Meat substitutes - Plant Proteins
Soybeans/Soy proteins
• Tofu - gel is from soy PRO
• CaSO4, CaCl2 ← helps form the gel → What helps the soy PRO form the gel is the
utilization of Ca salt compounds in the product
o Adds a certain amount of Ca so that it can act to some degree as a soy protein
o Milk soy → cannot be marketed as a milk, Soy beverage (because of its plant
PRO like quality
• E.g: Tempeh (preparation of )
• Extra firm tofu and soft dessert tofu
o The moisture will determine the texture
o Allowing the moisture to slowly leave the tofu to get a firmer product
o How do you produce soy milk? Heating soy beans with water, removing hull and
mashing the beans
o Remove some of the less soluble PRO based components (fibrous components)
yuba:
• How they form? film forming on top of heated milk
• Thin sheets of soybeans
• Film protein that form on top of the soy milk beverage
• You can lift off the film and dehydrate it and use those as soy protein sheets
• E.g: seen in dim sum, buddhist restaurant
Textured plant/ veg protein
• Processing or heating the product to change the overall texture (origin of:
texturized PRO)
• Adding a lot of flavours and extra ingredients to make it more like a (meat
product) and making the label more complex than we’d want to
• E.g: veggie dogs
• Those veggie dogs are pretty similar to that block of tofu. They’re just more seasoning.
Microwaves chapter (why yvonne this is so random T_T)
Microwaves Energy
• Continuous unit of the electromagnetic spectrum
• Very close to the radio wave frequency
• Visible light is further away
• UV has just a little bit of overlap
• Very high energy X rays and gamma rays
Microwaves and radio waves are less damaging than X rays and gamma rays so it’s safe to
heat up food
Wavelength → talk about it in terms of visible light, nm
Microwaves wavelengths are in centimeters = Greater than visible light
• Gives us idea of the magnitude of the different size of the Wavelengths
*DO NOT NEED TO MEMORIZE: know general types of differences and relationships b/n*

Document Summary
Microwaves chapter (why yvonne this is so random t_t) Microwaves energy: continuous unit of the electromagnetic spectrum, very close to the radio wave frequency, visible light is further away, uv has just a little bit of overlap, very high energy x rays and gamma rays. Microwaves and radio waves are less damaging than x rays and gamma rays so it"s safe to heat up food. Wavelength talk about it in terms of visible light, nm. Microwaves wavelengths are in centimeters = greater than visible light: gives us idea of the magnitude of the different size of the wavelengths. *do not need to memorize: know general types of differences and relationships b/n* Very strongly absorbed x ray, want to be protected (that why they put that heavy apron thing on you when you get an x-ray) Radio waves aren"t quite as well absorbed and can be reflected as well as transmitted.
