Summary
Active lipid nanoemulsions improve the solubility and stability of food ingredients. These nano-sized structures enhance biological functionality and offer benefits over conventional emulsions.
Area of Science:
- Food Science and Technology
- Nanotechnology
- Biochemistry
Background:
- Incorporating lipophilic active compounds (e.g., antimicrobials, health-promoting substances) into food is challenging due to poor water solubility and instability.
- Conventional emulsions often struggle to effectively deliver these sensitive compounds.
Purpose of the Study:
- To explore the potential benefits of active lipid nanoemulsions for improved delivery of lipophilic compounds in food.
- To review studies comparing nanoemulsions with conventional emulsions for food applications.
Main Methods:
- Review of scientific literature focusing on active lipid nanoemulsions.
- Analysis of studies investigating the impact of nanoemulsification on solubility, stability, and biological functionality.
- Comparison of nanoemulsion performance against conventional emulsion systems.
Main Results:
- Nanoemulsification significantly enhances the surface area per mass unit of active compounds, improving solubility and stability in food matrices.
- Reduced particle size in nanoemulsions facilitates enhanced penetration across biological membranes.
- Active lipid nanoemulsions demonstrate superior performance compared to conventional emulsions in delivering lipophilic ingredients.
Conclusions:
- Active lipid nanoemulsions represent a promising strategy for overcoming challenges in incorporating lipophilic compounds into food products.
- The enhanced solubility, stability, and bioavailability offered by nanoemulsions boost the overall functionality of food ingredients.

01:27Bioavailability Enhancement: Drug Permeability Enhancement
314
After oral administration, poor permeability often limits the rate at which drugs are absorbed through the intestinal epithelium. Enhancing drug permeability is crucial for effective therapy, and several strategies have been developed to overcome this challenge.One effective strategy involves the use of lipid-based formulations. These formulations enhance dissolution and solubility, targeting physiological mechanisms to increase drug absorption. This includes stimulating bile salt secretion,...

01:24Modified-Release Drug Delivery Systems: Site-Targeted
130
Site-targeted drug delivery systems enhance therapeutic efficacy while minimizing systemic toxicity and treatment costs. Unlike conventional methods, these systems ensure precise drug delivery, improving bioavailability and reducing side effects. Targeted drug delivery is classified into three levels. First-order targeting directs drugs to the capillary beds of specific organs or tissues. Second-order targets specific cell types, such as tumor cells, using receptor-mediated interactions.

125
Polymeric carriers enhance targeted drug delivery by increasing efficacy while minimizing off-target effects. These carriers comprise a biodegradable polymeric backbone integrated with functional elements that enable targeting, improve physicochemical properties, and regulate drug release.Targeting MechanismsThe targeting ability of polymeric carriers is mediated by a homing device, which is a molecular recognition component designed to selectively bind to specific tissues or cells. Monoclonal...

245
Ophthalmic drug delivery faces major limitations due to poor absorption across the corneal membrane. This process is primarily driven by diffusion and is influenced by two main factors: the physicochemical properties of the drug and tear drainage. Most ophthalmic drugs, such as pilocarpine, epinephrine, atropine, and local anesthetics, are weak bases. They are typically formulated at an acidic pH to enhance chemical stability. However, this leads to high ionization, reducing their ability to...

01:11Oral Drug Delivery Systems: Delayed-Release Systems
175
Delayed-release drug delivery systems are specialized pharmaceutical formulations designed to postpone the release of active compounds until the drug reaches a specific region of the gastrointestinal (GI) tract, typically the intestine. These systems are essential for drugs that may cause gastric irritation, are unstable in acidic environments, or need to exert therapeutic effects locally in the intestinal or colonic regions.The core feature of delayed-release systems is the use of enteric...

143
Parenteral drug delivery systems play a crucial role in modern therapeutics by enabling the direct administration of drugs into the systemic circulation, bypassing the gastrointestinal tract. These systems are particularly valuable for poorly absorbed oral medications that are unstable in the digestive environment or require rapid onset or sustained therapeutic levels. Delivery is achieved through intravenous, intramuscular, or subcutaneous routes, each selected based on the drug's properties...
