What are Ready-to-Cook (RTC) Foods?

Ready-to-cook (RTC) foods are partially prepared food items that require minimal cooking or preparation before consumption. These products offer convenience to consumers by cutting down on preparation time, while still allowing them to enjoy freshly cooked meals. Common examples of RTC foods include marinated meats, instant noodles, pasta, pre-cut vegetables, and frozen meals. The production process for RTC foods begins with selecting high-quality raw ingredients, which are processed according to the type of product. For instance, vegetables might be washed, peeled, and cut, while meats could be marinated or seasoned. After processing, these foods are either packaged fresh or frozen to preserve their quality.

Producing RTC foods requires equipment such as portioning machines for precise sizing of ingredients, vacuum sealers or modified atmosphere packaging (MAP) systems to extend shelf life, and weighing and filling machines to ensure accurate portions. Sealing and packaging machines secure the RTC items in airtight, easy-to-open packages, while refrigeration systems maintain freshness throughout the production and distribution process.

Types of Ready-to-Cook Foods

RTC foods come in a wide range of categories, each requiring unique production processes. Below, we explore some of the most common types and the technical methods involved in their production.

Pre-Marinated Meats

Varieties:

  • Chicken Tikka: Boneless chicken marinated in a mix of yogurt, spices, and herbs, ready for grilling or baking.
  • Barbecue Pork: Pre-seasoned pork marinated in a smoky barbecue sauce.
  • Spicy Lamb Chops: Lamb chops marinated in a blend of chili, garlic, and herbs, ready for quick cooking.

Technical Processes:

  • Marination: Using tumblers or static mixers to ensure even coating and flavor penetration. Marination time is controlled to allow for flavor absorption without breaking down the meat structure.
  • Packaging: Vacuum-sealed or MAP (Modified Atmosphere Packaging) is used to extend shelf life and maintain freshness.
  • Freezing: For extended storage, meats are frozen at -18°C after packaging, preserving their quality and taste.

Instant Noodles

Varieties:

  • Ramen: Pre-cooked wheat noodles with flavor packets, ready for boiling or microwaving.
  • Rice Noodles: Gluten-free, quick-cooking noodles that can be boiled in minutes.
  • Vegetable Noodles: Noodles made from zucchini, sweet potatoes, or other vegetables, offer a healthier alternative.

Technical Processes:

  • Noodle Dough Preparation: Using high-speed mixers, dough is prepared and kneaded for uniform consistency.
  • Sheeting and Cutting: Dough is sheeted to a thickness of 1-2 mm and cut into desired shapes using precision cutters.
  • Steaming and Drying: Noodles are steamed at 90-100°C for 2-5 minutes, then air-dried or fried to reduce moisture content to around 8-12%.
  • Flavoring: Flavoring packets are created separately, including seasoning, dried vegetables, or sauces.
  • Packaging: Single-serve portions are packed in high-barrier materials to prevent moisture absorption and spoilage.

Frozen Meals

Varieties:

  • Pasta Dishes: Lasagna, macaroni, or spaghetti, partially cooked and frozen for quick reheating.
  • Casseroles: Ready-to-cook meat or vegetable-based casseroles, packaged for freezing.
  • Asian Stir-Fries: Pre-cut vegetables and marinated meats, ready for stir-frying.

Technical Processes:

  • Ingredient Preparation: Vegetables are washed, peeled, and cut, while meats are pre-cooked or marinated.
  • Assembly: Ingredients are combined and placed into trays or containers for freezing.
  • Freezing: Use blast freezers at -30°C to rapidly cool and freeze meals, maintaining texture and flavor.
  • Packaging: Vacuum sealing or MAP techniques are used to maintain product quality, prevent freezer burn, and extend shelf life.

Pre-Cut Vegetables

Varieties:

  • Stir-Fry Mix: A blend of pre-cut vegetables such as carrots, bell peppers, and onions, ready for quick cooking.
  • Salad Kits: Pre-washed and cut lettuce, tomatoes, cucumbers, and toppings, often including a dressing packet.
  • Vegetable Medleys: Pre-portioned mixes of root vegetables, ready for roasting or grilling.

Technical Processes:

  • Washing and Cleaning: Vegetables are thoroughly washed using automated systems to remove soil and contaminants.
  • Cutting and Slicing: High-speed precision cutters ensure uniform slicing, dicing, or julienning.
  • Packaging: Nitrogen flushing is often used in MAP to prevent oxidation and spoilage. Products are packaged in resealable, airtight containers for convenience.

Rice and Grains

Varieties:

  • Instant Rice: Pre-cooked rice that requires minimal preparation, such as boiling for 5-10 minutes.
  • Quinoa: Pre-washed and par-cooked quinoa, ready for quick preparation.
  • Mixed Grain Pilaf: A blend of par-cooked rice, barley, and lentils, seasoned and ready to be heated.

Technical Processes:

  • Pre-Cooking: Grains are boiled to 80-90% doneness to reduce cooking time for consumers. This is done in batch cookers under controlled conditions.
  • Drying: Grains are air-dried or dehydrated to reduce moisture content, extending shelf life.
  • Flavoring: Seasonings and oils are often added to enhance flavor and provide convenience.
  • Packaging: Vacuum-sealed pouches or MAP techniques are used to prevent moisture ingress and preserve freshness.

Engineering of Packaging Materials for Ready-to-Cook Foods

Packaging plays a critical role in maintaining the quality and shelf life of RTC foods. Different packaging technologies are employed based on the specific type of product and its shelf-life requirements.

Vacuum-Sealed Packaging

  • Objective: Extend shelf life and prevent contamination.
  • Materials: Multi-layer barrier films that prevent oxygen and moisture ingress.
  • Benefits: Maintains freshness by minimizing exposure to air, reducing the risk of bacterial growth.

Modified Atmosphere Packaging (MAP)

  • Objective: Preserve freshness and flavor for extended periods.
  • Materials: Packaging filled with a controlled atmosphere to reduce oxygen and prevent spoilage.
  • Benefits: Prolongs shelf life by inhibiting microbial growth and oxidation, especially in perishable items like pre-cut vegetables and marinated meats.

Sustainable Packaging Solutions

  • Objective: Reduce environmental impact and appeal to eco-conscious consumers.
  • Materials: Recyclable or biodegradable materials, such as paper-based trays or compostable films.
  • Benefits: Aligns with consumer demand for environmentally friendly packaging, while still maintaining product integrity.
