Viscosity and Proteolysis of Yoghurt Using ROPY Strains, in the Presence of Bifidobacteria, as Compared to Those of Soyogburt

ABSTRACT: Yoghurt from cowmilk. (YVB) and soyoghurt from soymilk (YSB) were manufactrured by itIDoculations of mixed cultures using 2 or 1 ropy strains, in the presence of Bifidobacterium subsp. The first mixed culture was consisted of Streptococcus thermophilus St!, Lactobaci/lw~ delbrueckii subsp, bulgarius Lb5, both arc ropy strains, and Bifidobacterium sub...p. B 20. The second was consisted of the strains St. 3, Lb 6 (ropy strain), and B-20. Viscosity and proteolysis of products along the time of incubation have bcen detected in this study. Viscosity of soyoghurt\u27s products were higher titan those of yoghurt (

Carry-over of aflatoxin B1-feed into aflatoxin M1-milk in dairy cows treated with natural sources of aflatoxin and bentonite

High occurrence of aflatoxin contamination in feed stuffs implicates for a long time experience of aflatoxin B1 (AFB1) exposure to dairy cattle in Indonesia. A latin square 4X4 research design was adopted to study the characteristic of AFB1 carry-over rate (COR) of Indonesian crossbred Friesian Holstein (PFH) as effects of inclusions of AFB1-naturally contaminated feed and bentonite in the diet. Results showed a rapid aflatoxin M1 (AFM1) excretion in the milk, detected in the first milking sample or 10 hours after AFB1 ingestion. The steady state of AFM1 concentration observed since the first day of treatment period and AFM1 contamination was still detected until 5 days after AFB1 removed from the diet. The COR in this study was observed 0.1%. AFM1 concentration was highly significantly (P0.05) of levels of AFB1 and bentonite inclusions on the COR, nutrients intake, milk production, and milk composition. IIt is concluded that AFM1 concentration was influenced by AFB1 intake and that transfer of AFB1-feed into AFM1-milk (COR) in PFH cow was lower compare to reported COR value for dairy cow in sub tropical region

THE EFFECT OF THREE CULTURES OF LACTIC ACID BACTERIA AND LENGHT OF STORAGE ON CHEMICAL COMPOSITION AND FLAVORS OF CHEESE

The objective of the research was to study of LAB- containing cheeses as compared to those of control without addition of cultures and ripening length three months at 7 0 C. Completely Randomize Design was performed to see the effect of treatment (supplementation of LAB-cultures and ripening length) on water content, protein level, fat level , organic acids and flavor note and score, completed by Duncan's Multiple Range Test for further analyses. The results of research have indicated that there were no significantly different, due to the treatment, in water, and fat contents, but significantly different (P<0,05) on protein content, and very significantly different on lactic and pyruvic acid. While the ripenning time of cheese has no role in water content, but it has significantly affected (P<0,05) on protein, and fat content and highly significant on lactic acid content (P<0,01). The acidity of treated product was higher than those of control, but ripening time has decreased it, and flavor note of entrained consumers has indicated that ripenned LAB containing-cheese got the highest score (1.96/4) Keywords: Cheese, Lactic Acid bacteria, Length of Ripenning, Biochemical Composition, Flavo

Air and water qualities around small ruminant houses in Central Java - Indonesia

There is a general concern that livestock can have a profound effect on the environment, also in smallholder production systems. This paper presented the impact of small ruminants on the quality of air and water in and around small ruminant houses. In total, 27 small ruminant houses from the three agro-ecological zones, lowlands, middle zone and uplands, in the Province of Yogyakarta, Indonesia, were monitored to investigate gas emissions and water pollution. Air samples were taken by using a gas catching tool filled with absorbents for gases. The gases mainly consisted of ammonia, nitrogen oxides, dihydrogen sulphide, sulphur dioxide and hydrocarbons. Groundwater samples were collected from the farmers¿ wells, adjacent to the small ruminants houses. The main water chemical parameters analysed were pH, turbidity, iron, fluoride, calcium carbonate, chloride, manganese, nitrate, nitrite, dihydrogen sulphide, and organic matter, while the bacterial indicators were faecal coliform and total coliform. Gas concentrations in the air were highest inside the houses, while around the houses their concentrations decreased rapidly on both the tailwind and headwind side. The concentrations of the gases were below the admissible levels assessed by the local government, except hydrocarbons in the middle zone, which was probably related to the storage of the manure inside the houses. The impact of small ruminants on water pollution was much greater than on air pollution. Some of the physico-chemical parameters showed high concentrations and nearly reached the admissible limit. The water sources had very high levels of faecal coliform bacteria and total coliform bacteria, two groups of bacteria used as indicators for water contamination caused by manure. It can be concluded that, in Central Java, management and housing of small ruminants close to the family quarters causes little environmental problems; however, attention should be paid to water qualit
