  • Lab 6. Who Cut the Cheese? Acid-Base Properties of Milk
    Lab 6. Who Cut the Cheese? Acid-Base Properties of Milk How do I make cheese? Should I drink milk if I have an upset stomach? Can I make milk from cheese? Objectives (i) apply equilibrium principles to acid-base and solubility reactions (ii) separate the protein from milk and make cheese (iii) determine the pI and buffer capacity of milk Introduction According to the milk industry, “Milk does a body good”. Milk is one of the more complete foods that are found in nature. Whole milk contains vitamins (mainly thiamine, riboflavin, pantothenic acid, and vitamins A, D, and K), minerals (calcium, potassium, sodium, phosphorus, and trace metals), proteins (which include all the essential amino acids), carbohydrates (mainly lactose), and lipids (fats). The only important elements that milk does not have are iron and Vitamin C. The fat in non-skim milk is dispersed in milk as very small (5-10 microns in diameter) globules. Since the fat is so finely dispersed, it is digested more easily than fat from any other source. Milk is homogenized by forcing it through a small hole. This breaks up the fat globules into smaller ones about 1- 2 microns in diameter. The fat in homogenized milk will not separate. There are three kinds of proteins in milk: caseins, lactalbumins, and lactoglobulins. Casein is the most abundant protein in milk and exists in milk as the calcium salt, calcium caseinate, which forms a micelle. Lactalbumins are the second most abundant protein in milk and are denatured and coagulated by heat. Lactose is the principal carbohydrate in milk and is the only carbohydrate that mammals synthesize.

Committee on Graduate Work A~ vr;~,fi2 ~/ Co-Advisor Department~ev&JC~) · ead COLORADO STAT~!JNIV. UBRAR:ES ABSTRACT OF DISSERTATION Sensory and Functional Properties of Flavor Potentiators Flavor potentiators have been used for centuries to improve food flavor. However, neither the taste transduction mechanisms nor the behavior of flavor potentiators in food are fully understood. The objectives of this research were: 1. To determine the relationship between salivary glutamate and perception ofMSG and NaCl; 2. To characterize the time-intensity profiles (TI) of flavor potentiators; and, 3. To determine the effects of heat treatment and pH on levels ofL-glutamic acid in simple food systems. The first study consisted of collecting whole mouth saliva and determining thresholds to and perceived intensities ofMSG and NaCl. A preliminary experiment indicated that perception ofMSG may be influenced by salivary glutamate, gender, and ethnicity. The principal study with 60 subjects found no effect of ethnicity or gender on salivary glutamate or sodium levels. Female Asians had higher salivary sodium and rated the lower concentrations ofNaCl as more intense.

Box 1346 Ann Arbor, Ml 48106-1346 ' , Abstract Part I of the thesis deals with the formation and transamination of Schiff's base complexes of copper, pyridoxal phosphate and glutamate, and the transamination of reaction mixtures containing copper, pyridoxamine phosphate and a-ketoglutaric acid. The formation of the complex of copper,, pyridoxal phosphate and glutamate was found to be first order in both pyridoxal phosphate and glutamate and zero order in copper. Spectrophotometric studies showed isosbestiv points when reaction mixtures were scanned over the range 20,000-35f000 cm*"^ indicating that only one step is involved. At high concentrations of copper (^l6 mî-l) the initial reaction rate became slig h tly dependent upon the copper concentration, and the i n i t i a l optical density of the reaction mixture departed from that of pyridoxal phosphate.
