The idea is to create a film for food packaging that will change color to indicate if the food inside is spoiled. The film will change from yellow to blue in the presence of biogneic amines- the molecules that are produced when food spoils.

Vending business occupies a leading position in the list of the most profitable and popular types of the third millennium business. Through vending machines you can buy almost any product, ranging from household appliances to fresh products, such as pizza, carrot and even meat. Manufacturers of vending machines are constantly improving machines and accommodating them to the customer needs. A good example of improved vending machine can be the one which appeared on one of the...

The creation of antibacterial paper has been attempted before, but this method seems to be the most effective. Why not create food packaging impregnated with silver nanoparticles? This will kill bacteria and help prevent food from spoiling.

The idea is to create little stickers that will be stuck to each grocery store item and will then dissolve into an organic soap. The sticker will dissolve with water into a natural soap that will help to wash away pesticides, wax, bacteria, and dirt. The labels will still display the same PLU codes and other information as their less soapy contemporaries.

My idea is to use the same clay ingredient as in bricks to create a packaging that can help foods stay fresh longer. The new film will be made up of 70% montmorillonite clay, with a structure similar to conventional bricks and mortar. Conventional packaging could be sprayed with or dipped in the film, creating a layer less than 100 nanometers thick. This extremely fine layer will be 100 times more resistant to penetration by oxygen than the current silicon oxide films.

Wine bottles made from a paper based glass will cost less to produce than conventional glass and will have only 10 percent the carbon footprint. The paper wine bottles will weigh only 50 grams, instead of the 500 grams of a standard wine bottle. Its shape and dimensions will be the same, however, so it can be easily integrated into existing displays. The wine itself will be contained within a foil bladder similar to a wine box. The paper wine bottles could be useful for...

Most people think that cooking a perfect hard-boiled egg is a chance-by-chance situation. Sometimes you do it right, sometimes you don't. To succeed you just need the perfect technique, which is detailed below: 1. Wait for the eggs to be old enough for peeling. Young eggs are the most difficult to peel. To make sure that you'll be boiling old-enough eggs, keep them in the refrigerator first for about a week before boiling them. 2. Take the eggs out of the refrigerator....

My problem is that I'm too lazy to cook for myself... eating in restaurants is expensive and fast food is not tasty and good for health. If you have similar problem then you'll like my idea. I suggest creating a web site where amateur cooks will sell dishes of their preparation. There will be an opportunity to find diet food, different national dishes, etc. The prices will be specified by sellers but they will always be able to feed other people even for free. Buyers will use...

An old home remedy for sore throats is a tea made with lemon, apple cider vinegar, cayenne and honey. Add one teaspoon of apple cider vinegar, a tiny pinch of cayenne pepper, the juice of 1/4 lemon, and one teaspoon of honey to a cup of hot water. Stir. It is suggested to drink up to four cups of such tea a day.

I wish there was a chef jacket with nano-fabric. It would be water resistant, stain resistant, anti-microbial and moisturize release & breathable. Nanotechnology is a technology based on the manipulation of individual atoms and molecules to build structures to complex, atomic specifications. These proprietary technologies would alter fabrics at the molecular level, creating advanced performance and durability through the life of the fabric.
