Key Points:

Enzymes in Dog Food: Protease (breaks down proteins), Lipase (fats), Amylase (starches).
Freeze-Drying Process: Low temperatures and vacuum remove moisture without heat damage.
Health Benefits: Better digestion, energy, and overall vitality.
Storage & Preparation: Store in a cool, dry place; rehydrate before serving.

Switching to freeze-dried food can boost your dog's nutrition and health while maintaining the convenience of long-term storage.

Enzymes in Dog Nutrition

Basic Enzyme Functions

Enzymes are proteins that act as biological catalysts, breaking down complex food molecules into simpler forms for easier digestion. These proteins work throughout your dog's digestive system, starting in the mouth and continuing until food is fully processed in the intestines.

Main Enzymes in Dog Food

There are three key digestive enzymes that play a role in your dog's nutrition:

Enzyme Type	Function	Targets
Protease	Breaks down proteins	Found in meat, eggs, fish
Lipase	Processes fats	Found in oils, animal fats
Amylase	Breaks down starches	Found in carbohydrates, vegetables

Protease converts proteins into amino acids, which help with muscle repair and growth. Lipase transforms fats into fatty acids, providing energy and supporting cell health.

How Enzymes Help Dogs

Enzymes improve nutrient absorption, simplify digestion, and help maintain energy levels by breaking food down efficiently. This becomes even more important as dogs get older and their natural enzyme production slows down. Freeze-drying helps preserve these enzymes, ensuring your dog gets the nutrients they need for optimal health.

How Freeze-Drying Works

Freeze-Drying Basics

Freeze-drying, or lyophilization, is a preservation method that removes moisture from dog food using low temperatures and a vacuum. Unlike standard dehydration, it skips the liquid phase entirely, turning frozen water directly into vapor through sublimation.

This process keeps the food's cellular structure intact while preserving its nutrients and enzymes. As the water freezes, tiny ice crystals form channels that allow moisture to escape, leaving the food's natural composition undisturbed.

These principles form the foundation for the steps involved in freeze-drying.

4 Main Freeze-Drying Steps

Pre-FreezingIngredients are frozen to temperatures below –40°F (–40°C). Rapid freezing creates smaller ice crystals, which helps maintain the structure of the food and its enzyme activity.
Primary DryingThe frozen food is placed in a vacuum chamber. Under reduced pressure, the ice sublimates directly into vapor, removing most of the water while preserving nutrients and flavor.
Secondary DryingThe temperature is gradually raised in the vacuum to eliminate any remaining moisture. This step ensures the food is thoroughly dried without affecting its preserved enzymes.
Final PackagingThe dried food is sealed in moisture-proof packaging to prevent rehydration and keep its nutritional quality intact.

Freeze-Drying vs. Other Methods

Freeze-drying stands out because it avoids the high heat used in other drying methods, which can damage enzymes and nutrients. The controlled vacuum environment also minimizes oxidation, helping to retain the food's natural qualities and enzyme activity.

Enzyme Protection Through Freeze-Drying

Let’s take a closer look at how freeze-drying helps maintain enzyme activity in dog food.

How Temperature Affects Enzymes

Freeze-drying uses controlled low temperatures to safeguard enzymes during processing. By freezing quickly and carefully removing moisture, it prevents heat damage that could deactivate the enzymes. Once rehydrated, these enzymes are ready to aid digestion, helping your dog absorb nutrients more effectively.

Preserving Enzyme Activity

This method keeps enzymes functional during storage and rehydration. It ensures they retain their ability to break down proteins, fats, and carbohydrates, so your dog gets the full nutritional benefits.

Loyal Saints’ freeze-dried products align with AAFCO standards while keeping the enzymes from raw ingredients intact. When rehydrated, these enzymes go back to work, promoting better digestion and nutrient absorption.

Health Benefits of Enzyme‐Rich Dog Food

Freeze-drying doesn't just preserve enzymes - it also brings a range of health perks for your dog.

Improved Digestion

Active enzymes help break down nutrients more effectively, aiding digestion and ensuring your dog absorbs nutrients better.

"We prioritize thoughtful formulations that not only nourish your pet but also enhance their vitality and happiness. By focusing on optimal nutrition, we help ensure that every pet thrives, enjoying an active and flourishing life." – Loyal Saints Pets

This is particularly helpful for dogs with sensitive digestive systems.

Support for Sensitive Stomachs

Dogs with delicate stomachs or dietary challenges often experience noticeable benefits after switching to enzyme‐rich freeze-dried food. These natural enzymes reduce digestive strain and improve food tolerance, making mealtime easier for pets prone to stomach issues.

Overall Health Benefits

Enzyme‐rich food contributes to better energy, stronger muscles, and overall vitality. The preserved enzymes improve protein absorption, which supports muscle growth and keeps your dog more energetic.

As pet owner Tony Eiguesse puts it: "I'd rather spend $200 a month on my picky eater and have them happy for years than a couple thousand on vet bills. This food rocks!"

Selecting and Using Freeze-Dried Dog Food

What to Look for in Quality

When picking freeze-dried dog food, focus on options made with whole, natural ingredients and high-quality proteins. Check the packaging to ensure it uses human-grade ingredients and complies with AAFCO nutritional standards.

Avoid products with artificial preservatives or fillers, as these can interfere with the food's nutritional integrity. Look for recipes that include nutrient-rich fruits and vegetables to provide a balanced diet for your dog.

How to Store and Prepare It

To keep the food fresh and maintain its nutritional benefits, store it in its original resealable packaging. Keep it in a cool, dry, and dark place.

When you're ready to prepare it, follow these steps:

Measure the correct portion based on your dog's weight.
Add warm water, mix well, and let it sit for 3–5 minutes to fully rehydrate.
Make sure the food is completely rehydrated before serving.

Transitioning to Freeze-Dried Food

Switching to freeze-dried food should be done gradually to avoid upsetting your dog's stomach. Here's a suggested schedule to ease the transition:

Days	Current Food	Freeze-Dried Food
1–3	75%	25%
4–6	50%	50%
7–8	25%	75%
9–10	0%	100%

Keep an eye on how your dog adjusts during the transition. Notice any changes in digestion or excitement at mealtime. If your dog shows signs of digestive discomfort, slow down the transition by extending each phase a few more days.

Conclusion

Freeze-drying works by carefully removing moisture while maintaining controlled temperatures, which helps preserve enzymes crucial for your dog's nutrition and overall health.

Pet owners have noticed benefits like improved digestion, healthier coats, and relief from stomach issues when switching to freeze-dried food. This method not only keeps essential enzymes intact but also ensures the food retains its nutritional quality over time.
