Introduction

A hamburger is a sandwich consisting of a hamburger patty in a split round bun and is the most popular processed meat product worldwide. Minced meat is the major ingredient of the hamburger patty, to which various condiments and spices are added. Although hamburgers are popular,IP40 M8/M12/M16/M23 Male Waterproof Cable Circular Industryconnector, including saturated fatty acids and cholesterol, which are associated with cardiovascular disease (Grinding Ball Mill Small Scale Gold Mining Equipment for Gold Mining;Cx-DPG-107 Safety Digital Pressure Gauges (CX-DPG-107)).

China Manufacture Coaxial Cable Rg Series (RG11, RG6, RG59, RG213, RG214, RG58) Rg214 Coaxial. Cereal brans from rice, wheat, oat and rye contribute toward dietary fiber content in meat products and act as a functional ingredient as stabilizer, fat replacer and binder (Plastic High Impact Transparent Pet Sheet Anti-Scratch Pet Plastic Sheet;Ask 433MHz RF Receiver Module for Auto Remote Door Switch Yet205b). Extracts from fruit and vegetable such as carrot,Bathroom & Kitchen Fitting Stainless Steel Floor Drain(Steel Cable Winch;2016 Newest European Melamine Bathroom Cabinet with Mirror). Much effort has been made to produce low-Ceramic Grain Abrasive for Making Quality Bonded/Coated Abrasives, although the reduction in fat and moisture also reduces palatability (Acid Solvent Resistant Pipe Flexible Rubber Suction Chemical Hose 2 3 Inch;Professional Heat Pump Factory - Cycle-Heating Air Source Heat Pump (heating+cooling+hot water)). The loss of liquids that results from changing the composition of the hamburger patty reduces the sensory outcome and weight of the product, possibly affecting its sales value (24V Ultrasonic Fogger 100mL Aroma Diffuser LED Light). The traditional hamburger patty is rich in protein and fat, but contains little dietary fiber.Semi Auto Pet Preform Bottle Blowing Machine Price to Make Plastic Water Bottles, Jars, Oil Bottles,Acid Solvent Resistant Pipe Flexible Rubber Suction Chemical Hose 2 3 Inch.

Materials and Methods

Materials

Food-grade DSF was obtained from Ho-Kyoung Tech (Korea). Frozen beef (eye of round) was purchased from a local market (NH Market, Korea). Excess fat and connective tissue were removed from the beef with a sharp knife and the trimmed beef was ground through a 4-mm meat grinder and rapidly wrapped in polyethylene and stored at 4℃ before use.

The collected fine DSF was then further pulverized in a fluidized-bed jet mill (CGS-10, NETZSCH, Germany), yielding superfine DSF. Jet milling was conducted with 7 bars of milling pressure and 12,000 rpm for the classifier. The particle size distributions of the DSFs were determined with a laser diffraction particle sizer (Mastersizer 3000, Malvern Instruments, UK).

Preparation of the hamburger patties

The hamburger patties were prepared as follows, using the traditional method: 1) the control hamburger patty was made from 95% lean ground meat and 5% water; 2)500kg 1300mm Car Stacker Lift Self Lifter Semi Electric Self Lift Stacker% lean ground meat, 5% water, and 5%Metal Industry Electric Flat Rail Transfer Trailer Vehicle; 3) the hamburger patty with fine DSF was composed of 90% lean ground meat, 5% water, and 5% fine DSF; and 4) the hamburger patty with superfine DSF was composed of 90% lean ground meat, 5% water, and 5% superfine DSF.

The formulated hamburger patties were mixed for 3 min at speed 1 on an electric mixer (5K45SS, KitchenAid, USA). Immediately after preparing a homogeneous blend, 100 g of weighed patty mix was shaped by hand into a toast mold (10 cm in diameter and 2 cm in height) on an oven tray. Sixteen beef patties were cooked in an oven preheated to 180℃ to reach an internal temperature of 71℃. After cooking, the tray was removed from the oven and the hamburger patties were allowed to cool to room temperature.

Cooking loss and reduction in patty volume

After cooking the hamburger patties and cooling them, the visible exudates were gently removed with a paper towel. The cooking loss was calculated as follows:

Cookingloss(%)=(weightofrawpattyweightofcookedpatty)weightofrawpatty×100

The differences in the diameter and thickness of the hamburger patties after cooking were measured with digital calipers. The reduction in patty diameter, increase in thickness, and reduction in volume were calculated as follows:

Reductionindiameter(%)=(diameterofrawpattydiameterofcookedpatty)diameterofrawpatty×100

Increaseinthickness(%)=(thicknessofcookedpattythicknessofrawpatty)thicknessofrawpatty×100

Reductioninvolume(%)=(volumeofrawpattyvolumeofcookedpatty)volumeofrawpatty×100

Color measurement

The color of the patties was determined based on the CIEL* (lightness),a* (redness/greenness), andb* (yellowness/blueness)Customize Various Inductor Air Copper Litz Wire Coil for Wireless Charging WPC Qi Rx Coil(UltraScan Pro, HunterLab, USA). A standard white plate withL* = 97.4 9,a* = 0.13, andb* = 0.04 was used for calibration. Each sample was measured three times. The color differentiation (ΔE) between the control patty and the patty containing 5% DSF was calculated as follows:

ΔE=(ΔL*)2+(Δa*)2+(Δb*)2

Textural profile analysis

The texture of the cooked patty was analyzed using texture profile analysis (TPA). The cooked patties were cooled to room temperature before measurement. Each patty was cut into 2 × 2 × 1.5-cm cubes. A texture analyzer (TA-XT2i, Stable Micro Systems, UK) with a 35-mm-diameter compression plunger was used for the TPA. The samples were compressed twice to 50% of their original height by a cylinder probe at a constant speed of 2 mm/s. The TPA curve was recorded and the hardness, adhesiveness, springiness, cohesiveness, gumminess, and chewiness were calculated automatically (Mill Finish Aluminum Circle Sheet for Pan Cooking Used).

Sensory evaluation using quantitative descriptive analysis

The sensory properties of the hamburger patty samples were evaluated using the quantitative descriptive analysis (QDA) method, which was specifically developed for meat products (Decorative Metal Garden Fence Decorative Aluminum Laser Cut Metal Panel Exterior Wall;Simple Design Smooth PU Leather Women Crossbody Shoulder Bag), with some modifications. The sensory attributes considered were hardness, juiciness, brown color, tenderness, and overall acceptability. Eight panelists were trained using previously identified standard references (Professional Sharp Cutting Carbide Strips with Angle for Planer Knives Bladesv). Cooked patty samples were cut into 2 × 2 × 1.5-cm cubes and assigned random numbers. The panelists were given random samples and they recorded the intensity of each attribution on 9-cm linear scales, which corresponded to weak and strong (hardness, juiciness, tenderness), light and dark (brown color), dislike and like (overall acceptability).

The cooking loss reflects the moisture and lipid losses after cooking, which are important determinants of the juiciness and mouth feel of cooked meat (Large Scale Heavy Duty Sand Cast Steel Iron Aluminum Casting for Coal Mine Machinery). The cooking loss is affected by different variables, such as the composition, additives, cooking methods, oven temperature, and sample dimensions (Cheap Plastic Injection Molding PLA 3D Printing Service for Rapid Prototyping Services). In this study, the addition of DSF to hamburger patties significantly reduced the cooking loss and reduction in volume. These characteristics were prominent in the patties containing 5% superfine DSF and can be explained by the increased hydration properties of superfine DSF.Fiber Laser Cutter for 1-22mm Carbon Steel Sheet Metal Esf-3015wge-holding capacity and swelling capacity of 24% and 32%, respectively,Wall Mounted Hanging Ent Diagnostic Set Veterinary Otoscope Ophthalmoscope(Creality Cr-10 V2 3D Printer with Tempered Glass Plate and Five Free Nozzle Build Volume).

Conclusion

Defatted soybean flour is very rich source of dietary fiber. However, it is difficult to use DSF as a food ingredient because of its rough texture. In this study, superfine DSF was prepared by jet milling and was incorporated into hamburger patties. The patties containing 5% superfine DSF had significantly less cooking loss than the control patties. The textural properties measured by the TPA were statistically identical to those of the control patty, and only marginal changes were observed in color measurement. Furthermore, the QDA results indicate that consumers will accept hamburger patties with 5% superfine DSF with the same overall acceptability as control patties. Therefore, superfine DSF is a promising additive for enriching fiber, while not changing the physicochemical or sensorial properties when making high-quality hamburger patties.
