神经酰胺3主要用作各类化妆品保湿剂。尽管有一些对于包含伪神经酰胺或者神经酰胺配方的安全性研究,已经经过监管部门的批准,在临床前和临床水平实施,并没有研究已经评估神经酰胺3的系统性毒性。为了解决这个问题,我们对神经酰胺和伪神经酰胺进行了风险评估和综合毒性评估。我们假设神经酰胺3存在于各种个人和美容产品浓度的0.5-10%。基于之前报道曝光数据,安全边际(MOS)适合于产品类型,使用模式和神经酰胺3浓度。口红中含有10%神经酰胺(MOS=4111)被认为是安全的,而含有0.5%神经酰胺3(MOS = 148)的洗发水是公认安全的。对身体乳液而言,手部(含1%神经酰胺3)和背部(含5%神经酰胺3)的安全边际值(MOS)分别是103和168.我们预计,面霜将含3%浓度的神经酰胺(MOS=149)是安全的。总的来说,该MOS方法表明对于含有小于1%的神经酰胺3化妆品是没有安全问题的。

Methods for determination of milk cholesterol concentration were compared, with particular emphasis on an enzymatic method (ME). Bovine and human milk samples (n = 40) were pre-treated and analysed by three different protocols: (i) IDF Standard with gas chromatography (GC); (ii) direct saponification (DS) and GC; (iii) DS and ME with spectrophotometric determination. A simplified method (DS + ME) was developed with an acceptable coefficient of variation. The cholesterol concentration values assessed by DS + ME were higher compared with DS + GC. There were no statistically significant differences between the results obtained by the enzymatic and IDF method (P = 0.09). The mean cholesterol concentrations in bovine and human milk were 16.71 ± 4.21 mg dL−1 and 2.80 ± 0.65 mg dL−1, respectively. The new method developed was less time-consuming and more economical, and could be suitable for large-scale studies. High recovery (95%) obtained by ME indicates that the results are reliable and could be the basis for routine analysis.

The aim of the study was to examine the effects of genotype (Pannon Large × Pannon Ka/Large/or Hungarian Giant × Pannon Ka/Hung), housing system (Cage or small Pen) and hay supplementation (Pellet without or with Hay/P + Hay/) on carcass and meat (Longissimus dorsi/LD/ and hind leg/HL/) quality of growing rabbits. Large rabbits showed higher carcass weights, as well as higher fatness and meatiness compared to Hung rabbits. Caged rabbits were heavier, with higher prevalence of the mid part of the carcass, and showed higher fatness and lower meat toughness than Penned rabbits. Caged rabbits meat was richer in MUFA, but poorer in PUFA and Σ n− 6 FA. Hay supplementation impaired carcass weight, carcass fatness, L* and a* color, and lipids content. P + Hay increased the HL meat content of C18:3 n− 6 and C20:5 n− 3 FA. Overall results offer further information on how alternative breeds, housing systems and feeding strategies can affect carcass traits and meat quality.

The objective of our study was to evaluate the combined effects of ageing period and different freezing rates on meat quality attributes of beef loins. Pairs of loins (M. longissimus at 1 day post mortem) from 12 carcasses were divided into four equal portions and randomly assigned to four ageing/freezing treatments (aged only, frozen only, and 3 or 4 weeks ageing at − 1.5 °C then frozen). Two freezing methods (fast freezing by calcium chloride immersion or slow freezing by air freezer at − 18 °C) were applied to the loin sections. Fast freezing had no effect on shear force (P > 0.05), but significantly improved the water-holding capacity of the aged/frozen loins by reducing purge and drip losses. Ageing-then-freezing significantly improved shear force values of loins compared to both the aged only and frozen only loins. These observations suggest that fast freezing will add more value to the aged/frozen/thawed meat by minimising the amount of water-loss due to the freezing/thawing process.

We investigated the physiological changes in scallops (Chlamys farreri) during semi-anhydrous living-preservation using metabolomics method to obtain a guiding theory in optimizing the preservation conditions. Glycogen, lactic acid, and crude protein levels were measured in 1-day intervals for 6 days, the median lethal time.

The metabolite profiling of scallops after the preservation duration of 10% lethal time (3 days) was achieved based on methyl chloroformate derivation before GC-MS analysis. Carboxyl acids related to respiration (malic, fumaric, and succinic acids), fatty acids (C18:0, C16:0, and C22:6), and amino acids (phenylalanine, glutamic acid, aspartic acid, isoleucine, glycine, pyroglutamic acid, proline, leucine, and 2-aminoadipic acid) were identified as biomarkers. Our results demonstrated that scallops performed an elevated anaerobiosis and depressed aerobiosis, which were not caused by oxygen insufficiency. The switching of energy metabolism patterns and disorder of the osmotic regulation system were also observed, suggesting that oxygen supply is less important for optimizing semi-anhydrous living-preservation.

在干酪技术中,扩散现象在成熟过程中至关重要。为研究分子的扩散和奶酪成分或其微观结构之间的关系,漂白后荧光恢复技术被首次应用在真正的奶酪上。软质和硬质干酪的右旋糖酐群 (10-500 kDa)测量有效扩散系数,被发现与使用类似的无脂奶酪模型观察到值 (∼0.1-20 μm2 s−1)在相同的数量级。右旋糖酐扩散是主要取决于从奶酪中提取出来的“自由”水相的成分,紧紧与奶酪制作工艺和成熟期相联系。扩散系数通过作为一个右旋糖酐分子量的函数的幂律关系进行了模拟,允许一些对奶酪微观结构的研究。一个严格的蛋白网络将需要一些具有较高的分子量(大于250 kDa)的变形的灵活大分子,以从这种奶酪的孔隙结构里扩散出去。

Increased meat toughness with animal age has been attributed to mature trivalent collagen cross-link formation. Intramuscular trivalent collagen cross-link content may be decreased by reducing animal age at slaughter and/or inducing muscle re-modeling with growth promotants. This hypothesis was tested in m. gluteus medius (GM) and m. semitendinosus (ST) from 112 beef steers finished at either 12 to 13 (rapid growth) or 18 to 20 (slow growth) months of age. Hereford–Aberdeen Angus (HAA) or Charolais–Red Angus (CRA) steers were randomly assigned to receive implants (IMP), ractopamine (RAC), both IMP and RAC, or none (control). RAC decreased pyridinoline (mol/mol collagen) and IMP increased Ehrlich chromogen (EC) (mol/mol collagen) in the GM. In the ST, RAC increased EC (mol/mol collagen) but decreased EC (nmol/g raw muscle) in slow growing CRA steers. Also, IMP increased ST pyridinoline (nmol/g raw muscle) of slow-growing HAA steers. Results indicated alteration of perimysium collagen cross-links content in muscle in response to growth promotants.

This paper presents the study on impact of elicitation and the phenylpropanoid pathway feeding on the nutritional quality, the potentially bioaccessible phenolics and the antioxidant capacity of young buckwheat sprouts. Phenolics content was increased by elicitation and feeding with tyrosine and shikimic acid – an elevation of 30% and 17%, respectively. Antioxidant capacity was improved by feeding with tyrosine – an increase of 16.7% and 17.1% in both untreated and treated sprouts, respectively. The highest protein digestibility was determined for the control sprouts and those obtained after tyrosine feeding. The lowest starch digestibility was found for elicited sprouts obtained from seeds fed with tyrosine (a decrease by 52%). An increase of expected glycemic index by 38% was determined for elicited sprouts obtained after phenylalanine feeding. Starch and protein digestibility were negatively correlated with total phenolics (r = −0.55 and −0.58, respectively), however starch digestibility was also affected by resistant starch content.

The effect of preparation and storage parameters on the number, size and stability of microbubbles covered with bovine serum albumin (BSA) was investigated. A large number of microbubbles with a high stability was obtained at protein concentration of 7.5% or higher, at pH between 5 and 6, at an ionic strength of 1.0 M and at a preheating temperature of 55–60 °C. Microbubbles stored at 4 °C were more stable than those stored at room temperature. This was observed for a specific commercial BSA batch. We found that optimal preparation parameters strongly depend on the batch. Certain BSA batches were found not to lead to microbubbles at all. Microbubbles made with different protein concentration and preheating temperatures shrunk in time to a radius between 300 nm and 350 nm, after which the size remained constant during further storage. We argue that the constant final size can be explained by a thickening of the microbubble shell as a result of the microbubble shrinkage, thereby withstanding the Laplace pressure. The effects of protein concentration, pH and ionic strength on the number of microbubbles directly after sonication can be ascribed to the influence of these parameters on the adsorption speed and ability to cover the surface of air bubbles formed during sonication with enough protein to stabilize the bubble against coalescence and dissolution. We suggest that the effect of temperature during sonication on the formation of microbubbles can be related to thermally induced protein–protein interaction at the air–water interface.
