Resumo: | More than 50% of the world population presents conditions of lactase deficiency, in Brazil, 58 million people undergo such genetic disorder. The goal of the present work was to produce probiotic yogurt with reduced contend of lactose added flaxseed oil and to study the viability of lactic and bifid bacteria compared to the flaxseed oil and different contends of lactose. Three out of the seven developed treatments were added with 0,2; 0,5 and 0,8g of lactase enzyme per liter of milk respectively. Microbiological and physic-chemical analysis were carried out in the yogurts. The yogurts with reduced lactose presented a decrease in pH and an increase in the acidity less strong than the other yogurts during twenty-eight days of storage. The contends of lactose found in the yogurts which were added with lactase are considered low, within the patterns and regulations of the for special dietary uses legislation. The ratio found between Streptococcus salivarius ssp. Thermophilus and Lactobacillus delbrueckii ssp. bulgaricus was 2:1, which favors the decrease of postacidification. The number of viable cells of Bifidobacterium sp. and Lactobacillus acidophilus as well as the lactic bacteria stood until the end of the storage period according to the recommendations of the legislation. The fat contends were higher in yogurts added with flaxseed oil and rice flour concomitantly. Only one of the yogurts fit the legislation concerning protein contend, probably due to the substitution of powder milk by the rice flour in the yogurts. Considering the results it is possible to infer that the enzyme lactase used in the experiment efficiently hydrolyzed the lactose of the yogurts and did not compromised the viability of microorganisms of the traditional culture as the probiotic culture. |

O objetivo deste trabalho foi o de produzir iogurte probiótico com teor reduzido de lactose e adicionado de óleo de linhaça e estudar a viabilidade das bactérias lácticas e bífidas frente ao óleo de linhaça e diferentes teores de lactose. Três dos sete tratamentos desenvolvidos foram adicionados de 0,2; 0,5 e 0,8g de enzima lactase por litro de leite respectivamente. Foram realizadas análises microbiológicas e físico-químicas nos iogurtes. Os iogurtes com reduzidos teores de lactose apresentaram queda de pH e aumento de acidez menos acentuada que os demais iogurtes em vinte e oito dias de armazenamento. Os teores de lactose encontrados nos iogurtes com adição de lactase são considerados baixos, dentro dos padrões regulamentados pela legislação de alimentos para fins especiais. A relação encontrada entre Streptococcus salivarius ssp. thermophilus e Lactobacillus delbrueckii ssp. bulgaricus foi de 2:1 favorecendo a diminuição da pós-acidificação. O número de células viáveis de Bifidobacterium sp. e Lactobacillus acidophilus assim como o de bactérias lácticas se mantiveram até o final da estocagem conforme preconizado na legislação brasileira. Os teores de gordura foram maiores para os iogurtes adicionados de óleo de linhaça e farinha de arroz concomitantemente. Apenas um dos iogurtes apresentou-se de acordo com a legislação quanto ao teor de proteínas, provavelmente pela substituição do leite em pó pela farinha de arroz na formulação dos iogurtes. Considerando os resultados obtidos pode-se inferir que a enzima lactase utilizada hidrolisou eficientemente a lactose dos iogurtes e não comprometeu a viabilidade dos microrganismos da cultura tradicional como da cultura probiótica.application/pdfporUniversidade Federal de Santa MariaPrograma de Pós-Graduação em Ciência e Tecnologia dos AlimentosUFSMBRCiência e Tecnologia dos AlimentosIogurteProbióticoLactoseÓleo de linhaçaYogurtProbioticLactoseFlaxseed oilCNPQ::CIENCIAS AGRARIAS::CIENCIA E TECNOLOGIA DE ALIMENTOSIogurte probiótico com teor reduzido de lactose adicionado de óleo de linhaçaProbiotic yogurt with reduced lactose content with flaxseed oilinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisRichards, Neila Silvia Pereira dos Santoshttp://lattes.cnpq.br/0618653776990780Rodrigues, Rosane da Silvahttp://lattes.cnpq.br/9182448088756765Fries, Leadir Lucy Martinshttp://lattes.cnpq.br/5099404254254292http://lattes.cnpq.br/3541023974722818Becker, Larissa Vargas5007000000064005003003005006698fb34-e594-4cf4-a9c3-f688b9a456c3857b9f03-8ab4-49ac-8d63-53882b5ad8e88f4f5de2-07f4-478f-a896-e09438d4f999259ee132-f44e-4af7-a95c-683d87867435info:eu-repo/semantics/openAccessreponame:Manancial - Repositório Digital da UFSMinstname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMORIGINALBECKER, LARISSA VARGAS.pdfapplication/pdf590350http://repositorio.ufsm.br/bitstream/1/5666/1/BECKER%2c%20LARISSA%20VARGAS.pdf17052cc0c8bed47778ea0d8ccdb2db05MD51TEXTBECKER, LARISSA VARGAS.pdf.txtBECKER, LARISSA VARGAS.pdf.txtExtracted texttext/plain202028http://repositorio.ufsm.br/bitstream/1/5666/2/BECKER%2c%20LARISSA%20VARGAS.pdf.txtfb5fe8be339512466d54a8ff57c77196MD52THUMBNAILBECKER, LARISSA VARGAS.pdf.jpgBECKER, LARISSA VARGAS.pdf.jpgIM Thumbnailimage/jpeg4964http://repositorio.ufsm.br/bitstream/1/5666/3/BECKER%2c%20LARISSA%20VARGAS.pdf.jpg097c18d5cda35bdc4ace874a43b1a798MD531/56662023-04-12 08:51:46.178oai:repositorio.ufsm.br:1/5666Repositório Institucionalhttp://repositorio.ufsm.br/PUBhttp://repositorio.ufsm.br/oai/requestopendoar:39132023-04-12T11:51:46Manancial - Repositório Digital da UFSM - Universidade Federal de Santa Maria (UFSM)false |
