“…These products were well accepted by consumers. Shahein et al [ 21 ] evaluated the microbiological and physicochemical characteristics of frozen yoghurt made with probiotic strains in combination with Jerusalem artichoke tubers powder (JATP) used as a fat and sugar replacer. Samples with JATP contained viable counts of Bifidobacterium bifidum BGN4 and Lactobacillus casei Lc-01 of 7 log CFU/g during 90 days of storage, as compared to the control sample.…”

“…The production of frozen yoghurts or ice creams with low fat or lactose levels and/or with added prebiotics and probiotics created new opportunities for the development of dairy foods with health-promoting properties. An increasing number of papers describe the formulations and characteristics of such products [ 18 , 19 , 20 , 21 , 22 , 23 , 24 , 25 , 26 , 27 , 28 , 29 , 30 , 31 ]. The production of ovine’s and caprine’s yoghurts and frozen yoghurts has also followed this trend.…”

Second cheese whey (SCW) is the by-product resulting from the manufacture of whey cheeses. In the present work, sheep (S) and goat (G) SCW concentrated by ultrafiltration (UF) were used in the production of ice creams. Concentrated liquid SCW samples with inulin added as a prebiotic were fermented with yoghurt, kefir and probiotic commercial cultures before being frozen in a horizontal frozen yoghurt freezer. The physicochemical, microbiological and sensory properties of the products were evaluated over 120 days of frozen storage. The products presented significant differences regarding these properties, specifically the higher total solids and protein contents of sheep's ice creams, which were higher compared to their goat ice cream counterparts. Sheep’s ice creams also presented higher hardness and complex viscosity, which increased with storage. These ice creams also presented higher overrun and lower meltdown rates. The color parameters of the ice creams showed significant differences between formulations resulting from storage time. In all cases, Lactobacilli sp. cell counts were higher than log 6 CFU/g at the first week of storage. In the case of sheep’s ice creams these values were maintained or increased until the 30th day, but decreased until the 60th day. Lactococci sp. counts surpassed log 7 CFU/g in all products, and these values were maintained until the end of storage, except in the case of G-Yoghurt and G-Kefir. Concerning the products containing probiotics, the sum of Lactococci sp. and Lactobacilli sp. counts was of the order log 8–9 CFU/g until the 60th day of storage, indicating that the probiotic characteristics of ice creams were maintained for at least 2 months. All products were well accepted by the consumer panel. Sheep’s SCW ice creams were better rated regarding aroma, taste and texture. However, only the ranking test was able to differentiate preferences among formulations.

“…Fortifications of dairy products with natural substances enhance the physicochemical characterizations and nutritive values of functional food, and therefore, have attracted many research projects over the last few decades [21][22][23][24][25][26][27][28][29]. Many studies reported that herbal therapy is considered an effective way to the management of diabetes.…”

The incorporation of fermented camel milk with natural additives possesses numerous benefits for the treatment of various pathological and metabolic conditions. The present study investigated the impact of fortification of fermented camel milk with sage or mint leaves powder (1 and 1.5%, respectively) on glucose and insulin levels, lipid profile, and liver and kidney functions in alloxan-induced diabetic rats. The gross chemical composition of sage and peppermint leaves powder was studied. The chemical composition of sage and mint extracts was performed using liquid chromatography–electrospray ionization–tandem mass spectrometry (LC-MS) of sage and mint extracts. Furthermore, a total of forty-two adult normal male albino rats were included in this study, whereas one group was kept as the healthy control group (n = 6 rats) and diabetes was induced in the remaining animals (n = 36 rats) using alloxan injection (150 mg/kg of body weight). Among diabetic rats groups, a control group (n = 6 rats) was kept as the diabetic control group whereas the other 5 groups (6 rats per group) of diabetic rats were fed fermented camel milk (FCM) or fermented camel milk fortified with 1 and 1.5% of sage or mint leaves powder. Interestingly, the oral administration of fermented camel milk fortified with sage or mint leaves powder, at both concentrations, caused a significant decrease in blood glucose level and lipid profile, and an increase in insulin level compared to the diabetic control and FCM groups. Among others, the best results were observed in the group of animals that received fermented camel milk fortified with 1.5% sage powder. In addition, the results revealed that the fermented camel milk fortified with sage or mint leaves powder improved the liver and kidney functions of diabetic rats. Our study concluded that the use of sage and mint leaves powder (at a ratio of 1.5%) with fermented camel milk produces functional food products with anti-diabetic activity.

Frozen yoghurt rich in b-carotene and dietary fibre was developed through incorporation of orange peel products. The suitability of two forms of peel viz., candied orange peel (COP) and orange peel powder (OPP), was studied as flavour adjunct in frozen yoghurt. The medium-fat frozen yoghurt mix was prepared by blending yoghurt base with ice cream mix (25:75, w/w). COP and OPP were used as flavour adjuncts at levels of 8.0 and 2.5% by weight of mixes, respectively. The control (C) frozen yoghurt was devoid of the fruit peel. Incorporation of peel solids yielded frozen yoghurts which had markedly higher protein, carbohydrates, ash and total solids content. OPP used at 2.5% level was preferred over use of COP at 8.0% level as a valued ingredient in the preparation of 'medium-fat orange frozen yoghurt'. Such product had superior total sensory score when compared to the rest of the samples. The recommended frozen yoghurt was higher in terms of b-carotene and dietary fibre by 37.20 and 240.0%, respectively, compared to control product.
