Evaluation on Performances of Yoghurt Used Modern Technology Versus Natural One

. A research for studying performances (aromatics including colour, taste, smell, texture and its financial benefit) of milk products i.e. yoghurt which used modern technology versus the natural one was conducted at PT Prima Rasa, Denpasar. The research consisted of two treatments (A = modern technology and B = natural technology). The objective of the research were: 1) to study the differences of aromatic and financial benefit of yoghurt with modern technology versus the natural one, 2) to use as a reference in the future on milk products business, and 3) to increase the quantity and quality of yoghurt and income per capita in the Bali Island. In this research, yoghurt production which used modern technology (treatment A) used some ingredients i.e. fresh milk, skimmed milk, starter (imported Lactic Acid Bacteria from Canada) and modern equipments i.e. electric incubator for milk fermentation. While the natural technology (treatment B) used a slightly different ingredients and equipments i.e. non imported starter and non electric incubator (ampel bamboo). The starter used was lactic acid bacteria naturally found in the ampel bamboo as incubator at once. The incubator was covered with aged banana leaf on the fermentation processes. These ingredients and equipments were very easy to find, available through the year and cheap. There were six replicates in each treatment. Data obtained were analyzed with t test and financial benefit was analyzed descriptively. Results of the research showed that yoghurt aromatics which used natural technology was 14.29% significantly higher than modern one but its texture was 20.31% or significantly lower. The differences did not seem to cause difference on the taste between them. The average taste score was the same (7.1), indicating that both treatments had the same taste. The financial benefit of the natural yoghurt was much higher (90.74%) than that of the modern one (127.40% versus 10.80%).
