Lyka: Redefining Pet Food

NUTRITION


When choosing what type of pet food is the best to feed your four-legged friend, there are a number of factors that should guide your decision. The amount of processing is one of them.

When we humans make our daily food choices, we try and stay away from ultra-processed and packaged foods. We’ve heard from doctors that nourishing our bodies with fresh foods is the best thing for our health. This same logic can be transferred to our pets.

What exactly is food processing? It is mechanical or chemical operations on food in order to change or preserve it.1 Heat processing and chemical additives are common processing methods in pet food.

Why is processing good? Processing kills bacteria and pathogens in the food, decreasing risks of food-borne illnesses.

Why is processing bad? Processing kills natural nutrients, which then need to be added back with artificial ingredients. For example, food that is labelled primarily “beef”, but has been highly processed, might have a lower quantity of nutrients coming from the beef itself, then you think.

A range of processing methods are used for pet food, from highly processed dry foods to unprocessed raw foods. Each method has their positives and negatives, and the key is to balance these. The balance of minimizing foodborne risks, while maximizing natural nutrient retention is something that’s important to us at Lyka Pet Food.


Here’s a low down on the common pet food processing methods.

Dry Food

Processing Method

Dry food undergoes a process called extrusion. The food is cooked at a very high heat, between 100 and 200 degrees Celsius, and then dried by re-heating it again, to up to 100 degrees Celsius. After this, it is typically sprayed with flavour enhancers and/ or preservatives.2

Pros

  • Dry food can be stored outside of the fridge, making it convenient to buy and use
  • Because the food is in a kibble shape, the feeding process is “mess free”

Cons

  • Natural vitamins and minerals are lost during the heating process, so typically artificial ones added in their place
  • Because of the high heat processing, the moisture levels of the food are very low, which may make it harder for pets to stay hydrated
  • The food is not fresh: usually, dry foods are shelf stable for many (many!) years.

 

Canned Food

Processing Method

Ingredients are typically cooked at lower temperatures than dry food and then filled into cans. Additives are used to keep the food shelf stable. Finally, cans must be heat sterilized to control harmful bacteria that may grow while they are distributed and stored. This is done by heating the cans to a minimum of 116 degrees Celsius. 3

Pros

  • Canned food can be stored outside of the fridge, making it convenient to buy and use
  • They have higher moisture levels than dry foods, helping pets stay hydrated

Cons

  • As with dry food, natural vitamins and minerals are lost during the heating process, so typically artificial ones added in their place
  • The food is not fresh: usually canned foods are shelf stable for years, although typically less than dry foods.

 

Chilled Food

Processing Method

There are many different types of chilled foods such as mince, loafs, rolls and chunks, and the processing methods vary between them. In general, they are less processed than canned foods, as they don’t need to go under heat sterilization. However because they are manufactured to withstand long expiry dates, they usually contain artificial preservatives.

Pros

  • They have higher moisture levels than dry foods, helping pets stay hydrated

Cons

  • Natural vitamins and minerals are lost throughout time in storage, so typically artificial ones added in their place
  • The food is not fresh: usually chilled foods are shelf stable for anywhere between months and years.

 

Raw Food

Processing Method

Raw foods undergo minimal processing: the ingredients are cut, mixed together and refrigerated or frozen, ready for consumption.

Pros

  • Natural nutrients are retained given the food goes under minimal processing
  • They have higher moisture levels than dry foods, helping pets stay hydrated

Cons

  • The risk of pathogen contamination (such as e Coli and Salmonella) increases significantly compared to other foods, as no processing methods are used to kill bacteria. The risks concern both pets eating the food, and owners handling the food.4
  • Not all dogs can handle eating raw food, and some may get sick after it
  • Some types of raw food, may not be specifically balanced to contain all the nutrients needed for pets to thrive

 

Lyka Pet Food

Processing Method

Lyka is a mixture of raw ingredients, as well as ones that are gently cooked  under low heat, to retain maximum nutrients and at the same time kill harmful pathogens. Prepared on order, so your dog will be eating it just days after it has been made.

Pros

  • Natural nutrients are retained due to under minimal processing level
  • The food is freshly made days before delivery without the need for artificial preservatives
  • Safe from pathogen contamination, as bacteria are killed during the light cooking

Cons

  • Your dog might not want to eat anything else!
