Over the years the food industry has explored and made new advances in non-animal proteins as a possible alternative for traditional meat. A famous technique for achieving this is high pressure processing, a technique we talked about in class! @UofGFoodProf #Jones
van der Waals forces have 3 classes:
1. Keesom force - interactions between 2 permanent dipoles
2. Debye force - interactions between a permanent dipole and an induced dipole
3. London force (common in fats) - interactions between two induced dipoles

High pressure processing, which is the process of placing a product in a relatively cold water tank at approximately 58,000 psi to inactivate vegetable flora, is useful in stabilizing things like fresh juices. This is important as it increases shelf life @UofGFoodProf #Nienaber
@UofGFoodProf One of the ways that producers increase shelf-life of orange juice is by using high-pressure processing. The best results determined in the #Nienaber study was that 500 MPa was satisfactory in inactivating PME for preservation. @UofGFoodProf #Food2150
Super-critical fluid is an uncommonly discussed state of matter that occurs when temperature and pressure are beyond critical point, so liquid and gas phases do not exist. SCF plays a role in industrially applied technology such as multi-stage extraction. #Brunner @UofGFoodProf
According to Warriner et al., the presence of a symbiotic population of bacteria, known as endophytes, in salad fruits and vegetables limit efficiency of post-harvest biocidal washing. Huge problem considering that pesticides are a huge part of harvest. #Warriner @UofGFoodProf
A study conducted by Lebert et al. demonstrated that bacteria such as E. coli and Salmonella are more frequently found in commercial broiler flocks than smallholder chicken flocks despite having a similar rate recovery rate of E. coli in caecal samples. Hmm..@UofGFoodProf #Lebert
Acid whey troubles the dairy industry. It's produced as a by-product when yogurt is concentrated with protein after fermentation. Craving "gainz"? Buy yogurt that's concentrated prior to fermentation... Not really worth the extra charge in my smoothie. @UofGFoodProf #Jørgensen
Visceral fats, surrounding organs and located in the abdomen region, produce more amounts of the proteins responsible for energy production and are smaller than subcutaneous fats, sitting under the surface of our skin.

@UofGFoodProf #assignment#food2150#cordain An estimated 280,184 people die per year due to obesity. A factor being our historic genome has not evolved to meet our new diets, 72.1 % of the total daily energy intake (US) is from products unavailable to preagricultural diets.
Interestingly, there is huge variation of biting force exerted by the different types of teeth in the oral cavity, with further difference between ethnic groups and genders within. Compelling topic for future study I would say! @UofGFoodProf #Chen#assignment
Soft music encourages a slower rate of eating, longer meal duration, and a higher consumption of food and drinks. When preferred music is heard, individuals stay longer and order more food or drinks since they feel more comfortable. @UofGFoodProf #Food2150#assignment#Wansink
Research shows that the majority of US citizens lack soluble fibre consumption in their diet. Soluble fibres aid in CVD prevention by regulating LDL cholesterol. Seeing CVD magnify every year makes me understand why my parents made me eat all my veggies @UofGFoodProf #Cordain
