| 日本短角種は優れた母性能力を持っており，これを活かした生産方式として一産肥育が考えられる．本研究では一産肥育牛の視覚的に評価可能な肉質および食味を未経産牛と比較調査した．一産肥育牛および未経産牛それぞれ3頭のロースおよびモモを用い，格付8形質，筋間脂肪22形質および食味4形質を分析した．官能評価は二点嗜好法を用い，ロース（筋間脂肪を含む）およびモモ（筋肉部分のみ）をローストビーフで提示した．格付および筋間脂肪では，肉量および筋間脂肪量は一産肥育牛の方が多い傾向であった．食味では，ロースは未経産牛の方が柔らかく食味性が優れる傾向にあったが，モモは一産肥育牛が好まれた．ロースの食味支持率といくつかの筋間脂肪割合との間に負の相関がみられたことから（P<0.05），部位間の結果の相違はサンプルの筋間脂肪の有無に影響された可能性が考えられた．しかしながら，余分な筋間脂肪の付着を抑えることで，ロースにおいても一産肥育牛の食味性が向上する可能性があり，一産肥育は視覚的な肉質および食味において未経産牛に劣らない可能性が示された． |

| Recently, we have identified the ubiquitin conjugate, protein phosphatase inhibitor 1 (I1), from postmortem muscles. Since I1 is one of the important regulators of glycogen metabolism, the effect of this conjugate (Ub-I1) present in postmortem muscle on glycolysis was investigated. Two sample groups were distinguishable: those not containing Ub-I1 (I, n=5)and those containing Ub-I1 (II, n=27). Due to the enormous variation in ultimate pH at 48 h postmortem, the latter group was subcategorized into a IIa group showing lower or normal pH and a IIb group showing higher or dark, firm, dry meat pH. Postmortem glycolysis occurred rapidly and vigorously among group I samples. The rate and extent of postmortem glycolysis was typical in group IIa samples while it... |

| In this study we compared the hypocholesterolaemic ability of two potato peptide preparations in rats. Experimental groups were fed for 4 weeks, with casein as the basal diet, in comparison with two diets containing 20% potato peptide preparations PPS (Short hydrolysis preparation) and PPL (Long hydrolysis preparation). Serum total cholesterol and serum triglyceride level were lower in PPS-fed group compared with CN-and PPL-fed groups. Lower non-HDL cholesterol level (P<0.05) in both PPS-and PPL-fed groups, was followed by higher neutral sterol excretion, and higher hepatic LDL-R and SR-B1 mRNA level than the control. Hepatic SREBP-2 and HMG-CoA reductase mRNA level were higher in PPL-fed group compared with the CN-fed group (P<0.05). Caecal total... |

| We investigated lipid oxidation, instrumental color evaluation, and sensory characteristics in cooked pork sausages containing anthocyanin rich colored potato (Solanum tuberosam cv. Shadow Queen) flakes (CPF). According to the thiobarbituric acid reactive substance values, addition of 2% CPF suppressed lipid oxidation (P < 0.05) by 80% compared to the control. The antioxidant activity of 2% CPF was comparable to the synthetic antioxidant butylated hydroxytoluene (0.1%) in cooked pork sausages. The L, a* values and odor, flavor, taste, texture and overall sensory quality did not significantly differ between control and 2% CPF. Overall, cooked pork sausage with 2% CPF was as acceptable to consumers as the control. Thus, the present study indicated that... |

| This study examined the effects of food additives on gram-negative bacteria. The food additives used included synthetic antioxidants (butylated hydroxyanisole, BHA, and butylated hydroxytoluene, BHT), a curing agent and lactic acid with or without a cell-free supernatant (CFS) containing antimicrobial compounds of Lactobacillus sakei D-1001. The gram-negative bacteria were selected from dry-fermented sausages and cultured with different food additives for 18 h in nutrient broth, and then another 24 h with or without CFS adjusted (at pH 6.0) to inactivate lactic acid or not adjusted (at pH 4.0). BHA (0.1%) resulted in total viable cell inhibition following 18 h culture. A reduction in cell growth was observed in culture broths with 0.1% lactic acid and... |

| 近年，機能性が注目されているベタインを一般的な加工食品に利用することを目的に，食パン生地にベタインを高配合したときの製パン性に与える影響を検討した．まず，食パンに，ベタインをパン生地の小麦粉に対して1∼5%添加したところ，生地からのガス発生量は，ベタイン添加量に依存して減少し，ホイロ時間が増加した．特に，機能性付与を目的とした5 %の配合では，製パン性は大きく劣化し，比容積は11%低下した．次に，食パンにベタインを高濃度に配合したときの影響を低減する方法として，ミキシング前に添加する方法に対して，ミキシング後半に添加した場合の食パンの物理特性や食感に及ぼす影響を詳細に調べた．その結果，ベタイン添加によるガス発生量およびガス保持性の低下は，ミキシング後半に添加することで大幅に改善し，比容積も有意に（p<0.05）改善した．ベタイン添加による比容積の低下は，クラムの硬さと高い負の相関がみられ，クラムの硬さが有意に（p<0.05）増加するとともに，クラストの硬さが低下したが，ベタインの添加をミキシング後半とすることで，ネガティブコントロールの硬さに近い値にまで改善された．これらの結果は，食感に関する官能評価の結果とも一致していた．走査型電子顕微鏡（SEM）による生地の組織像から，ベタインを高配合すると，ミキシングおよび発酵時にグルテンネットワークの形成が十分に形成できていないこと，ミキシング後半の添加とすることで，無添加の生地に近い状態に改善する様子が観察された．以上の結果から，食パンにベタインを高配合する場合は，添加時期を遅らせることで製パン性への影響を小さくできると考えられた． |

| We examined the effects of Amylomyces rouxii, which is a mold found in some fermented foods in Indonesia, on serum cholesterol and hepatic LDL receptor mRNA in rats. Rats were fed a 0.5% cholesterol-enriched diet with (A. rouxii group) or without (control group) 30g/kg A. rouxii for 4 wk. There were no significant differences in the body weight, food intake or liver weight among the groups. However, the weight of the cecum in the A. rouxii-fed group was significantly higher than that in the control group. The cecal pH in the A. rouxii-fed group was significantly lower than that in the control group. Cecal acetic acid, propionic acid and total SCFA concentrations in the A. rouxii-fed group were significantly higher than those in the control group. The serum... |
