What is the difference between cornstarch and maize starch?
The short answer is maize starch is the same as corn flour made from corn (like the photo of my yummy backyard produce). Cornflour from corn = maize starch and is very low in protein (~0.3 g/100 g). In other countries corn can mean the locally grown crop (confusing the issue even further) so it might not be maize.
What is waxy maize…and why do you need it?
Waxy maize is a dietary supplement that will benefit strength training athletes in a few ways. It will provide you with sustained energy levels, increase your endurance, increase your rate of recovery and help you quickly restore glycogen levels that are depleted during your workout.
Is corn starch the same as maize starch?
Corn starch, also known as maize starch, is starch that comes from corn kernels.

Is waxy maize just corn starch?
What Is Waxy Maize Starch? Before we get to the actual myth, we should take a look at what we're talking about. In fact, some of the mythology lies in the fundamental misunderstanding of what WMS really is. Waxy starches are carbohydrates derived from various sources such as rice, barley, and corn (i.e. maize).
What is the difference between cornstarch and waxy maize?
Common corn starch has 25% amylose, while waxy maize is almost totally made up of amylopectin. The two remaining corn starches are high-amylose corn starches; one has 55% to 55% amylose, while the second has 70% to 75%.
What is waxy maize in baking?
Waxy maize starch is noted for its good expansion properties. It is well suited for puffed cereals, baked chips and cakes. In filling applications where boil-out and heat stability are issues, waxy maize starch is recommended because it is thicker than other starches, which helps reduce boil-out.
What is waxy maize good for?
Most of the benefits of waxy maize starch come from its slow digestibility. Waxy maize starch has an average molecular weight 100 times greater than carbohydrates and contains no simple carbohydrates or monosaccharides. It may help improve exercise performance, promote recovery, and improve diabetes management.
Is waxy maize resistant starch?
In vitro research documents that waxy maize is a slowly digested starch [6].
Is maize contain starch?
The major chemical component of the maize kernel is starch, which provides up to 72 to 73 percent of the kernel weight. Other carbohydrates are simple sugars present as glucose, sucrose and fructose in amounts that vary from 1 to 3 percent of the kernel.
Is waxy maize sugar?
WHAT IS WAXY MAIZE STARCH (AMYLOPECTIN)? The amylopectin or waxy maize starch, is a complex carbohydrate, which contains no sugar and no lactose. It brings us high benefits, as it restores glycogen levels more quickly than dextrose, but without the caloric intake of sugar.
What is waxy maize vs dextrose?
Waxy Maize (starch) is a slow digesting carbohydrate, where Dextrose and Maltodextrin are fast digesting carbohydrates. With a glycemic index of 63, Waxy Maize absorbs slower, raising blood sugar levels more slowly and in the process reducing the chances of a spike then crash in energy versus Dextrose and Maltodextrin.
Is waxy maize starch gluten-free?
Generally, modified food starch is made from corn, waxy maize and potatoes, meaning that those types are gluten-free. Modified food starch may contain wheat.
Is waxy maize good for diabetics?
Nutritionists have found that waxy corn may be a suitable source of carbohydrate for maintaining glucose control in insulin sensitive individuals (Sands et al., 2009) .
How is waxy corn starch made?
Starch Mutants: Waxy Corn Waxy corn and high-amylose corns differ from normal varieties in their proportions of amylose and amylopectin. Waxy corn, a genetic mutant, contains starch composed entirely of amylopectin. A few corn wet mills process these special hybrids and market the waxy starch into niche markets.
Is dextrose the same as maltodextrin?
What is the difference between dextrose and maltodextrin? Dextrose is composed of one sugar, while maltodextrin is a polysaccharide. In other words, the latter is a more complex form of sugar. If you're looking for a quick boost of energy during your workout, dextrose is converted to glucose faster in the body.
What is waxy corn starch?
Waxy corn starch, also known as waxy maize starch, consists of only amylopectin molecules, giving this star ch different and useful properties (see Chapter 3 ). This genetic variety of corn was discovered in China in the early 1900s, when corn plants were transferred from the Americas. The starch stains red with iodine, ...
What is waxy corn?
Waxy corn, a genetic mutant, contains starch composed entirely of amylopectin. A few corn wet mills process these special hybrids and market the waxy starch into niche markets. Higher prices paid for these specialty starches warrant the increased costs of contract production and identity preservation.
What are the effects of modification sequence on chemical structures and physicochemical properties of hydroxypropylated
The effects of modification sequence on chemical structures and physicochemical properties of hydroxypropylated and cross-linked waxy corn starch were recently reported (Wang and Wang, 2000 ), where the chemical structures of dual-modified starches and their β -limit dextrins were characterized with high-performance liquid-chromatography. The hydroxypropylated-cross-linked starch had higher Brabender viscosity than did the cross-linked-hydroxypropylated starch at both pH 7 and 3; but both starches has similar gelling properties. The hydroxypropylated-cross-linked starch had significantly higher onset and peak gelatinization temperatures, gelatinization enthalpy, and lower retrogradation. Also, the latter starch exhibited a significantly higher β -amylolysis limit and higher content of low molecular weight saccharides in its isoamylase-debranched starch, suggesting a structure more accessible to en zymatic digestion than that of the cross-linked-hydroxypropylated starch. Further structural analyses revealed different distribution patterns of modifying groups between the two modified starches. The results indicated that the modification sequence was responsible for changing the susceptibility to enzymes, the locations of substitution, and the physicochemical properties of the hydroxypropylated and cross-linked wx corn starches. Shi and Be Miller (2002) recently evaluated the aqueous leaching of the hydroxypropylated common corn starches at different times and temperatures. Results indicated that the greater the modification the easier it was for AM to leach out and that the preference for leaching of derivatized AM decreased as molar substitution of the whole starch increased.
What are the two polysaccharides in corn starch?
It is obtained in the form of granules that have varying degrees of structural order and consists of two polysaccharides, namely, amylose and amylopectin. The proportions of each depend on the source, for example, corn and potato starches contain ~ 27% and 21% amylose, respectively, while waxy corn contains < 2% amylose.
What temperature do corn starches get?
The typical values for corn and potato starches are 67 °C and 60 °C, respectively. On cooling, the amylose molecules readily self-associate, a process known as retrogradation, and it is then that a gel is formed. Natural starches form turbid gels that are prone to syneresis.
When was waxy corn first discovered?
6 Improvement of Starch Sources (See Also Chapter 3) Amylopectin-rich corn was first found in China in 1908 . It was called waxy corn due to the appearance of the kernels. At first it was only maintained as a genetic curiosity, although its pasting properties were known to be similar to that of tapioca starch.
When was waxy corn invented?
In the 1940s, geneticists at Iowa Agricultural Experiment Station developed waxy corn into a high-yielding hybrid. After waxy corn was introduced as a contract crop, its starch developed rapidly into a valuable food starch.
What is the name of the starch in waxy maize?
Weatherwax of Indiana University in Bloomington, reported that the starch in waxy maize was entirely of a “rare” form called “erythro dextrin ”, known today as amylopectin. He found that this rare starch stained red with iodine, in contrast to normal starch which stained blue.
What is waxy corn?
Waxy corn or glutinous corn is a type of field corn characterized by its sticky texture when cooked as a result of larger amounts of amylopectin. The corn was first described from a specimen from China in 1909.
What was the main source of starch in the USA?
Until World War II, the main source of starch in the USA was tapioca but when Japan severed the supply lines of the States, they forced processors to turn to waxy maize. Amylopectin or waxy starch is now used mainly in food products, but also in the textile, adhesive, corrugating and paper industry.
Why is waxy starch so expensive?
Waxy starch is of main interest because fractionation of normal starch to obtain pure amylose or amylopectin is very costly. Waxy endosperm is inherently a defect in metabolism, and its low frequency in most maize populations in the face of recurring mutations indicates that it is acted against by natural selection.
How many tons of waxy maize were produced in 1943?
In 1943, to cover all the special requirements for amylopectin, approximately 81650 tons of grains were produced. From World War II until 1971, all the waxy maize produced in the U.S. was grown under contract for food or industrial processors.
How much maize was produced in 2002?
In 2002, an estimated 1,200,000 to 1,300,000 tonnes of waxy maize was produced in the United States on about 2,000 km², representing only 0,5% of the total maize production.
When was waxy maize first fed?
The research in feeding of waxy maize began in the 1940s. Beginning with a research report in 1944, waxy maize seemed to have the potential to increase feed conversion efficiencies compared to dent maize. Many other feeding trials were started and generally indicated a slight to clear positive advantage for feeding waxy grain. Increases of both milk production and butterfat content for lactating dairy cattle, increase in daily weight gains in fattening lambs and when fed to finishing beef cattle.
Is waxy maize a scam?
Here’s the Truth: Waxy Maize Starch is a complete and utter SCAM. Any company carrying it is a complete an utter liar and scumbag, cheating company…geez can I get any more clear. Do not buy waxy maize starch, it is SNAKE OIL!
Is waxy maize starch better than maltodextrin?
It also goes by the name modified food starch. It also goes by the name of corn starch. Thus modified corn starch. Therefore waxy maize starch is no better than maltodextrin and dextrose.

Is Cargill starch thickening?
With growing interest in familiar ingredients and simpler labels, native starches are a logical choice for texturizing and thickening. Some Cargill products are only approved for use in certain geographies, end uses, and/or at certain usage levels.
What Is Waxy Maize starch?
- Before we get to the actual myth, we should take a look at what we're talking about. In fact, some of the mythology lies in the fundamental misunderstanding of what WMS really is. Waxy starches are carbohydratesderived from various sources such as rice, barley, and corn (i.e. maize). The "waxy" part refers to the fact that under a microscope there ...
The Myth Itself
- Now that we understand what we're talking about, it's time to look at the actual tale. Essentially, the myth states that WMS is a very fast carbohydratebecause of its high amylopectin component (>99%), and subsequent enormous molecular weight (this explains why some companies simply call their WMS "amylopectin"). It's further stated that because of this molecular weight, WMS is a…
The WMS Study Summaries
- The first study compared way maize to dextrose, slow starch, and a placebo (4). In contrast to common claims, following ingestion, both blood glucose and resulting insulin levels were similar between WMS and slow starch, and 3 times lower than plain dextrose. Measured work output during cycling exercise was not different following either dextrose or WMS ingestion, which wer…
A Leap of Faith
- Looking at the above summaries there seem to be discrepancies. After all, the responses range from being slightly worse than dextrose (5), to much worse than dextrose (4) or sugar and maltodextrin (1), to even worse than bread (10). While none of these probably make you want to use WMS, or support the predominant claims about it, the differences are enough to make you w…
Full Investigation
- To reiterate, not only do the available data fail to support any of the claims made about WMS, they seem to contradict it! At this point I began to feel as though I was missing something. So just to make sure that I covered everything, I contacted 5 of the biggest supplement companies that sell WMS products. Sadly, in spite of their claims, those that actually tried to help me couldn't provid…
The Myth Is Spawned
- So where did this myth come from? After all, there has to be something to it if it's as pervasive as it is. The fable was actually created from the erroneous application of two very powerful carbohydratestudies (7, 9). These studies used a carbohydrate extract called Vitargo, and were referenced on the label of a now-defunct product containing this carb. When we looked at the la…
Conclusions and Questions
- So in spite of hours of investigation, I just couldn't find any reason to use WMS. Even speaking to a dozen or so people from the companies that sell it, couldn't provide me with one single study about this substance. Worse than simply not being able to justify claims about its rapidity, most of the available information suggests that WMS is a poor carbohydrateto use after training. To put …
Do You Work For A Competitor Who Wants to Hurt WMS Sales?
- Sadly no. The 100+ hours I've put into this investigation are all pro bono. I'll consider it penance for having mentioned WMS in the past. Interestingly, even if I were the CEO of a competing company, it wouldn't impact the scientific literature or the unsupported claims.
Overview
Waxy corn or glutinous corn is a type of field corn characterized by its sticky texture when cooked as a result of larger amounts of amylopectin. The corn was first described from a specimen from China in 1909. As this plant showed many peculiar traits, the American breeders long used it as a genetic marker to tag the existence of hidden genes in other maize breeding programs. In 1922 a resear…
History
The exact history of waxy maize is unknown. The first mentions of it were found in the archives of the U.S. Department of Agriculture (USDA). In 1908, the Rev. J. M. W. Farnham, a Presbyterian missionary in Shanghai, sent a sample of seeds to the U.S. Office of Foreign Seed and Plant Introduction. A note with the seeds called it: "A peculiar kind of corn. There are several colours, but they are said to be all the same variety. The corn is much more glutinous than the other varie…
Biology
Collins noted, among others, these unusual traits of the Chinese maize:
• Several unique structural features that enabled the plants to resist the drying out of the silks by wind at the time of flowering
• Unusual growth behaviour in that the top four or five leaves all appeared on the same side of the main stem of the plant. Extremely erect leaves of the upper nodes, while the lower leaves were more spread and drooping
Genetics
Genetic research of this genetic drift started first with describing the physical appearance (phenotyping) of the mutant maize. Later on these phenotypes were coupled to mutant genes genotypes. More than 40 mutant alleles are known for the waxy locus, making up the finest collection of mutations found among higher plants.
Some of these waxy mutants are very stable whereas others are very unstable. The genotype of …
Genotype and characterisation with iodine
The wx locus is expressed in the endosperm, in the male gametophyte (pollen) as well as in the female gametophyte (embryo sac). Amylose and amylopectin have different iodine binding-properties, with maize amylose and amylopectin giving iodine affinity (IA) values of about 19 to 20 and 1%, respectively, depending upon the source. Weatherwax discovered this process in 1922.
The amount of apparent amylose can be determined either by measuring the absorbency of the …
Biochemistry
Normal dent maize has two different pathways for starch formation one leading to branched chain (amylopectin) and the other to straight-chain polysaccharides (amylose).
• The amylopectin consists of chain of α-D-(1-4) and α-D-(1-6)-glucosidic linkages that form a branched molecule.
• Amylose is primarily linear with α-D-(1-4)-linked glucose residues.
Agronomic features
Producing waxy maize starch on an industrial scale requires extra measures compared to standard dent maize.
New varieties with the waxy locus are relatively easy to breed through back-crossing breeding with dent maize varieties, but their productivity is approximately 3 to 10% less than that of dent maize.
Utilization
Amylopectin or waxy cornstarch is relatively easy to gelatinise, produces a clear viscous paste with a sticky or tacky surface. The paste rheology resembles pastes of root or tuber starches, such as potato starch or tapioca starch (made from cassava). Amylopectine starch have also a lower tendency to retrogradate and are thus more viscosity stable. These different properties compared to nor…
