Why Homemade Baby Formula Recipes Simply Are Not Safe

Do Babies Really Die?


Scour the internet and there are countless blogs and websites dedicated to telling you about ‘toxins’ in the body, foods and most notably, baby formula. While some see breastfeeding as the only way to nourish a baby, and anyone who disagrees are terrible parents. There are some people who just take it the extra step, and think they can recreate a baby formula with their Vitamix and dreams.

Yet, if those same parents stopped and googled ‘Is Homemade formula safe?’, they’d get an entirely different picture. We don’t think anyone is intentionally wanting to harm their baby by making their own formula, but they certainly aren’t taking into account the years of research, tests, and nutrients that are carefully balanced in every formula. Something that needs to be created in a lab, not your back kitchen.

How Is Formula Made?

Raw Materials


As described on Made How, protein used in formulas can come from a variety of sources such animal milk or soybeans. Soy milk is made by taking soybeans, soaking them in baking soda, draining them, grinding the beans, then diluting the mixture with water and homogenizing it. The proteins, which come from soybeans, may be in the form of protein concentrates or protein isolates. The latter helps eliminate or reduce carbohydrates that can cause flatulence and abnormal stools. Other useful proteins can be derived from nuts, fish, and cottonseed oil but these have limited application in infant formulas.

Fats and carbohydrates

Fats and oils are an important dietary requirement for infants. Therefore formulations attempt to match the serum fatty acid profile of real breast milk. These fatty acids include eicosapentaenoic acid (EPA) which may be derived from fish oil and other sources. In actual breast milk there is a significant amount of fatty compounds known as triglycerides. For example, docosahexaenoic acid (DHA) is believed to be an important triglycerides. Triglycerides which are similar to (but not biochemically identical to) those found in breast milk can be derived from egg yolk phospholipids. Alternatively, fatty acid precursors (molecules which react to form dietary fatty acids) may be added to infant formula. These precursors (e.g., alpha and gamma linolenic acid) allow the infants’ bodies to synthesize the necessary fatty acids. However, this method is not as efficient for delivering fatty acids as breast milk is.


The diluent is the carrier or bulk of the liquid of the formula. For milk based formulations, skim milk may be used as the primary diluent. In milk free formulations, purified water is used.


A number of essential minerals are added to infant formula. These include calcium, phosphate, sodium, potassium, chloride, magnesium, sulfur, copper, zinc, iodine, and iron. Iron is one of the most important components since all babies need a source of iron in their diet. Some parents are concerned that iron-fortified formulas cause intestinal problems in infants but this is a myth. In general parents can expect formula fed babies to experience more gastrointestinal problems than breastfed babies.


Vitamins are added to increase the nutritional value of formula. These include vitamins A, B12, C, D, and E as well as thiamine, riboflavin, niacin, pyridoxine, pantothenate, and folacin.


A variety of materials are added to ensure the formula stays homogenous and that the oil and water soluble components do not

Once mixing is complete, the batch can be temporarily stored or transported via pipeline to pasteurization equipment. After pasteurization is complete, the batch may be processed further by homogenization.

separate. These include emulsifiers such as mono and di-glycerides as well as thickeners like natural starches and gums (e.g., such carrageenan.)

The Manufacturing

The method of manufacture depends on the type of formula being made. The following steps describe a general procedure for a ready-to-feed, milk-based formula.

Mixing ingredients

  • 1 The primary ingredients are blended in large stainless steel tanks. The skim milk is added and adjusted to 140° F (60° C). Fats, oils and emulsifiers are added next. Additional heating and mixing may be required to yield the proper consistency. Minerals, vitamins, and stabilizing gums may be added at various points in the process depending on their sensitivity to heat. Once mixing is complete, the batch can be temporarily stored or transported via pipeline to pasteurization equipment.


  • 2 Pasteurization is a process that protects against spoilage by eliminating bacteria, yeasts, and molds. Pasteurization involves quickly heating and cooling the product under controlled conditions which microorganisms cannot survive. A temperature of 185-201.2° F (85-94° C), held for about 30 seconds, is necessary to adequately reduce microorganisms and prepare the formula for filling. Several pasteurization methods are commercially available—one common method warms the formula by sending it through a tube adjacent to heat plate heat exchanger. Thus the formula is heated indirectly. Another method heats formula directly and then uses the heated liquid to preheat the rest of the incoming formula. The preheated formula is further heated with steam or hot water to the pasteurization temperature. After pasteurization is complete, the batch may be processed further by homogenization.

Homogen ization

  • 3 Homogenization is a process which increases emulsion uniformity and stability by reducing the size of the fat and oil particles in the formula. This process can be done with a variety of mixing equipment, which applies high shear to the product. This type of mixing breaks the fat and oil particles into very small droplets.


  • 4 The resulting composition is standardized to ensure key parameters, such as pH, fat concentration, and vitamin and mineral are correct. If any of these materials are at insufficient levels the batch can be reworked to achieve the appropriate levels. The batch is then ready to be packaged.

Conventional liquid filling equipment commonly used in the food and beverage industry are used to package ready-to-use baby formula.

  • 5 Packaging process depends on the manufacturer and type of equipment employed, but in general, the liquid formula is filled into metal cans which have lids crimped into place. These can be filled on conventional liquid filling equipment commonly used in the food and beverage industry.


  • 6 The filled packages can be subsequently heated and cooled to destroy any additional microorganisms. The finished cans are then packed in cartons and stored for shipping.

Quality Control

Quality of infant formula is ensured at three levels, which have some degree of overlap. First, in the United States, there are governmental standards, which establish the nutritional quality of infant formulas and other dairy substitutes. Specific details of these standards can be found in the Code of Federal Regulations; more information is available from the Food and Drug Administration (FDA) which regulates infant formula as a special diet food. The FDA publishes a monograph detailing everything from the mandated nutrient list to label copy and artwork used on packaging. Second, the dairy industry sets its own industry-wide quality control standards. The industry is self-policing and has its own regulatory organization, the International Dairy Federation, which sets industry standards for manufacturing and quality control. Third, individual companies set their own standards for quality control. For example Martek, one producer of triglycerides used in formula, has microbiologists and engineers monitor 30 different checkpoints of triglyceride production, 24 hours a day.

The Future

Future developments in infant formula manufacturing techniques will be driven, in part, by business and marketing concerns. This dependence on the marketing climate may be a benefit to the industry because there is tremendous opportunity for expansion. It is estimated that the total worldwide market for infant formula could be as high as $80 billion. Therefore, the current estimated world sales of formula of $4 billion represents only 5% of the total potential sales. Should the market grow even close to $80 billion, it is likely to spur manufacturers to find better ways to simulate breast milk. One such future improvement is being developed by scientists who have recently identified an important fatty acid in breast milk that is not found in infant formulas. This particular fatty acid appears to be important for the development of cell membranes in eye, brain, and nerve tissue. Addition of this material could be a significant advance in formula technology. Formula manufacturers can continue to make their products better by incorporating breakthrough research findings such as this one. However, even though there is great potential for growth, there is no guarantee it will be realized. The industry is experiencing criticism from groups which claim that formula is unnecessary and, in fact, may be harmful to infants. Should this trend negatively impact formula sales, manufacturers may be less likely to make significant investments in product and process development.

    While I understand the point you are making I think it’s also important to point out how awful the infant formulas on the market really are, even the organic ones. Almost all cans have BPA in them, yes even the organic ones. Baby formula is more than 50% corn syrup and are full of chemicals that are known to cause early puberty and cancer. Dairy based formulas have compounds that lead to milk allergies and soy is known to be dangerous when processed at high temperatures as well as being linked to early puberty as well. While it’s easy to tell parents they are putting their babies at risk by making their own formula you should also point out that we are not provided any safe options when it comes to store bought and they are still putting their babies at risk.

    Can a baby digest brewers yeast almond milk ? Sacha protein? Pond sum ? 0-6 mos digestive system is designed for breastmilk . If there is no breastmilk find a formula closest to breastmilk … tested and checked by the FDA. Why experiment on your baby . Maybe there is a better formula but until you see it proven it may be wise to not experiment on your baby.

    I for one don’t believe something created in a lab can be better than something from nature. I understand that not everyone is aware of bacteria that can be present whilst making homemade formula. However, Sterilization can go overboard its a fear mongering tactic. I wholeheartedly believe that one can create a healthy homemade version of baby formula. I wouldn’t call it experimenting either as I have met some mothers that have raised their babies on just that. Their immune system is stronger because of it! As a Vegan it would be important to me to not just give my baby dairy free but animal free formula. The FDA is not acting on all our best interests, this is been proven if we follow the money trail.

    What you’ve described is a highly processed food-like substance marketed to very vulnerable parents and fed to very vulnerable infants. It has almost nothing in common with “real food”. A safe, clean, and super nutritious homemade baby formula IS POSSIBLE!!! Just go to the Westom A. Price website and check it out! Don’t forget to read testimonials from parents whose children’s health completely turned around and become robust on these baby formulas.
