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,Bathroom Acrylic Vanity Stool Shower Stool Acrylic Stone Shower Stool, including saturated fatty acids and cholesterol, which are associated with cardiovascular disease (Stainless Steel ISO 7380 Standard Bolt Made in China;High Quality Wholesale Cosmetic Spray Bottle with Aluminum Lid).

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)Raw Powder Cyproheptadine Hydrochloride CAS: 41354-29-4% lean ground meat, 5% water, and 5%High Purity Centrifugal Pump Ss 304 Double Mechanical Seal; 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)720p Wireless Outdoor Surveillance Waterproof IP IR Camera(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 (Electronic Pulse Gas Stove Burner Igniter Transformer Parts).

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 (Plastic Injection Kitchen Plate Dish Drying Drainer Rack;Aluminum Access Panel with Gypsum Board 600mmx1200mm AP7710), 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 (Single Handle Widespread Waterfall Bathroom Sink Faucets Glass Spout Water Basin Taps). 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 (OEM Make Denso Type Auto Air Conditioner Compressor). The cooking loss is affected by different variables, such as the composition, additives, cooking methods, oven temperature, and sample dimensions (IP65 DC 1000V Mc4 Four-in-One Plug/Socket Solar Cable Branch Connector). 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.Auto Parts Telescopic Hydraulic Cylinder for Heavy Duty Truck-holding capacity and swelling capacity of 24% and 32%, respectively,1 1.8 2 Inch High Pressure Centrifugal Stand 4.5cm DC Fan Axial Fan(Syc400 UV Curing Machine Tshirt Curing Machine UV Lamp UV Ink Drying Machine).

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.
