2010 - Approaches for enhancing the viability of probiotics: a review

S. Sarkar  - British Food Journal, Vol. 112 Iss: 4, pp.329 - 349

Purpose – The purpose of this article is to attempt to highlight various approaches for enhancing the viability of probiotics, with special emphasis on micro-encapsulation. Design/methodology/approach – Various techniques, such as selection of acid and bile resistant strains, use of oxygen impermeable packaging materials, two-step fermentation, stress adaptation, inclusion of micro-nutrient, sonication of bacteria and micro-encapsulation, which could be employed for maintaining or enhancing probiotic viability are discussed, with special emphasis on micro-encapsulation. Findings – Probiotics lose their viability during gastro-intestinal transit due to unfavorable intestinal environment. Amongst diverse techniques micro-encapsulation could confer protection to the probiotics both in the product as well as in the gastro-intestinal environment. Originality/value – The paper shows that micro-encapsulation of probiotics renders them stable both in the product as well as in the intestinal environment and application of encapsulated probiotics would result in a product with greater prophylactic activities.
2010 - Microencapsulation techniques, factors influencing encapsulation efficiency

N. Venkata Naga Jyothi1, P. Muthu Prasanna, Suhas Narayan Sakarkar, K. Surya Prabha, P. Seetha Ramaiah1, G. Y Srawan - Journal of Microencapsulation 2010, Vol. 27, No. 3 , Pages 187-197

Microencapsulation is one of the quality preservation techniques of sensitive substances and a method for production of materials with new valuable properties. Microencapsulation is a process of enclosing micron-sized particles in a polymeric shell. There are different techniques available for the encapsulation of drug entities. The encapsulation efficiency of the microparticle or microsphere or microcapsule depends upon different factors like concentration of the polymer, solubility of polymer in solvent, rate of solvent removal, solubility of organic solvent in water, etc. The present article provides a literature review of different microencapsulation techniques and different factors influencing the encapsulation efficiency of the microencapsulation technique.
2010 - Therapeutic applications of cell microencapsulation

Grace J. Lim, Shirin Zare, Mark Van Dyke and Anthony Atala - Advances in Experimental Medicine and Biology, 2010, Volume 670, 126-136

In the past several decades, many attempts have been made to prevent the rejection of transplanted cells by the immune system. Cell encapsulation is primary machinery for cell transplantation and new materials and approaches were developed to encapsulate various types of cells to treat a wide range of diseases. This technology involves placing the transplanted cells within a biocompatible membrane in attempt to isolate the cells from the host immune attack and enhance or prolong their function in vivo. In this chapter, we will review the situation of cell microencapsulation field and discuss its potentials and challenges for cell therapy and regeneration of tissue function.
October 2010 - Encapsulation of polyphenols – a review

Zhongxiang Fang and Bhesh Bhandari - Trends in Food Science & Technology Volume 21, Issue 10, October 2010, Pages 510-523

Research on and the application of polyphenols, have recently attracted great interest in the functional foods, nutraceutical and pharmaceutical industries, due to their potential health benefits to humans. However, the effectiveness of polyphenols depends on preserving the stability, bioactivity and bioavailability of the active ingredients. The unpleasant taste of most phenolic compounds also limits their application. The utilization of encapsulated polyphenols, instead of free compounds, can effectively alleviate these deficiencies. The technologies of encapsulation of polyphenols, including spray drying, coacervation, liposome entrapment, inclusion complexation, cocrystallization, nanoencapsulation, freeze drying, yeast encapsulation and emulsion, are discussed in this review. Current research, developments and trends are also discussed.
October 2010 - HYDROGELS: A REVIEW

Anisha Singh, Pramod Kumar Sharma, Vipin Kumar Garg, Garima Garg - International Journal of Pharmaceutical Sciences Review and ResearchVolume 4, Issue 2, September – October 2010; Article 016

Polymers play a vital role in pharmaceutical development. Efforts have been continuously made to search a polymer that act in a
controlled and desired way. Hydrogel development has solved many such issues. This article deals with the fundamental and some
recent advances made in the fabrication and design criteria of hydrogel based drug delivery.
