概括
与控制养的猪相比,养高纤维,富含omega-3料 (Bio+) 的有机猪具有更强烈的红肉颜色,但香味持久性较小. 这种养策略影响了感官特征,但没有改变有机猪肉的质地,气味或风味.
科学领域:
- 动物科学动物科学
- 食品科学 食品科学 食品科学
- 有机农业 有机农业 有机农业
背景情况:
- 猪肉质量受到各种因素的影响,包括动物饮食和农业做法.
- 有机农业标准要求特定的料成分.
- 评估新型料策略对于优化有机猪肉生产至关重要.
研究的目的:
- 评估富含纤维和omega-3脂肪酸的有机试验料 (Bio+) 对猪肉质量的影响.
- 为了比较猪肉的感觉和挥发性化合物概况,猪被养Bio+饮食与标准有机饮食 (控制) 相比.
主要方法:
- 77只雄猪 (Piétrain × 大白) 被分配到控制或Bio+养组.
- 猪是在有机农业条件下养的,随意食.
- 使用感官面板和SPME-GC-MS对挥发性化合物进行了分析.
主要成果:
- 生物+养的猪表现出显著更红的生肉颜色 (P < 0.01) 和较低的芳香持久性 (P < 0.05).
- 来自Bio+猪的肉类往往不那么柔软 (P = 0.08).
- 鉴定了27种挥发性化合物,在Bio+养的猪中多样性更高;然而,养策略没有显著区分整体挥发性特征或野猪污染.
结论:
- 生物+养策略影响特定的感官特征,特别是生肉的颜色和芳香的持久性.
- 这种饮食不会对熟的有机猪肉的猪肉质地,气味或味道产生负面影响.
- 进一步的研究可以探索优化Bio+料成分以提高猪肉质量属性.

NMR Spectroscopy of Aromatic Compounds
5.1K
Aromatic compounds can be identified or analyzed using proton NMR and carbon‐13 NMR. Typically, aromatic hydrogens or hydrogens directly bonded to the aromatic rings are strongly deshielded by the aromatic ring current. Therefore, they absorb in the range of 6.5–8.0 ppm in proton NMR spectra. For instance, aromatic hydrogens directly bonded to the benzene ring absorb at 7.3 ppm. However, aromatic hydrogens of larger rings absorb farther upfield or downfield than the ideal range.

Olfaction
45.2K
The sense of smell is achieved through the activities of the olfactory system. It starts when an airborne odorant enters the nasal cavity and reaches olfactory epithelium (OE). The OE is protected by a thin layer of mucus, which also serves the purpose of dissolving more complex compounds into simpler chemical odorants. The size of the OE and the density of sensory neurons varies among species; in humans, the OE is only about 9-10 cm2.

Aromatic Compounds: Overview
11.7K
In general, the term ‘aromatic’ indicates a pleasant smell or fragrance from fresh flowers, freshly prepared coffee, etc. In the early history of organic chemistry, many benzene derivatives were isolated from the pleasant odor oils of the plants. For example, vanillin was isolated from the oil of vanilla, methyl salicylate from the oil of wintergreen, and cinnamaldehyde from the oil of cinnamon. They all had a pleasant odor; hence the name aromatic was given.
