Significant Difference

Twenty five market skim milk powder samples obtained from various regions of Maharashtra were analysed for their chemical composition, physico-chemical properties and microbiological quality to access their suitability in terms of national and international standards. It was observed that the moisture, fat, protein, lactose and ash content of SMP samples obtained from various regions showed significant difference (P less than 0.05). It was also revealed that the scorched particle content, solubility index, dispersibility, wettability properties of samples varied significantly in different regions for different brands. Similarly, the NPN and true protein content in SMP samples of different regions were significantly different from each other. The average free fat content in the samples from Vidarabha was significantly higher than that of the other regions of the state. The titratable acidity and lactate content of various brands of SMP samples were ranged from 0.97-1.08 and 75-550 mg/100 g, respectively. It was observed that three brands out of twenty five samples were found positive for alkali neutralizers. Wide variation was observed in standard plate count and coliform counts of all the SMP samples of various brands collected from five different regions of Maharashtra.

A dietary supplement containing multifunctional ingredient sources was formulated and optimized for management of diabetes. The formulated dietary supplement comprised of milk fat and groundnut oil (90:10), whey protein concentrate, skim milk powder and sodium caseinate (50:25:25) and resistant starch and maltodextrin (70:30). The feasibility of the formulated dietary supplement in terms of physico-chemical, microbiological and sensory attributes was evaluated during storage period. The formulated supplement was found to have 4.37, 15.93, 10.15, 3.39 and 66.15 percent moisture, protein, fat, ash and carbohydrate respectively. It was observed that there was slight increase in moisture, free fatty acid, thiobarbituric acid and insolubility index while a decrease in dispersibility and sensory attributes (color and appearance, flavor, overall acceptability) during the storage period. However, the dietary supplement stored at room temperature indicated non-significant changes in all physico-chemical, microbiological and sensory parameters throughout the storage period of 180 days. Thus, dietary supplement prepared had better acceptability for a period of six months.

Twenty-five samples of spray dried whole milk powder (WMP) of different brands were procured from five regions of Maharashtra namely Vidarbha, North Maharashtra, Western Maharashtra, Marathwada and Mumbai. These samples were analyzed for the chemical composition, physico-chemical properties and microbiological quality to access their suitability in terms of national and international standards. The moisture, fat and protein content in WMP obtained from different regions varied significantly.Wide variation in the physical properties like scorched particles, wettability, dispersibility and solubility index was observed in WMP. The NPN, true protein content, titratable acidity and lactate content and free fat content of WMP samples were varied significantly. The standard plate count and coliform count of WMP samples were lower than that of the standard prescribed by BIS and PFA. In the present study except few, all the samples meet the requirements of national and international standards.

Non-fat yogurt exhibited weak body, poor texture, and whey separation because of reduction of fat. The separation of whey in yogurt is not desired by consumer. The aim of present study was to evaluate the effect of adding whey protein concentrate (WPC) and xanthan gum on physical, chemical and sensory properties of non-fat yogurt. Physical and chemical properties were tested using randomized block design whereas the yogurts properties during 21 days of cold storage included syneresis index and organoleptic. There were 6 treatments : A (full fat yogurt = control 1); B (skim milk + skim milk powder (SMP) 3% = control 2); C (skim milk + SMP 3% + WPC 1%); D (skim milk + SMP 3% + WPC 1,25%); E (skim milk + SMP 3% + WPC 0,5% + xanthan 0,005%); F (skim milk + SMP 3% + WPC 0,5% + xanthan 0,004%). The fat content 0,12%-0,14% of non-fat yogurt with the addition of WPC and blend of WPC-xanthan could increased firmness, cohesiveness and consistency compared to control 1 and control 2. In the organoleptic properties, non-fat yogurt with the addition of WPC and blend of WPC-xanthan were gained color, flavor, aroma, and consistency of the panelists preferred higher than control yogurt. Non-fat yogurt with only addition of WPC gained the lowest syneresis index. ABSTRAKYogurt tanpa lemak memiliki kekuatan struktur yang rendah dan rentan terjadi pemisahan whey karena berkurangnya kandungan lemak. Pemisahan whey pada yogurt tidak disukai oleh konsumen. Tujuan penelitian ini adalah untuk mengevaluasi efek penambahan whey protein concentrate (WPC) dan gum xanthan terhadap karakteristik fisik, kimia sensori yogurt tanpa lemak. Karakteristik fisik dan kimia diuji menggunakan metode RAK, sedangkan karakteristik yogurt selama penyimpanan dingin 21 hari meliputi indeks sineresis dan organoleptik. Terdapat 6 perlakuan yaitu: A (susu segar = kontrol 1); B (susu skim + skim milk powder (SMP) 3% = kontrol 2); C (susu skim + SMP 3% + WPC 1%); D (susu skim + SMP 3% + WPC 1,25%); E (susu skim + SMP 3% + WPC 0,5% + gum xanthan 0,005%); F (susu skim + SMP 3% + WPC 0,5% + gum xanthan 0,004%). Kandungan lemak 0,12%-0,14% pada yogurt tanpa lemak dengan penambahan WPC dan kombinasi WPC-gum xanthan dapat meningkatkan firmness, cohesiveness, dan konsistensi dibandingkan kontrol 1 dan kontrol 2. Secara organoleptik, yogurt tanpa lemak dengan penambahan WPC dan kombinasi WPC-gum xanthan mendapatkan tingkat kesukaan panelis lebih tinggi untuk warna, rasa, aroma, dan kekentalan dibandingkan yogurt lemak utuh tanpa perlakuan. Yogurt tanpa lemak dengan penambahan WPC saja mendapatkan indeks sineresis lebih rendah dibandingkan perlakuan lainnya.

Water Holding

The effect of different concentration of transglutaminase - TG (0.02%, 0.06% and 0.12%) on physico-chemical properties of probiotic yoghurt was investigated. Two series of yoghurt were manufactured on a laboratory scale from pasteurised skim milk (0.1 % w/w fat). Series I was produced with TGase activation during a period of 2 h at 40?C, while series II was produced without enzyme activation. Then, the adequate quantities of TGase and probiotic starter culture ABT-4 (Chr. Hansen A/S Denmark) were added. Chemical composition, physico-chemical properties (water holding capacity and whey separation) and sensory characteristics of yoghurt samples were determined after production and during 5 days of storage. Addition of TGase to milk (direct or after activation) for probiotic yoghurt manufacture improved its overall characteristics. Activation of TG in yoghurt production increases water holding capacity as well as decreases syneresis during the storage.

High protein yoghurt was made from whole milk, fortified with egg white (30% v/v) and skim milk powder at 12% (w/v). Different yoghurt mixes, with albumin content of 15%, 30% and 45% (v/v), were prepared. The control was made from whole milk, fortified with skim milk powder at 12% (w/v). The blended premixes were pasteurized at 74ºC for 4 seconds, cooled and then inoculated with 3% (w/v) Direct Vat Set yoghurt starter culture at 45ºC. After fermentation for 3 hours in a water bath maintained at 46+-1C, product was cooled to 5ºC and then stored for 24 hours. The effect of the fortification on physico-chemical and sensory properties was investigated. Protein content increased to 8.50% at 45% egg white utilization. Susceptibility to wheying was reduced in egg-white fortified samples, without signicant difference in sensory attributes of the test samples compared to the control. Sensory analysis showed that yoghurt fortified with 45% egg white was organoleptically acceptable. The yoghurt was rated as having better sensory appeal as compared to the control.
