[問 2]
Examples 1 to 5 and Comparative Examples 1 and 2
Dry spaghetti was boiled until the yield reached 230%, and immersed into an aqueous
solution containing 0.8% by weight of fermented lactic acid and 0.8% by weight ofgluconic acid to obtain boiled spaghetti with low pH.

To 100 g of thus-obtained low-pH

boiled spaghetti, 5 g of olive oil was added and mixed fully which oil contained 1 g of analkali agent with an average particle diameter shown in Table 2.

After that, 10panelists evaluated the spaghetti about [acid taste and acid odor] and [foreign taste andforeign odor] in accordance with evaluation standards shown in Table 1. The results ofthe sensory evaluation are shown in Table 2. In the evaluation, the content of thealkali agent in the olive oil was equal to the acid equivalent of the low-pH boiled
spaghetti.

[問 3][0001]The back plate of an organic EL has been conventionally produced by the following
procedures: for the purpose of obtaining a desired projected profile on soda glass, which
is a main material, a photosensitive resist film is fixed on the glass; the resist film isexposed to UV light (ultraviolet light) via a glass mask; the resist film is developed withan organic solvent and an alkaline developer such as sodium carbonate decahydrate toform a desired pattern; after that, inorganic powder and high-pressure air are blasted
against the resist film with a sand blasting apparatus, where the resist film is anegative photosensitive film, and the area of the film exposed to UV light is cured andnot removed by the inorganic powder blasted with the sand blasting apparatus to allow
selective grinding of the glass between the resist-covered glass surface and glass surface
where the resist film is removed in the developing procedure. These procedures aredisclosed, for example, in Patent Document 1.
[0003]
Because inorganic powder is projected through the thin nozzle of a sand blasting
apparatus in the sand blasting process, grinding large area with the sand blastingprocess can result in varieties in ground depths and a ground surface with roughsurface roughness depending on the particle diameter of the inorganic powder.
Therefore, by using the sand blasting process, it is difficult to achieve precise ground
depths and fine surface roughness of a ground surface.
[0004]
To overcome the problem, the ground surface is conventionally planarized by etchingtreatment.

This requires additional procedures to increase processing costs.
