The size of the scale insect is 21 to the inch according to The Universities of Minnesota, Florida, UCLA Davies, Clemson, etc. Therefore an insect of 21 to the inch will not pass through a mesh of 70 to the inch.
Don't use the "Positive-shmatah" for filtering juice which is viscous, use the 70-80 mesh sifter only.
You should use the right tools for the job, a pliers or wrench may turn the screw (and damage it.) Note: The shmatah is for only for non-viscous liquid, i.e. water
All Orange Juice requires filtering through a 70-80 mesh filter.
Canned Pineapple packed in it's own juice may have insects or parts of insects.
The 70-80 mesh filter should be used for that as well.
The pineapple should be rinsed.
Another factor Greek prices are dropping is the growing concern over EEVO adulteration. This year, some Greek olive oil companies began importing repaso olive oil from Spain. Repaso is the process of passing the olive paste waste through the centrifuge a second time with hot water.
This way, the remainder of olive oil left behind in the olive paste is extracted. Some Greek producers mix it with EEVO; something that Italian producers have been accused of for years. Greek legislation prohibits mills to produce repaso oil.
The “Hellenization” of Spanish repaso olive oil was suspected to be the main reason prices of Greek EVOO have dropped, according to Olive Oil Times. The Greek government has pledged to strengthen controls to protect the quality of local olive oil.
