Seven-up Bottling Company Plc is one of

the leading producers of carbonated

beverages in Nigeria. The company obtained the seven-up,

Pepsi-cola, Mirinda, mountain dew andTeem franchise.



Seven-up Bottling company has several

departments which includes:

Water treatment plant

Syrup room

Carbon dioxide plant

Production line

Central laboratory

Pet laboratory



Water is a major raw material in softdrink and makes up to 80% therefore,its treatment for operations cannot beover-emphasized.

Water treatment forms an integraloperation in order to produce highquality products with appreciableshelf life.



The syrup room is the heart of the soft drink

production. It is where raw syrup, simple

syrup and final syrup are produced.Brix Determination ;

Determine the brix of distilled water as a

way of zeroing the refractometer The syrup is placed on the surface of the

refractometer and the brix is determined.



This section deals with the production of

CO2 gas.

The CO2 gas is responsible for the tingletaste of the carbonated beverage.

It also serves as preservative.



The final carbonated beverages areproduced in the production line.

Bottling operation involves :

Collection of empty unwashed bottlesfrom the ware house

Washing of the dirty bottles

Preparation of beverages on the lines

Filling of beverages in the washedbottles

Crowning of filled bottles



The tests are as follows:

Chlorine test: 3 drops of phenolphthalein

is added into selected bottle samples. Ifthe solution turns orange or yellow, it

indicates the presence of chlorine in thebottle. This is not desirable. The

production must be stopped for

correction.



In the central laboratory, quality program is

observed and it is in 3 dimensions:

Food safety(safety of products andconsumer·s right·s protection)

Plant quality(products are manufactured

to quality standards) Trade quality(consumer·s perception)



Food safety includes carrying out

Independent trade analysis.

This includes :

labelling of samples

carbonation

Degassing titratable acidity

inverted brix and brix determination

liquid content.



Labelling includes :writing down the

production code , the bottle size, the

bottle appearance, and the crowncrimpage and the crown condition.

Carbonation: carbo QC is turned on

Calibration is done using a blank The sample is rocked 15 times, placed in

Carbo QC and the amount of CO2 is

read.



Degassing : 200ml of the sample is put in

a round bottom flask and the air

compressor is set to about 70psi.The air hose is put in the flask which

contains the flavour.

The time is set on the stop clock depending on the time required and the

sample is degassed.



Titrable acidity: 100ml of degassed sample ismeasured into a beaker

2ml of TPC is added to Pepsi alone

A spin-bar is dropped in the center of the beaker and placed on the magnetic stirrer.

The pH electrode is placed in the beaker

Titration is done with 0.1N NaOH

Inverted brix and: Inverted brix measures theglucose and fructose content in drinks which areproducts of hydrolysis of sucrose.

.



Measure 30ml of sample into boiling tube

Add 2 drops of HCL to each tube(HCL is not

added to Pepsi samples)Place tubes in water and boil for 45 minutes

Allow tubes to cool

Determine the brix of distilled water Rinse densitometer with samples

Inject sample into densitometer anddetermine the brix.



Seven-up bottling company ensures

that all consumers are provided with

products that are safe for humanconsumption
