|157. Organisms, which utilize simple inorganic compounds, are termed as
An autotroph is an organism that can produce its own food using light, water, carbon dioxide, or other
chemicals.Autotrophs are a vital part of the food chains of all ecosystems.They serves as primary producers
in a food chain, such as plants on land or algae in water.Autotrophs reduces carbon dioxide (add hydrogen
to it) to make organic compounds.
Autotroph can be phototrophs or lithotrophs (chemoautotrophs). Phototrophs use light as an energy source,

|167. What is the TSS of fruit syrup?
Total Soluble Solid (TSS) is one of the more important quality factors for most fruit juices. TSS of fruit represent
various chemical substances present in it in soluble form. The amount of TSS present in the fruit sample is also
considered to be a reliable index in judging its maturity. Fruit syrup may be clear or opaque, but it must contain
ornage juice content not less than 25 % and water soluble substance at least 65% with low acidity.

d) Williams Apert
Basic principle of Canning process was developed and commercialized by Nicholas Appert, a French
confectioner and distiller in 1810. Nicholas Appert, French inventor of airtight food preservation is also
known as ‘Father of Canning’.
Canning is the process in which foods are placed in jars or cans and heated to a temperature that destroys
microorganisms and inactivates enzymes. This heating and later cooling forms a vacuum seal. The vacuum
seal prevents other microorganisms from recontaminating the food within the jar or can.
