Answer 10

yes
gas chromatography
conductivity measurements ( salt concentrations ) and refractometers (sugar) and ph measures

Question 11

main flavour measurments

Answer 11

taste panels

Question 12

what is nutritional value and example of

Answer 12

hidden quality attribute

Question 13

what is accelerated storage trails used for
