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.

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.

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.

Whole Process

In this research, shrimp waste was fermented with 3 species of symbiotic lactic acid bacteria, namely Streptococcus thermophilus, Lactobacillus acidophilus and Lactobacillus bulgaricus. The ingredient changes occurring in the fermentation process were investigated. Results showed that the production of lactic acid in the fermentation process was remarkably improved, with the pH decreasing rapidly to 4.25 within 8 h, the lowest pH reaching 3.22, and the titratable acidity reaching 25.0 mmol/100ml. The improved acidic environment promoted the removal of calcium and protein, with 91.3% calcium, 97.7% protein and 32.3% carotenoid removed from shrimp waste after 168 h fermentation. The putrefaction was effectively prevented and the TVBN level was low throughout the whole process. Glucose was consumed rapidly in the earlier phase of the fermentation; about 69.4% glucose was consumed in the initial 24 h. The consumption of glucose was in well accordance with the growth of lactic acid bacteria, the removal of calcium and the increasing of titratable acidity. The amino nitrogen content kept increasing within 48 h, thereafter it came to decrease. 88.4% of peptides in the hydrolysate ranged between 1000 ~ 10000 Da, 10.2% smaller than 1000 Da, and 3.44% larger than 10000 Da.
