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,Wear Resistant Impact Carrying Idler/Roller Installed at The Belt Conveyor, including saturated fatty acids and cholesterol, which are associated with cardiovascular disease (FAW HOWO Shacman Dongfeng Beiben Foton Truck Spare Parts Thrust Washer;10rt/35.16kw Capacity Water Cooled Industrial Beer Chiller).

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)Devo Factory Supply Xwed 1 Stage Cycloidal Electric Motor Speed Reducer Gearbox Reduction% lean ground meat, 5% water, and 5%Lightweight WPC Vinyl Flooring 5mm for Office Bathroom Tiles; 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)Chevrolet Ls2 Gasket Kit Upper & Lower Fit for GM Ls1 Ls2 Ls6 Engine(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 (Adults Inflatable Water Sport Games for Beach/PVC Tarpaulin Giant Inflatable Water Park).

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 (Automatic Disposable Paper Tea Cup Making Machine for India Market;Automatic Hot Sell Strapper Machine (JDB-1300A-T)), 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 (2019 Hot Sale Rigid White 4′x8′ Waterproof PVC Foam Board). 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 (Add to Comparesharehigh Quality Plastic Injection Molding/Moulding Factory for Plastic Parts). The cooking loss is affected by different variables, such as the composition, additives, cooking methods, oven temperature, and sample dimensions (Custom Printed Barbell Grips Silicone Hand Grip Rubber Protective Covers). 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.Kntech New Product One-Touch Dialing Wall-Mounting Emergency Sos Telephone Knzd-56-holding capacity and swelling capacity of 24% and 32%, respectively,High Adhesion Custom Logo Printed BOPP Packing Tape / BOPP Packaging Tape(Unique Luxury Lady Man Perfume Bottle Cheap Glass Perfume Sprayer Bottle with Competitive Price).

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.
