Frozen Yogurt

O leite de cabra é recomendado para pessoas intolerantes ao leite de vaca e/ou portadoras de desordens gastrintestinais. frozen yogurt elaborado a partir de iogurte de leite de cabra foi acrescido de 1% de prebiótico (inulina), 0,25% de cultura starter (Streptococcus thermophilus e Lactobacillus bulgaricus) e 0,25% de cultura probiótica (Bifidobacterium animalis e Lactobacillus acidophilus) para verificar seu potencial probiótico (após sete e 120 dias de armazenamento), sua qualidade físico-química e sua aceitação sensorial. Durante a estocagem, houve redução de células viáveis da flora microbiana, principalmente dos probióticos. Ainda assim, o produto apresenta potencialidade probiótica pela soma de B. animalis e L. acidophilus atingir o mínimo desejável até o fim do armazenamento. Os valores de extrato seco total (26,6±0,2%), proteína (3,0±0,2), gordura (2,6±0,1%), pH (5,5±0,01) e ácido láctico (0,2±0,01%) encontram-se semelhantes aos relatados em outros trabalhos para o mesmo produto. A avaliação sensorial foi realizada por 50 provadores não treinados em teste com escala hedônica de sete níveis e intenção de compra. O produto recebeu bons escores para aparência global, cor, aroma e sabor; já textura e sabor residual obtiveram menores índices de aceitação. Na intenção de compra, 61% dos avaliadores declararam que comprariam o produto, contra 39% que não comprariam. Nessas condições, demonstra-se a viabilidade de elaboração de frozen yogurt de leite caprino acrescido de pre- e probióticos.

Male Swiss mice, implanted with Ehrlich ascites tumor cells, were fed each of the following test materials: fresh bovine colostrum, colostrum cultured with Lactobacillus acidophilus, colostrum cultured with Lactobacillus bulgaricus, colostrum cultured with L. bulgaricus and Streptococcus thermophilus, milk cultured with L. acidophilus and milk cultured with L. bulgaricus. Fresh colostrum had no significant effect when fed ad libitum for 7 consecutive days after tumor implantation. Colostrum fermented with L. acidophilus, L. bulgaricus or yogurt culture significantly (P< 0.05) inhibited tumor cell proliferation as indicated by a 16 to 40% decrease in cell counts and a 13 to 35% decrease in DNA synthesis. Similar effects were noted for whole milk fermented with either L. acidophilus or L. bulgaricus.

Soybean is a functional food and it is characterized by providing several beneficial health effects allowing the expansion of research and development of functionalized products as alternative substitutes of dairy products. This study aimed to elaborate frozen yogurt enriched with calcium and added a mixed culture containing Lactobacillus acidophilus, Bifidobacterium and Streptococcus thermophilus microencapsulated, from aqueous extract of soybean. The micelles were prepared from albumin and collagen with the addition of over activated probiotic culture. The frozen yogurt was prepared on the basis of aqueous extract of soybean. The micelles of albumin and collagen were able to protect the probiotic microorganisms from cold keeping them viable for storage. The micelles were able to obtain a product with adequate physical, chemical and sensory characteristics for an edible frozen, what shows that soy frozen yogurt may be a good choice of product for the market.

Currently, the food industry wants to expand the range of probiotic yogurts but each probiotic bacteria offers different and specific health benefits. This study examined the viable counts of Lactobacillus acidophilus and percentage syneresis of probiotic yoghurt produced from reconstituted skim and whole milk powder stored for 35 days at 4±2 oC. Skim milk probiotic yoghurt (SMPY) and Whole milk probiotic yoghurt (WMPY) were produced by reconstituting dry milk powder (130 g/900 ml w/v), which was pasteurized at 85 oC for 15 mins, cooled to 43 oC and inoculated with freeze dried probiotic yoghurt mixed starter culture containing Streptococcus thermophilus (ST), Lactobacillus bulgaricus (LB) and Lactobacillus acidophilus (LA). The yoghurt samples were analyzed for viability of ST, LB, LA and also syneresis. During storage, the viable counts of ST in SMPY decreased from 5.43x108 to 5.18x106 cfu/ml, LB (2.47x108 to 8.10x105 cfu/ml) and LA (1.83x108 to 5.78x105 cfu/ml). Similarly, the viable counts of ST in WMPY decreased significantly from 5.40x108 to 5.15x106 cfu/ml, LB (2.43x108 to 7.82x105 cfu/ml) and LA (1.80x108 to 5.84x105 cfu/ml). Although the mean viable counts of the LA decreased during storage, both SMPY and WMPY still contained an average of 1.48x106 cfu/ml of probiotic cells up to 28 days of storage, which is above the “therapeutic minimum” of 106 cfu/ml. The percentage syneresis of SMPY and WMPY increased significantly during the 35 days of storage, from 24.4-32.0 % and 24.8-32.7 % respectively. There was a positive correlation between storage time and syneresis thus affecting the texture. In conclusion, yoghurt made from either skim or whole milk powder can be used as an adequate carrier of LA (probiotic bacteria) up to a period of 28 days at 4±2 oC and a stabilizer should be used to reduce the separation of whey and thus maintain the texture.

AbstractNovel functional food products might be an easy accessible and eligible approach to help reduce the risk of severe viral infections including SARS-CoV-2. Hence a product containing probiotics, propolis and cinnamon was developed and interferences of the ingredients were characterized. Yogurts were prepared using starter cultures with propolis (0.03%) and cinnamon in various concentrations (0.3%, 1%, and 2.5%). Bifidobacterium animalis ssp. lactis, Lactobacillus acidophilus, Streptococcus thermophilus, and Lactobacillus delbrueckii subsp. bulgaricus were used as microorganisms for yogurt production. Chemical analysis revealed a decline of fat matter in the presence of propolis and/or cinnamon. Propolis had statistically significant suppressive effects on Bifidobacterium animalis ssp. lactis as well as on Lactobacillus delbrueckii subsp. bulgaricus numbers (p < 0.05). These effects were diminished in the presence of increasing cinnamon concentrations. For Lactobacillus acidophilus a statistically significant reducing effect on the number of colonies was observed in all products investigated. Nevertheless all samples met the standard of recommended level of ≥ 106 viable cells/g of a product. Propolis showed an inverse effect on Streptococcus thermophilus by increasing its colony numbers in yogurts. The probiotic yogurt samples containing propolis (0.03%) and cinnamon (2.5%) gained the highest number of points in the sensory evaluation compared to control.

Resumo Consumidores têm demonstrado mais atenção à qualidade e à funcionalidade dos alimentos consumidos em razão do aumento da incidência de doenças inflamatórias intestinais, cardiovasculares, hipertensão arterial, diabetes mellitus II, obesidade, cânceres, principalmente aquelas relacionadas à intolerância à lactose e à alergia às proteínas do leite bovino e da soja. Neste estudo, de forma inédita, foram elaboradas e caracterizadas bebidas probióticas à base de extrato de arroz. As bebidas fermentadas com extrato de arroz (BA) foram desenvolvidas com a inoculação de microrganismos Lactobacillus acidophilus, Streptococcus thermophilus e Bifidobacterium animalis ssp. lactis, adoçadas com diferentes tipos de substratos, como sacarose, glicose e mel, e caracterizadas por análises físico-químicas e microbiológicas. Menos tempo de fermentação (nove horas) foi alcançado com a adição do inóculo SAB 440 (Lactobacillus acidophilus, Streptococcus thermophilus e Bifidobacterium animalis ssp. lactis) e da glicose e mel como substratos nas bebidas de extrato de arroz. Todas as bebidas foram caracterizadas como probióticas porque a contagem de células viáveis foi superior a 106 UFC mL-1. Cabe ressaltar que o valor energético pode se enquadrar como baixo, tendo o conteúdo lipídico sido inferior a 0,03%, o que classifica essas bebidas fermentadas como livres de gordura, de acordo com a legislação brasileira vigente. A funcionalidade de bebidas fermentadas elaboradas pode ser atribuída principalmente à sua característica probiótica. As bebidas desenvolvidas são interessantes para o consumo por pessoas intolerantes à lactose e alérgicas a leite de bovino e soja, pois contêm ingredientes não lácteos.

Syzygium Cumini

Radikal bebas bersifat reaktif yang menyebabkan penyakit degeneratif sehingga tubuh memerlukan antioksidan eksogen. Salah satu contohnya adalah buah Jamblang (Syzygium cumini (L)) yang memiliki aktivitas antioksidan tinggi karena antosianin alaminya.. Antosianin bersifat lebih stabil dalam suasana asam sehingga cocok jika ekstrak buah jamblang difortifikasi dalam sediaan yoghurt. Yoghurt merupakan produk fermentasi susu yang menggunakan bakteri asam laktat yaitu: Streptococcus thermophilus, Lactobacillus bulgaricus, Lactobacillus acidophilus. Tujuan penelitian ini untuk mengetahui kadar antosianin ekstrak buah jamblang pada formulasi yoghurt dengan konsentrasi 0%, 5%, 7,5% dan 10% serta syarat mutu SNI. Pengujian meliputi uji sifat fisika, kimia dan mikrobiologi yaitu sensoris, viskositas, kadar asam, kadar lemak, dan jumlah starter bakteri, serta uji stabilitas yoghurt dengan penyimpanan pada suhu 4°C dan uji total antosianin pada hari ke-1, ke-7, ke-14, 21 dan hari ke-28. Hasil penelitian menunjukkan bahwa kadar antosianin total pada formula yoghurt terfortifikasi ekstrak buah jamblang pada konsentrasi 10% (60.87±2.24 mg/L) menghasilkan stabilitas antosianin lebih baik, sesuai dengan persyaratan SNI.
