containing at least one of L. acidophilus and L. casei ; and
allowing the center of the food product to cool to substantially room temperature prior to applying the outer layer.
2. The process of claim 1 , wherein the applied barrier and outer layers represent by weight between 5% and 80% of the food product.
3. The process of claim 1 , wherein the step of applying an outer layer comprises applying an outer layer of at least one of yogurt, dark chocolate and milk chocolate, the outer layer including the heat sensitive components.
4. The process of claim 1 , wherein the barrier layer includes vegetable gums adapted to prevent migration of moisture from the center to the outer layer.
5. The process of claim 4 , wherein the vegetable gums are selected from a group consisting of CMC, xanthan gum, gum Arabic, and carageenan gum.
6. The process of claim 1 , wherein the barrier layer is a water soluble protein.
7. The process of claim 6 , wherein the water soluble protein is selected from a group consisting of zein, egg albumin and milk-albumin.
8. The process of claim 1 , wherein the step of combining comprises combining at least one of fruit puree and fruit juice with another ingredient to produce the slurry.
9. The process of claim 1 , wherein the step of combining comprises combining sweetening agents, flavoring agents, water, acidulants, and at least one of fruit purees and juices.
10. The process of claim 1 , wherein the step of cooking comprises cooking the slurry to a temperature exceeding 212° F.
11. The process of claim 1 , wherein the step of applying a barrier layer comprises applying a barrier layer of yogurt coating.
12. The process of claim 1 , wherein the step of allowing the center of the food product to cool to substantially room temperature is carried out prior to the step of applying the barrier layer to the center of the food product.
13. A food product, comprising:
a center having a moisture content;
a barrier layer disposed over the center, the barrier layer adapted to substantially prevent migration of moisture from the center of the food product; and
an outer layer disposed over the barrier layer, the outer layer containing at least one of L. acidophilus and L. casei.
14. The food product of claim 13 , wherein the barrier and outer layers represent by weight between 5% and 80% of the food product.
15. The food product of claim 13 , wherein the outer layer includes at least one of yogurt, dark chocolate and milk chocolate.
16. The food product of claim 13 , wherein the barrier layer includes vegetable gums adapted to prevent migration of moisture from the center to the outer layer.
17. The food product of claim 16 , wherein the vegetable gums are selected from a group consisting of CMC, xanthan gum, gum Arabic, and carageenan gum.
18. The food product of claim 13 , wherein the barrier layer is a water soluble protein.
19. The food product of claim 13 , wherein the water soluble protein is selected from a group consisting of zein, egg albumin and milk-albumin.
20. The food product of claim 13 , wherein the center includes sweetening agents, flavoring agents, water, acidulants, and at least one of fruit purees and juices.
21. The food product of claim 13 , wherein the barrier layer includes yogurt coating.
22. The process of claim 1 , wherein the at least one of L. acidophilus and L. casei are provided at a concentration of about 50 billion cells per gram.
23. The food product of claim 13 , wherein the at least one of L. acidophilus and L. casei are provided at a concentration of about 50 billion cells per gram.
