|||| |||| |||| |||| |||| |||| ||||




answers ||||




Which amino acids must be present in a parenteral solution?
|||| |||| |||| |||| |||| |||| |||| |||| ||||




a. valine, leucine, glycine, alanine |||| |||| ||||




b. tryptophan, phenylalanine, threonine, isoleucine || || ||




c. phenylalanine, methionine, arginine, tyrosine || |||| ||||




d. lysine, glutamic acid, alanine, glycine - correct answers✔✔ b. tryptophan,
|||| |||| |||| |||| |||| |||| |||| |||| ||||




phenylalanine, threonine, isoleucine
|||| |||| ||||




A parenteral solution requires adequate supplementation of all essential amino acids.
|||| |||| |||| |||| |||| |||| |||| ||| |||| ||||




Essential amino acids = those that cannot be produced by the body. Mneumonic: PVT TIM HLL:
|||| |||| |||| |||| |||| |||| |||| |||| |||| |||| |||| |||| |||| |||| ||||




phenylaline, valine, tryptophan, threonine, isoleucine, methionine, histadine, lysine, leucine.
|||| |||| |||| |||| |||| |||| |||| |||| ||||




Last two L's are ketogenic amino acids (lysine and leucine). Mneumonic: Tim LIVs for this
|||| |||| |||| |||| |||| |||| |||| |||| |||| |||| |||| |||| |||| ||||




BRANCH of the military- branched amino acids are leucine, isoleucine, and valine. Note:
|||| |||| |||| |||| |||| |||| |||| |||| |||| |||| |||| |||| ||||




arganine and glutamine are conditionally essential.
|||| |||| |||| |||| |||| ||||




When you check overrun, you are checking
|||| |||| |||| |||| |||| ||||




a. excess stock in the storeroom |||| |||| |||| ||||




b. surplus soap and rinse aids used in the dishmachine |||| |||| |||| |||| |||| |||| |||| ||||




c. the weight of ice cream |||| |||| |||| ||||




d. Total costs of unexpected meals served - correct answers✔✔ c. the weight of the ice cream
|||| |||| |||| |||| |||| |||| |||| |||| |||| |||| |||| |||| |||| |||| ||||




Overrun is the increase in volume from freezing and whipping which is used to determine the weight.
|||| |||| |||| |||| |||| |||| |||| |||| |||| |||| |||| |||| |||| |||| |||| ||||




In ice cream, overrun should be 70-80%
|||| |||| |||| |||| |||| |||| ||||




What is the process by which the water content of a vegetable is replaced by a concentrated salt
|||| |||| |||| |||| |||| |||| |||| |||| |||| |||| |||| |||| |||| |||| |||| |||| ||||




solution?
||||




a. gelling

b. osmosis

,c. diffusion

d. retro-gradation - correct answers✔✔ c. diffusion ||| |||| |||| |||| ||||




Diffusion is when particles move from higher to lower concentration. In this example, the
|||| |||| |||| |||| |||| |||| |||| |||| |||| |||| |||| |||| ||||




concentrated salt (higher concentration) moves towards the area of lower concentration (the
|||| |||| |||| |||| |||| |||| |||| |||| |||| |||| |||| ||||




water in the vegetable).
|||| |||| |||| ||||




Osmosis is when fluid moves from less to more concentrated side of memebrane
|||| |||| |||| |||| |||| |||| |||| |||| |||| |||| |||| ||||




(semi-permeable membrane).
|||| ||||




Which recipe ingredient should be adjusted if a cake has a crunchy crust and compact moist texture?
|||| |||| |||| |||| |||| |||| |||| |||| |||| |||| |||| |||| |||| |||| |||| ||||




a. milk

b. flour

c. sugar

d. baking powder - correct answers✔✔ c. sugar |||| |||| |||| |||| |||| ||||




Sugar provides tenderness (as hydrogroscopic) and flavor in baking. When too much is added,
|||| |||| |||| |||| |||| |||| |||| |||| |||| |||| |||| |||| ||||




this results in falling in the center and coarse texture. Not enough sugar causes poor volume.
|||| |||| |||| |||| |||| |||| |||| |||| |||| |||| |||| |||| |||| |||| |||| ||||




Why do egg whites beat more easily at room temperature?
|||| |||| |||| |||| |||| |||| |||| |||| ||||




a. the pH is increased
|||| |||| ||||




b. the protein is denatured
|||| |||| ||||




c. the surface tension is lower
|||| |||| |||| ||||




d. the surface tension is higher - correct answers✔✔ c. the surface tension is lower
|||| |||| |||| |||| |||| |||| |||| |||| |||| |||| |||| |||| ||||




Which pigment does not change color in an acid or an alkaline solution?
|||| |||| |||| |||| |||| |||| |||| |||| |||| |||| |||| ||||




a. anthocyanin

,b. chlorophyll

c. carotenoid

d. flavones - correct answers✔✔ c. carotenoid |||| |||| |||| |||| ||||




Carotenoids have little to no change when exposed to acid or base. |||| |||| |||| |||| |||| |||| |||| |||| |||| |||| ||||




Anthocyanin is a type of flavone and turns bright red in acid, blue in base. Chlorophyll turns olive |||| |||| |||| |||| |||| |||| |||| |||| |||| |||| |||| |||| |||| |||| |||| |||| ||||




green in acid (pheophytin), and bright green in base (chlorophyllin).
|||| |||| |||| |||| |||| |||| |||| |||| |||| ||||




The end products of cellular oxidation are:
|||| |||| |||| |||| |||| ||||




a. water, carbon dioxide, energy |||| |||| ||||




b. carbon, hydrogen, nitrogen |||| ||||




c. indigestible fiber, nitrogen || ||||




d. monosaccharides, amino acids, energy - correct answers✔✔ a. water, carbon dioxide, energy |||| |||| |||| |||| |||| |||| |||| |||| |||| |||| ||||




Cellular respiration is an oxidative process whereby an electron donor is oxidized and oxygen is
|||| |||| |||| |||| |||| |||| |||| |||| |||| |||| |||| |||| |||| ||||




reduced to produce carbon dioxide, water, and energy.
|||| |||| |||| |||| |||| |||| |||| ||||




Carbohydrates listed in order of decreasing sweetness are: |||| |||| ||| |||| |||| |||| ||||




a. fructose, glucose, sucrose, sorbitol |||| |||| ||||




b. sucrose, glucose, fructose, sorbitol ||| ||| ||||




c. fructose, sucrose, glucose, sorbitol || ||| ||||




d. sorbitol, fructose, sucrose, glucose - correct answers✔✔ c. fructose, sucrose, glucose, sorbitol
|||| |||| |||| |||| |||| |||| |||| |||| |||| |||| ||||




The order of carbohydrates from sweetest to least sweet is as follows: fructose, invert sugar,
|||| |||| |||| |||| |||| |||| |||| |||| |||| |||| |||| |||| |||| ||||




sucrose, glucose, sorbitol, mannitol, galactose, maltose, lactose. Mainly remember that
|||| |||| |||| |||| |||| |||| |||| |||| |||| ||||




fructose is the sweetest, sucrose is sweeter than glucose, and glucose is sweeter than sorbitol
| | | | |||| |||| |||| |||| |||| |||| |||| |||| |||| |||| |||| |||| |||| ||||




and mannitol.
|||| ||||

, The flakiness of pie crust depends on:
|||| |||| |||| |||| |||| ||||




a. type of fat |||| ||||




b. oxidation of fat |||| ||||




c. temperature of the fat |||| |||| ||||




d. oven temperature - correct answers✔✔ a. type of fat |||| |||| |||| |||| |||| |||| |||| ||||




Flakiness is promote by leaving fat in coarse particles. Fat in pieces melts and flows, leaving a
|||| |||| |||| |||| |||| |||| |||| |||| |||| |||| |||| |||| |||| |||| |||| ||||




hole where steam colleccts and pushes upward against the upper surface of the resulting cell.
|||| |||| |||| |||| |||| |||| |||| |||| |||| |||| |||| |||| |||| |||| ||||




The cell is locked into that extended position, resulting in a flaky crust
|||| |||| |||| |||| |||| |||| |||| |||| |||| |||| |||| |||| ||||




A 10 can holds how many cups of product?
|||| |||| |||| |||| |||| |||| |||| ||||




a. 10

b. 13

c. 12

d. 5 - correct answers✔✔ b. 13
|||| |||| |||| |||| ||||




10 can = 6 cans per case, 6 lb 9 oz, 13 cups, 20-25 servings (it is also considered 3 quarts but dont
|||| |||| |||| |||| |||| |||| |||| |||| |||| |||| |||| |||| |||| |||| |||| |||| |||| |||| |||| |||| |||| ||||




get confused about cups because 3 quarts = 12 cups, most sources indicate 13 cups so just use
|||| |||| |||| |||| |||| |||| |||| |||| |||| |||| |||| |||| |||| |||| |||| |||| |||| ||||




that)
||||




If the sole source of protein is gelatin, growth is inhibited because:
|||| |||| |||| |||| |||| |||| |||| |||| |||| |||| ||||




a. gelatin has no tryptophan and is low in methionine and lysine |||| |||| |||| |||| |||| |||| |||| |||| |||| ||||




b. gelatin has no methionine and is low in tryptophan |||| |||| |||| |||| |||| |||| |||| ||||




c. gelatin has no lysine or methionine, and is low in tryptophan |||| |||| |||| |||| |||| |||| |||| |||| |||| ||||




d. gelatin has no arginine - correct answers✔✔ a. gelatin has no tryptophan and is low in
|||| |||| |||| |||| |||| |||| |||| |||| |||| |||| |||| |||| |||| |||| ||||
