Assalamualaikum...

as for this week, i have to change with Shela where, I have to run
test for EMA product and Shela have to run test for EP product.
this is to make sure that we can do all test if they asked to.

so, this week started with 'dup dap dup dap' as i do not familiar with
all the test for EMA product as Shela does..
i have to refer to the note book all the time...

but, alhamdulillah,they guided me well...
for EMA product, the test involve are chemical test...
so, the titration is a must!!
for the first day, i have to test 17 samples for the acid value and
GPC...
from that practices, i've got more familiar with the acid value test
and GPC..
today, there is a training about GC from the supplier...
so, we have to attend the 'lecture' about GC for almost 3 hour!!
it's quite sleepy but we learned new things here...

but for me, en tajul's lecture for GC is better...haha..
they also provide us with the slide show for reference...
the 'mukadimah' from the supplier is quite frightening...
'u all mesti da familiar dgn GC ni, sbb utk "instrumentation", mesti
ade blaja psl chromatography ni utk 1 sem'
hah??

for ur information, all staff in QC do not have any basic in food and
mostly are graduated in chemical industry courses...
so, they are very expert in chemistry test and we can learn a lot from
them...
as the theory sessions ends, the supplier showed us how to run sample
using GC....
but there are some problem occur..
so, he will continue it tomorrow together with an exam!!
13 subjective questions!!
so, we have to study the slide show for tomorrow's exam...


i will end it here...
do pray for us!!
assalamualaikum....

on this week, there are 7 batches of cake emulsifier are being
produced by our factory.
for every batch, i have to check the sample for the first and last
parts of the batch...
so, if there are 7 batches of cake emulsifier, i have to produced 14
cakes for the analysis...
as the cake emulsifier are the EP product, I have to involve in the
analysis for the product...

for cake emulsifier, i have to prepare an analysis to check the SG
(specific gravity) for the emulsion.
as experienced in the bakery lab, i have to prepare the cake using the
cake emulsifier produced...
its a little bit tiring as in the bakery lab, there is no chair and
the time for the analysis is quite long....
the cake produced is the basic sponge cake without any flavour...
usually, the SG of the emulsion are within the range that the customer
wants...


during my analysis, there is one problem occur which is the SG is not
in the range...
although it have been repeated two times, the SG is still high...
so, the product has been rejected...
to overcome this problem,the product are being sent for re-sampling...
or, other ways is to re-label the products...


some of the emulsifier produced are from the same type but may have
different brand...
so, the product that have problems with its SG, will be sent to change
the label for the product with other brand that do not require low
SG...


i'm so sorry as there are not so many information that i can share
with all of u...
but, i will try my best to share as many as i could...
sharing is caring!!

Dayah MN has been told what we already do in Rikevita for this 3 weeks....
If Dayah MN more focused to do analysis for EP (emulsifier preparation)
products,
I was heavily involved for the EMA (emulsifier monoglycerate acetylated)
analysis products.
The samples for EMA products are usually in the powder, liquid or in the
semi liquid form.

I usually tasked to carry out analysis for the product in powder form.
Only 2 days before I was running a new analysis for the samples in the
liquid form.
Just like Dayah MN said, all the analysis just like chemistry experiments.
I have to deal with all sorts of dangerous chemicals.
So safety is a priority, I always wear gloves and mask when carrying out
analysis.
At the moment, Me and Dayah MN run a different analysis....
Dayah MN need to run for microbe test, fat analysis
(soxhlet),LOD (loss on drying), RI, and viscosity for EP products.
While, I need to run a test of IV (iodine value), AV(acid value), SV
(saponification value), OHV (hydroxyl value), and GPC (gas permeation
chromatography) for EMA product.


Let me share the function of all analysis that I have been done...

• AV = to test the num. of mg of KOH required to neutralised free fatty acid in 1 g sample.
• IV = to test the num. of g of iodine absorbed by 100 g of fat under test condition. it measures unsaturation of fat and oils.
• SV =  to test the num. of mg of KOH required to neutralised free fatty acid and saponify the esters in 1 g of sample.
• GPC = determine and quantitating the specific types of esters present in the product by separation using mobile phase and stationary phase. Usually, the types of peaks are show the present of TG (triglyceride), DE (diester), MG (monoglyceride), DG (diglyceride), FG (freeglyceride) in the sample.

Other that, I also need to check the particle size of the sample. This
analysis only done if have a request from customer.
Particle size analysis is a simple test. Just like a sieving test that we
had learned in class Pn. Norlia.
The function of this test to ensure that particle size is always in the
specific range to avoid the product become lumping when processed.
Ok....

I think enough for now. Me and Dayah MN will try our best to share our
experience in Rikevita.
just like Dayah said  "sharing is caring!!"........

sorry for the late reply as i just being invited by prof...

unlike other factory,rikevita does not produce finished food
product...

rikevita is producing the emulsifier for the cake,ice cream and other
products, one of the customer is apollo. 95% of the product produced are being exported to the other
countries..

so,i and shela are being placed in the QC lab..
we have to analysed the product before being released to the
customer...

some of the product are the same product but may have different brand
for different customer...

early in the morning, we have to follow the other staff to take sample
from the production area.
then,there is a meeting between the QC staff with the head of
department to divide the sample for each person to be tested...
usually, i have to run test for EP(emulsifier preparation) sample...
so, the test involve for the EP sample are microbe test, fat analysis
(soxhlet),LOD (loss on drying), RI, and viscosity...
for microbe test, the sample are being test for the presence of
coliform, yeast and mould and total plate count...
LOD is for moisture content test and RI is same as ashing...

on behalf of shela,usually, she has to run sample from EMA (emulsifier
monoglycerate acetylated)
so, the test involve are IV (iodine value), AV(acid value), SV
(saponification value) and OHV (hydroxyl value)....
All of these are as the same as chemistry experiements....
