What nanoparticles are used in food?

Types of nanoparticles in foods

• Silver nanoparticles. Silver (Ag) nanoparticles are used in a variety of applications within the food industry.
• Zinc oxide.
• Iron oxide nanoparticles.
• Titanium dioxide (TiO2) nanoparticles.
• Silicon dioxide nanoparticles.
• General comments.
• Lipid nanoparticles.
• Protein nanoparticles.

What are the characteristics of nanoparticles?

There are three major physical properties of nanoparticles, and all are interrelated: (1) they are highly mobile in the free state (e.g., in the absence of some other additional influence, a 10-nm-diameter nanosphere of silica has a sedimentation rate under gravity of 0.01 mm/day in water); (2) they have enormous …

How nanoparticles are helpful in food safety?

In food processing industries, nanoparticles are used to enhance food stability and maintain food color. Silicate nanoparticles can restrain the flow of oxygen in packaging containers and restrict moisture leakage. This ensures the food remains fresh for a longer duration.

How are nanoparticles used in the food industry?

Application of bioactive phytochemicals in foods, supplements, and pharmaceuticals is often limited because of their poor solubility, stability, and bioavailability. Phytochemical oral delivery systems (PODS), consisting of phytochemical-loaded nanoparticles or microparticles, can overcome these challenges.

What foods contain nanoparticles and what foods don’t?

As reported by Food Safety News, other packaged foods contain “engineered particles,” including salad dressings/sauces, diet beverages, and boxed cake, muffin and pancakes mixes — however these are somewhat different than nanoparticles.

Is it safe to use nanotechnology in food?

Many experts believe that nanotechnology in food is safe and nothing to be concerned about since the human body is already accustomed to using nanosized food particles, considering our own digestive systems break down bigger nutrients into small bits every day.

What kind of nanoparticles are used in pods?

PODS contain structurally designed food-grade nanoparticles or microparticles. PODS include nanoemulsions, solid lipid nanoparticles, liposomes, and microgels. Application of bioactive phytochemicals in foods, supplements, and pharmaceuticals is often limited because of their poor solubility, stability, and bioavailability.
