Abstract

A suspended nutrition composition includes a foamed material, a colloid layer and a nutrient. The foamed material having a plurality of pores includes a starch, a biodegradable polyester and a plasticizer. The pores are formed by bubbles produced from a physical foaming agent. The colloid layer covers a surface of the foamed material. The nutrient is dispersed in the foamed material.

First claim

What is claimed is:

1. A suspended nutrition composition comprising:
a foamed material comprising a starch, a biodegradable polyester and a plasticizer, the foamed material having a plurality of pores, wherein the pores are formed by bubbles produced from a physical foaming agent, and wherein the content of the starch is 65 wt % to 75 wt %, the content of the biodegradable polyester is 15 wt % to 25 wt %, the content of the plasticizer is 8 wt % to 13 wt %, and the content of the physical foaming agent is 0.5 wt % to 5 wt %, which are based on a total weight of the foamed material;
a colloid layer covering a surface of the foamed material; and
a nutrient dispersed in the foamed material and the colloid layer, wherein the content of the nutrient dispersed in the foamed material is greater than the content of the nutrient dispersed in the colloid layer.

2. The suspended nutrition composition as recited in claim 1 , wherein the suspended nutrition composition has a density of less than 1 g/cm 3 .

3. The suspended nutrition composition as recited in claim 1 , wherein the starch comprises corn starch, cassava or potato.

4. The suspended nutrition composition as recited in claim 1 , wherein the biodegradable polyester comprises a poly(butylene succinate) (PBS) or a poly lactic acid (PLA).

5. The suspended nutrition composition as recited in claim 1 , wherein the plasticizer comprises a mixture of glycerol and water or a polyalcohol.

6. The suspended nutrition composition as recited in claim 1 , wherein the colloid layer comprises a natural biocolloid or a chemosynthetic colloid.

7. The suspended nutrition composition as recited in claim 6 , wherein the natural biocolloid comprises agar, xanthan gum, shellac, guar gum, gamma-polyglutamic acid, pectin or sodium alginate.

8. The suspended nutrition composition as recited in claim 6 , wherein the chemosynthetic colloid comprises a poly(lactic-co-glycolic acid) (PLGA).

9. The suspended nutrition composition as recited in claim 1 , wherein the nutrient comprises potassium hydrogen phosphate (KH 2 PO 4 ), magnesium sulfate (MgSO 4 .7H 2 O), manganese sulfate (MnSO 4 .4H 2 O), boric acid (H 3 BO 3 ), sodium tetraborate (Na 2 B 4 O 7 .10H 2 O), copper sulfate (CuSO 4 .5H 2 O), zinc sulfate (ZnSO 4 .7H 2 O), ammonium heptamolybdate ((NH 4 ) 6 Mo 7 O 24 .4H 2 O), urea (CO(NH 2 ) 2 ) or any combination thereof.

10. The suspended nutrition composition as recited in claim 1 , wherein the nutrient comprises calcium nitrate (Ca(NO 3 ) 2 .4H 2 O), calcium chloride (CaCl 2 ), ferric-ethylenediaminetetraacetic acid (Fe-EDTA), potassium nitrate (KNO 3 ) or any combination thereof.

11. The suspended nutrition composition as recited in claim 1 , wherein the physical foaming agent comprises urea (CO(NH 2 ) 2 ), sodium hydrogen carbonate (NaHCO 3 ), ammonium bicarbonate (NH 4 HCO 3 ) or calcium carbonate (CaCO 3 ).
