The utilization of starter cultures is vital for dairy fermentation industries. Lactobacillus paracasei M104 and Pediococcus pentosaceus M103 have been isolated from goat milk and were demonstrated to acidify goat milk during fermentation. This study was conducted to compare the physicochemical and microbial qualities of goat milk fermented using these starter cultures either as a single starter or combined in goat milk. The treatments were L. paracasei M104 (Lp) and P. pentosaceus M103 (Pp) as single starter culture fermentation and combined (Lp/Pp) fermentation at a ratio of 1:1 at 6% inoculation (v/v). For control treatment, goat milk was fermented using yogurt starter, i.e., a combination culture of Streptococcus thermophilus and L. bulgaricus (St/Lb) at a ratio of 1:1 at 6% (v/v). The fermentation was performed by incubating the inoculated goat milk at 37°C for 18 h. The pH and degree of acidity were measured every 2 h during the fermentation process, whereas the physicochemical (pH, degree of acidity, lactose, protein, and viscosity) and microbial (total lactic acid bacteria/LAB) qualities were measured after the fermentation process. Data analysis revealed that the different starter cultures had no significant effect (P > 0.05) on the pH and degree of acidity, lactose and protein content, viscosity, and total LAB content. The goat milk fermented in this study had an average pH of 4.41 ± 0.11 and a degree of acidity of 1.26 ± 0.05%, a lactose content of 5.47± 0.80%, a protein content of 6.69± 1.52%, a viscosity of 1217 ± 395 cP, and a total LAB content of 9.57 ± 1.49 log CFU/mL. In conclusion, goat milk fermented using both single and combined starter cultures of L. paracasei M104 and P. pentosaceus M103 exhibited similar physicochemical and microbial qualities and required longer fermentation time compared with the control.

This study was conducted to evaluate the external physical quality and sensory quality of eggs fed diets added with purslane meal (Portulaca oleraceae) as a source of alpha-linolenic acids. The materials used were Hy-Line Brown laying hen (n= 150 hens, 54 weeks old). The design of the study was a one way classification with five experimental diets. Each diet was replicated five times with five hens for each replication. The diets were formulated by supplementing purslane meal to a basal diet. The levels of purslane meal were 0% (T0), 2% (T1), 4% (T2), 6% (T3), 8% (T4). The diets were given to the hens for 35 days with 7 days of adaptation period. To analyse the external quality of the eggs, a total of 30 eggs (n=6 per dietary treatment) collected at day 33, 34, and 35 were used. The sensory analysis used eggs from day 32. The results of the external quality of eggs showed that the addition of purslane meal (Portulaca oleracea) into the diets of laying hens reaching a level of 8% tended to increase egg weight and did not decrease shell thickness, shell weight, the shape index, and specific gravity (P>0.05). Dietary inclusion of purslane meal up to a level of 8% significantly increased (P<0.01) the preference of egg yolk color while texture, taste, flavor, and overall acceptance were not affected. The conclusion is that purslane meal can be included in the laying hen diets up to a level of 8% without decreasing the external physical quality and the sensory quality of boiled eggs. Diets containing purslane meal increase the preference of egg yolk color due to the increase in yolk color intensity.

The aims of this study were to investigate the potential of local ginger for natural antioxidants on full-fat mayonnaise. The used materials were sunflower oil, vinegar, egg yolk, white pepper, salt, sugar, mustard, and local ginger extract. The study was done by using laboratory experimental with Nested Completely Randomized Design with 2 factors and 3 replications. The first factor was used three ginger varieties, namely elephant ginger/(Zingiber officinale var. Roscoe) (G), red ginger (M)/(Zingiber officinale var. Rubrum) and emprit ginger (E)/(Zingiber officinale var. Amarum). The second factor was the addition levels, which were 0.5% (a), 1% (b) and 1.5% (c). The observed variables include pH, viscosity, moisture content and antioxidant activity (IC50). Data were analyzed by using analysis of variance. The result showed that the used different ginger material and different levels of addition did not give significant effect (P>0.05) on pH analysis and gave highly significant effect (P<0.01) of the antioxidant activity, viscosity and moisture content. The study could conclude that mayonnaise added with red ginger showed physicochemical properties better than added with emprit ginger and gajah ginger. In addition, the best result was found in 1.5% ginger addition of each ginger variety in terms of physicochemical qualities of the mayonnaise.

Casein is one of the major protein components in milk. Its functional properties allow casein to be preferred by the consumers. In addition, casein could be collected as bioactive compositions to be added to food. The purpose of this study was to observe the functional properties of casein added with catechin from cocoa husk in terms of emulsions, emulsion activity, foaming, solubility, and sedimentation. The treatment was carried out by using a completely randomized experimental design (CRD) method with five treatments of different catechin concentrations (control; 0.5%; 1,0%; 1,5%; 2%). The results of the study were analyzed with analysis of variance and followed with least significant difference (LSD) test. The different catechin concentrations gave a highly significant effect on emulsion stability, foaming and sedimentation and didn’t give a significant difference in solubility and emulsion activity between the five treatments. The best treatment in this research was at 2% catechin addition.

The process of making egg white powder would determine the qualities of the product. One way to maintain the qualities of the egg white powder could be done through egg white fermentation prior to drying. This research aims to understand the effect of Kluyveromyces lactis fermentation on egg white at different starter concentrations and fermentation time to the physicochemical and functional properties of the egg white powder. The research is conducted in a completely randomized design experiment with nested treatment. The K. lactis starter concentrations were divided into 3 groups (P1 = 0.2%; P2 = 0.4%; and P3 = 0.6%), and the fermentation times were divided into two groups (W1 = 12 hours; and W2 = 24 hours), with all treatments were repeated four times and nested on the starter concentration. The results showed that concentration K. lactis starter concentration and fermentation time did not give significant effect to the physicochemical and functional (pH, yield, solubility, water, ash, and carbohydrate content, and colours (L*, a*, b*)) properties, but increase the protein content of the egg white powder. The research concludes that egg white fermentation with 0.6% Kluyveromyces lactis concentration for 24 hours gave the best physicochemical and functional properties of the egg white powder.

Penelitian ini bertujuan untuk mengetahui pengaruh jenis dan proporsi tepung jagung terhadap sifat daya ikat air dan organoleptik dari nugget ayam kampung . Penelitian ini menggunakan rancangan acak lengkap faktorial yang terdiri atas 2 faktor. Faktor pertama ialah 5 (lima) jenis tepung jagung, yaitu: jagung kuning (J1); jagung pulen ( J2); jagung ungu (J3) ; jagung Provit A1 ( J4 ); dan jagung provit A2 ( J5 ). Faktor kedua adalah prosentase penggunaan tepung jagung terhadap berat daging ayam yang dipergunakan, yaitu 10% (T1); 20% (T2); 30% (T3) dan 40% (T4). Dari kedua faktor tersebut diperoleh 20 kombinasi perlakuan, dimana setiap kombinasi perlakuan diulang sebanyak 3 kali. Pengaruh perlakuan terhadap sifat daya ikat air dianalisis menggunakan analisis kergaman, dan dilanjutkan dengan uji beda nyata terkecil (BNT). Data kualitas organoleptik di analisis secara statistik deskriptif. Variabel yang diukur meliputi analisis sifat fisik daya ikat air , dan organoleptik , meliputi: warna, tekstur dan kekenyalan, cita rasa, dan penerimaan umum. Hasil penelitian menunjukkan, uji daya ikat air dari nugget ayam kampung berada pada kisaran 47,75 – 61,64%, dimana perlakuan J2T3 (jagung pulen taraf penggunaan 3 0 % ) memiliki prosentasi daya ikat air terrendah, sedangkan yang tertinggi pada perlakuan J5T4 (jagung provit A2 taraf penggunaan 40% ) . P enggunaan bahan pengisi dari ke lima jenis tepung jagung (J1, J2, J3, J4 dan J5) pada taraf 40 g (T1) diperoleh daya ikat air antara 50,02 – 55,36%. Hasil uji organoleptik terhadap nugget ayam kampung, menunjukkan bahwa kombinasi perlakuan J4T1 (jagung Provit A1 dengan taraf 10%) memperoleh nilai tertinggi untuk warna, tekstur, kekenyalan, dan cita rasa, dengan skor masing-masing 6,43 , 5,69 , 5,83 dan 5,86, sedangkan untuk kategori “penerimaan umum”, nilai tertinggi diperoleh pada perlakuan J5T3 (jagung Provit A2 dengan taraf 30%), dengan skor 6,00.

Penelitian ini menggunakan rancangan acak lengkap faktorial yang terdiri atas 2 faktor. Faktor pertama ialah 5 (lima) jenis tepung jagung, yaitu: jagung kuning (J1); jagung pulen ( J2); jagung ungu (J3) ; jagung Provit A1 ( J4 ); dan jagung provit A2 ( J5 ). Faktor kedua adalah prosentase penggunaan tepung jagung terhadap berat daging ayam yang dipergunakan, yaitu 10% (T1); 20% (T2); 30% (T3) dan 40% (T4). Dari kedua faktor tersebut diperoleh 20 kombinasi perlakuan, dimana setiap kombinasi perlakuan diulang sebanyak 3 kali. Pengaruh perlakuan terhadap sifat daya ikat air dianalisis menggunakan analisis kergaman, dan dilanjutkan dengan uji beda nyata terkecil (BNT). Data kualitas organoleptik di analisis secara statistik deskriptif. Variabel yang diukur meliputi analisis sifat fisik daya ikat air , dan organoleptik , meliputi: warna, tekstur dan kekenyalan, cita rasa, dan penerimaan umum. Hasil penelitian menunjukkan, uji daya ikat air dari nugget ayam kampung berada pada kisaran 47,75 – 61,64%, dimana perlakuan J2T3 (jagung pulen taraf penggunaan 3 0 % ) memiliki prosentasi daya ikat air terrendah, sedangkan yang tertinggi pada perlakuan J5T4 (jagung provit A2 taraf penggunaan 40% ) . P enggunaan bahan pengisi dari ke lima jenis tepung jagung (J1, J2, J3, J4 dan J5) pada taraf 40 g (T1) diperoleh daya ikat air antara 50,02 – 55,36%. Hasil uji organoleptik terhadap nugget ayam kampung, menunjukkan bahwa kombinasi perlakuan J4T1 (jagung Provit A1 dengan taraf 10%) memperoleh nilai tertinggi untuk warna, tekstur, kekenyalan, dan cita rasa, dengan skor masing-masing 6,43 , 5,69 , 5,83 dan 5,86, sedangkan untuk kategori “penerimaan umum”, nilai tertinggi diperoleh pada perlakuan J5T3 (jagung Provit A2 dengan taraf 30%), dengan skor 6,00.
