CATA(Check-All-That-Apply)「選擇適合分析法」是一種感官評估方法，廣泛應用於食品和飲料的品評中，特別是在咖啡評估領域。這種方法讓受試者從預定的描述詞彙列表中選擇所有適用於他們所品嚐或感受到的產品特性的詞彙，從而收集他們對產品的主觀感知。在CVA咖啡價值評估中，CATA描述詞通過標準化的詞彙列表，評估者可以更客觀地記錄咖啡的香氣、風味、餘味、酸度、甜度和口感等特性，提供全面且一致的感官統計數據。
CATA (Check-All-That-Apply) is a sensory evaluation method widely used in the assessment of food and beverages, especially in the field of coffee evaluation. This method allows participants to select all applicable descriptors from a predetermined list that best describe the characteristics they perceive in the product. In the CVA (Coffee Value Assessment), CATA descriptors are provided in a standardized vocabulary list, allowing evaluators to objectively record characteristics such as aroma, flavor, aftertaste, acidity, sweetness, and mouthfeel of the coffee, providing comprehensive and consistent sensory statistical data.
CATA的研究背景
CATA方法源於2007年Adams等人的研究，旨在通過感官屬性列表讓評估者選擇適用的屬性，以快速描述樣品特性。2012年，Valentin等人進一步指出，CATA問題可以由受訓或未受訓的評估者選擇，以便全面描述樣品的感官屬性。
The CATA method originated from a 2007 study by Adams et al., which aimed to quickly describe sample characteristics by having evaluators select applicable attributes from a sensory attribute list. In 2012, Valentin et al. further noted that CATA questions can be answered by both trained and untrained evaluators to provide a comprehensive description of a sample's sensory attributes.
使用CATA問題進行快速感官分析，旨在描述熱或冷食品或飲料隨溫度變化的感官屬性。CATA問題包含一系列感官屬性詞彙，受訓或未受訓的評估者選擇適用於每個樣品的所有屬性。雖然CATA僅產生二元結果(選中或未選中)，但對於未受訓的消費者小組使用時，CATA顯示出高區別能力，並產生與專業描述性感官分析相似的結果。此外，CATA被認為易於理解、重現性高，適合大規模消費者評估。CATA方法允許評估者快速選擇適用的屬性，從而描繪出感官屬性隨溫度變化的整體圖景。這一特點使得CATA在熱或冷食品和飲料的溫度範圍內應用時，能夠有效捕捉感官屬性的變化。
Using CATA questions for rapid sensory analysis aims to describe the sensory attributes of hot or cold food and beverages as they change with temperature. CATA questions include a series of sensory attribute descriptors, and evaluators, whether trained or untrained, select all applicable attributes for each sample. Although CATA only produces binary results (selected or not selected), it has shown high discriminative power when used with untrained consumer panels and yields results similar to those of professional descriptive sensory analysis. Additionally, CATA is considered easy to understand, highly reproducible, and suitable for large-scale consumer evaluations. The CATA method allows evaluators to quickly select applicable attributes, providing an overall picture of sensory attributes as they change with temperature. This feature makes CATA effective in capturing sensory attribute changes across temperature ranges in hot or cold food and beverages.
CATA的優點
受試者只需勾選適用的詞彙，操作簡單、無需專業訓練即可進行評估。在CVA中使用CATA描述詞，不用完全憑空構想感官詞彙。CATA詞彙來自咖啡風味輪的主要風味與次要風味，比較細緻的風味沒有列在CATA列表中。能夠同時評估多個感官特性，提供全面的咖啡感官描述。通過標準化的詞彙列表，減少不同受試者之間的變異性。受試者在較短時間內完成評估，適合大規模消費者感官測試。標準化的評估流程提高了結果的一致性和可重複性。
Participants only need to check applicable descriptors, making it simple to use and requiring no professional training for evaluation. In CVA, using CATA descriptors eliminates the need for evaluators to create sensory vocabulary from scratch. CATA terms are derived from the main and secondary flavors of the coffee flavor wheel, with finer nuances not listed in the CATA list. It enables the simultaneous evaluation of multiple sensory attributes, providing a comprehensive sensory description of the coffee. The standardized vocabulary list reduces variability between different evaluators. Evaluations can be completed in a short time, making it suitable for large-scale consumer sensory testing. The standardized evaluation process enhances the consistency and reproducibility of results.
如何使用CATA
1. 準備詞彙列表：根據產品特性準備一份全面的描述詞彙列表。這些詞彙應涵蓋所有可能的感官特性，例如香氣、風味、口感等。
2. 設計測試：讓受試者品嘗或感受產品，並勾選所有適用的描述詞彙。通常會準備一個包含多個描述詞彙的表格，讓受試者在品嘗或感受產品後進行勾選。
3. 數據收集和分析：統計受試者選擇的詞彙，分析每個詞彙被選中的頻率。這些數據能夠提供產品的綜合感官特性，幫助理解受試者對產品的感知。
1. Prepare the Vocabulary List: Prepare a comprehensive list of descriptive terms based on the product's characteristics. These terms should cover all possible sensory attributes, such as aroma, flavor, mouthfeel, etc.
2. Design the Test: Have participants taste or experience the product and check all applicable descriptors. Typically, a form containing multiple descriptive terms is prepared for participants to check off after tasting or experiencing the product.
3. Data Collection and Analysis: Collect and analyze the frequency of selected terms by the participants. This data provides a comprehensive sensory profile of the product and helps in understanding how the participants perceive it.
在CVA咖啡價值評估中的應用
Application of CATA in CVA Coffee Value Assessment
在咖啡價值評估中，CATA方法可以幫助記錄咖啡的多方面感官特徵，如香氣、風味、餘味、酸度、甜度和口感等。使用標準化的描述詞彙，可以更客觀地比較不同咖啡樣品之間的差異。
In coffee value assessment, the CATA method helps record various sensory characteristics of coffee, such as aroma, flavor, aftertaste, acidity, sweetness, and mouthfeel. Using standardized descriptive terms allows for a more objective comparison of different coffee samples.
CATA方法在CVA(Coffee Value Assessment)系統中的應用體現了其在專業評估中的價值。CVA系統是一個綜合性評估框架，旨在全面評估咖啡的各個方面，包括物理特性、感官描述、感官情感印象和外在屬性。CATA作為感官描述評估的一部分，提供了一種標準化的方法來記錄和分析受試者對咖啡特性的感知。
The application of the CATA method in the CVA (Coffee Value Assessment) system reflects its value in professional evaluation. The CVA system is a comprehensive evaluation framework designed to assess all aspects of coffee, including physical characteristics, sensory descriptions, sensory emotional impressions, and external attributes. CATA, as part of sensory descriptive evaluation, provides a standardized method for recording and analyzing participants' perceptions of coffee characteristics.
在CVA系統中，CATA方法被用來確保感官描述的準確性和一致性。通過使用標準化的詞彙列表，評估者可以更客觀地記錄咖啡的香氣、風味、餘味、酸度、甜度和口感等特性，這些統計數據有助於更全面地理解和評估咖啡的品質。此外，CATA方法的簡單性和高效性，使得它在大規模測試中特別有用，能夠快速收集大量數據，這對於市場調研和消費者偏好分析具有重要意義。

CATA與傳統杯測表的差異
Differences Between CATA and Traditional Cupping Forms
CATA和傳統杯測表在方法和用途上有顯著差異。CATA方法要求品評者從一個預定的描述詞彙列表中選擇所有適用的詞彙，這使得評估過程簡單且不需要專業訓練，有助於全面收集受試者對產品特性的感知，並且可以快速統計和分析感官數據。而傳統杯測表則更為詳盡，要求品評者對咖啡的多個特性(如香氣、風味、酸度、體脂感等)進行逐一評分，並給出總體評價。傳統杯測表需要專業知識和經驗來準確評估各項特性，因此更為複雜和專業。CATA方法更適合於快速、大規模的消費者感官測試，而傳統杯測表則主要用於專業的咖啡品質評估和交易。
CATA and traditional cupping forms differ significantly in both method and application. The CATA method requires tasters to select all applicable descriptors from a predetermined list, making the evaluation process simple and requiring no professional training, which helps in comprehensively collecting participants' perceptions of the product characteristics, and quickly tabulating and analyzing sensory data. On the other hand, traditional cupping forms are more detailed and require tasters to individually score multiple characteristics of coffee, such as aroma, flavor, acidity, body, etc., and provide an overall evaluation. Traditional cupping requires professional knowledge and experience to accurately assess each characteristic, making it more complex and specialized. The CATA method is more suited for rapid, large-scale consumer sensory testing, while traditional cupping forms are primarily used for professional coffee quality evaluation and trading.
CATA方法在CVA系統中的應用，增強了感官評估的科學性和可靠性，使得咖啡評估變得更加全面和精確。CATA簡單易用，無需專業訓練即可進行評估，適合大規模消費者測試。與傳統杯測表相比，CATA方法能夠快速收集大量數據，提供多層次的感官描述，幫助咖啡生產者和銷售者更好地理解和評估產品品質，滿足市場需求。CATA與CVA的結合，展示了其在專業評估和消費者研究中的巨大潛力。
The application of the CATA method in the CVA system enhances the scientific and reliable nature of sensory evaluation, making coffee assessment more comprehensive and accurate. CATA is easy to use, requires no professional training, and is suitable for large-scale consumer testing. Compared to traditional cupping forms, the CATA method can quickly collect large amounts of data, providing multi-layered sensory descriptions that help coffee producers and sellers better understand and evaluate product quality to meet market demands. The combination of CATA and CVA demonstrates its great potential in both professional evaluation and consumer research.
