It was tried to microencapsulate erythritol as a phase change material with the interfacial polycondensation reaction method by using the (W/O) emulsion and to characterize the microcapsules prepared. In the experiment, toluene diisocyanate, diphenyl methane diisocyanate and hexamethylenediisocyanate were used to form the polyurethane shell and the effects of them on the heat storage density an...

Microencapsulation of substances applied on textiles is a relatively new method with many advantages applied in many different fi elds. There are many effective approaches to microencapsulation for decreasing release of fragrances and active substances such as essential oils and cosmetic ingredients using cyclodextrins, yeast cells, chitosans, melamine-formaldehyde or poly(L-lactide) as wall ma...

Microencapsulation as one of the most modern methods has considerable effects on probiotic survival. In this study Lactobacillus casei (ATCC 39392) and Bifidobacterium bifidum (ATCC 29521) were encapsulated using calcium alginate-gelatinized starch, chitosan coating and inulin via emulsion technique, and were incubated in simulated gastric juice (along with pepsin, pH=1.5) and simulated intesti...

background microencapsulation is a useful method to prolong a drug release from dosage forms and to reduce its adverse effect (1) among various available methods. the microencapsulation of hydrophilic active ingredients requires the use of a polar dispersing phase such as a mineral oil. acetone/paraffin systems are conventionally used. objectives the current study aimed to investigate two diffe...

Core/shell SiO2 and (RSiO1.5)(1-x)-(SiO2)x (R = alkyl) microcapsules were synthesized via a single-step O/W emulsion system using a self-templating method; the facile synthetic process provides an in-situ encapsulation route for a wide range of lipophilic functional compounds.

Microencapsulation is a technology that has increasing application in animal nutrition. This provides the possibility to protect sensitive compounds through feed process and storage conditions. Furthermore, of this technique affords increase bioavailability mask unpalatable taste. Different are consider for microencapsulation include certain vitamins, amino acids, fatty organic acids live micro...

We describe a new technique for microencapsulation with high-mannuronic acid (high-M) alginate crosslinked with BaCl(2) without a traditional permselective component, which allows the production of biocompatible capsules that allow prolonged survival of syngeneic and allogeneic transplanted islets in diabetic BALB/c and NOD mice for >350 days. The normalization of the glycemia in the transplant...

Bioactive compounds are naturally derived chemical having distinct biological activities and pronounced effects on human health. Dairy products offer a great way to incorporate these substances create functional food items which able cater the needs of consumers. fortification has been getting lot attention, especially in dairy foods like probiotic yogurts, butter, cheese, ice cream, other ferm...

Essential fatty acids play an important role in promoting brain development, decreasing the incidence of cardiovascular diseases, and reducing inflammation. However, they are inherently unstable susceptible to oxidative deterioration due two or more double bonds their structure. Delivery systems have been developed provide effective encapsulation protection for sensitive acids, thus fulfilling ...

ABSTRACT: The availability of different food products containing bioactive compounds promotes their inclusion in the daily diet consumers. However, effective and safe delivery such requires certain precautions to ensure preservation, stability, bioavailability when consumed. Microencapsulation is a great alternative, which method capable protecting compounds, including probiotic cells, prebioti...
