Okinawan Awamori is produced by fermenting steamed indica rice with black mold, yeast, and water. Awamori-pressed lees is a by-product of the Awamori production process. Tofu lees is a by-product of the Tofu production process. This research consisted of two experiments conducted to elucidate whether or not dried Awamori-pressed lees and Tofu lees can be used as a mixed feed ingredient for raising female goats. In experiment 1, digestion trials were conducted to ascertain the nutritive values of dried Awamori-pressed lees and dried Tofu lees for goats. The digestible crude protein (DCP) and total digestible nutrients (TDN) contents of dried Awamori-pressed lees and Tofu lees were 22.5%, 22.5% (DCP), and 87.2%, 94.4% (TDN) respectively. In experiment 2, 18 female goats (Japanese Saanen${\times}$Nubian, three months old, body weight $15.4{\pm}0.53$ kg) were divided into three groups of six animals (control feed group (CFG), Awamori-pressed lees mixed feed group (AMFG), Tofu lees mixed feed group (TMFG)). The CFG control used feed containing 20% soybean meal as the main protein source, while the AMFG and TMFG treatments used feed mixed with 20% dried Awamori-pressed lees or dried Tofu lees. The groups were fed mixed feed (volume to provide 100 g/d increase in body weight) twice a day (10:00, 16:00). The klein grass hay and water was given ad libitum. The hay intake was measured at 08:00 and 16:00. Body weight and size measurements were taken once a month. At the end of the experiment, a blood sample was drawn from the jugular vein of each animal. The DCP and TDN intakes in AMFG and TMFG showed no significant difference to the CFG. Cumulative measurements of growth in body weight, withers height, chest depth, chest girth, and hip width over the 10 mo period in the AMFG and TMFG were similar to the CFG. By contrast, cumulative growth in body length and hip height in the AMFG and TMFG tended to be larger than the CFG. Cumulative growth in chest width in the AMFG was significantly larger (p<0.05) than the CFG. Blood parameter values were similar to those in normal goats reported by other scientists. The coats of the AMFG and TMFG animals looked shinier than the animals in the CFG. The results demonstrate that dried Awamori-pressed lees and Tofu lees can be used as a feed ingredient for the raising female goats.

Awamori is produced by fermenting steamed indica rice. Awamori-pressed lees is a by-product of the Awamori production process. Tofu lees is a by-product of the Tofu production process. Research was conducted to test if dried Awamori-pressed lees and Tofu lees can be used as a mixed feed ingredient for raising male goats. Eighteen male kids were divided into three groups of six animals (control feed group (CFG), Awamori-pressed lees mixed feed group (AMFG), Tofu lees mixed feed group (TMFG)). The CFG used feed containing 20% soybean meal as the main protein source, while the AMFG and TMFG used feed mixed with 20% dried Awamori-pressed lees or dried Tofu lees. The groups were fed mixed feed (volume to provide 100 g/d increase in body weight) and alfalfa hay cubes (2.0 kg/d) twice a day (10:00, 16:00). Klein grass hay and water was given ad libitum. Hay intake was measured at 10:00 and 16:00. Body weight and size measurements were taken once a month. At the end of the experiment, a blood sample was drawn from the jugular vein of each animal and the carcass characteristics, the physical and chemical characteristics of loin were analyzed. DCP and TDN intakes in AMFG and TMFG showed no significant difference to the CFG. Cumulative measurements of growth in body weight and size over the 10 mo period in the AMFG and TMFG were similar to the CFG. Blood parameter values were similar to those in normal goats. Dressing carcass weight and percentages, and total weight of meat in the AMFG were similar to that in the CFG, but smaller in the TMFG. The compressed meat juice ratio was higher in both the TMFG and AMFG than the CFG. While the fat in corn, Awamori-pressed lees, and Tofu lees contains more than 50% linoleic acid, the loin fat in both the AMFG and TMFG was very low in linoleic acid due to the increase in the content of oleic acid, stearic acid, and palmitic acid. This indicates that feeding on AMF and TMF does not inhibit hydrogenation by ruminal microorganisms. As in the CFG, the total essential and non-essential amino acids in the loin of the AMFG and TMFG were well balanced. Compared to the CFG, the AMFG and TMFG were high in taurine and carnosine. The results indicate dried Awamori-pressed lees and Tofu lees can be used as a feed ingredient for raising male goats.

Makgeolli lees is a jigaemi by product produced by makgeolli brew processing. Jigaemi has high fiber content and therefore can potentially be used in the development of foods rich in dietary fiber. The effects of makgeolli lees fibers on the composition and physico-chemical properties of chicken emulsion systems were studied. The moisture and ash contents, yellowness, and viscosity of chicken meat emulsion systems with makgeolli lees fiber were all higher than those of control. Moreover, chicken batters supplemented with makgeolli lees fiber were characterized by lower cooking loss and better emulsion stability. Chicken emulsion systems with makgeolli lees fiber also had improved emulsion stability and emulsion viscosity, and the best results were obtained with meat batter containing 2% makgeolli lees fiber.

The objective of this study was to assess the physicochemical characteristics of morning rolls containing various levels (0, 2, and 4%) of Makgeolli lees extract powder, which has nutritional and health effects. The results demonstrated that pH, moisture content, volume, weight, and baking loss rate of morning rolls were not significantly different among the groups. In the morning rolls with 4% Makgeolli lees extract powder, the Hunter's color 'a' (redness), but not L (lightness) or b (yellowness), was significantly higher than that in the other two groups. After estimating the texture quality of morning rolls, hardness, chewiness, and gumminess decreased significantly with added Makgeolli lees extract powder, but springiness was not significantly different. The results of the sensory test showed that appearance and texture increased as more Makgeolli lees extract powder was added, and that the overall acceptability score and air cell uniformity score for 2% and 4% Makgeolli lees extract powder morning rolls were significantly higher than those of controls. These results indicate that the texture and sensitivity of morning rolls can be increased by adding Makgeolli lees extract powder without affecting the overall quality.

The technological effects of Makgeolli lees fiber (0, 0.5, 1.0, 2.0, and 4.0%) on chicken salt-soluble breast meat proteins in a model system on proximate composition, physicochemical properties, and textural properties were investigated. Makgeolli lees fiber was obtained from Makgeolli brew processing, and the by-products showed good dietary fiber. The moisture and ash contents, water holding capacity, redness, yellowness, hardness, and apparent viscosity of chicken salt-soluble meat protein heat-induced gel systems with Makgeolli lees fiber were all higher than the control without Makgeolli lees fiber. However, protein solubility and electrophoretic patterns did not differ among the control and treatments with Makgeolli lees fiber samples. The chicken salt-soluble protein heat-induced gel systems incorporating Makgeolli lees fiber had improved water holding capacity, textural properties, and viscosity due to Makgeolli lees fiber addition. These results suggest that the addition of 4.0% Makgeolli lees fiber to gel is helpful to improve the physical properties of heat-induced gels.

This study was conducted to investigate the effects of Takju lees hot water extracts on the blood pressure in spontaneously hypertension rats (SHR). Twenty eight male SHR were grouped by their blood pressure and fed a control diet or experimental diets containing 1% (G1), 2% (G2), or 4% (G4) Takju lees extracts for 4 weeks. Food intake was not significantly different among the groups. However, body weight gain was significantly lower in groups fed the Takju lees extract than the control group. The systolic blood pressure was significantly lower in the Takju lees extract containing groups (especially in G4 group) than the control groups. In addition, mean blood pressure {(systolic+dyastolic)/2} decreased with an increase in the amount of Takju lees extract in the diet and feeding period. Takju lees extract decreased angiotensin I converting enzyme (ACE) activity in a dose-dependent manner. These results suggest that the Takju lees extract exert an antihypertensive effect by decreasing ACE activity.
