White oyster mushrooms and tofu can used as an alternative raw materials in making sausage. Red bean flour can substitute for skim milk because it is high nutritional. The aimed of the research was to determine the best formulation of sausage with white oyster mushroom and tofu, also the addition of red bean flour and skim milk, which based on highest protein content, also level of preference. The experimental design was a completely randomized design (CRD) with the first factor was variation oyster mushrooms and tofu (75% : 25%, 50% : 50%, 25% : 75%) and the second factor was variation of red bean flour and skim milk (1:3, 2:2, 3:1). The result indicated that the best formulation of sausage made from oyster mushroom and tofu with the addition of the red bean flour and skim milk based on the best protein content and highest preference of panelist were treatment of 75% of oyster mushrooms : 25% of tofu, and the addition of red bean flour:skim milk 3:1 with moisture content 60.53%, ash content 2.99%, protein content 15.88%, fat content 6.45%, and carbohydrate content 14.14%. Organoleptic analysis was color 4.09 (dark), flavor of mushroom 3.41 (quite felt), flavor of tofu 2.25 (less felt), savory taste 3.94 (tasty), chewy 3.29 (quite) and overall, 3.33 (preferred)

Tropical almonds (Terminalia catappa L) are food ingredients that can be developed into probiotic drinks like yogurt. The addition of celery leaf extract in to yoghurt can affect the growth of the bacteria. Celery leaf contain natural antimicrobial compounds that can influence bacterial growth. However, celery also contain bioactive compounds that can improve the functional properties of food. This study aimed to determine the antioxidant activity of tropical almond yogurt with the addition of celery leaves. The research method used was factorial Completely Randomized Design (CRD), with the first factor being the type of starter culture and the second factor the fermentation time (0, 2, 4, 6, 8, 12, and 16h). The starter culture included Lactobacillus bulgaricus (Lb), Streptococcus thermophilus (St), and Lactobacillus bulgaricus - Streptococcus thermophilus (St-Lb). Data analysis used Duncan Multiple Range Test with a significance level of 5%. The results showed that after 16h of fermentation, the total acid-producing bacteria was at 7.47 log CFU/ml. This value met the standard criteria for probiotics products. Antioxidant activity with the highest percentage of inhibition (97.11%) was found in yogurt with a starter type of St-Lb. This product had 7.21 log CFU/ml of total acid-producing bacteria, total phenol content (TPC) of 143.61 mg GAE/ 100 ml, total flavonoids of 281.22 mg QE/g, a total sugar content of 25.76%, and protein content of 13.38%. Tropical almond yoghurt, with the addition of celery leaves, has the potential to be developed as a functional food. Further research need to investigate the functional properties of the yoghurt.

Jambal roti is a fermented product of sea catfish (Arius thalassinus) with the manufacturing process uses a high salt concentration (30%), and is still done traditionally. High salt in fish processing causes consumers to hesitate in consuming the product. The fish fermentation process involves several bacteria, including lactic acid bacteria, which will break down fish protein into other compounds that affect the chemical and microbiological characteristics of the product. This study aims to analyze the effect of supplementation of the variation of salt content (20%, 25% and 30%) and the indegenous lactic acid bacteria (control, Lactobacillus plantarum, Pediococcus acidilactici and Pediococcus pentosaceus) on the chemical and microbiological characteristics of the jambal roti. The results showed that the 25% salt content with Lactobacillus plantarum supplementation had the best characteristics among the other treatments, namely the number of coliform bacteria (2,11 log cfu / gram) and Salmonella-Shigella (2,18 log cfu / gram) the least among others treatments, total bacteria (7,26 log cfu/gram) and total lactic acid bacteria (4,58 log cfu/gram). Chemical characteristics includes moisture content 32,53%, ash content 23,08% wb, Aw 0,67, fat content 1,74% (w / b), NaCl content 18,10% and total protein 35,11%..

Edible film merupakan lapisan tipis yang memiliki fungsi untuk melapisi makanan atau membungkus makanan. Edible film harus aman karena terkadang edible film merupakan bagian dari makanan. Kimpul mempunyai potensi yang baik sebagai bahan dasar pembuatan edible film karena kandungan amilosanya yang tinggi. Salah satu fungsi edible film adalah untuk memperpanjang masa simpan sehingga apabila suatu edible film mempunyai kemampuan sebagai antimikrobia, akan memberikan nilai lebih. Penelitian ini bertujuan untuk menentukan kemampuan ekstrak jahe dalam menghambat pertumbuhan mikroba pada edible film pati kimpul dan menentukan karakteristik edible film pati kimpul dengan penambahan ekstrak jahe. Penelitian ini dilakukan dengan menggunakan Rancangan Acak Lengkap (RAL) faktorial. Faktor pertama adalah konsentrasi ekstrak jahe (10, 15, dan 20%) sedangkan faktor kedua yaitu jenis jahe (Gajah, Emprit, dan Merah). Hasil penelitian terbaik diperoleh dari perlakuan konsentrasi ekstrak jahe 20% dan jenis Jahe Merah didasarkan pada hasil pengujian antimikroba terbaik. Pada perlakuan ini dihasilkan kadar air edible film 11,70%%, ketebalan 0,09 mm, kuat tarik 1,1 MPa, zona hambat terhadap E.coli 1,1 cm, zona hambat terhadap S. aureus 1,6 cm.
