  2. About me • Master in Food Technology with Sensory Science

    specialization, Wageningen University and Research • Expertise in Advance Sensory Methods and Sensometrics, data analysis, and R programming • Founder of Sensolution.ID • [email protected]
  3. Sensory Science ~ Food + Consumer Perception Sensory food research

    aims to reach a better understanding of how the senses respond to food and eating, but also how our senses can be used in quality control and product design. - WUR Sensory Science Food science and technology Marketing and Consumer behavior Nutrition & Health
  4. Quantitative (attribute based) Affective Qualitative (not attibute based) Profiling Checklist

    Specified Discrim. tests Unspecified Discrim. Tests Holistic Preference Profiling + hedonic Acceptance Scale-based Non scale-based • QDA • Free-choice profiling • Flash profiling • Just-about-Right (JAR) • Ideal Profile Method (IPM) • Check-all-that-Apply (CATA) • Temporal Dominance of Sensation (TDS) • 2 Alternative Forced Choice (2AFC) • 3 Alternative Forced Choice (3AFC) • Specified Tetrad • Duo-Trio • Triangle • Tetrad, • Two-out-of-Five • Sorting • Napping • Word association • Paired preference • Ranked preference Credits: Betina Piqueras-Fiszman
  5. Why do we need another tool? Think of features! Think

    of learning curve! Think of affordability!
  6. Features • Based on R statistical language • Free/Libre Open

    Source Software (FLOSS) • Works in clouds, no installation required • Covers discriminative, descriptive, affective sensory methods (21+ methods) • Includes both conventional and rapid sensory methods • Available in Bahasa Indonesia
  7. Features Experimental setup Design of experiments, Panel performance analysis Discriminative

    test 2-Alternatives Force Choice (2AFC), 3-Alternatives Force Choice (3AFC), Duo-Trio, Triangle, Tetrad, Hexad, Two- out-of-Five Descriptive test Quantitative Descriptive Analysis (QDA), Flash Profiling (FP), Free-Choice Profiling (FCP), Rate-all-that-Apply (RATA), Check-all-that-Apply (CATA), RATA as CATA, Sorting Task, Napping Affective test Acceptance test, Paired Preference, Multiple Paired Preference, Preference Ranking, Hedonic Rating Optimisation Just-about-Right (JAR) method
  8. Evaluation • 35 participants (bachelor, master, and doctorate students) •

    QDA dataset (12 perfumes, 103 panelists, 21 sensory descriptors) • 10 questions about data analysis and interpretation • 11 questions about user experience • Time was recorded
  9. Participants Total number of participants 35 subjects Gender 85.71% Female,

    14.29% Male Age Average 25.89 years old, in range of 20-52 years old Education level 62.86% Bachelor, 28.57% Master, 8.57% Doctorate Analytical software ever used 8.57% MS.Excel, 85.71% Minitab, 2.85% PanelCheck, 25.71% SPSS, 8.57% XLSTAT
  10. List of questions Q1 How many panellists participated in the

    study? Q2 Please list the samples that tested in the study. Q3 What are the sensory descriptors used to evaluate the sample? Q4 How many sensory descriptors show significant difference between sample? (P<0.05) Q5 How many sensory descriptors do not show significant difference between sample? (P<0.05) Q6 Please indicate the four sensory descriptors that are most discriminative. Q7 Which sample has the highest intensity in ‘woody’? Q8 How many dimensions or principal components are extracted from Principal Component Analysis (PCA)? Q9 How much is the cumulative frequency of the first three dimensions or principal components? Q10 Which samples have closest sensory characteristic similarity with L’instant?
  11. List of questions Q11 How easy is it to import

    a dataset? Q12 How easy is it to set up the parameters? Q13 How easy is it to get basic information about the imported dataset? Q14 How intuitive is the user interface? Q15 How quick is the computation speed? Q16 How concise is the output of the statistical analysis? Q17 How understandable is the output of the statistical analysis? Q18 How easy is it to transfer the results into another document (word document, excel document, etc)? Q19 How good is the quality of the basic plots/graphs produced? Q20 How suitable is the application/software for sensory analyses? Q21 Please indicate the overall score for this application/software.
  12. • Superior in features compared to the software currently being

    used • Conveys better user experience • Significantly quicker • Available in Bahasa Indonesia Benefits and limitations • Requires internet access • Documentations are not yet completed • Evaluation only carried out for QDA methods • Only one statistical software included for comparison
