  • Producer prices of raw milk include following elements: a basic price, payment according to fat content, payment according to bacteriological quality and somatic cell count. The quality of raw milk has increased since last change of payment system according somatic cell count. But last change of payment system according to fat content is not effective. It is necessary to widen the range of equal price by fat content. Also it is necessary to include payment according to protein content.

  • This study was conducted to investigate the effect of increasing dietary fat on plasma lipoprotein in young Korean women. During the three weeks of experimental periods, 8 healthy college women consumed a regular diet, a medium fat diet and a high fat diet for one week, consecutively. The percentages of fat from energy intake in the subjects on the regular, medium, and high fat diets were 20, 29 and 38%, respectively. Our data showed that the dietary intakes of fat and cholesterol had an influence on the plasma lipoprotein. The medium fat diet enhanced the blood glucose concentration and the plasma HDL, and the high fat diet resulted in increases in the blood glucose concentration and the plasma LDL as well as HDL. Also the type of diets led to changes in the composition of lipoprotein. When on the medium fat diet, HDL and LDL had higher phospholipid content. On the high fat diet, LDL had higher phospholipid, cholesterol and triglyceride contents, and HDL included higher cholesterol content.

  • Milk yield and its composition is governed by level of nutrition and the composition of diet. Higher concentrate input improves milk yield, whereas its input at moderate levels improves yield of milk fat. High level of dietary protein improves dry matter intake and milk production, however, CP content above 14% has less advantage. Milk yield is enhanced by the feeding of cottonseed and soyabean meal, whereas milk fat increases by the supplementation of cottonseed. Dietary fat increases energy intake, production of milk and milk fat. Quality and quantity of feeds consumed affect fermentation patterns in rumen. Among the rumen metabolites, volatile fatty acids (VFA) content and propionate proportion have been related positively with milk yield, whereas proportion of acetate and butyrate have been related positively with milk fat content. Dietary carbohydrates through the source of sugar, starch, roughage and fibre affect VFA concentration in rumen. Therefore, concentration of volatile fatty acids could be altered to the advantage of consumer through judicious manipulation of diet.

  • This work was carried out to investigate the relation between the fat content and the metamorphosis as the silkworms grew. The results obtained are as follows: 1. The content, of which the dry matter had been 24% at the stage of newly hatched silkworms, were gradually decreased by feeding on, but suddenly increased to the 28.5% at the mature stage. Those decreased slightly from pupation to just before the moths, and again increased to the 32% of the dry matter when became the moths. 2. The content, of which the fat had been 16.2%, however, decreased as the silkworms grew. The fat content increased little by little from the first feeding to the vigorous eating, but the matured worm contained only 15.7% of the fat. 3. The fat content of both male and female showed an increase to 23.5% and 35.7%, respectively. After that, the contents of it decreased to 12% and suddenly increased to 26% just before the moth in female. In male the content of fat showed a slight increase till before the moth, and after moth became, it were 42.5%.

  • The effects of reducing pork fat levels from 20% to 15% or 10% by partially substituting pork back fat with wheat sprout fiber in reduced-fat chicken patties were investigated. Approximate composition, energy value, pH, color, cooking loss, reduction in diameter, reduction in thickness, shear force, and sensory properties were determined. Moisture content, ash contents, yellowness of uncooked and cooked reduced-fat chicken patties with wheat sprout were higher than those in the control, while displaying fat content, calorie content, and pH of uncooked and cooked lower in reduced-fat chicken patties than in the control. Cooking loss, reduction in diameter, and reduction in thickness were the highest in the reduced-fat chicken patties with 10% fat level. Cooking loss, reduction in diameter, and reduction in thickness were decreased when fat levels and wheat sprout levels were increased. Control samples without wheat sprout dietary fiber had significantly (p<0.05) higher color and flavor scores compared to reduced-fat chicken patties containing wheat sprout dietary fiber. The overall acceptability of the control and treatment with 15% fat and 2% wheat sprout dietary fiber (T3) was the highest. Therefore, 15% fat level in reduced-fat chicken patties with the addition of 2% wheat sprout dietary fiber can be used to improve the quality and sensory characteristics of regular-fat chicken patties containing 20% fat level.

  • Oral supplementation with potassium permanganate (30, 50 and 100 $\mu\textrm{g}$) to fifth instar larvae of the ${CSR_2}{\times}{CSR_4}$ race of the silkworm, B. mori resulted in a significant increase in the glycogen content of the fat body and haemolymph trehalose. The protein content of the fat body is also significantly increased in all the potassium permanganate treated groups where as that of the haemolymph is significantly increased only in the 30 ${\mu}g4 fed group. The total lipids content of the fat body increased significantly in all the potassium permanganate treated groups. This indicates that the potassium permanganate may stimulate metabolic activity, there by influencing the biochemical contents in the fat body and haemolymph of the silkworm, B. mori.

  • Breads and cookies made with conventional or low-trans fat(margarine and shortening) were analyzed by determining their trans fat content, textural properties and color values after production. The trans fatty acids content in conventional margarine was three times higher than that of low-trans margarine. Moreover, the content of trans fatty acids in the conventional shortening was 49 times higher than that of low-trans shortening. The trans fatty acid contents of cookies and breads made with low-trans fat, can be reduced more than 2 to 75 times compared to cookies and breads made with conventional fat. In the produced cookies and breads, the color values and textural properties(hardness, springiness, cohesiveness, gumminess and chewiness) did not differ significantly when the conventional fat or low-trans fat was used.

  • Comminuted sausages with reduced fat (25-0%) and increased moisture (19-44%) combinations were manufactured, and their chemical composition, and physico-chemical, textural and sensory properties were determined for the selection of the most palatable sausage treatment. The moisture and fat contents of the comminuted sausages varied from 55-79% and 26.4-2.14%, respectively, whereas, the protein content was relatively constant at 13.5-14.5%. Expressible moisture (EM, %) decreased with increased fat addition, and the high-fat control sausage (~25% fat) had lower EM than those with lower than 15% fat addition. Increased fat level also increased Hunter L values (lightness) of sausage samples taken from the core, and differences in lightness were observed between 15 and 25% fat level at the initial mixture. Sausages without fat addition had different textural characteristics from high-fat control sausages in most texture profile analysis (TPA) values. However, no differences in TPA values were observed among treatments with added fat (<25%) in the formulation. Results of the sensory evaluation showed that the most appropriate fat content of comminuted sausages to have better sensory properties ranged from 15-20% of added fat at the initial mixture. These results also indicated that decreased fat and increased moisture contents produce sausages with higher EM and lower lightness. Comminuted sausages without fat addition had different textural characteristics from the high-fat control.

  • Buffalo meat patties with two fat levels, F1 (15% added fat) and F2 (5% added fat and 3% tapioca starch), were cooked in a pre-heated hot air oven (HO) at $175{\pm}2^{\circ}C$ for 15 min, in a microwave oven (MO) for 70 sec and by pressure cooking (PC) at 15 psi pressure for 10 min. and compared for physico-chemical, processing, sensory and microbiological quality attributes. F2 had significantly (p<0.05) higher value for the moisture and moisture protein ratio than F1. However, MO and PC patties had significantly (p<0.05) higher moisture content than HO-cooked buffalo meat patties irrespective of fat content. Highest fat percentage was in MO patties while the minimum was in PC patties. Moisture and fat retention and cooking yield were highest in MO patties irrespective of added fat content in the formulation. Cooking yield and dimensional parameters were better maintained in F2 than F1. Sensory scores viz. appearance and color, flavour, juiciness and texture for HO patties were better than other cooking methods. Sensory panelists rated overall acceptability of HO patties very good to excellent, whereas PC and MO patties were rated as good to very good irrespective of fat content. Microbiological quality was comparable in both groups irrespective of cooking methods used.

  • Concerns about meat quality, including chicken meat, for the human diet has led to many attempts to manipulate the carcass fat and increase the eating quality. For actual eating quality, the birds must be grown and finished in a manner that results in meat that are tender, succulent and of good flavor, as well as being free from any foreign taint, flavor or safety hazard. Tenderization treatment with high voltage(820V) electrical stimulation and prechill muscle tensioning would improve the tenderness of chicken meat. Proper programs for the withdrawal of feed and water require a team approach for maximizing yield of meat and minimizing carcass contamination. Also effding of supplemental levels of-tocopherol to poultry with vegetable or fish oils increases of desirable polyunsaturated fatty acid(PUFA) content and stablizes the meat against rancidity and fish off-flavors. The nutritional effects of varying dietary ingredients on broiler carcass fat content are also important. Increasing the levels of energy in the ration increases the carcass fat content, while increasing the proteing levels decreases carcass fat content. Supplement-tation of poultry diets with amino acids such as methionine, lysine, glycine and tryptophan as well as amino acid such as well as amino acid mixtures can reduce body fat deposition. Normal stress leads to chicken muscular damage resulting in reduced meat quality, but this can be controlled by preslaughter management practices. Feed manufactures can utilize ntilize nutrient modulation to control pale soft exudative(PSE)syndrome. Finally, the success in poultry meat production depends on the consistent achievement of carefully selected levels of quality. Quality assurance should be the wider function of incorporating quality into the production system and the combination of motivating quality into actions and operations.
