Hepatitis A or B -
Risks of infection
|
No |
Possible |
Through cleaning-up of 3-tank
and 4-function dishwasher, the
dishes are cleaned under 85°C
hot water for 2 minutes and
disinfected through 110°C
infrared for 1.5 hours. So the
risk of infection won’t exist. |
|
Safety of utensils |
1. the surface is wax-treated; toxic
elements will be liberated under over
65°C temperature
condition.
2. plastic membrane is smeared on the
surface. |
Using melamine utensils mostly; fragile;
pores are on
the surface, so hard to be cleaned.
|
Mostly made of anti-high
temperature PP material or
ceramics. Few pore is on the
surface, the rate of plate
damage is lower. |

Comparison with appearance
and material |
*Merit:
a.
lighter
*Defects:
a. wax on the surface
b. might cause damage to
environment
c. plenty of residual of blanching
water occurs after paper
utensils have been
produced.
d. cannot bear heavy food or
dish because of its light
material.
|
*Merit:
a. looks elegant.
b. won’t be softened.
*Defects:
a. dye contains lead, it might
cause damage to health for
long-tern use. (except
white
plates)
b. heavier
|
*Merit:
a. lighter
b. cheaper than ceramic
*Defects:
a. fragile
b. might cause damage to
environment, not
recyclable,
cannot be dissolved even
after
hundreds of years.
c. porcelain enamel on the
surface might collapse
after
long-term use so residual
won’t be easily washed
away from the tiny holes. |
*Merit:
a. lighter
b. wasted plates are recyclable.
There are recycling
centers for
purchasing them.
Re-used
material can be
re-produced
as sub-degree
plastic.
c. cheaper than ceramic.
d. color won’t fade, neither
will dye.
e. can be used in microwave,
high-temperature resistant
f. hard to be broken, more
durable.
g. due to few pores, easy to
becleaned.
*Defects:
Price is higher than paper
utensils’. |
|
Rate of losses |
1st.
Paper utensils are wasted just
once. The reason is paper bowls
or plates cannot be washed. And
trees grow for decades, the value
vanishes only in few minutes.
That not only wastes social cost,
but causes damage to
environment. |
2nd.
Ceramic utensils are fragile, not
recyclable, and expensive so not
suitable for factory restaurants. |
3rd.
Melamine plates are cast from
mold of die casting. The material
feature is – cannot bear great
collision. Thus when the dishes
are stacked for cleaning, losses of
plates are inevitable indeed. |
4th.
PP material is more durable,
resistant to collision, so the
losses are much lower. |
|
Cost |
4th.
It’s easy to make thin utensils,
thus the cost is low. |
1st.
Producing process is
complicated, so the cost is
higher. |
3rd.
The material has been used for a
long time, and easy to get the
source; composition is not
complicated like pp material. |
2nd.
Innovative material – not
commonly used in Taiwan, so
the cost is higher. |
|
Note |
Suitable for street vendors |
Suitable for family’s use or 5-
star hotel |
Suitable for general restaurants’
use |
Suitable for family, factory, or
school restaurants’ use.
Our company can offer this kind
of utensils.

Sensory
Inspection:
1. To check if any
residual or deposits leaves on the utensils by visual inspection.
2. To check if
lime-scale deposits or a white haze appears on the surface of
glassware or utensils by visual inspection. If ‘cloudy’ or ‘milky’
conditions appear, it means utensils are still unclean.
|
Technological Inspection on Residual :
1. Amylum-Inspection –
inspected by Iodine, if the color goes
blue,
it means starch still remains on the utensils.
2. Adipose-Inspection –
inspect by Sudan IV liquid, if the color goes
red,
it means Adipose still remains.
3. Protein-Inspection –
inspect by Ninhydrin liquid, if the color goes
purple,
it means protein still remains. |
