“…(1990) which recorded that ash content progressively increased as lactation proceeded. Although total ash shows least variation, the specific constituents of ash like minerals and trace elements may vary due to factors including environmental condition, animal feed and nutrition, lactation stage, animal species or breed, and contaminants ( Zain et al . 2016 ; Singh et al .…”

This study was conducted to determine the physical and chemical composition of goat milk produced by eight local farms located in the central region of Malaysia. Farms 1 to 4 (F1-SC, F2-SP, F3-SP, F4-SBC) reared Saanen-type goats while farms 5 to 8 (F5-JK, F6-JPEC, F7-JTC, F8-JC), Jamnapari-type goats. The common feedstuffs used in all farms comprised of fresh or silage from Napier grass, feed pellets, and brans while two farms, F5-JK and F6-JPEC supplemented the feeds with soybean-based product. The total solid content, dry matter, and proximate composition of goat milk and feedstuffs from the different farms were determined and the results analysed using principal component analysis. Total solid content of goat milk from the Jamnapari crossbreed had the highest solid content ranging from 11.81% to 17.54% compared to milk from farms with Saanen and Saanen crossbreed (10.95% to 14.63%). Jamnapari-type goats from F5-JK, F6-JPEC, and F8-JC had significantly higher (p < 0.05) milk fat and protein contents (7.36%, 7.14%, and 6.59% fat; 5.08%, 6.19%, and 4.23% protein, respectively) than milk from other farms but, milk produced by Saanen-type goats from F4-SBC contained similar protein content (4.34%) to that from F8-JC. Total ash and carbohydrate contents in milk ranged between 0.67% to 0.86% and 3.26% to 4.71%, respectively, regardless of goat breed. Feeding soybean-based products appear to have a positive influence on milk fat and protein content in Jamnaparitype goats.

“…A constellation plot is another way to present information in the hierarchical clustering dendrogram and is particularly useful for visualizing large data sets (for applications outside of archaeology, see Zain et al . ; SAS Institute Inc. , 157). Lines indicate cluster membership and the lengths of the lines represent distance between clusters.…”

Worldwide applications of ochre analysis continue to develop at a rapid pace, highlighting a number of analytical and interpretative issues. As regional source databases continue to grow, researchers have turned to the thornier issues of source allocation. In this study, we utilize LA-ICP-MS and NAA to examine archaeological pigments, ceramic paints and experimental tiles from geological sources and Hohokam ceramics in central Arizona. Archaeological pigments and paint on sherds are successfully source matched based on trace element content, with implications for understanding paint production, sociocultural relations governing trade in pigment and the use of different resource landscapes over time.

“…Inductively coupled plasma-mass spectrometry (ICP-MS) is a robust analytical technique to obtain useful information of samples composition without using complicated pre-treatments and providing accurate data based on mineral and trace elements. Table 3 also summarizes the main applications of ICP-MS in combination with multivariate analysis for origin authentication purposes in dairy products (Magdas, et al, 2016;Nečemer, Potočnik, & Ogrinc, 2016;Rodríguez-Bermúdez, et al, 2018;Zain, Behkami, Bakirdere, & Koki, 2016). -Lara, et al, 2017).…”

Background: Food fraud is described as a violation of food law, which is intentionally committed to get an economic or financial gain through the consumer's swindle resulting in multi-million business and posing a public health threat. The main fraudulent practices are mislabelling of composition, certificates of origin, health claims, and artificial increases in weight or volume caused by replacement, dilution, addition or removal of some ingredients. Hardly 68% of the food fraud violations are produced in animal and vegetable products with high fat content (27% meat, 13% fish, 11% oils, 10% dairy products, 4% nuts and seeds and 3% animal by-products) becoming a crucial issue for food processing industries. Scope and approach: The present review focuses on the main authentication techniques and methods employed to clarify the authenticity of both animal and vegetable fat food products emphasizing the importance of the use of robust and reliable analytical techniques combined with multivariate analyses. Key findings and conclusions: Targeted approaches, such as as chromatography and DNA-based methods, combined with multivariate analysis have shown high accuracy, sensitivity and selectivity, allowing the simultaneous evaluation of multiple analytes. In addition, non-target methods, such as those based on spectroscopic techniques, have been used to establish the geographic origin of food products with quick response, low cost, non-destructive character and also offering the possibility to be miniaturized.
