Description

CROSS-REFERENCE TO RELATED APPLICATION

This application claims priority to U.S. Prov. App. No. 62/697,838 filed on Jul. 13, 2018, the entire contents of which are explicitly incorporated herein by reference.

TECHNICAL FIELD

The invention relates to the field of bread crumb coatings and pre-dust production, in particular, to pulse-based bread crumb coating and pre-dust production.

BACKGROUND

In general bread crumb, coating, and pre-dust products are produced by granulating or pulverizing cracker or bread made of wheat flour by baking process. Traditionally bread or sheeted crackers are used as base ingredient and milled to produce granulated crumbs and powders in formulated systems. Wheat flour, salt, sugar, bicarbonate salts, and vegetable oils are added in formulation to improve the sheeting and baking processes and in addition to enhance taste and sensory properties.
Wheat flour and other grain-based flours are mixed with water and variable ingredients such as salt, sugar, yeast, bicarbonate salts, and vegetable oils. After the mixing process, the dough is hydrated with a water absorption range of 55-63%. The hydrated dough is sheeted as thin sheeted cracker dough and baked further at a range of 200-240° C. The moisture is reduced down to 12-14% and then baked cracker particles are milled into variable granulations from coarse (i.e. >500 micron), granular (i.e. 500-150 micron), and fine (i.e. <150 micron) particle size.
Other methods such as extrusion can be also used to produce bread crumbs, coating, and pre-dust products. Wheat flour, corn flour, and other flours can be extruded into hard crust pellet, and are then milled into granulated crumb and powder products.
The wheat flour and other grain based flours are hydrated with water and variable ingredients such as salt, sugar, yeast, bicarbonate salts, and vegetable oils. In an extruder, the dough particles are hydrated with a water absorption range of 20-45%. The hydrated dough is extruded within a die at a temperature range from 120° C. to 160° C. During extrusion process, the moisture is reduced down less than 12% and then extruded dried dough particles were milled into variable granulations from coarse (i.e. >500 micron), granular (i.e. 500-150 micron), and fine (i.e. <150 micron) particle size.
A process for the production of legume meal is described in W.O. Pub. No. 2016/120234 to Ambiente E Nutrizione S.R.L. The process comprises the steps of: a) providing a wet heat treatment reactor comprising a cylindrical tubular body with horizontal axis, having an opening for the introduction of legume meal and water or an aqueous solution and having at least one discharge opening, a heating jacket and a rotor arranged inside the cylindrical tubular body; b) feeding a continuous flow of meal into the reactor, in which the rotor is rotated at a speed greater than or equal to 150 rpm; c) feeding into the reactor, together with the flow of meal, a continuous flow of water or aqueous solution, which is dispersed into minute droplets; d) centrifuging the aforementioned flows against the inner wall of the reactor, thus forming a highly turbulent, dynamic, thin tubular fluid layer, while advancing in substantial contact with the inner wall of the reactor towards the discharge opening; e) discharging from the discharge opening a continuous flow of a wet meal (moisture content 20-40%); f) providing a thermal dehydration and treatment reactor, comprising a cylindrical tubular body with horizontal axis, having at least one inlet opening and at least one discharge opening, a heating jacket and a rotor arranged inside the cylindrical tubular body and comprising a shaft provided with elements projecting radially therefrom; g) feeding the wet meal into the thermal dehydration and treatment reactor, the inner wall of the reactor being kept at a temperature of at least 100° C. and the rotor being rotated at a speed of at least 150 rpm; h) centrifuging and causing the wet meal to advance inside the reactor by the action of the rotor; i) discharging from the discharge opening of the reactor a continuous flow of legume meal having a moisture content of between 2% and 15%.

DETAILED DESCRIPTION OF THE DRAWINGS

There has been a recent increase in gluten-related disorders, such as celiac disease, non-celiac gluten sensitivity, wheat allergy, gluten ataxia, and dermatitis herpetiformis. This has been particularly problematic as some meats, etc. may be coated or bound with gluten-based products further limiting food selection for people with gluten-related disorders. As knowledge of these gluten-related disorders has increased, there has been a corresponding increase in the interest for gluten-free products. Example products may comprise gluten-free bread crumbs, powders, grains, and/or flakes.
Most conventional bread crumb coating contains some amount of gluten, especially if it is made from durum wheat flour. Pulse-based bread crumbs may be suitable for gluten-free and allergen-free applications that may be consumed by celiac patients, non-celiac gluten allergy, and gluten sensitive consumers. Pulse-based bread crumbs may be produced from pulses, such as, for example, peas, lentils, and faba beans. However, pulse flour and the pulse-based bread crumbs made therefrom may have an unappealing aftertaste for some consumers. By using processed pulse flours and specifically pulse flours processed using heat and moisture treatment as described herein, the process may produce improved taste, flavor, appearance, and sensory properties in comparison with the conventional bread crumb, powder, grain, and/or flakes.
Low protein and medium protein pulse flours may produce a bread crumb, coating, and/or pre-dust analog by using a combination of steam, water, and/or heat in a reactor as a single allergen-free pulse-based ingredient as described further with reference to FIG. 1 . Pulse flours may be produced by cleaning 100, dehulling, 102, fine milling/grinding 104, classification 106, heat and moisture treatment 108, and drying and milling processes 110 in which the flow, taste, and/or sensory properties of the flour may be enhanced as described herein. For example, bread crumbs, powders, grains, and/or flakes made according to the process of FIG. 1 may exhibit a reduced pulse flavor. Although the aspects described herein are directed to peas, one or more of these techniques may equally apply to other pulses, such as, but not limited to, lentils, faba beans, navy beans, pinto beans, and/or black beans (or any combination thereof).
The cleaning process 100 may be applied to remove impurities from whole peas so that product cleanliness may be sustained. During the cleaning process 100, impurities such as chaff, other crops, stones, black-off colour kernels, damaged and/or broken seeds may be removed.
Dehulling 102 may be applied to produce dehulled pulses (e.g. split peas, split lentils, or split faba beans) and to remove outer hulls so that outer fiber portion of the peas may be removed to remove the fiber and to increase the yield of protein and starch separation. The outer hulls may be removed in the dehulling process 102 using mechanical forces applied by peelers. Since the hulls adhere on a cotyledon on the outer part of a kernel, these forces may help remove the outer hulls from the whole kernel and separate cotyledon.
Fine milling 104 process may be applied to the split peas to produce a raw pulse flour with a particle size of below about 80 microns. The particle size of below about 80 microns may assist in classification 106 in order to separate a starch fraction from a protein fraction. This particle size may apply particularly to peas, lentils, faba beans, and/or other low fat pulse crops. The fine milling 104 process may use various systems such as, for example, a pin mill, an ACM mill, a turbo jet mill, and/or other fine grinding systems. The lower particle size of the raw pulse flour may assist separation of the protein and starch granule. At this fine particle size, the protein bodies may be removed from starch granules using such techniques as described in at least U.S. Pat. No. 1,861,248 to Stebbins or U.S. Pat. No. 3,089,595 to Alpine Ag Maschinenfabrik Und.
During classification 106, the raw pulse flour may be separated into a limited protein pulse fraction with a protein range of less than about 16% dry weight. The medium protein pulse fraction having over between about 20% to about 36% dry weight protein may also be used within blending systems in processing. The classification 106 may be performed by a classifier such as produced by Hosokawa Alpine Aktiengesellschaft, Sturtevant, etc.
Rather than classification 106, the limited protein pulse fraction may comprise medium (20-32%) level pulse flours (after fine milling 104) and may be blended with pea, lentil, and/or faba bean starch isolates (e.g. starch content >97% and protein <3%). Pulse starch isolate may be used as texturizing agents combined with medium protein pulse flours to establish protein levels at a range of 7-16%.
Heat and moisture treatment 108 may be applied to improve sensory and flavor attributes of the limited protein pulse flour fraction. The limited protein pulse flour fraction may also be agglomerated as part of the heat and moisture treatment 108. In some aspects, the agglomeration may be performed with a press mixer kneader operating in a range of about 80-rpm to about 130-rpm. The initial moisture content of the limited protein pulse flour fraction before hydration may be between about 4% to about 12% and may be measured prior to hydration in order to determine the amount of hydration required.
In some aspects, the limited protein pulse fraction may be hydrated at a range from about 18% to about 55% by weight with water in a temperature range of about 30° C. to 90° C. at atmospheric pressure to produce a hydrated pulse dough crumbles with a temperature range of about 70° C. to about 85° C. The high temperature water and/or high pressure steam may be added and mixed to produce agglomerated pulse dough. The agglomerated dough may be heated to a temperature of between about 95° C. to about 150° C. to cook and dry the agglomerated pulse dough to a moisture content of less than about 12% moisture.
The hydration, heat, moisture treatment, and drying of the limited protein pulse flour fraction reduces levels of volatiles (e.g. hydrocarbons, alcohols, ketones, and/or aldehydes) as well as inactivates bitterness compounds (e.g. saponins, lectins and phenolics) improving the taste, flavour, and/or aroma. In particular, a sensory evaluation comparison presented in FIG. 2 demonstrates the altered taste, flavor, and/or aroma characteristics between the pulse flour and the heat and moisture treated pulse flour. In particular, a pulse taste has been reduced from a strong taste (e.g. 8) to a more mild pulse taste (e.g. 3). The bitterness has also been reduced by half (e.g. from 6 to 3). During the heat and moisture treatment, a roasted flavor may be introduced (e.g. from 0 to 3) into the pulse flour, which may be preferable to the pulse taste for a consumer.
The agglomerated pulse dough pieces may be sifted and/or milled 110 into coarse (e.g. over 2362 micron), granular (e.g. between 800 micron to 2362 micron), and fine (e.g. less than 297 micron) as typical fractions. The agglomerated pulse dough may be milled 110 using a fine grinding system such as, for example, an ACM mill, pin mill, turbo jet mill, roller mill or any fine grinding system, and passed through a standard US 100 mesh.
When the bread crumb, coating, pre-dust analog products described herein are used; allergen free, gluten free and single ingredient claims may be imparted. The bread crumbs, coating, and/or pre-dust analog may be applied to fried foods (e.g. breaded chicken, chicken nuggets, shrimp, fish, and/or fries). The resulting fried product may not be too hard based on internal sensory evaluation in oral sensation of coating and may maintain a crispy sensation for about 2-hours in fresh applications and 6-months in frozen applications. The bread crumb may also be mixed into sausage, meatballs, snack foods and/or bakery products and may also be mixed with cereal materials such as trail mixes, soups, and/or granola bars in dairy food systems.
According to an aspect, the pulse-based bread crumb, coating, or pre-dust may be applied as a coating to a breaded food product at an inclusion rate from about 1% to about 10% by weight. The food product may comprise a fried chicken nugget, a fried shrimp, a fried fish, a potato product (e.g. French fries), a meat analogue, a texturized analogue, a canned analogue, vegetables, fruits, pickles, and a generic fried food product.
According to another aspect, the pulse-based bread crumb, coating, or pre-dust may be used as a binder in sausage, meatball, snack food, and bakery products at an inclusion rate from 1% to 20%.
One or more nutritional properties of finished bread crumb produced from peas is given in Table 1.
