Digitizing a Chinese Cookbook: Yinshanzhengyao 飲膳正要

Introduction

Food is an integral part of Chinese culture. Many things in Chinese culture revolve around food. Different occasions are associated with different cuisines, and different parts of China have developed over time their own distinctive cuisines.

Yinshanzhengyao (飲膳正要), a culinary manuscript published in 1330 during the Yuan dynasty, remains a significant historical document with all existing editions tracing their roots back to the Ming dynasty edition of 1456. Remarkably, it stands as one of the oldest extant dietary manuscripts, providing a fascinating glimpse into the culinary practices of ancient China. The detailed records contained within its pages offer a unique window into the daily lives and gastronomic preferences of individuals during the Yuan dynasty.

What sets Yinshanzhengyao apart is its incorporation of traditional Chinese beliefs linking specific ingredients and foods to distinct attributes. This aspect adds an intriguing layer to the manuscript, as it underscores the cultural significance of food beyond mere sustenance. In Chinese culture, the consumption of particular foods is believed to have therapeutic benefits, aiding in the treatment of specific ailments or promoting longevity. This perspective on the interplay between diet and well-being is a distinctive feature not commonly found in Western culinary traditions.

Therefore, we would like to digitize this cookbook in this project making it more accessible to more people around the world.

For this project, there are two objectives:

• Perform data analysis for the recipes in the cookbook which would hopefully help us better understand how Chinese cuisines evolved over time and quantify the relationship between ingredients and medical effects
• Develop a dedicated webpage which display recipes from the cookbook and users of the website can browse these recipes and search recipes with selected ingredients and medical effects

Deliverables

1. Digitized recipes from the cookbook: One csv file containing recipe name, ingredients and cooking steps in Chinese and English
2. Categorized ingredients, effects, cooking methods, and cuisine categories: One csv file for each category
3. Website: One webpage displaying recipe entries and figures of data analysis with search functionality
4. Wiki: One wiki page providing an introduction and comprehensive description of the entire project
5. Github: One Github repository to showcase all codes and technical aspects of the project

Methods

Data Collection

Figure 1. Chinese Text project website pages for book "Yinshanzhengyao"

"Yinshanzhengyao" was published in 1330 during the Yuan dynasty, and all existing editions are derived from the Ming dynasty edition of 1456. Despite the presence of a scanned version of the book on the internet, Optical Character Recognition (OCR) poses a challenge due to the ancient Chinese text and the inclusion of illustrations. Fortunately, the Chinese Text Project (中國哲學書電子書計劃) has undertaken the noble initiative of providing open access to ancient Chinese books for both Chinese and non-Chinese scholars, resulting in the creation of a comprehensive database. Currently, it encompasses over thirty thousand books, making it the largest among historical Chinese literature databases.

"Yinshanzhengyao" is among the books included in this extensive database. Leveraging the well-defined structure of the database, we scrape data from the website. Given the project's specific focus on the recipes within the book, our data extraction is limited to the recipe content, which includes the following chapter:

• Strange Delicacies of Combined Flavours 1, 2, 3
• Various Hot Beverages and Concentrates
• Foods that Cure Various Illnesses

In total, there are 210 recipes, each accompanied by information on its effects, ingredients with quantities, and step-by-step instructions. As a medical text, the "effect" refers to the benefits of the food and precautions to be taken, providing valuable insights into the medicinal properties of the recipes.

Data Processing

Construct dataset

Upon acquiring data from the website, the imperative task is to clean and structure the data into the following format: Food_Name, Effect, Ingredients, Steps. However, due to the website not well separating these four pieces of information, we developed functions to customarily construct this dataframe. Below are examples of recipe dataframes.

Translation: Ancient Chinese to Modern Chinese

Figure 2. Ancient Chinese to Modern Chinese model

The text is originally in ancient Chinese, but contemporary communication predominantly uses modern Chinese. Therefore, for thorough data analysis, it is crucial to translate the recipes from ancient Chinese to modern Chinese. In our assessment, we compared the proficiency of a translation model for ancient Chinese to modern Chinese (Figure 2) against ChatGPT 3.5. Our findings indicate that the translations generated by ChatGPT are more fluent and closely aligned with contemporary language usage. Based on this observation, we have opted to use ChatGPT as our primary translation tool. Furthermore, since translating the Food Name and Ingredients would be meaningless, the translation will only be implemented for the Effect and Steps. Here are some examples of the translation:

English Translation

Figure 3. A Soup for the Qan: Chinese Dietary Medicine of the Mongol Era As Seen in Hu Sihui's Yinshan Zhengyao

In the process of English translation, we discovered a digital document online containing the English version of the book (Figure 3) . As a result, we extracted the English-translated recipes from this document and established an English database for the recipes. Following this, we compiled a comprehensive recipe dataset that incorporates both English and Chinese versions. For the categorization of English data, leveraging the pre-existing categorized data in Chinese, we developed a mapping method to establish a correspondence between Chinese and English categories. All tables above, containing English content, are the outcome of mapping to the Chinese dataframe generated earlier.

Data Analysis

1. Recipe

According to the pie chart “distribution of recipe category” to observe the overall distribution of different kinds of recipes in the cookbook and have a general understanding of the recipes. This cookbook contains all kinds of foods, staples like noodles, rice noodles and steamed buns, dishes, desserts, and drinks such as tea and pulp. It is found that main dishs (34.3%), soups (25.2%) and congees (9.1%) make up the majority of the recipes.

Figure 4. Recipe Categories Distribution

2. Ingredient

Firstly, we made a word cloud to show the overall frequency of all ingredients. One notable finding involves the examination of ingredient frequency, where "Mutton" emerged as the most frequently occurring ingredient. This observation aligns with the historical context of the book, which was written and published during the Yuan dynasty, known for its Mongol leadership and renowned for mutton dishes. Tsaoko is the second most frequent ingredient, and from the analysis of ingredient pairing we found that the combination of "Mutton" and "Tsaoko cardamom" occurs most frequently, considering that Tsaoko cardamom can help mitigate the smell of mutton, so they are the perfect pairing in this cookbook. In addition, tsaoko cardamom is an important spice for many dishes, it co-occurs quite often with lamb, prepared tangerine orange peel, chickpeas, galangal and many other ingredients. And many frequent ingredients like prepared mandarin orange peel, lesser galangal, and liquorice are important Chinese medical materials.

Figure 5. Ingredient Word Cloud

Figure 6. Ingredient Pairing Heatmap (frequency)

Furthermore, the analysis of ingredient categories revealed that "meat" is the most frequently occurring category, closely followed by Chinese medicinal materials, which aligns with the dual character of the book as both a culinary and medical text.

Figure 7. Ingredient Categories Distribution

By counting the frequency of co-occurrence of various ingredient categories and normalizing by rows, we get a heatmap to observe the pairing of ingredient categories. It can be found that meat and spice is the most frequent pairing, also the co-occurrence frequency of meat, spice, plant and Chinese medical materials is high, and Chinese medical materials and many kinds of ingredients can be paired for cooking.

Figure 8. Ingredients Co-occurrence Heatmap

3. Cooking method

The most frequent cooking methods are simmer and boil, and the reason for this would be that approximately one-third of the recipes are soups and congees, which need to be simmered or boiled. Moreover, many Chinese medical materials need to be simmered for a long time in order for them to be effective.

Figure 9. Cooking Methods

4. Effect

According to the distribution of effect category, the most frequent one is general health and wellness, and there are also many recipes that can help alleviate or cure specific ailments, such as gastrointestinal issues, musculoskeletal issues, neurological and mental health, and so on.

Figure 10. Effect Categories Distribution

According to the correlation analysis between ingredients and effects, it can be found that most ingredients are related to general health and wellness. And some ingredients have certain specific effects, for example, sheep’s fat is good for musculoskeletal issues, Chinese radish, liquorice, and prepared mandarin orange peel are helpful in improving the gastrointestinal system.

Website

Figure 13. Front page screenshot

Figure 14. Recipe recommendations

For the website, it can be divided into two main components. One is the recipe search functionality, and the other is the visualization of data analysis. We developed these two parts independently and then combined the two into a Google Sites webpage, including additional information of the cookbook. Our website can be found in Digital Chinese Cookbook Website, and the front page of the website is shown in Figure 13 In this section, we will discuss these two components in more details.

Figure 15. Recipe table

Figure 16. Final design for the search functionality

Recipe Search

To allow user to search through the collection of recipes in the cookbook, we first construct a webpage that displays all the recipes in a HTML table with cooking method, ingredients used, and the effects associated with each entry, and the result is shown in Figure 12. Specifically, we generate a JSON file containing all the recipes, including the recipe name, the category of the dish, an array of ingredients used, an array of effects associated, cooking steps, the cooking method, and an array of effect categories. With the JSON file, we populate entries of the table dynamically when the page is loaded by templating pre-defined HTML tags in JavaScript. As for the search functionality, we include a search bar where the user can type in search text and checkboxes for ingredients, effects, etc. to filter recipes. Specifically, we incorporate a fuzzy search library, Fuse.js, which is capable of doing fuzzy match with user inputs, and we re-populate table entries with the search result. The final result is shown in Figure 13. The search bar is at the top and there are four checkbox groups in the middle. After inputting search criteria, the user can click cook button and the search result will be shown in the bottom of the page.

Figure 17. Interactive diagram showing recipe category distribution

Analysis Visualization

For visualization, we use Apache ECharts to create interactive diagrams of the data analysis result. One of the diagrams is shown in Figure 14, where the user can see the number of recipes in each category when hovering over it.

On top of these, we also include a selection of recommended recipes on the website and is shown in Figure 14.

Limitations

Data processing:

• Some of the data in the recipes were not fully utilized in the data analysis, such as the amount of ingredients.
• Some of the steps in the data processing were handled manually without a proper processing model, which makes it difficult to apply to other large datasets.
• Only some broad categories were defined about the efficacy of the dishes, which could be connected with Chinese medicine for more specific categorization and interesting analysis.
• There are some problems in translating ancient Chinese into modern Chinese or English, and it may be difficult to realize an English translation of all the content without an English version of this cookbook.

Website Construction:

• Not all of the recipes searched for in the website can be implemented, and some of the recipes may be difficult to reproduce now due to the difficulty of obtaining some Chinese herbs, or the fact that some unique cooking methods are not applicable to modern cooking tools.
• The website could be further improved, e.g. by linking some parts of the interactive charts to the corresponding detailed information.

Outlook

• There could be more interesting angles of data analysis, but they are difficult to realize. For example, historical analysis of recipes, exploring which recipes or ingredients are lost, is difficult to accurately verify due to limited knowledge of the subject and the fact that many of the herbs themselves are very uncommon.
• There are other chapters in the cookbook that cover various ingredients and their properties and efficacy, so in the future the recipes can be analyzed in more depth by combining other data from the book.
• Make further improvements to the content and functionality of the website. Link sections in the visualization charts to the corresponding recipe details; improve the search function, e.g. by displaying the corresponding number of recipes in the options bar.
• If the website can be widely used, a community could be created where users can exchange experiences of cooking according to recipes, or improving ancient recipes with present-day ingredients, as well as different insights into recipes based on different cultural contexts.

Broader research in the cultural field

• It would be interesting to learn more about the origins and development of the recipe, analyze the eating habits of the people at that time, and use this to explore the customs of the people's lives in the context of more of the recipe's historical, regional, and other cultural backgrounds.
• If possible, collect more information about the recipes and compare them with recipes from different dynasties, different regions of China, or even different countries during the same period.
• Connect with Chinese medicine and Chinese culture to trace the development of ancient Chinese medicine and explore the mysterious Chinese culture.
