Indonesian Food and Nutrition Progress, is a primarily online, a peer-reviewed journal in food technology and nutrition. All papers should focus on the novelty of the research carried out. It is published by Indonesian Association of Food Technologists in collaboration with Faculty of Agricultural Technology, Gadjah Mada University. This journal is published two times a year which is a continuation of the last publication in 2005. The journal is devoted to a rapid peer reviewed full-length original research paper, short communications, and critical reviews, which serves as an international forum for the exchange of information in all aspects of food technology and nutrition. Food and Nutrition Progress includes a wide range of food technology and nutrition topics such as: Physical, chemical, biotechnological, microbiological, process engineering, analytical, and nutritional aspects; Post-harvest technology; Sensory evaluation; Diet plans; Gastronomy; Food safety and hygiene; Functional foods; Novel foods.

Comparative Study of CaSO4 and Papain Enzyme as Coagulants in The Tofu Production Windy Rizkaprilisa; Setiadi Setiadi
Indonesian Food and Nutrition Progress Vol 15, No 2 (2018)
Publisher : Indonesian Association of Food Technologists

Tofu is a high protein food which is widely consumed in Indonesia. In this study, we used the variety of coagulant which is CaSO4 and papain enzymes. The extraction of soybean protein was conducted using selected ratio (1:2), then coagulated using two different coagulant which are CaSO4 (1 and 2 gram) and papain enzyme (3 and 6 gram). The highest yield of tofu used CaSO4 2 gram with 66% yield and papain enzyme 6 gram with 65% yield. This indicates that more of coagulant are used so more yield of tofu. Based on the proximate test, especially proteins showed the making of tofu with papain enzyme (9.29%) gave higher protein content than CaSO4 (6.50%) as coagulant.Keywords: Tofu, soybean, CaSO4, papain enzyme

Probiotic (Lactobacillus casei) Encapsulation Using the Method of Spray Drying with Combined Prebiotic from Iles-Iles (Amorphopallus oncophyllus) and Protectant Agent (Skim Milk, Gum Arabic, Maltodextrin) Aloysius Prima Cahya; Meidi Syaflan; Ngatirah Ngatirah

The aims of this research were to know the effect of combine iles-iles (refined starch, whole iles-iles flour, and refined glucomannan) as encapsulating agent (capsule materials) and different protectant agents to get microcapsule synbiotic, which have the highest number of probiotic cells and high viability against low pH and bile salt. Design blocks complete with factorial design was used in the experimental design. The first factor was capsule materials with a concentration of 10% consisting of three material types: A1 (refined glucomannan), A2 (refined starch), and A3 (Iles-iles native). The second factor was protectant, protecting the probiotic bacteria during spray drying, used at concentration of 5% consisting of three substances i.e. B1 (skim milk), B2 (maltodextrin), and B3 (gum arabic). Using protectant agents on the MRS for the growth of L. casei resulted no effects against the numbers of LAB (lactic acid bacteria), density, moisture content, and hygroscopicity; however, it had influence on yield and solubility. The best use based on the reduction of LAB numbers were flour and gum Arabic which was significant compared to other fractions.Keywords: iles-iles, glucomannan, starch, protectant agent, symbiotic LAB

Monitoring of Pollution of Salmonella sp. in Raw Milk Using Virulence Gen Marker Stefanie Yolanda Liwan; Tri Yahya Budiarso

Salmonella sp. is an enteropathogenic organism and it can spread through contaminated food which is rich in nutrition such as raw milk. The goal from this research is to find out the suitable pasteurization and time effect on the growth isolates Salmonella sp. that its invA presence is detected. Seventy-five (75) samples were taken in three locations of milk collection from groups of breeders. 10 ml of milk samples were grown in enrichment culture of modified Tryptic Soy Broth (mTSB) at 37oC for 12 hours. Cellular culture was then grown in differential selective medium of Salmonella Shigella Agar (SSA) and Chromocult Coliform Agar (CCA). From 75 milk samples produced 1392 colonies of typical Salmonella sp. pathogens. Then, isolates were selected using Triple Sugar Iron Agar (TSIA) and Urea Broth media, producing 3 suspected isolates of Salmonella sp which was known from colonies color. Results of confirmation using API 20E and 50 CHE produced two isolates of Salmonella spp. with %ID = 99.6% and one isolate of Salmonella typhi with %ID = 72.1%. All of the isolates were then detected for virulence factor using invA marker and all positive isolates have virulence factor. It indicates that raw milk contains polluted pathogenic bacteria.Keywords: raw milk, enteric pathogenic, virulence gen

Milkfish that have been seasoned with some spices then cooked by a high -cooker produced a fish product which has soft spines and bones. The product which has a local name bandeng presto has been popular in Indonesia due to the product is tasty and it is easier to be consumed directly after it is prepared as a dish. The storage life of bandeng presto is relatively short, which is due to deterioration process by microbes after processing. Consequently, this condition can retard the products distribution. The aims of the research are to understand is there any significant influence of differing the drying time (0 hours and 4 hours) of milkfish cooked by a high-pressure cooker by using an electric oven (50oC) and storage period at room temperature (5 days) and also to find out which treatment produce the best product quality. The results showed that the treatment of differing the drying period gave a highly significant influence (P <0.01) on the sensory value and the moisture content but did not gave significant influence (P >0.05) on the number of bacteria colonies. The length of storage period gave a highly significant influence (P <0.01) on the sensory value between the products which were dried for 4 hours and without drying treatment but only the drying process for 4 hours gave a highly significant influence (P <0.01) on the moisture content, the water activity and the number of bacteria colonies. The quality of the products that were dried for 4 hours were better and their storage life can reach up to 3 days compared to the products that were not dried.Keywords: Milkfish, high pressure cooker, drying, oven, quality, storage life

Review: Prevention and Reduction of Mycotoxin by Antagonistic Microorganism Winiati Pudji Rahayu
Indonesian Food and Nutrition Progress Vol 15, No 2 (2018)
Publisher : Indonesian Association of Food Technologists

Mycotoxin is widely known as one cause of foodborne disease, produced by toxigenic fungi. Any country should be aware about this high risk potency by knowing the mycotoxin, affected commodities, fungal sources, and toxicity effect to human or animal. Controlling mycotoxin could be done by physic, chemical, and biological methods. The microbial characteristic used for biological agent should be evaluated including the inability to produce toxic substance, tendency to multiply, colonize, survive, safety, and applicability to the environment. Studies related to mycotoxin biocontrol by using antagonistic microorganism can be focused on (1) the effect to the mycotoxin, (2) the growth of microorganism, or (3) the application to food both raw material and processed products. Consideration to combine more than one species of microorganism instead of a single species also has been taken to achieve more effective result. For example, S. cerevisiae has been used together with LAB to control certain mycotoxin. Further studies are needed to develop the possibility of other biological agents and the effect of their application, which in the next have the potency as manufacturing products.
