“…In a similar way, in a mountain environment different from the Alpine ones investigated in our study, a similar richness in the terpenoid profile of the plant species of a mountain pasture located in an eastern region of Northern Spain has been found by Valdivielso et al [40]. These authors detected more than 75 different individual terpenoids and reported that the total abundance of monoterpenoids was lower than that of sesquiterpenoids in most botanical families and that the most abundant monoterpene in Lamiaceae, Asteraceae, and Ericaceae were α-pinene, isoeugenol, β-thujene, and linalool.…”

A study was conducted over the summer of 2014 on nine Alpine pastures in the Chisone and Susa Valleys (NW Italy). The aim was to characterize the variation in the chemical composition, gross energy, in vitro true digestibility (IVTD), in vitro neutral detergent fiber digestibility (NDFD), fatty acids (FA), total phenols, total and condensed tannin contents, and terpenoid profile. The dry matter, ash, crude protein, acid detergent fiber, lignin, and gross energy contents of the pastures were found to differ. All the pastures had good IVTD (706–829 g/kg DM) and NDFD (487–694 g/kg NDF) values. The most abundant FAs in all the pastures were α-linolenic (354–519 g/kg of the total FAs), linoleic (75–110 g/kg of the total FAs), and palmitic acid (64–89 g/kg of the total FAs) and they differed significantly among pastures. No significant differences were found in the total phenols, or in the total and condensed tannin contents among pastures. Fifty-eight terpenoids were detected and 4-cyclopentene-1, 3-dione, β-caryophyllene, and eucalyptol were the most abundant. The terpenoids differed both qualitatively and quantitatively among pastures. The results highlight the importance of the great biodiversity of pastures, which provide a balanced distribution of fundamental nutritional elements and bioactive compounds in grasslands.

“…[16] SPME-gas chromatography-mass spectrometry (GC/MS) technique has been used in analysis of volatiles of milk. [4,13,17,18] In the present study, we sampled the UHT milks with the similar expiration date and fat content in order to elimination the effects of storage period and fat content on VCs. Therefore, we aimed to determine the changes in VCs and OA contents in the UHT milk samples with the similar basic nutrient components, packing materials, and the expiration date.…”

A study was conducted to evaluate the basic chemical composition, organic acids and volatile compound profiles of ultra-high-temperature milk samples sold in Turkey. The organic acids were determined by reverse-phase highperformance liquid chromatography method, and volatile compounds were analyzed by headspace solid phase micro-extraction/gas chromatography/ mass spectrometry technique. A total of 43 volatile compounds including 4 aldehydes, 5 alcohols, 10 ketones, 9 acids, 9 aromatic hydrocarbons, 3 nitrogenous, 2 sulfur containing compounds, and 1 alkane hydrocarbon, were identified in the ultra-high-temperature milk samples. The main compounds were found to be oxime methoxy phenyl, 2-heptanone, 2-mercapto-4-phenylthiazole, 2amino-5-ethoxycarbonyl benzophenone, acetic acid, 2,6,10,14-tetramethyl pentadecane, and 2-nonanone. The main organic acid in the ultra-high-temperature milk was citric acid a mean value of 133 mg/100 mL, followed by formic,

“…Cheese produced from total mixed ration (TMR)-fed or pasture-fed cows differed in terpenoid contents, for example, l-carvone identified in some pasture species and present in the respective cheese, was not found in the TMR-derived cheese (Carpino et al, 2004).

Safety and efficacy of secondary alicyclic saturated and unsaturated alcohols, ketones, ketals and esters with ketals containing alicyclic alcohols or ketones and esters containing secondary alicyclic alcohols from chemical group 8 when used as flavourings for all animal species

[09.017] are safe only at concentrations below the proposed use levels (0.5 mg/kg for cattle, salmonids and non-food producing animals, and 0.3 mg/kg for pigs and poultry). No safety concern would arise for consumers from the use of these compounds as proposed in feeds. Hazards for skin and eye contact, and respiratory exposure are recognised for the majority of the compounds under application. Most are classified as irritating to the respiratory system. Use of the majority of the compounds in animal feed at the maximum safe level is considered safe for the environment. As all of the compounds are used in food as flavourings and their function in feed is essentially the same as that in food no demonstration of efficacy is necessary.
