Description
[0001] This application claims priority to U.S. Provisional Application
No. 60/620,846, filed Oct. 21, 2004, herein incorporated by reference
in its entirety.
BACKGROUND OF THE INVENTION
[0002] The present invention is directed to baked food products
comprising peanut flour, and is illustratively directed to crackers
made with peanut flour.
[0003] Previous work (Zenere, "Physicochemical and Sensory
Properties of a Chip-type Snack Food Based on Defatted Peanut and
Soy Flour," Ph.D. Dissertation, University of Georgia, 2003)
showed that baked peanut chips could be processed from partially
defatted flour milled from cold-pressed peanuts (with testa). However,
because of the composition of the flour (40-44% protein, 10-14%
fat) and high level of usage (greater than 50% of total ingredients
in some formulations), some of the baked products were undesirably
hard and tended to pack in the teeth when chewed. Initial sensory
evaluation tests showed potentially high consumer acceptance of
such a snack food, particularly if the texture could be made softer
and more cracker-like.
SUMMARY OF THE INVENTION
[0004] Baked products have been developed by incorporating peanut
flour in the recipe. In one aspect of this invention, a baked food
product is provided comprising a flour mixture comprising peanut
flour, baking powder, a fat, a milk product, and egg. Illustratively,
the peanut flour is light roast peanut flour that has been partially
defatted to 10 to 14%, and the milk product is selected from the
group consisting of whole milk, reduced fat milk, and non-fat dry
milk, and the fat is butter, margarine, vegetable oil, hydrogenated
vegetable oil, partially hydrogenated vegetable oil, and/or vegetable
shortening. If non-fat dry milk is used, water may be added. In
another illustrative embodiment, the flour mixture comprises peanut
flour, wheat flour, and rice flour. Additionally, one or more seasonings
may be added. Illustratively, the baked food product has the shape
and texture of a cracker.
[0005] In another aspect of this invention, methods of preparing
a baked food product are provided, comprising the steps of preparing
a dough comprising wheat flour, salt, baking powder, a fat, a milk
product, egg, and peanut flour; rolling the dough; and baking the
dough. Optionally, the dough is cut into cracker size prior to the
baking step. The baking step optionally includes baking in an impingement
oven, baking at 200.degree. C., and/or baking for a sufficient time
period to obtain a generally uniform crispy texture.
[0006] Additional features of the present invention will become
apparent to those skilled in the art upon consideration of the following
detailed description of preferred embodiments exemplifying the best
mode of carrying out the invention as presently perceived.
DETAILED DESCRIPTION
[0007] Various compositions were used in developing a peanut flour
cracker. Commercial light roast peanut flour with 50% protein and
12% fat was used in a basic cracker formula (wheat flour, shortening,
egg, milk, baking powder, salt) at levels ranging from 7 to 42%,
with and without rice flour. While vegetable shortening is used,
it is understood that other fats such as butter, margarine, vegetable
oil, hydrogenated vegetable oil, and partially hydrogenated vegetable
oil may be used instead. Also, while whole milk is used in the illustrative
examples, it is understood that reduced fat milk, evaporated milk,
or dry milk may be used instead, and water content adjusted accordingly.
Ten illustrative flour mixtures based on a three-component (wheat,
rice, peanut) constrained simplex lattice design were investigated.
Process conditions (mixing, sheeting, cutting, baking) were established
in preliminary trials. All 10 formulas had instrumental color and
texture measurements that fell within the range of values determined
for five commercial crackers (Saltines, Munchems, Wheatables, Wheatsworth,
Wheat Thins). All of the illustrative crackers contained more nitrogen
(1.74 to 3.87%) and thus more protein than the commercial crackers
(1.24 to 1.68% nitrogen). Not surprisingly, formulas #3 and #10
which contained the highest levels of peanut flour (42 and 30.33%,
respectively) had the highest nitrogen content (3.87 and 3.15%,
respectively). The flour mixture with the highest level of peanut
flour that also exhibited the best overall dough handling characteristics
was formula #6 (58% wheat, 17.5% rice, 24.5% peanut). This mixture
was then used as a control for further development to incorporate
seasonings that could enhance the flavor of the basic cracker. The
flavor variations and levels of use were: garlic powder, 2%; Cajun
salt, 2.4%; cheddar cheese, 10.5% and cheddar cheese/cayenne, 10.4%.
All variations and the control were formulated to contain 1% salt.
Consumers (n=75) recruited from the local community (Griffin, Ga.)
evaluated the sensory quality of the crackers. Crackers made with
cheddar cheese or cheddar cheese/cayenne pepper received the highest
hedonic ratings (9-point scale) for appearance (7.0=like moderately),
color (7.1-7.2), aroma (6.3-6.5=like slightly), flavor (6.4-6.5),
texture (6.6-6.7) and overall liking (6.4-6.7). Consumers (67%)
were concerned about the nutritional quality of the crackers they
consumed and 71% were willing to pay more for crackers with enhanced
nutritional quality. These findings indicate that processing of
a peanut flour chip or cracker that is acceptable to consumers is
feasible and has potential for expanding the use of peanuts.
EXAMPLE I
Peanut Flour Cracker Formulations
[0008] Commercial testa-free, partially defatted peanut flour (50%
protein, 12% fat) obtained from Golden Peanut Co., Alpharetta, Ga.,
was used in each of the formulations. Light, medium, and dark-roast
flours were evaluated in preliminary trials to select the flour
with the most desirable peanut flavor intensity after baking. Medium
and dark roast flours produced crackers that had over roasted, bitter
flavors. Therefore, only light roast peanut flour was used for subsequent
baking trials. A food processor (GE 4-speed, model 106622F, Wal-Mart,
Bentonville, Ark.) was used to mix and knead the dough ingredients
under controlled conditions of time and speed. Two-stage sheeting
(Anets SDR-4 dough roller, Anetsberger Brothers, Northbrook, Ill.)
to reduce the dough to a uniform thickness was employed. Crackers
were cut with a standard strip cutter (Moline Machinery, Duluth,
Minn.). Preliminary baking trials found that impingement oven baking
at 200.degree. C. for 3 minutes produced uniformly baked crackers.
A three component (wheat, rice, peanut flours) constrained simplex
lattice design (Table 1) was used to evaluate the cracker-making
performance of flour mixtures and to identify mixtures that had
acceptable dough handling as well as desirable end product characteristics.
It is understood that peanut flour does not contain sufficient quantities
of gluten. Therefore, wheat flour is illustratively added to the
flour mixture. Rice flour is added in several of the illustrative
examples. It is understood that other types flour may be added as
well. Objective quality measurements (color, texture, proximate
composition) were determined on 10 illustrative formulations plus
5 types of commercial crackers. Consumer acceptability of the most
promising formulations was also determined. TABLE-US-00001 TABLE

Dough Handling Characteristics
[0009] Dough handling characteristics of 10 illustrative cracker
formulations plus 100% control were evaluated. The results are summarized
in Table 2. Three mixtures (#1, #2 and #6) produced doughs that
were easy to handle (roll, cut and sheet). Two mixtures (#3, #9)
did not form a dough ball and required manual shaping. Sticky or
crumbly doughs that were difficult to handle were produced by formulas
#4, #9 and #10. Formulas #5, #7 and #10 were difficult to transfer
after cutting to the baking pan. TABLE-US-00002 TABLE 2 Dough handling

Color Measurements
[0010] Color measurements (L*=lightness, a*=redness to greenness,
b*=yellowness to blueness) were determined in triplicate using a
Gardner Colorimeter XL845 (Pacific Scientific, Bethesda, MD) calibrated
with a standard reference tile (L*=82.57, a*=-2.01 and b*=27.87).
Psychometric color terms of chroma [(a*.sup.2+b*.sup.2).sup.1/2],
hue angle [tan.sup.-1(b*/a*)] and total color difference, .DELTA.E
[(L*-L* reference).sup.2+(a*-a* reference).sup.2+(b*-b* reference).sup.2].sup.1/2
were computed for all samples.
[0011] Instrumental measurements of the color of the crackers are
shown in Table 3. For commercial crackers, the degree of lightness
(L*) ranged from 66.6 to 84.3 on a scale of 0 (black) to 100 (white);
degree of redness (a*) ranged from 0.01 to 7.0 and yellowness (b*)
from 23.0 to 30.1. Control crackers (100% wheat flour) had the highest
value for L* (81.2) and the lowest for redness (a*=0.8) and yellowness
(b*=24.9) compared to the illustrative crackers. Crackers made from
formula #3 contained the highest level of peanut flour (42%) and
were darker (lowest L*=70.9), more red (a*=6.1) and more yellow
(b*=33.2) compared to 100% wheat flour crackers and the other 9
illustrative crackers. Although there was variation in color among
illustrative formulations, color values of crackers containing mixtures
of wheat, rice, and peanut flours fell within the color range of
the commercial crackers. TABLE-US-00003 TABLE 3 Color characteristics

EXAMPLE IV
Texture
[0012] The textural quality of the crackers was evaluated in triplicate
using the Instron universal testing machine (model 1122, Instron
Corp., Canton, Mass.) equipped with a Kramer cell attached to a
500 kg load cell. Maximum force (N) and energy (J) required to crush
.about.10 grams (5 crackers) were calculated from the force-deformation
curve.
[0013] Instrumental measures of the texture of the crackers are
shown in Table 4. The amount of force required to crush the commercial
crackers ranged from 1870.8 to 4108.3 Newtons (N); the amount of
energy ranged from 8.6 to 18.7 Joules (J). Control crackers (100%
wheat flour) required 2394 N and 6.8 J to crush. Force values for
the illustrative crackers ranged from 2000.3 to 2735.2 N and were
within the range found for commercial crackers. Energy values for
the illustrative crackers ranged from 4.8 to 10.7 J. Young's modulus,
a measure of elasticity, ranged from 157.8 to 421.8 Mpa for the
illustrative crackers and from 148.0 to 386.4 Mpa for commercial
crackers. Overall, illustrative crackers had similar textural characteristics
to those of commercial crackers. TABLE-US-00004 TABLE 4 Texture

EXAMPLE V
Composition
[0014] The proximate composition of crackers was determined. Moisture
content was determined on 5 g ground samples by drying overnight
at 70.degree. C. under 25 mmHg. Ash content was determined on 2
g ground samples by heating overnight in a muffle furnace at 525.degree.
C. Dried samples remaining from moisture analysis were used for
fat analysis. Fat analysis was determined by overnight solvent extraction
(about 16-18 hr) with petroleum ether using a Goldfisch apparatus
(Labconco, Kansas City, Mo.). Nitrogen content was determined on
0.2 g ground samples using the Dumas combustion method (LECO analyzer,
model 602-600, Warrendale, Pa.). The proximate composition of five
flavor variations of the most promising formulation was determined
on a fresh weight basis (as consumed) by Silliker Laboratories,
Stone Mountain, Ga.
[0015] The proximate composition of the illustrative crackers is
shown in Table 5. Moisture content of the 10 peanut flour mixtures
ranged from 4.29 to 7.38%; commercial crackers contained 5.45 to
12.81% moisture. Ash content was similar for all crackers, ranging
from 3.12 to 4.27% in the illustrative formulas and from 2.10 to
4.49% in the commercial products. Crude fat content ranged from
15.79 to 19.54% in the illustrative products and from 9.21 to 18.8%
in the commercial crackers. Among the 10 illustrative formulas,
those having the highest amount of peanut flour, #3 (42%) and #10
(30.33%), had the highest nitrogen content (3.87 and 3.15%, respectively).
Not surprisingly, all of the illustrative crackers contained more
nitrogen (1.74 to 3.87%) and thus more protein than the commercial
crackers (1.24 to 1.68% nitrogen) due to the inclusion of peanut
as an ingredient. TABLE-US-00005 TABLE 5 Proximate composition (wet

Sensory Attributes
[0016] A consumer acceptability test of five flavor variations
of the most promising formulation (control, 1% salt; cheddar cheese,
10.5%; Cajun salt, 2.4%; cheddar cheese/cayenne pepper, 10.4%; garlic
powder, 2.0%) of peanut flour crackers was conducted. Consumers
(n=75) were recruited from the local community (Griffin, Ga.) and
were screened to (1) be at least 18 years old, (2) eat crackers
on a regular basis and (3) not be allergic to peanuts, wheat, milk,
salt, rice, egg, garlic, cheese, or Cajun seasoning. Demographic
characteristics of the participants were as follows: ages ranged
from 18-75 with 24% being 55-64 years of age; 80% were female; 77%
were white; 59% were married; 61% had completed high school, vocational
school, or some college; 43% were employed full time; and 53% had
incomes .ltoreq.$30,000.
[0017] Sensory evaluation was conducted in the climate-controlled
sensory evaluation laboratory of the Department of Food Science
and Technology, University of Georgia--Griffin Campus. When the
panelists arrived, they completed a consent form and received instructions
on the conduct of the evaluation. Panelists evaluated samples in
partitioned booths illuminated with incandescent lighting, using
a 9-point hedonic scale (1=dislike extremely, 5=neither like nor
dislike, 9=like extremely). Samples coded with 3-digit numbers were
presented monadically and in a randomized order. Panelists cleansed
their palates between samples with water and unsalted crackers.
After the evaluation, panelists completed an exit questionnaire
pertaining to cracker purchasing, consumption and handling practices
and their willingness to purchase nutrition-enhanced crackers.
[0018] The General Linear Model (GLM) procedure was used to analyze
all data (SAS Institute, 2001). Mean separation tests were performed
by the least significant difference (LSD) test (.alpha.=0.05).
[0019] All 10 illustrative formulas produced crackers with acceptable
sensory attributes. The flour mixture with the highest level of
peanut flour that also exhibited the best overall dough handling
characteristics was formula #6 (58% wheat, 17.5% rice, 24.5% peanut).
Therefore, formula #6 was used for further development to evaluate
various seasonings for flavor enhancement. Hereafter, formula #6
is referred to as the control.
[0020] The mean ratings for consumer acceptance of the control
and four flavor variations (cheddar cheese, Cajun salt, cheddar
cheese and cayenne, and garlic powder) of crackers are shown in
Table 6. Preliminary trials established the appropriate level of
each seasoning; all samples were formulated to contain 1.0% salt.
Crackers made with cheddar cheese or cheddar cheese/cayenne pepper
received the highest ratings for appearance (7.0=like moderately),
color (7.1-7.2), aroma (6.3-6.5=like slightly), flavor (6.4-6.5),
texture (6.6-6.7) and overall liking (6.4-6.7). The control, which
was flavored only with 1% salt, received the lowest rating for flavor
(4.2=dislike slightly). The most frequent comments made about the
control, garlic and cheddar cheese-flavored crackers were that they
were bland and soft. Cajun-flavored crackers were described as soft,
too salty, and having a lard taste. Some panelists described the
cheddar cheese/cayenne pepper crackers as being too hot or too salty
whereas an equal number considered them to be bland. These findings
indicate that further research to improve the texture and flavor
of these prototypes is needed. TABLE-US-00006 TABLE 6 Mean ratings

[0021] Table 7 shows the cracker purchasing, consumption, handling
and willingness-to-buy characteristics of consumers who participated
in the sensory evaluation of the illustrative peanut flour crackers.
Sixty percent of the panelists purchased crackers once a week, with
