Critical Reviews in Food Science and Nutrition
|November 8, 2021
Summary
New food-grade delivery systems protect sensitive probiotics. These systems, like "silkworm cocoons" and "spider webs," enhance probiotic survival and pave the way for innovative functional foods.
Area of Science:
- Food Science and Technology
- Microbiology
- Biomaterials Engineering
Background:
- Probiotics offer significant health benefits, driving demand for advanced probiotic functional foods.
- Ensuring probiotic viability through harsh food processing and storage conditions is a critical challenge.
- Development of effective, food-grade delivery systems is essential for maximizing probiotic efficacy.
Approach:
- This review categorizes novel probiotic delivery vehicles into two main types: "silkworm cocoons" (particles, emulsions, beads, nanofibers, microcapsules) and "spider webs" (hydrogels, bigels).
- Comparative analysis of the merits and drawbacks of various delivery systems is presented.
- Recent advancements in encapsulating sensitive probiotics are summarized.
Key Points:
- "Silkworm cocoon" systems utilize protective outer layers for probiotics.
- "Spider web" systems employ network structures for probiotic protection.
- Both approaches aim to enhance probiotic stability and survival rates.
Conclusions:
- Future prospects include improved probiotic viability, targeted delivery, and co-delivery of multiple strains.
- Further scientific validation and diversification of food products incorporating these delivery systems are anticipated.
- Probiotic delivery vehicles are becoming integral to food science, with ongoing development for enhanced human health applications.

Body:Improving a drug's stability in the gastrointestinal (GI) tract is paramount for enhancing its bioavailability and therapeutic effectiveness. Various strategies are employed to protect the drug from the harsh gastric milieu and to ensure its release and absorption at the desired site within the GI tract.Polymer coatings are one such method used to shield drugs from the stomach's acidic environment. By preventing premature drug release, these coatings improve the bioavailability of unstable...

01:18Drug Delivery: Enteral Route
852
The enteral drug administration involves three primary routes: oral, sublingual, and buccal. Oral ingestion is the most prevalent, safe, economical, and convenient method for drug administration. However, it has certain drawbacks, including limited absorption due to the drug's low water solubility or poor membrane permeability, possible emesis from GI mucosa irritation, destruction of drugs by digestive enzymes or low gastric pH, and irregular absorption along with food or other drugs.

Body:Bioavailability is a critical pharmacological concept that measures the extent and rate at which an active drug ingredient or therapeutic moiety enters the systemic circulation, remaining unchanged. It's a pivotal factor in determining a drug's efficacy and safety.The Biopharmaceutics Classification System (BCS) plays an essential role in drug development by categorizing drugs into four classes based on their solubility and permeability. This classification aids in understanding drug...

01:16Drug Delivery: Overview
466
The selection of a drug's delivery route depends upon its physicochemical properties, including lipid or water solubility and ionization, as well as the therapeutic requirement, such as immediate or sustained effect. These routes can be divided into three primary categories: enteral, parenteral, and topical.
Enteral delivery involves administering drugs directly through swallowing, sublingual placement, or buccal application. Orally administered drugs predominantly navigate the...

Microorganisms play a fundamental role in vaccine development, gene therapy, and therapeutic production. Their biological properties are harnessed to advance medicine and public health. Beyond immunization, microorganisms contribute to gut health, antibiotic synthesis, and genetic disease treatment.Live Attenuated and Inactivated VaccinesLive attenuated vaccines, such as the measles, mumps, and rubella (MMR) vaccine, utilize weakened forms of pathogens to closely resemble natural infections.
