“…Thus, as expected, higher total solids, fat, and protein contents were found in GCY than in GMY ( Table 3 ) as well as lower lactose content and higher acidity values. These results agree with those reported by other authors when making fermented products from cow milk [ 12 , 13 , 32 , 33 ] and buffalo milk [ 11 ] fortified with different proportions of bovine colostrum in milk (8–100%). Thus, higher contents of fat, protein, total solids, and lactic acid were obtained in the final products as the proportion of colostrum increased.…”

“…In recent years, several studies have been conducted focusing on the use of bovine colostrum as a natural ingredient to improve the nutritional value and immune benefits of yogurts, and other fermented milks such as kefir [ 11 , 12 , 13 ]. However, there is little information on the use of goat colostrum for the production of new dairy products.…”

The aim of this study was to investigate the potential use of goat colostrum to produce a yogurt-type product as a novel functional dairy food. Four batches of fermented goat colostrum (GCY) were produced using fermented goat milk (GMY) as a reference. Physicochemical, mechanical, and microbial characteristics of cold storage fermented products were evaluated in a weekly basis for 28 days. Sensory analysis was applied to detect potential differences between products and to evaluate the acceptance of GCY by consumers. Results indicate that colostrum showed higher coagulation times than goat milk (480 vs. 350 min to reach pH 4.6). In general, GCY showed a higher protein and fat content and similar features than GMY for most quality parameters, which were highly stable along time. Sensory evaluation led to significant differences between products related to their color and taste. The consumer acceptance test, using a 5 point-Likert scale, showed an overall acceptance of 3.90 ± 0.79 for GCY, with aroma and consistency being the sensory attributes having highest ratings (4.30 ± 0.80 and 4.20 ± 0.96, respectively). Therefore, fermenting goat colostrum with yogurt specific starters could be an interesting alternative to make use of surplus colostrum on farms, allowing for the diversification of commercial goat milk products with potential health benefits for the consumer.

“…The TSC of the samples significantly increased as a result of fermentation (p < 0.05); however, during refrigerated storage, no marked changes were noticed in either variant (p > 0.05). It should also be pointed out that the TSC of the CPC-15% sample was similar to the TSC reported for dairy full milk yogurts [40], whereas the TSC of CPC-20% was slightly lower than that reported for the Greek type of yogurt [41,42]. The changes in color parameters as well as total color difference (∆E) are summarized in Table 2.…”

Production and Characterization of Yogurt-Like Fermented Beverage Based on Camelina (Camelina sativa L.) Seed Press Cake

Plant-based fermented beverages are growing in popularity due to the rise in vegetarianism, health trends and ethical concerns. In this study, camelina (Camelina sativa L.) seed press cake (CPC, 15% and 20% w/w) was fermented using yogurt starter culture. The physicochemical properties of the samples, including pH, total acidity, color, viscosity, texture and rheological properties were investigated. Moreover, the lactic acid bacteria (LAB) viability, bioactive compounds and antioxidant activity were determined. During fermentation and 28-day refrigerated storage, the samples achieved a mean viable bacterial count of at least 1010 CFU/g, which is higher than the recommended bacteria level for traditional dairy yogurt (106 CFU/g). A significant acidification, consumption of reducing sugars, increase in free amino acids and polyphenolics was observed. In addition, CPC-based fermented samples showed good antioxidant potential. Textural and rheological characteristics were similar to dairy yogurt. Moreover, fermentation improved the sensory attributes of CPC, meeting consumers’ acceptance criteria. Thus, the study indicated that fermentation had a marked effect on the physicochemical, microbiological and functional properties of CPC. Therefore, the fermented CPC-based beverage has the potential to be a valid, value-added and novel alternative to dairy-based yogurt.

“…Kefir is made with several process variables, namely 100% fresh milk, milk-colostrum mixture (20:80%; 40:60%; 60:40%; 80:20%) and 100% colostrum. Fermentation is under room temperature for 24 hours Silva et al [23] This study aims to develop Greek style yoghurt with bovine colostrum variations. The bovine colostrum variations used were 0%, 10%, 20% and 30% which resulted in four new yoghurt formulations PGPR 2021…”

The COVID-19 pandemic continues to be a global issue that draws worldwide attention. Countries are racing to develop vaccines and drugs to combat the COVID-19 virus. Immunomodulators are used in some of the prevention efforts. Any drug or substance that affects the immune system is classified as an immunomodulator. Bovine colostrum is an example of an immunomodulator. Colostrum is the mammary gland’s first secretion after birth, and it differs from mature milk in that it contains more proteins, immunoglobulin-A, vitamins, minerals, bactericides (lactoferrin, lysozyme, and lactoperoxidase), and growth factors. This review examines immunomodulators across various perspectives and characteristics, as an alternative for increasing the body’s resistance, and possible mechanisms are discussed. This review thereby facilitates the choice of suitable immune enhancement for the prevention and treatment of COVID-19. Keywords: Bovine colostrum, Immonumodulator, Covid-19
