5. WHAT IS LAC?
Lac is the hardened resin, secreted by the
tiny lac insect belonging to a bug family. The widely known Indian lac insect is
Kerria lac Kerr (Tachardiidae: Homoptera) although the lac insect of
Thailand is Kerria chinensis. Lac insects settle closely on the twigs
of certain host trees, suck the plant sap and grow, all the while secreting lac
resin from their bodies. Since the insects are closely spaced on the twigs, the
resin forms continuous encrustations over the twigs of the host trees. These
insects thrive only on certain trees, which are called host trees. In
India, the major hosts trees are Scheleichera oleosa, Butea
monosperma and Zizyphus mauritiana, while the major lac host of
Thailand is Samanea saman.
6. HOW IS LAC PRODUCED?
Lac cultivation is done by putting sticks of
lac encrustations (broodlac) which contain mature female (gravid)
insects, which are about to give birth to young larvae, on suitably prepared
specific host plants. After emergence from the mother cells, the young larvae
settle on the fresh twigs of the host plants, suck the plant sap and grow to
form encrustations. The twigs containing these encrustations are harvested after
they are fully grown to extract the lac resin.
Lac cultivation is simple, does not need any
large investment and requires only part-time attention. Sustained production and
steady returns can be achieved by adopting improved methods of cultivation.
Thus, lac cultivation can be an extremely attractive avocation.
7. HOW IS LAC PROCESSED?
Lac encrustations are removed from the twigs
of host plants by scraping. The raw lac thus obtained is known as scraped
lac or simply sticklac. Sticklac is crushed into small grains,
seived, washed with mild alkaline water and dried. This semi-refined product,
called seedlac, is further refined by a system of hot melting,
filtration and stretching into thin sheets which are subsequently broken into
brittle flakes called shellac. Alternatively the purified lac resin can
be in the form of circular discs called button lac. If a solvent
process is used to purify the raw lac, dewaxed, decolourised lac can be
obtained as the end product. The normally amber coloured resin can also be
bleached with sodium hypochlorite to obtain bleached lac, which is
white in colour. Bleached lac has specialised demand for coating medicinal
tablets, confectioneries etc.
India is the principal lac producing country
of the world, producing approximately 18,000 metric tonnes of unrefined (raw )
lac annually. About 85% of the country's production is exported to various
countries. The USA, Germany and Egypt are some of the major lac importing
countries of the world.
Export of lac from India is mainly in the form of
:
- Shellac / button lac
- Seedlac
- Dewaxed lac
- Bleached lac
-
Aleuritic acid
8. WHAT IS LAC COMPOSED OF?

Lac is generally processed either by
hand (country process) or by suitable machines. Accordingly, the following
grades of hand-made seedlac are commonly available in the market: (1)Ordinary/genuine
bysakhi (2) Fine bysakhi (3) Golden bysakhi (4) Golden
kusmi (5) Golden bysakhi – bold grain (6) Golden kusmi
– bold grain (7) Golden kusmi seedlac – medium and (8) Manbhum
fine seedlac (Note: In
the lac trade, baisakhi crop is commonly referred to as bysacki or bysakhi)
The following grades of hand made
shellac are also available in the market: (a) Lemon one
(b) Lemon two (c) Standard one (d) Superior lemon
(e) Superior kusmi lemon (f) Kusmi buttonlac
(g) Superior kusmi buttonlac (h) Light pure buttonlac and
(i) Pure one buttonlac

The solvent process of lac manufacture
yields the following grades: (a) Platina (b) Super Blonde (c)
Blonde (d) Super Blonde (e) Dewaxed Lemon (f) Dewaxed
Orange and (g) Dewaxed Garnet. Actually, the above
nomenclature is based on the colour of the lac product. For instance, the
colour index of Platina is about 0.6 and for Garnet is 35. Colour indices
of the other varieties fall in-between the above two extremes.

12. WHAT IS THE IMPORTANCE OF LAC?
Lac has been in use in India since the
Vedic period. The Atharvaveda contains a complete chapter on lac,
with detailed descriptions of lac insects and the medicinal uses of the
resin. The great Indian epic Mahabharata gives an account of the
Lakha Griha, an inflammable house of lac, cunningly
constructed by the Kauravas for the purpose of vanquishing their enemy.
Since ancient times, lac has been used for some purpose or the other. Lac
yields, besides resin, other useful products such as lac dye and lac wax.
But their applications have been changing with time. Lac resin, dye etc.
still finds extensive use in Ayurveda and Siddha systems of medicine
With increasing universal environment
awareness, the importance of lac has assumed special relevance in the
present age, being an eco-friendly , biodegradable and self-sustaining
natural material. Since lac insects are cultured on host trees which are
growing primarily in wasteland areas, promotion of lac and its culture can
help in eco-system development as well as reasonably high economic
returns.
13. WHAT ARE THE EDIBLE APPLICATIONS
AND SAFETY ASPECTS OF LAC?
The edible, bio-degradable,
self-sustainable, odourless and flavourless properties of lac have made
this material ideal for food processing and packaging applications. On 26th
July 1989, the United States Food
& Drugs Administration published a proposed rule, for affirming that shellac
and shellac wax,
were generally recognised as safe (GRAS), with specific
limitations for use as a direct human food additive. The shellac, would
have to be, of appropriate food grade.Substances approved for addition to
foods by the US FDA are listed in Title 21 of the Code of
Federal Regulations (21 CFR). Shellac is regulated as an Indirect
Food Additive in 21 CFR §175.105 (Adhesives) and §175.300
(Resinous & Polymeric Coatings). Indirect additives are
substances used in food and include Adhesives and components of
coatings (Part 175), Paper and paperboard components used in
contact with aqueous and fatty foods (Part 176), Polymers
(Part 177) and Adjuvants and Production Aids (Part 178).
Shellac is also listed as a Diluent in Colour Additive
Mixtures for Marking Food Supplements in tablet form, gum and
confectionery under 21 CFR §73.1(b)(1)(i). It is also discussed in 21 CFR
§101.4(b)(22), in terms of declaring the ingredient as a food label.
As per FDA regulations, if fruits and vegetables are coated as above, the
information has to appear on the labels of individual products, packing
cartons etc. The information will clearly state that the product is
either:
- Coated with food-grade animal-based wax to
maintain freshness, or
- Coated with food grade vegetable /
petroleum / beeswax / and / or shellac- based wax or resin to maintain
freshness.
If any one of these types of
waxes is applied, the label can simply identify the type, such as
“vegetable-based”. The FDA also allows the statement “No wax or
coating” on fresh produce that does not contain wax. As per FDA
regulations, the term “lac resin” may be substituted for the term
“shellac”. The reviewers of the Technical Advisory Panel (TAP)
of the National Organic Standards
Board (NOSB) of the US Govt.
also reviewed shellac in September 1999 and concluded that it could be
allowed in products labeled “made with organic ingredients”.
Similarly, the FDA
classifies all colour additives in food as Certifiable or Exempt
from Certification. Certifiable colour additives are man-made; colour
additives exempt from certification include pigments from natural sources,
such as vegetable dyes, and even man-made natural derivatives of natural
colours. Lac dye (Merck Index 5342) has been identified as the red
dye found in lac. The related colour is cochineal extract, the lake of
which is carmine. Cochineal extract and carmine are regulated as colour
additives exempt from certification in 21 CFR §73.100. Within this code,
the identity, specifications, uses and restrictions, labeling requirements
and exemption from certification are listed.
Food Additives in the
European Union are categorised under 3 Directives viz. Sweeteners, Colours and
Food Additives other than Colours and Sweeteners.
Details of EU law can be obtained in the homepage of the European
Commission. Details of Miscellaneous
Food Additives of England, Scotland, Ireland and Wales are also
available. The UK Food
Standards Agency also publishes
a listing
of E numbers, Shellac is
classified as E 904, whereas cochineal, carminic acid and the carmines are
listed as E120. Ponceau 4R and Cochineal Red A are listed as E 124. As in
the case of US FDA, no separate listing is available for lac dye. The
above numbering system has been adapted for international use by the Codex
Alimentarius Commission, who are developing an International
Numbering System (INS), which uses the same numbers but without the E prefix.
The code no of shellac under
the Australia New Zealand Food
Standards Council is
904 /E904@ (“@” denoting that the product is of animal origin), as a
food additive used as a glazing agent, in chocolates, confectionery, fizzy
drinks, medications etc. No separate coding is available for lac dye.
Cochineal and carminic acid (carmines) are listed as 120 / E122@ as food
colours. Approved food additives in Australia / New Zealand are coded in a
similar way to the food additives permitted by the EU, but they are not
always the same (see above).
The Food
Additive Hygiene Standards of China
approves shellac (code no. 14.001) for use as a coating agent in the
manufacture of chocolates and waffles with a maximum dosage of 0.20g / kg
body weight. It also approves the use of lac dye (code no. 08.104) as a
colouring agent in fruit/vegetable drinks, carbonated drinks, blended
wines, candies, fruit jams, condiments and sauces, with a maximum
permissible dosage of 0.5g/kg body weight.
