POWDERED NUTRITIONAL FORMULATIONS INCLUDING
SPRAY-DRIED PLANT PROTEIN
TECHNICAL FIELD OF THE DISCLOSURE
The present disclosure relates to powdered nutritional formulations including a
dryblended plant protein. At least a portion of the dryblended plant protein has been spray dried
prior to being dryblended into the powdered nutritional formulation.
BACKGROUND OF THE DISCLOSURE
Adult, pediatric, and infant manufactured nutritional liquids and powders comprising a
targeted selection of nutritional ingredients are well known and widely available, some of which
may provide a sole source of nutrition, while others may provide a supplemental source. These
nutritionals include powders that can be reconstituted with water or other aqueous liquid, as well
as concentrated and ready-to-drink nutritional liquids. These powdered nutritional formulations
and liquids are especially useful when formulated with selected nutritional ingredients, such as
protein.
Powdered nutritional formulations are especially popular for providing nutrition and their
use continues to increase around the world. These powdered nutritional formulations are
typically prepared by making at least two separate slurries that are first blended together. One
slurry may be an aqueous-based slurry and one may be an oil-based slurry. After blending, the
resulting mixture is generally heat-treated, standardized, heat-treated a second time, spray-dried,
agglomerated and packaged. With this manufacturing process, a substantial amount of energy is
required to spray-dry the product and the drying process significantly increases manufacturing
time. Additionally, the spray driers may require frequent cleaning to reduce build up of powder
in the dryers.
In order to increase throughput and decrease costs, attempts have been made to dryblend
certain components into conventionally prepared base powders such that a reduced amount of
spray-drying is required during manufacturing. Individual components such as vitamins,
minerals, carbohydrates, polyunsaturated fatty acids and proteins have been dryblended into base
powders with mixed results. In many cases, reconstitution has been an issue such that preparing
a commercially satisfactory beverage is not possible.
There is therefore a need for dryblended powdered nutritional formulations comprising
proteins, including plant proteins, that have improved reconstitution characteristics including
improved mouthfeel and improved viscosity.
SUMMARY OF THE DISCLOSURE
One embodiment of the present disclosure is directed to a powdered nutritional
formulation comprising a dryblended plant protein. At least a portion of the dryblended plant
protein is spray-dried plant protein.
Another embodiment of the present disclosure is directed to a powdered nutritional
formulation comprising at least one milk protein and at least one spray-dried plant protein. The
spray-dried plant protein comprises up to about 50 wt.% of the total protein in the powdered
nutritional formulation.
Another embodiment of present disclosure is directed to a method of preparing a
dryblended powdered nutritional formulation including a spray-dried plant protein. The method
comprises preparing a base powder including at least one of a fat, carbohydrate, and protein, and
dryblending into the base powder a spray-dried plant protein.
It has been found that when plant proteins, such as pea proteins, are dryblended into
nutritional bases powders, even at very low concentrations, when the dryblended nutritional
powder is reconstituted, it has an undesirable, gritty mouthfeel that may feel slimy. Also, it has
been found that over a short period of time, the reconstituted liquid may develop an undesirably
high viscosity that is not commercially acceptable.
It has now been discovered that the undesirable, gritty mouthfeel of the reconstituted
powder resulting from the dryblending of a plant protein into a powdered nutritional formulation
can be minimized or eliminated by first spray-drying the plant protein prior to dryblending into
the powdered nutritional formulation. It has also been found that spray-drying at least a portion
of the plant protein prior to dryblending into the powdered nutritional formulation significantly
reduces or eliminates the issue of an increasing viscosity over a short period of time upon the
powdered nutritional formulation being reconstituted with water.

Methods of Manufacture
Nutritional base powders (into which at least a portion of the spray-dried plant protein is
dryblended) may be prepared by dryblending all of the ingredients together to form a
dryblended base powder into which at least a portion of the spray-dried plant protein is
dryblended. Alternatively, the nutritional base powder (into which at least a portion of the spraydried
plant protein is dry-blended) may be prepared using conventional wet processes which
generally include utilizing two or more slurries that are ultimately mixed together, treated, and
dried.
At least a portion of the plant protein present in the dry-blended powdered nutritional
formulation is plant protein that has been spray-dried prior to being dry-blended with the
nutritional base powder. The remainder of the plant protein, if any, that is not spray-dried may
be included in the nutritional base powder described above. In a preferred embodiment, 100% of
the plant protein present in the powdered nutritional formulation is spray-dried by conventional
methods prior to being dryblended or otherwise introduced into the nutritional base powder
described above to form the dryblended powdered nutritional formulation.
In some embodiments, the plant protein may be high temperature short time (HTST)
pasteurized prior to being spray-dried. Specifically, the plant protein may be added to water and
allowed to hydrate until suspended; the water may or may not be heated. This protein-in-water
slurry is then HTST processed prior to being spray-dried. Optionally, the plant protein may be
conventionally homogenized after the HTST treatment and prior to the spray-drying. The spraydrying
step is a conventional spray-drying step that is conducted at conventional well known
temperatures and times to produce a spray-dried plant protein.
The manufacturing processes for the dryblended powdered nutritional formulations
including spray-dried plant proteins may be carried out in ways other than those set forth herein
without departing from the spirit and scope of the present disclosure. The present embodiments
are, therefore, to be considered in all respects illustrative and not restrictive and that all changes
and equivalents also come within the description of the present disclosure.
Methods of Use
The dry-blended powdered nutritional formulations described herein and including spraydried
plant protein, when reconstituted, provide an improved mouthfeel over a reconstituted
liquid formed from a powder comprising a plant protein that has not been spray-dried. In
addition, the dryblended powdered nutritional formulations as described herein provide a means
for producing a reconstituted liquid including a plant protein that does not have a viscosity that
increases over a short period of time to form a gel-like product.
An individual desirably consumes at least one serving of the reconstituted powdered
nutritional formulation daily, and in some embodiments, may consume two, three, or even more
servings per day. Each serving is desirably administered as a single undivided dose, although the
serving may also be divided into two or more partial or divided servings to be taken at two or
more times during the day. The methods of the present disclosure include continuous day after
day administration, as well as periodic or limited administration, although continuous day after
day administration is generally desirable. The dryblended powdered nutritional formulations
may be reconstituted for use in infants, children, and adults.

Example 11
In this example, two identical samples of commercially available pea protein are
subjected to two different spray-drying processes and the resulting spray-dried pea proteins are
then mixed with whey protein, reconstituted, and evaluated for mouthfeel and color. A control
sample of identical commercially available pea protein not subjected to a spray-drying process is
utilized as a control.
Commercially available pea protein (Roquette NUTRALYS® S85F) is added to water at
about 10 wt.% total solids and allowed to hydrate until suspended. This protein-in-water (PIW)
slurry is then split into two batches with the first batch (Sample 1) being spray-dried without
further treatment (Cyclone configuration, nozzle size of 0.018, swirl chamber 4, and pressure of
about 2500 psi). The second batch (Sample 2) is high temperature short time (HTST) processed
with a 16 second hold at a temperature of 165-185°F and homogenized at a pressure of 3000-
5000 psig prior to being sent to the spray-drier under identical conditions to Sample 1.
No issues are encountered during the process of drying. About 24 pounds of powder are
collected (about 12 pounds from each batch). The control and Sample 1 and Sample 2 are
separately dryblended with instantized whey protein, at a 50:50 weight ratio and evaluated for
mouthfeel improvement. A significant color and mouthfeel is seen in both Sample 1 and Sample
2 as compared to the control. Both Sample 1 and Sample 2 had virtually no gritty or slimy
mouthfeel and had good light color. The control had a substantial gritty mouthfeel along with a
slimy mouthfeel.
