FOOD PRODUCTS THAT CONTAIN LOW FAT, CONCENTRATED HEMP PROTEIN, AND RELATED METHODS
Described are food compositions including doughs, extrudates, and finished puffed food compositions derived therefrom. The food compositions contain hemp protein, non-hemp protein, and starch. Such a food composition contains at least 40 weight percent total protein and less than 10 weight percent total fat, based on total weight of the food composition on a dry basis. Advantageously, the finished food product has a surprisingly crunchy texture. Additionally, the finished food product has improved storage stability as compared to compositions having greater levels of hemp fat.
1 . A food composition comprising:
starch,
at least 40 weight percent protein, the protein comprising hemp protein and non-hemp protein, and
less than 10 weight percent total fat,
wherein the weight percentages of protein and total fat are based on total weight of the food composition on a dry basis.
2 . The food composition of claim 1 wherein the food composition is an extruded food composition having a density that is lower than a density of a comparable food composition, the comparable food composition having a same weight percentage of total protein as the food composition but being devoid of hemp protein.
3 . The food composition of claim 1 comprising:
from 5 to 40 weight percent starch,
from 40 to 80 weight percent total protein, and
from 1 to 5 weight percent total fat,
based on the total weight of the food composition on a dry basis.
4 . The food composition of claim 1 comprising:
from 0 to 7 weight percent non-hemp fat, and
from 0.1 to 5 weight percent hemp fat,
based on the total weight of the food composition on a dry basis.
5 . The food composition of claim 1 wherein the hemp protein is part of a hemp protein ingredient, the hemp protein ingredient comprising at least 70 weight percent hemp protein and not more than 10 weight percent hemp fat, based on total weight of the hemp protein ingredient on a dry basis.
6 . The food composition of claim 1 wherein the hemp protein is part of a hemp protein ingredient, wherein the hemp protein ingredient comprises:
from 60 to 95 weight percent hemp protein,
less than 6 weight percent fat, and
less than 10 weight percent water,
based on total weight of the hemp protein ingredient on a dry basis.
7 . The food composition of claim 1 wherein the non-hemp protein is part of a non-hemp protein ingredient, the non-hemp protein ingredient comprising at least 60 weight percent non-hemp protein and not more than 10 weight percent non-hemp fat, based on total weight of the non-hemp protein ingredient on a dry basis.
8 . The food composition of claim 1 wherein the non-hemp protein comprises at least one of soy protein, pea protein, rice protein, legume protein, sacha inchi protein, algal protein, and mycoprotein.
9 . The food composition of claim 8 wherein the non-hemp protein comprises pea protein.
10 . The food composition of claim 1 wherein the food composition is a puffed food composition having a water content below 5 weight percent based on the total weight of the food composition.
11 . The food composition of claim 1 wherein the food composition is an extruded food composition having a density that is below 0.3 grams per cubic centimeter.
12 . The food composition of claim 1 wherein the food composition is an extruded food composition having a density that is below 0.25 grams per cubic centimeter.
13 . The food composition of claim 1 wherein the food composition contains less than 1 weight percent total gluten based on the total weight of the food composition on a dry basis.
14 . A method of preparing an expanded food composition, the method comprising:
combining ingredients to prepare a dough that comprises:
starch;
at least 40 weight percent protein on a dry basis, the protein comprising hemp protein and non-hemp protein; and
less than 10 weight percent total fat on a dry basis; and
extruding the dough to form an expanded food composition.
15 . The method of claim 14 further comprising drying the expanded food composition.
16 . The method of claim 15 wherein, after drying, the expanded food composition has a water content below 5 weight percent based on total weight of the expanded food composition.
17 . The method of claim 14 wherein the expanded food composition has a density that is below 0.3 grams per cubic centimeter.
18 . The method of claim 14 wherein the hemp protein is part of a hemp protein ingredient, the hemp protein ingredient comprising at least 70 weight percent hemp protein and not more than 10 weight percent hemp fat, based on total weight of the hemp protein ingredient on a dry basis.
19 . The method of claim 14 wherein the hemp protein is part of a hemp protein ingredient, wherein the hemp protein ingredient comprises:
from 60 to 95 weight percent hemp protein,
less than 6 weight percent fat, and
less than 10 weight percent water,
based on total weight of the hemp protein ingredient on a dry basis.
20 . The method of claim 14 wherein the non-hemp protein comprises at least one of pea protein, rice protein, and legume protein.
