Abstract

Komposisi yang terkandung pada susu merupakan indikator dalam menilai kualitas susu segar. Pemeriksaan kualitas susu sangat penting karena berbagai alasan yang berkaitan dengan kesehatan masyarakat, kepuasan konsumen, dan keberhasilan komersial produk susu.  Penelitian ini dilakukan untuk mengetahui perbedaan metode pengujian protein (Bradford dan Titrasi  formol) pada susu segar terhadap kadar protein, lama analisis, dan biaya. Materi yang digunakan pada penelitian ini adalah sampel susu sapi segar yang diperoleh dari 30 ekor sapi perah. Variabel yang diukur yaitu kadar protein, lama analisis dan biaya yang dibutuhkan untuk setiap metode analisis protein. Data dianalisis menggunakan analisis deskriptif, dan uji T. Nilai kadar protein yang diperoleh dengan metode Bradford berkisar  antara 1,81 - 2,74% dan Titrasi  formol antara 2,2 - 3,7%. Rataan kadar protein dengan metode Bradford 2,23±0,26% dan titrasi  formol 2,96±0,43%. Waktu analisis yang dibutuhkan pada metode Bradford 17 menit dan titrasi  formol  5,15 – 5,6 menit. Rataan waktu dengan metode  Bradford 17±0 menit dan titrasi  formol 5,37±0,12 menit sedangkan biaya yang dibutuhkan pada metode Bradford 2.000,00 Rupiah/sampel dan titrasi  formol 1.164,55-1.170,88 Rupiah/sampel. Rataan biaya yang di butuhkan pada metode Bradford 2.000,00±0 Rupiah/sampel dan Titrasi  formol 1.167,76±1,82 Rupiah/sampel. Hasil Uji T menunjukkan bahwa pengujian kadar protein menggunakan metode Bradford dan titrasi  formol berbeda nyata (P<0,05) terhadap kadar protein, lama analisis dan biaya. Pengukuran kadar protein dengan metode titrasi  formol memberikan hasil yang lebih sensitif terhadap kadar protein susu segar lebih cepat dan biaya analisis lebih murah.

Abstract

This study aims to evaluate the effect of the addition of carrot powder, dragon fruit, secang wood, and telang flowers on the physicochemical and sensory characteristics of milk ice cream. A Complete Random Design (CRD) with four treatments and five repeats was used to observe color, overrun, pH, melting time, texture, and organoleptic parameters. The results show that the addition of natural ingredients has a significant influence on several parameters. Colour and texture showed noticeable differences, with the carrot (P1) treatment having high lightness (62.39±3.89) and with secang wood (P3) treatment having high hardness (509.34 N), while dragon fruit (P2) was preferred in organoleptic tests. Overrun and melting time don't show any noticeable difference (p > 0.05), but overall values are below home industry ice cream standards. The addition of natural ingredients such as dragon fruit and telang flower lowers the pH, influenced by the anthocyanin content. In conclusion, natural ingredients can improve the visual characteristics and sensory preferences of ice cream, but it need optimization to meet industry quality standards.

Abstract

This study investigated the characteristics of concentrated yogurt made from goat milk with the addition of black rice extract. The inclusion of black rice extract aimed to provide a source of antioxidants and natural coloring, as it is rich in flavonoids, particularly anthocyanins. The primary materials used in this research were goat milk, a dry yogurt starter, and black rice extract. The experiment was conducted in several stages: preparation of black rice extract, yogurt production, and concentrated yogurt production. A randomized complete block design (RCBD) was employed, with treatments involving varying levels of black rice extract (0%, 2%, 4%, and 6%), each treatment repeated five times. The yogurt starter, containing probiotic lactic acid bacteria (Bifidobacterium longum, Lactobacillus rhamnosus, Lactobacillus casei, Lactobacillus helveticus, Lactobacillus bulgaricus, Lactobacillus acidophilus, and Streptococcus thermophilus), was used to facilitate the fermentation of milk into yogurt. Parameters measured included yield, pH, total titratable acidity, instrumental color indices (L*, a*, b*, whiteness index, hue, and chroma), total phenolic compounds, antioxidant activity, total lactic acid bacteria (LAB), texture, and proximate composition (moisture, ash, fat, and protein content). The addition of black rice extracts up to 6% resulted in higher protein and total lactic acid bacteria levels compared to the control. Additionally, black rice extract improved the color characteristics of concentrated yogurt made from goat milk.and gastrointestinal tract development in broiler chickens.

Abstract

Background. The objective of this reserch was to determine the effect of adding colostrum on kefir with different percentages of organoleptic properties. Material and methods. This study used a randomized block design (RBD) method using 1700 ml cow milk, 300 ml cow colostrum, and 40 g kefir seeds into 4 treatments tested by 25 semi-trained panelists. The treatment applied was the difference in cow colostrum namely K1 = 0% cow colostrum, K2 = 10% cow colostrum, K3 = 20% cow colostrum, K4 = 30% cow colostrum.The parameters observed were organoleptic properties of aroma, taste, texture and overall. The study was conducted on January 1-2, 2019 at the Laboratory of Animal Product Technology, General Soedirman University Faculty of Animal Husbandry. Results. The results showed that the addition of cow colostrum to kefir had no significant effect (P > 0.05) on aroma, had a significant effect (P< 0.05) on taste, texture and overall. The highest average is ranked 1 for the results of a typical kefir aroma with a value of 0.17, slightly sour taste with a value of 0.21, thick texture with a value of 0.42, and overall very like with a value of 0.29. Conclusion. The conclusion is that the addition of 30% cow colostrum can increase the taste slightly acidic, the texture is thicker and is preferred overall (overall), but can only increase the distinctive aroma of kefir in addition to cow colostrum 20%.

Abstract

Background. The research was conducted with the aim of knowing the use of vegetable pectin with different percentages of the color and texture of cow's milk yogurt sensoryly. Materials and methods. The material used is 5 liters of cow's milk cow milk from BBPTU-HPT Baturraden, Yogourmet dried yogurt starter, skim milk and 10 grams of vegetable pectin. The research method was an experiment with a randomized block design (RBD), with 4 treatments, with a total of 30 panelists. Results. The results showed that the use of pectin with different percentages in making cow's milk yogurt significantly affected the color of yogurt (P <0.01) and the texture of yogurt also had a very significant effect (P <0.01). The use of pectin with different percentages in the manufacture of cow's milk yogurt has a color average of P0: 0.58, P1: 0.40, P2: -0.406, P3: -049, P4: -0.35. The use of vegetable pectin with different percentages in making cow's milk yogurt has a mean texture of PO: -0.52, P1: 0.33, P2: -0.17, P3: 0.29, P4: 0.73. Conclusion. The use of pectin up to 0.8% in making yogurt increases the yellowish color and increasingly thick texture.
