This absorption response will later be related to physical properties of probiotic drink. The Observations in the infrared region used Bruker ATR Alpha FTIR Spectrometer while the observations in the UV and visible light region used Thermo Scientific Evolution 220 UV-Visible Spectrophotometer. The measuring time was done until there is a change in probiotic drink absorption. The measurement results obtained were in the form of the transmittance spectrum of the wavelength. Measurements in the infrared region showed some probiotic drink content such as protein at ∼6123 nm, lactose at ∼9532 nm, and glucose at wave number ∼1100-800 cm-1. In the UV region, it is related to the reduction amount of protein while visible light region was associated with changes in the constituent particles of probiotic drink along with changes in pH. All observations refer to the literature. The results of this observation certainly do not represent all the contents of probiotic drink but this method can also be utilized for freshness detection of other similar drinks that contain milk.[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Author keywords” size=”size-sm” text_align=”text-left”][vc_column_text]FT-IR-spectrometers,Infrared regions,Optical characteristics,Scientific evolution,Transmittance spectra,UV and visible light,UV-visible spectrophotometer,Visible light region[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Indexed keywords” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Funding details” size=”size-sm” text_align=”text-left”][vc_column_text]The study of Optical Characteristic Properties of Probiotic drink Drink Using Spectrophotometer UV/Vis and FTIR supported by Indonesia Endowment Fund for Education (LPDP), The Ministry of Finance Republic of Indonesia and Faculty of Mathematics and Natural Science, Bandung Institute of Technology.[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”DOI” size=”size-sm” text_align=”text-left”][vc_column_text]https://doi.org/10.1088/1742-6596/1245/1/012084[/vc_column_text][/vc_column_inner][vc_column_inner width=”1/4″][vc_column_text]Widget Plumx[/vc_column_text][/vc_column_inner][/vc_row_inner][/vc_column][/vc_row][vc_row][vc_column][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][/vc_column][/vc_row]
