The sentence that led me to this answer is: "3D food printing is poised to revolutionize the gastronomic landscape by offering precise and customized food creations." Essentially, 3D food printing allows for a level of control and customization over food that was previously impossible. It opens up a world of possibilities for chefs, nutritionists, and individuals looking to create unique and tailored culinary experiences.

By using critical things way and study from the scientific paper name Printing the future of food: The physics perspective on 3D food printing by Muhammad Waseem, Asad Ullah Tahir and Yaqoob Majeed. Precise: 3D food printers can create food with exact measurements and shapes. This level of control is difficult to achieve through traditional cooking methods. Customized: You can design and create food that meets specific dietary needs, allergies, or personal preferences. This level of personalization is unmatched by traditional cooking. So essentially, 3D food printing allows for a level of control and customization over food that was previously impossible. It opens up a world of possibilities for chefs, nutritionists, and individuals looking to create unique and tailored culinary experiences.

If a 3D printer deposits a food layer with a thickness of 0.1 mm and builds up to a height of 20 mm, how many layers are required?

If each layer is 0.1 mm thick and we want to reach a height of 20 mm, we divide the total height by the thickness of one layer: 20 mm / 0.1 mm/layer = 200 layers.

A printer uses an extrusion process where the food material flows at a rate of 5 mm³/s. How long will it take to print a food item of 1000 mm³

So, I think the answer is 200 seconds. To figure this out, we need to divide the total volume of the food item by the rate at which the material flows. The total volume of the food item is 1000 mm³. The material flow rate is 5 mm³/s. So, the calculation is: 1000 mm³ / 5 mm³/s = 200 seconds.

If a 3D printer uses a laser with a power of 10 W and the efficiency of converting electrical energy to thermal energy is 80%, what is the actual thermal energy used for printing?

So, I think the answer is 8 W. We're told that the laser has a power of 10 W, but the efficiency of converting electrical energy to thermal energy is only 80%. To find the actual thermal energy used, we need to calculate 80% of 10 W. 80% of 10 W is equal to (80/100) * 10 W = 8 W. Therefore, the actual thermal energy used for printing is 8 W.

Which functional property of gluten is NOT improved by EFAF according to the article?

So, I think the functional property of gluten that is NOT improved by EFAF is Gluten Elasticity. While the article extensively discusses how EFAF enhances water holding capacity, emulsifying properties, and foaming properties, it doesn't specifically mention any improvements in gluten elasticity. The article focuses primarily on the effects of EFAF on these three functional properties, and there's no direct evidence suggesting that elasticity is positively impacted.

If the WHC (Water Holding Capacity) of gluten increased by 0.25% under 900 V electrostatic field compared to the control, what would be the new WHC if the original was 55%?

If the original WHC was 55% and it increased by 0.25% under a 900V electrostatic field, we need to add 0.25% of 55 to the original value. 0.25% of 55 is (0.25/100) * 55 = 0.1375 Now, add this increase to the original WHC: New WHC = 55 + 0.1375 = 55.1375 Therefore, the closest answer is 55.15%.

If a sample of gluten (50 mg) is added to 4 mL of water and centrifuged, resulting in a dry weight of 20 mg, what is the WHC?

First, we need to determine the amount of water held by the gluten. We start with 50 mg of gluten and end up with 20 mg of dry weight, so the gluten held 50 mg - 20 mg = 30 mg of water. The formula for WHC is: WHC = (Amount of water held by gluten / Dry weight of gluten) * 100 Plugging in the values: WHC = (30 mg / 20 mg) * 100 = 1.5 So, the WHC is 1.5.

Assuming the electrostatic field changes the orientation of water molecules, what physical property does this directly influence during freezing?

The key piece of information is that the electrostatic field changes the orientation of water molecules. This change in orientation affects the overall energy state of the system, which is directly related to free energy. Free energy is a thermodynamic property that measures the potential for reversible work. By altering the water molecule orientation, the electrostatic field changes the system's energy state, thus impacting its free energy.
