Description
• Producers  and  processors  are  primarily  concerned  with  production  aspects   • All  sectors  of  the  production  chain  up  to  the  consumer  are  involved  in  marketing  and  selling   their  products   • The  processing  sector  is  concerned  with  producing  value-­‐added  products  to  sell  as   ingredient  for  other  processors,  or  as  finished  products  destined  for  the  retail  or  food   service  markets.  Sale  of  products  is  often  mediated  by  distributors.   • Trade  and  consumer  associations  act  as  advocates  for  interests  of  particular  sectors     What  is  the  economic  and  social  impact  of  the  agri-­‐food  industry?   In  many  countries,  the  agricultural  and  food  industries  are  large  contributors  to  the  gross   domestic  product,  national  tax  revenues,  and  employment.   Many  industries  (not  just  food  industries)  have  looked  towards  foreign  markets  for  sales   and  procurement  of  products  and  services  in  a  trend  commonly  referred  to  as  ‘globalization’     Example  of  a  global  trading  block  is:  North  American  Free  Trade  Agreement  (NAFTA)-­‐   Canada,  United  States  and  Mexico   Global  Food  Issues:   Various  food  scientists  from  academic,  government,  and  industry  have  devoted  part  or  all  of   their  careers  to  assisting  foreign  countries  in  matters  related  to  prevention  of  food-­‐borne   illness,  sustainable  agricultural  practices,  marketing  of  commodities,  food  security,  and   prevention  of  malnutrition.     Food  security:  assured  access  to  enough  food  at  all  times  for  an  active  and  healthy  life.     Food  insecurity:  occurs  whenever  the  availability  of  nutritionally  adequate  and  safe  food  or   the  ability  of  acquire  acceptable  foods  in  socially  acceptable  ways,  is  limited  or  uncertain   Hunger:  uneasy  or  painful  sensation  caused  by  recurrent  or  involuntary  lack  of  food  and  is  a   potential,  although  not  necessary  consequence  of  food  insecurity.  Over  time,  hunger  may   result  in  malnutrition.     Chapter  Two  (pg  21-­‐55)   Food  composition:  refers  to  the  substances  or  component  found  in  a  beverage  or  food   Key  Nutrients  that  compose  foods:   -­‐ larger  molecules:  protein,  fat  (lipid),  and  carbohydrates  (starch,  sugars,  and  fibre)   -­‐ smaller  molecules:  water,  vitamins,  minerals,  and  phytochemicals     Beverage-­‐  a  drinkable  liquid,  consumed  for  a  variety  of  reasons  including     1) thirst  quenching   2) stimulant  effect   3) alcoholic  content
