From Supplier to Kitchen: PIE Students Explore the Food Supply Chain at LSH Cambodia

For a professional chef, understanding food begins long before an ingredient reaches the kitchen.

On August 31, PIE’s Basic students, accompanied by PIE chefs, took part in a field trip to the warehouse of LSH (Cambodia) PTE LTD, one of Cambodia’s established food importers and distributors. The visit provided students with an opportunity to step outside the training kitchen and discover what happens before products arrive at a restaurant, hotel, or professional kitchen.

Understanding Where Food Comes From

In culinary education, students spend much of their time learning how to select, prepare and present ingredients. But professional kitchens also depend on a well-organized supply chain.

During the visit, students were introduced to the role of a food-service distributor and gained a better understanding of how products move from suppliers to professional kitchens and hospitality businesses.

LSH works with international partners across numerous countries and supplies a wide range of products, including meat, dairy, bakery products, confectionery, beverages and other food-service items. Its distribution network serves restaurants, hotels and resorts, caterers, retailers, schools and other institutions.

For future chefs, this knowledge is important. Knowing where ingredients come from, how they are transported and how they are stored can directly influence food quality, menu planning and ultimately the guest experience.

From Delivery to Storage: Why Food Safety Matters

One of the key lessons of the visit was that food safety does not begin when a chef starts cooking. It begins much earlier, during purchasing, receiving, transportation and storage.

Students were able to see how different categories of products require different storage conditions. Chilled products, for example, must be maintained within controlled temperatures, while frozen products require significantly lower temperatures to preserve quality and safety.

LSH’s warehouse operations include dedicated dry, chilled and frozen storage areas, with chilled storage maintained at approximately 1–4°C and frozen storage at -18 to -25°C. The company also holds HACCP certification for its Phnom Penh facility, reflecting the importance of systematic food-safety controls throughout its operations.

For culinary students, these principles are essential professional knowledge. Poor temperature control, incorrect storage or improper handling can compromise food quality and increase the risk of foodborne illness.

FIFO: A Simple Rule with a Big Impact

Another important principle students encounter in professional food operations is FIFO – First In, First Out.

The concept is simple: products that arrive first should generally be used first, provided they remain within their required shelf life and quality specifications.

Correct stock rotation helps kitchens reduce food waste, avoid unnecessary financial losses and prevent products from being forgotten at the back of a storage area until they expire.

Professional purchasing and inventory management also involve checking quantities, product specifications, expiry dates, storage requirements and the condition of goods when they are received.

These may seem like small operational details, but together they contribute to a kitchen that is safer, more efficient and more financially sustainable.

Connecting the Warehouse to the Professional Kitchen

The field trip helped students connect concepts learned in the classroom and training kitchen with the wider hospitality industry.

A chef needs to understand ingredients not only from a culinary perspective, but also from an operational one. Purchasing decisions influence the food cost. Storage conditions affect quality. Stock rotation affects waste. Delivery schedules influence menu planning. And food safety procedures protect both guests and the reputation of a business.

This broader understanding is particularly valuable as students begin preparing for professional kitchens, hotels, restaurants and their future internships.

Learning Beyond the Kitchen

At PIE, practical education is not limited to cooking techniques. Understanding the hospitality industry means looking at the complete journey of food – from supplier and purchasing, through transportation and storage, to preparation, service and ultimately the guest’s plate.

The visit to LSH gave students a closer look at this often unseen part of the hospitality and culinary industry and highlighted the many professionals who contribute to a successful food operation.

For future chefs, knowing how to cook is only one part of becoming a professional. Understanding the ingredients, systems, people and processes behind the kitchen is what helps turn culinary skills into professional expertise.
