About
Captures crucial information regarding the chemical composition and derived quality characteristics of tofu preserved using formalin. The objective of gathering this data is to facilitate the analysis of chemical components, specifically various gas levels and temperature, to establish a link with the resulting aroma and quality of the preserved food product. It serves as an essential resource for developing robust models capable of predicting tofu quality based purely on chemical measurements.
Columns
The dataset contains nine distinct features, primarily measuring gas concentrations in parts per million (ppm) and temperature:
- H2_MQ2(ppm): Measures the detected hydrogen levels in ppm.
- LPG_MQ2(ppm): Measures Liquified Petroleum Gas levels in ppm.
- CO_MQ2(ppm): Measures carbon monoxide levels in ppm.
- Alcohol_MQ2(ppm): Measures alcohol levels in ppm.
- Propane_MQ2(ppm): Measures propane levels in ppm.
- CH4_MQ4(ppm): Measures methane levels in ppm.
- Smoke_MQ4(ppm): Measures smoke levels in ppm.
- Temperature(C): Records the temperature of the tofu in degrees Celsius.
- label: The target variable indicating the aroma quality of the preserved tofu.
Distribution
The dataset is structured as tabular data, typically provided in a CSV file format. It contains 45,000 valid records across nine columns. The file size is approximately 1.42 MB. Note that there are no missing or mismatched values across the provided features. The mean hydrogen level is 1.52, while the mean carbon monoxide level is notably higher at 3.32.
Usage
This data product is ideally suited for:
- In-depth analysis of chemical components affecting food quality after preservation.
- The development of machine learning models for classification, aimed at accurately predicting the aroma quality of preserved tofu.
- Exploratory Data Analysis (EDA) focusing on the relationship between volatile chemical levels and perceived food characteristics.
Coverage
The data focuses entirely on intrinsic chemical composition and physical measurements (temperature) related to the preserved tofu product. Information regarding the geographic origin, specific time range of collection, or demographic details is not included in this collection.
