Formula calculation method: The impact of the proportion of fresh meat on the water content of the material

First of all, we need to know that the moisture requirement for dry food production materials is that the moisture content accounts for 20% of the total material, % People in their twenties are too many. The dog food coming out of the dryer cannot be directly cooled and bagged because the moisture content is still too high and needs to be dehydrated again... Basically, for the sake of efficiency and production speed, dog food factories will not find it for themselves. trouble.

Example: If 100 grams of production materials contain 50 grams or 80 grams of fresh meat, what is the moisture content?

Calculated based on chicken

50g*75%=37.5g; 37.5g÷100g=37.5%. The moisture content in the material has exceeded the 20% moisture content requirement for dog food production materials.

Based on duck meat

50g*80%=40g; 40g÷100g=40%. The moisture content in the material has exceeded the 20% moisture content requirement for dog food production materials.

Because our dog food meat is dehydrated first, for dog food with 50% fresh meat content, can the material enter the dog food production equipment (if the moisture is too high, the material will look like dough and will not enter. It is not clear that the dog food equipment must be dispersed and flowable when stirred). If it does not form agglomerates at this moisture content and can enter the machine, then the production may be possible, but the particles are prone to not forming and the moisture content exceeds the standard. , after passing through the dryer, a second dehydration process is required.

If at this moisture content, the material becomes dough-like and is not loose and flowable, then don’t worry about it. The machine will not be able to feed it, let alone production.

So, in general production, the proportion of fresh meat in mixed dog food with meat powder is 20-30%.

Example: If 100 grams of production materials contain 30 grams (30%) of fresh meat, what is the moisture content?

Based on chicken

30 grams * 75% = 22.5 grams, which is 22.5%, which is the upper limit

Based on duck meat

30g*80%-24g is 24%

Formula calculation method: How much real fresh meat is in a dog food

We often see the percentage of fresh meat labeled, and then vigorously promote "fresh meat food" Dog food~ The first impression is that this dog food has so much fresh meat, it must be very good!

But, is dozens of percent fresh meat really considered too much?

If there is really only 50% or 80% fresh meat content, no additional meat powder or purified protein powder (corn gluten meal, wheat protein powder/gluten powder, pea protein powder, etc.) or protein-rich raw materials will be added Ingredients (such as various beans, soybean meal, etc.)If so, the most basic protein cannot meet domestic dog food standards, let alone foreign dog food standards.

For example: If 100 grams of dog food contains 50 grams or 80 grams of fresh meat, what is the actual fresh meat content?

Based on chicken

50g*25%=12.5g; 12.5g÷100g=12.5% ​​actual fresh meat content

80g*25%=20g; 20g÷100g=20% actual fresh meat content

Calculated based on duck meat

50g*20%=10g; 10g÷100g=10% actual fresh meat content

80g*20%=16g; 16g÷100g=16% actual fresh meat content

Duck meat has a higher water content than chicken

So, if a dog food is advertised as containing dozens of percent fresh meat, you need to look through the formula list to see if there are meat meal, meat and bone meal, fish meal, various protein powders, and various kinds of high-quality meat in it. Protein ingredients.

How to calculate the real meat content in a dog food

In order to appear to have a high meat content, many dog ​​foods mix the proportion of fresh meat and the proportion of meat powder/dehydrated meat in the ingredient list. It does seem to have a high content...

But the reality is that dog food will be dehydrated during the processing process, and only after dehydration is the dry food you buy~The proportion of moisture in the fresh meat will actually be removed during the production process~

After removing the moisture, the true meat content of this dog food is revealed. We will not judge whether this approach is not "honest" enough, because for the purpose of publicity and sales, this approach is normal. If it were us, we might also use this approach~

Example:100 grams of dry dog ​​food advertises 50% fresh meat. We do not consider the problems faced in its production process and only calculate the meat content.

Contains 30% fresh meat A, 20% fresh meat B, and 15% meat powder C

Then, the real meat content is:

Fresh meat A is chicken, 30g*25%=7.5g

Fresh meat B is duck meat, 20g*20%=4g

Meat powder C is already in a dry state, 15 grams = 15 grams

Therefore, the surface content of this dog food is 50% fresh meat and 65% meat content, but the actual meat content is 26.5%. This meat content is not low in dog food on the market.
