3. INTRODUCTION
• Tamarind (tamarindus indica.L) is a arboreal fruit belonging to the family
Fabaceae.
• Traditionally, tamarind pulp is extracted manually by hot water extraction
method.
• Now a days to increase the pulp recovery efficiency and maintain hygienist,
Hot enzymatic extraction is mostly adopted.
• Processed product like tamarind juice concentrate, tamarind toffee, sauce, jam,
tamarind drinks are made from tamarind paste.

5. Health Benefits of Tamarind
• Improves Nerve Function
• Helps Manage Diabetes
• Boost Immune System
• Treats Piles and Jaundice
• Helps in Blood Purification
• Controls Cholesterol Levels
• Prevents Hair Loss
• Help in Skin Care

7. Unit Operations for Preparing Tomato Paste
• Receiving:- We brought the raw material for the local market or by contact
farming, then weighed and stored.
• Storage:- The raw material (Tamarind) are stored in Raw material storage
section at 34°C(room temp).

8. • Delumping:-
The tamarind is delumped manually.
• Soaking:-
After delumping of tamarind, tamarind is soaked for 3-4 hr at 55oC
water in the ratio of 1:2 in soaking tank. Where one part is tamarind and two
part is water, Then enzyme is added. BEC foods use two tanks for soaking and
capacity of each is 1000 ltr.

9. Pulp Separation:-
• The heated pulp is conveyed via a special pump then send for extraction process,
there is a two operating station-
(a) De-stoner(with 6mm sieve size)
(b) Pulper(with 2mm sieve size)
(c) Finisher/refiner(with 0.6 to 1 mm sieve size)
• Destoner is used for removing seeds and large size fibers & extracting pulp from
soaked tamarind. It has 6mm sieve size, and
• In pulper, there is rotating body, down to it there is a sieve of size 2mm, So the
particle which have lesser than 3mm in mixture is get filtered through those sieve
and the remaining waste (seed, fibre, skin) are separated automatically.
• The Finisher is similar to pulper but there is a sieve of 1mm.

10. • Pre heating:-Pre-heating process is also known as pasteurization process at
which product is heated by indirect contact of steam at 85+/-2 oC for inactive
bacterial activity.
• Pulp Extraction:- Extraction is done by turbo extractor. The Turbo extractor
work same as a destoner & pulper/ finisher only difference is its Sieve size is
1mm. Its rotational speed is 2000 rpm.

11. Extraction Process :-
• The heated pulp is conveyed via a special pump then send for extraction process,
there is a two operating station-
(a) (b)Pulper(with 2mm sieve size)
(c) Finisher/refiner(with 0.6 to 1 mm sieve size)
• In pulper, there is rotating body, down to it there is a sieve of size 2mm, So the
particle which have lesser than 3mm in mixture is get filtered through those sieve
and the remaining waste (seed, fibre, skin) are separated automatically.
• The Finisher is similar to pulper but there is a sieve of 1mm.

12. Evaporation:-
• Evaporation process is done by three evaporators-
a) Plate Heat Exchanger Type Evaporator (at 80ᵒC ) or PHE
b) Forced Circulation Evaporator(3-effect) (at 80ᵒC )
c) Scrap Surface Evaporator(at 80ᵒC )
• In these evaporators tamarind pulp is heated at 80 ᵒC by steam and remove the
water molecules and the output pulp is concentrated at 30-34° Brix and
according to the required brix range the pulp will be concentrated and then the
pulp is send aseptic section for sterilization.

13. Sterilization:-
In this section the juice is sterilized and the bacteria’s are fully destroy , Four
sterilization process are-
I. Heating(by steam at 103ᵒ C temp.)
II. Holding(for 3min)
III. Cooling(by normal water)
IV. Chilling(by water with 5ᵒ C )

14. Aseptic Filling & Storage:-
In this section after the removing of cap the HDPE bags are sterilized by
steam and after that the pulp is filled in this bags and then is recapped and drop
in drums. And then stored in 4°C to 10°C(room temp.).
