The researchers in the article \u201cEncapsulation of Lactobacillus acidophilus La-5 and Bifidobacterium Bb-12 by spray drying and evaluation of its resistance in simulated gastrointestinal conditions, thermal treatments and storage conditions\u201d, published in the Ci\u00eancia Rural<\/em> (vol. 48, no. 6), aimed to evaluate the influence of different drying temperatures on the spray dryer on Lactobacillus acidophillus<\/em> La-5 and Bifidobacterium<\/em> Bb-12. For this, they subjected these particles to temperatures of 110\u00baC, 120\u00baC, 130\u00baC and 140\u00baC and evaluated the viability of these particles, encapsulation efficiency, water activity and humidity. Secondly, the researchers subjected the microparticles with greater viability to analyzes of thermal resistance, gastrointestinal simulation, storage stability, morphology and particle size. They used as reference the literature reviews of Morgan, et al<\/em>. (2006) on preservation of microorganisms and Peighambardoust, et al<\/em>. (2011), in addition to the study by Pedroso, et al<\/em>. (2012) on encapsulation of Lactobacillus acidophillus<\/em> and Bifidobacterium<\/em>.<\/p>\n

According to the results, the drying temperature of 130\u00b0 C was the most efficient in the encapsulation of the particles. The microparticles of Lactobacillus acidophillus<\/em> presented greater survival in the evaluation of the thermal resistance and gastrointestinal simulation. These same particles remained viable in storage at all temperatures evaluated over the 120 days. Thus, they were more resistant than Bifidobacterium Bb-12 particles.<\/p>\n

Probiotic products have been prominent in the functional food market. For the researcher Cristiano de Menezes, the results of this study may contribute to the development of these products, since they bring important information about the resistance capacity of probiotics. “We have brought important data on the best temperature condition and the impact it has on the efficiency of microparticle encapsulation. Moreover, the study of probiotics on different conditions allowed to know their behavior for future applications in different food matrices”, he comments.<\/p>\n

Microencapsulation and probiotics have been studied by different researches, which seek to know the properties of these particles and to improve their development process. This study adds important information to this broad field of research, whose gaps need to be filled and clarified, according to Cristiano.<\/p>\n

The air inlet temperature of 130\u00b0C in the spray dryer provided greater encapsulation efficiency of the microparticles Lactobacillus acidophillus<\/i> La-5 and Bifidobacterium<\/i> Bb-12. In addition, this temperature also made the physicochemical characteristics more desirable in these particles, such as low water activity and humidity, which ensure better microbiological stability. …<\/span> Read More →<\/span><\/a><\/span><\/p>\n","protected":false},"author":209,"featured_media":52,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_monsterinsights_skip_tracking":false,"_monsterinsights_sitenote_active":false,"_monsterinsights_sitenote_note":"","_monsterinsights_sitenote_category":0,"footnotes":"","_links_to":"","_links_to_target":""},"categories":[3,20,12],"tags":[192,21],"class_list":["post-464","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-agricultural-sciences","category-cr","category-press-releases","tag-agronomy","tag-ciencia-rural"],"aioseo_notices":[],"_links":{"self":[{"href":"https:\/\/pressreleases.scielo.org\/en\/wp-json\/wp\/v2\/posts\/464","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/pressreleases.scielo.org\/en\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/pressreleases.scielo.org\/en\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/pressreleases.scielo.org\/en\/wp-json\/wp\/v2\/users\/209"}],"replies":[{"embeddable":true,"href":"https:\/\/pressreleases.scielo.org\/en\/wp-json\/wp\/v2\/comments?post=464"}],"version-history":[{"count":3,"href":"https:\/\/pressreleases.scielo.org\/en\/wp-json\/wp\/v2\/posts\/464\/revisions"}],"predecessor-version":[{"id":466,"href":"https:\/\/pressreleases.scielo.org\/en\/wp-json\/wp\/v2\/posts\/464\/revisions\/466"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/pressreleases.scielo.org\/en\/wp-json\/wp\/v2\/media\/52"}],"wp:attachment":[{"href":"https:\/\/pressreleases.scielo.org\/en\/wp-json\/wp\/v2\/media?parent=464"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/pressreleases.scielo.org\/en\/wp-json\/wp\/v2\/categories?post=464"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/pressreleases.scielo.org\/en\/wp-json\/wp\/v2\/tags?post=464"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
