1. Koozhu
Place of origin/usage: Tamil Nadu.
Nature of food: Cereal based.
Time of consumption: Break fast and festival seasons.
Importance of the food: Easily digestible and cause cooling of the body.
Usual composition/ingredients: A cup of Eleusine coracana (ragi) flour, a couple of
tablespoons of boiled rice, half cup of non-fat yoghurt/buttermilk and a table spoon of
crystal salt.
Method of cooking: A cup of Eleusine coracana (ragi) flour is nicely mixed with two cups
of water and left overnight to sour. It is cooked using medium-low heat till most of the
water is evaporated and ragi is well cooked. It has to be continuously stirred every second
to avoid formation of any lumps. Water can be added if needed. When the koozhu is in
the right consistency (cake batter consistency), a tablespoon of cooked rice is added. The
cooking is stopped and allowed to cool. The preparation is mixed with half a cup of
yoghurt and salt for consumption.
Related/Varied forms of the food: Koozhu made with sorghum, pearl millet, little millet
and foxtail millet.
Method of consumption: Consumed with side dishes such as black-eyed beans curry
(‘Karakozhambu’ in Tamil Language), dried fish curry (‘karuvaatu kozhambu’ in Tamil
language) or fish curry.
2. Fermented rice
Place of origin/usage: Tamil Nadu.
Nature of food: Cereal based.
Time of consumption: Breakfast.
Importance of the food: Easily digestible.
Usual composition/ingredients: Rice, curd and salt.
Condition(s) of fermentation: Overnight duration at 30-32°C.
Microorganism(s) involved: Streptococcus faecalis (2.7x107gm
-1), Pediococcus
acidilactici (2.7x107gm-1), Bacillus sp. (1.6x108gm-1) and Microbacterium flavum (1.1 x
108 gm
-1).
Method of preparation: Water is added to cooked rice and allowed to ferment overnight.
Changes in physical and chemical profile: There is no change in volume, amino nitrogen
or free sugar. The pH decreases from 6.1 - 5.7 in 16 hours.
Other usages: After fermentation, the water is drained off from the rice and used for
cooking vegetables or mixed with butter milk and salt and consumed directly.
Reference(s): Ramakrishnan 1977; 1979.
3. Idli
Place of origin/usage: South India.
Nature of food: Cereal and pulse based.
Time of consumption: Breakfast and snack.
Importance of the food: Low calorie starchy food having high degree of acceptability in
South India. Batter is protected against food poisoning and pathogenic organism due to
acidity. It is globally used with various combinations of cereals grains and pulses.
Usual composition/ingredients: Three or four parts of rice to 1 part of black gram dhal
(either raw or parboiled rice) plus table salt (0.8-1%). Some prefer to add one tablespoon
of fenugreek seeds per kg of rice to get smooth idlies. It is processed along with dhal.
Preferred quality of raw materials: Rice with 22% amylase (to avoid low amylase
content and waxy rice) is preferred. Normally, high amylase content and gelatinization
temperature coupled with low amylopectin content and water uptake activity is desirable.
Method of preparation of initial batter/raw materials: White polished rice and black
gram dhal are carefully washed and soaked for 5-10 hours. The rice is then drained and
coarsely ground in a stone mortar or grinder. The black gram dhal is then drained and
finely ground in a stone mortar. During grinding, water is added to 1.5 to 2.2 times initial
dry weight of the rice and black gram. The rice and black gram slurries are combined to
form a rather thick batter which is stirred with the hands. Salt (approximately 1% w/v) is
added to taste. The batter is placed in a warm place to ferment overnight.
Nature of fermentation: Acidic fermentation due to the major role played by Lactic Acid
Bacteria (LAB).
Condition(s) of fermentation: Usually overnight duration at 30-32°C
Microorganism(s) involved: Leuconostoc mesenteroides and Streptococcus faecalis are
the dominant microorganisms. The other organisms are Saccharomyces cerevisiae,
Debaromyces hansenii, Hansenula anomala, Torulopsis candida, Trichosporon beigelii
and Pediococcus cerevisiae.
Other organisms tested for fermentation: Lactobacillus fermentum, Torulopsis sp.,
Candida sp. and Trichosporon pullulans.
Whether native fermentation or inoculum is added: Usually native LAB microflora
rises up. Some reported addition of sour butter milk or commercial yeast pellets.
Method of cooking: The batter is poured into cups of an idli steamer which is placed in a
covered pan. It is steamed until the starch is gelatinized and the idli cakes become soft
and sponge.
Nutritional profile of food: 3.4% protein, 20.3% carbohydrate, and 70% moisture,
1% verbacose, 0.2% stachyose and raffinose.
Changes in physical and chemical profile: Leavening due to the generation of CO2
causes softness in idli. Batter volume increases by 113%, pH fell to 4.5%, total acidity
rises to 2.8%, reducing sugar decreases to 0.8 mg/g, protease activity and amino nitrogen
increases, phytase phosphorous and phytic acid content decreases.
Improvement of flavour: Formation of ketones, dioles and acids due to fermentation.
Related/Varied forms of the food: Kancheepuram idli (1 part of rice to 1 part of black
gram dhal plus cashew nuts, ghee, salt, pepper, ginger and cumin added to taste). Idli
with the cereal Paspallum scrobiculatum (kodo) or finger millet or foxtail millet instead
of rice, idli with green gram or Bengal gram or soybean instead of black gram are known.
Fried idli and Idli uppuma are products obtained using idli.
Anti-nutritional Factors in Idli
Fermentation processes appear to have a significant effect on elimination and/or
reduction of antinutrients (phytic acid and enzyme inhibitors) and the flatulence problem.
A reduction of 35.0-40.0% of phytic acid was reported during idli preparation.
Fermentation and steaming also resulted in appreciable reduction (33.8%) of
oligosaccharides (verbascose, stachyose and raffinose) in idli. The final product contains
1.0% verbascose and 0.2% stachyose and produces low flatus (8.4 ml Ht) in rats, when
fed to rats at a 50% level in the basal diet. Chymotrypsin inhibiting activity can be
eliminated completely by fermentation and steaming during the preparation of idli but not
the trypsin inhibiting activity. No hemagglutinating activity is found in the idli.
Storage of idli batter
A commonly observed phenomenon with idli batter is whey separation that occurs
due to collapse in its volume after a certain period of fermentation and which increases
with storage. Idlis made from such batter give a very hard texture. The stabilization of the
idli batter at room temperature (28-30°C) and refrigerated storage (4-8°C) by using
various hydrocolloids and some surface active agents were analysed. The batter was
evaluated in terms of percentage decrease in volume, and percentage of whey separation.
While hydrocolloids gave good stabilization, surface-active agents failed to stabilize the
batter although they reduced whey separation. Among the various hydrocolloids, 0.1%
guar gave best batter stabilization. Idlis made there from after 10 days of room
temperature and 30 days of refrigerated storage of batter were found to be of acceptable
quality.
The desirable flavour compounds such as ketones, diols and acids were found to
be present up to 8 days of storage, whereas undesirable flavours like sulphurous and
oxazolidone compounds, ethanone and thiazole appeared in the batter subsequent to 6
days of storage (Agarwal et al., 2000).

Changes in physical and chemical profile: There is an almost two fold raise in the batter
volume and a drop of pH from 5.2 to 4.5. The yeast produces folic acid and raises the
volume of the batter, imparting sponginess to the product.
Related/Varied forms of the food: Channa dal dhokla
Reference(s): Ramakrishnan et al., 1976, Aliya and Geervani 1981, Chavan and Kadam
1989, Kanekar and Joshi 1993, Blandino et al., 2003, Roy et al., 2007 (a).
Effects of fermentation in idli, dosa and dhokla
a) Bio accessibility of Zinc
After fermentation, batters of idli and dosa showed significantly higher
bioaccessibility values for zinc. The value of zinc bio-accessibility is as high as 71% in
idli and 50% in dosa. Such an increased bio-accessibility of zinc, however, was not
evident in the case of fermented dhokla batter; instead there was a slight decrease (10%).
In the case of idli, the zinc bio-accessibility value, although higher (27%) than that of
unprocessed grains, was lower (26%) than that of the uncooked fermented batter. In the
case of dosa, the zinc bio-accessibility value similarly decreased upon heat processing of
the fermented batter (46% lower), and this value was 18% lower than that of the
unprocessed grains. In the case of dhokla, the zinc bio-accessibility value decreases by
23% upon heat processing of the fermented batter. This final value being 31% lower than
the unprocessed grain combination (Hemalatha et al., 2007).
b) Bio accessibility of iron
Fermentation of the combination of rice and black gram in both idli and dosa
enormously improved the bioaccessibility of iron. Bioaccessible iron in the fermented idli
batter was 276% higher and that in the dosa batter was 127% higher compared to the
untreated grains used. Heat treatment of the batter further increased the bioaccessibility
of iron by 92% in the case of dosa, while that in the idli batter did not change. Thus,
fermentation and heat processing as in the preparation of dosa resulted in a net increase
of 335% in the bioaccessibility of iron from the rice–black gram combination.
Fermentation of a combination of chickpea, green gram, black gram and rice as in the
preparation of dhokla, however, did not improve the bioaccessible iron content. Heat
processing of the fermented batter of dhokla also did not alter the bioaccessible iron
content; thus, the bioaccessible iron value of dhokla remained the same as that of the
native grain combination used. A reduction in the pH by 1.5 units as a result of
fermentation of the batter of idli, dosa and dhokla was observed (Hemalatha et al., 2007).
c) Reduction of phytic acid content
Typical food processing methods such as germination and malting have been
found to enhance iron absorption due to elevated vitamin C content or reduced tannin or
phytic acid content, or both (Tontisirin et al., 2002). These processes are known to
activate phytases, which in turn hydrolyze phytate, rendering iron and zinc more
available. During germination, endogenous phytase activity in cereals and legumes
increases as a result of de novo synthesis and/or activation, resulting in reductions in
inositol penta- and hexa-phosphates depending on the species and variety (Lorenz, 1980;
Chavan and Adam, 1989; Reddy et al., 1989). Reddy et al. (1989) have reported
reductions in phytate ranging from 36% for sprouted soya beans to 53% for germinated
lentils. In addition, germination also reduces the content of polyphenols and tannins in
some legumes (Camacho et al., 1992).
Microbial fermentation can enhance iron and zinc bioavailability via hydrolysis of
phytate by microbial phytase derived from naturally occurring microflora on the surface
of cereal grains (Sandberg, 1991). The beneficial effect of fermentation on mineral
bioavailability could also be attributed to the formation of organic acids during this
process, which form soluble ligands with iron and zinc (Tontisirin et al., 2002). This
reduction in pH is certainly due to the synthesis of organic acids during fermentation.
Natural fermentation of cereal–legume combinations significantly reduced both
phytate and tannin from the test grains. Phytate was completely removed during
fermentation of the idli batter, while the reduction was 50 and 28% during fermentation
of dosa and dhokla batter, respectively. Only traces of tannin were detectable in the
fermented batters of idli, dosa and dhokla. The absence of any positive influence of
fermentation on mineral bioaccessibility in the case of dhokla batter could be attributed to
the continued presence of significant amounts of phytate. The additional legumes –
chickpea and green gram – present in dhokla apart from rice and black gram (constituent
grains for idli and dosa) have contributed to this significant phytate content (Hemalatha
et al., 2007).

Usual composition/ingredients: Par-boiled rice (Oryza sativa L.) and black gram
(Phaseolus mungo L.).
Alternative composition/ingredients: Black gram may be substituted with juice of
jackfruit (Artocarpus heterophyllus Lam.) or palmyra palm (Borassus flabellifer L.) fruit
during summer.
Method of preparation of initial batter/raw materials: Rice is washed, soaked,
dewatered and briefly sun-dried. Dried rice grains are pounded in an iron or wooden
mortar and sieved to obtain a fine powder. Black gram is soaked until the seed coat is
easily removable by applying a gentle pressure. The grains are rubbed with hands to
loosen seed coats, which are allowed to float away. The black gram is then made to a
smooth paste using a stone grinder. The paste is beaten repeatedly by hands with a little

17. Munha pitha
Place of origin/usage: Orissa.
Nature of food: Cereal and pulse based.
Time of consumption: Festival seasons.
Usual composition/ingredients: Par-boiled rice powder and black gram.
Method of preparation of initial batter/raw materials: Par-boiled rice powder and black
gram paste are mixed in the ratio of 3:1. Sugar or jaggery, minced coconut, raisins and
cashew nuts may be added to the fermented batter for delicacy.
Method of cooking: Sufficient water is taken in a large-mouthed pitcher (‘handi’) and a
piece of cloth is tied over its mouth keeping a shallow cavity. When the water starts
boiling, a thick batter is poured over the cloth. An empty handi is kept upside down over
the previous one to capture the steam. The continuously generated steam cooks the
material and completion of cooking is checked by inserting a sharp object through the
centre of the batter mass and observing if the batter has stuck to the surface. No
adherence of batter to the object indicates completion of cooking even at the centre. A
good quality munha pitha becomes spongy like idli and it is served by cutting into pieces.
Method of consumption: It is taken with sugar or curry.
