Fructooligosaccharides in Dog Food

As a prebiotic fructooligosaccharides (FOS) is used for pet animal’s food which mainly enhances the digestibility of your pet. By the definition of FOS, it is non-digestible and extracted from the sugarcane by fermentation process. Theoretically it contains 2 to 60 monomers and commercial fructooligosaccharides (FOS) is produced from inulin by hydrolysis process, which is also an oligosaccharide. Chemically FOS is a mixture of the following components:

Inulin usually found in chicory root and highly soluble into hot water. Human and dog’s digestibility are not same. Usually dogs don’t digest effectively the grains and vegetables as man can do. FOS is added for enhancing the digestibility of dogs. But excessive addition FOS to your dog’s food may cause flatulence and bloating. On the other hand, Inulin is not much deteriorating as it doesn’t increase triglycerides in blood.

Fructooligosaccharides in Dog Food- is it safe?

Before understanding this, you must need proper knowledge on Prebiotic, Probiotics, Synbiotic and Postbiotic which are most common terms uttered when the word Fructooligosaccharides (FOS) comes.


Prebiotics vs Probiotics

Although probiotics are a completely different category than prebiotics, the two create a symbiotic effect when use in conjunction with each other. The end result being better digestive health. Recent studies have shown that of the two, prebiotics seem to have a more substantial health benefit.


Probiotic is a kind of supplement that is consisted of sufficient number of microorganisms which is beneficial to health. Micro-organisms, typically Lactobacillus, Bifidobacterium, Streptococcus are these types of members. These bacteria are fermentive, obligatory, or facultative, anaerobic organisms and they produce lactic acid.


Around the decade of 90, “Prebiotic” word is familiar with the world. From this it can be assumed easily that it is not so many long times when the science is dealing with the digestive system of human body as well as other pet animals. According to Biology, the most complicated system of human body and animal is brain. if anyone wants to rank the complexity, I’m pretty much sure he’ll give the digestive system in second position. In Biology these two terms are complex most than others. To know the unknown is the passion of researchers and that’s why more researches are done on these two complex systems.

Prebiotics are Indigestible

By definition, prebiotics are those kinds of fibers or supplements whose enhance the digestibility of stomach. It can be taken from different kinds of foods which are consumed by human and animals daily. But the problem is, they are found on those foods in a very small quantity which are inadequate for the body nourishment. Among these foods the different kinds of grains are the biggest source of prebiotics. When grains are consumed in daily basis, the growth of prebiotic Microorganisms get sufficient nourishment so as your pet digestive power improves. Lacking of this kinds of food may increase the growth of pathogenic microorganisms which results an unhealthy digestive system of your pet. So, your pet becomes unhealthy and looks pale.

By definition, prebiotics are non-digestible food ingredients which give nutrition to probiotic microorganisms. Usually prebiotics are indigestible by humans as well as animals. Oligosaccharides are these types. Presence of this prebiotics selectively promotes the prolife ration of certain microorganism which usually lives in colon area. Oligosaccharides contains fructose chains and glucose. Examples fructo-oligosaccharides (FOSs), (which is produced from the raw sugar cane fermentation process) Inulin etc.

Inulin is an all-natural dietary organic prebiotic fiber, also known as a fructan.  Most plants contain varying amounts of inulin, with the Agave plant and Chicory root being the most commercially viable. The majority of inulin being used today is from chicory root, which contains about 15% inulin while agave plants contain up to 38% inulin. Source of organic agave inulin is extracted from the Agave plant. The end result of the inulin refining process, yields a fine, highly soluble powder, with a neutral, clean, and mildly sweet flavor.

There are various types of inulin, some inulin is very soluble in cold water. They have more calcium and minerals than other inulin. Inulin is also a prebiotic. Prebiotic fibers are food ingredients, that because of their molecular makeup, are able to enter the lower digestive tract basically intact. Studies have shown, as the prebiotic (inulin) ferments in the colon beneficially feeds the good bacteria and enhances the digestibility of host.


Improving digestive health is one of the most important applications of inulin for commercial use. Helps low-fat dairy versions of products such as yogurt, ice cream and milk beverages, to have an improved taste and texture, while adding the health benefits associated with prebiotic fiber ingredients. Important Other Categories of Inulin Uses:


N.A. (Non-Alcohol beverages) i.e. juices, teas, flavored waters, sports drinks etc. The addition of prebiotic fiber, currently used extensively in all categories of food and beverages throughout Europe and Asia, is forecast to be one of the most used functional additives in the U.S. Beverage Industry for the next 5 to 10 years. The increased solubility and other favorable attributes of Agave Inulin compared to the currently used alternatives and the increase in public awareness towards the benefits of digestive health in general, makes the forecast for the usage of Organic Agave Inulin in NA products, exciting and healthful.

Nutritional Supplements

Pet Foods

Inulin is also beneficial when added to pet food products as it helps in, stimulating the gut integrity, nitrogen metabolism, and even reduces fecal odors. FOS is mainly consisting of inulin which has been using worldwide for many years.

current inulin market trends for the U.S:

With the current prebiotic fiber U.S. market standing at around $110 million, Market research firm Frost & Sullivan reports that around 35% of the market share entails the use of inulin.

UBIC Consulting’s 2010 report notes that, since 1999, the market grew more than 120% from 1999-2010, according to the “The World Prebiotic Ingredient Market.”

Global Industry Analysts Inc. (GIA) reports that the U.S. market for prebiotic fiber will double reaching $225.1 million by 2015. The GIA’s “U.S. Report on Prebiotics” finds the U.S. the largest product segment in the U.S. prebiotic market.”


Synbiotic is a combine product of these two biotics.


A metabolic byproduct which is generated by  probiotic microorganisms.It usually stimulates the digestive system of the carrying host.

Functional food

Functional food is defined as modified food that contains other benificial microorganisms in association with its selective purposeful microorganisms. For example, yogurt.

Nutritional Needs for Different Dog-types

Whatever the purpose or nature of the job, the performance of work always requires time expenditure of energy. They seldom are required to expend energy in excess of normal activity for any duration of time.

Some facts you should know about your dog

  • Dogs should have regular elimination times. This will establish a regular pattern. Such a pattern promotes regular eliminations, stimulates better digestion, and increases food utilization.
  • Most of the true nutritional diseases are deficiency diseases. These will most likely show on the pads of the feet, between the toes and over the bony protuberances of the body where pressure reduces the blood supply. It may also produce anemia, reduce the body’s ability to cope with and recover from infections, and, if left neglected, will eventually lead to the dog’s death.
  • Protein Deficiency in Dogs
  • Most of the eatable vegetables for dogs are practically all water. What roughage they may contain can just as easily be obtained from cereal grains. Cereal grains are one of the major sources of carbohydrates, both for dogs and man, is the cereal grains. The useful carbohydrate in these grains is predominantly starch. Starch can also be purchased in pure form, and contains about 29 calories per tablespoon, or about 464 calories per cup. Other sources of carbohydrate energy from cereal grains can be obtained from dry and cooked breakfast cereals, boiled rice, hominy grits, corn meal, and in the milled form, such as flour. Potatoes can be used interchangeably with those cereals that are fed in the boiled state. But you must calculate the exact amount of grains to add that will provide an adequate supply of vitamins.

Mineral Sources

In natural diets, most of the trace minerals are found in adequate amounts in the natural ingredients

Bone meal

It should never be added in excess of 1/2 ounce per pound of the total diet.

Playing with your dogs

Ordinarily this is for extended periods of time. Such sustained performance requires huge amounts of energy. At the same time, it must contain all of the necessary nutrients that are balanced to the increased caloric density. What’s more, when the digestibility of the proteins and carbohydrates is improved, the odor of the small quantity of stool that is produced will be considerably less.

Energy Sources

Meat is also the most common protein source as described previously. These are the foods containing the largest quantities of fats and carbohydrates. Carbohydrates, while not as concentrated an energy source as fats, are lower in cost. There are many brands in market which gives us the ready-made meat.

These brands have all been reformulated and are much improved. They don’t add them, but the preservatives have already been added to the raw ingredients before being purchased by the company as the Preservatives are necessary in all pet food.



It usually is fortified with vitamins and minerals, is palatable to most dogs, and is always available and inexpensive. While such a practice makes the slices easier to crumble and mix with the rest of the diet, the starches in bread have already been subjected to cooking and about all toasting does is to enhance the texture of the bread.



From all these discussions, we can summarize that fructooligosaccharides (FOS) which is mainly consists of inulin, is a prebiotic and indigestible food ingredient. It mainly enhances the digestibility of your dogs as well as pet. Proper using of this prebiotic will make your dog healthy. From many experiment it is found that 0.095% FOS using with dog’s food PH is below than 0.05. And it occurs because the production of lactate becomes more than previous. Although FOS is beneficial to dog’s health, flatulence and bloating may occur if you overfeed your dog which is an effect of excessive lactic acid presence. So, experts recommend that one-half is enough dose for your dog until your dog cope up with it.
