FOOD

What are these?

These products are made (engineered) using a machine called Food Extruder

And these?

Control Panel

Hopper(flour, water, sugar, Salt, flavors, color)

Barrel (heated or cooled)

Have you heard of Rutgers Tomato?

Great flavor, pest resistant, and mechanically harvestable

SO, WHAT’S IN A TOMATO?

Lycopene

• Red pigment from the carotenoid family.• Naturally found in fruits and vegetables.• Health-promoting antioxidant properties.

(reduces risk of prostate, bladder, skin, lung, breast, cervical cancers)

• Better absorbed from processed tomatoes

WHAT’S IN A GRAPE?

RESVERATROL

Anti-oxidant, good for

WHAT’S IN A KIWI?

Lutein

Good for

Egg yolk, corn, zucchini, red grapes, pumpkin are also rich in lutein

Anti-inflammatory activities of flavonoid fractions isolated from

cranberry

WHY ARE GUMMY BEARSGUMMY?

Because they contain Collagen

The Future

What Do We Expect From Foods As We Move Into the Future?

Safe, convenient, and high qualityIncrease healthfulness and prevent disease, boost performance Be appetizing and funCulturally more diverse Designer foods Minimum disposable waste - biodegradable

New texture flavor conceptsMinimally processed ready-to-eatMaximize freshnessInexpensiveSpace foodsPackaged functionally and attractively

Science and Technologies Which Will Play an Increasing Role in Food Science and

EngineeringMolecular biology and biotechnology

Food gene interactions

How can we get health-promoting compounds of tomato, asparagus, kiwi fruit, grapes, fenugreek, thyme, bay leaves, almond skins,…… delivered through food products?

Fish oil (containing Omega-3 fatty acids) is good for your health but it smells (stinks!!): How can we mask the undesirable odorand incorporate fish oil into food products?

Pulsed Light Processing

• Intense, short duration, broad-spectrum light is exposed to a food or package

• Very effective on product surfaces• Marginally effective at penetrating to depths in foods• Reduces the need for chemical disinfectants and

preservatives

People like to eat raw oysters and clams (because of their tasteand flavor), but are concerned because they could contain harmful bacteria.

How can we overcome this without steaming/grilling the oysters?
