Thanks for reviewers’ comments concerning our manuscript entitled “EFFECT OF FLAXSEED MUCILAGE AND GUM ARABIC ON KEFIR PROPERTIES” (ID: foods-2158107). It is clear that you have a deep knowledge of the research in the field and ask very specialized questions. Those comments are all valuable and very helpful for revising and improving our paper, as well as the important guiding significance to our researches. We have selected native English speaking professionals to touch up the language and grammar of the text. We have studied the comments carefully and made correction which we hope meet with approval

Reviewer 2 Report
foods-2158107-peer-review-v1
The study investigated the survival probiotic cultures in kefir, focusing on the viability of Lactobacillus acidophilus, Bifidobacterium lactis. This was achieved by adding in the fermentation procedure flaxseed mucilage and gum arabic. Through their tests the author provided evidence that flaxseed mucilage and gum Arabic combination increase the growth of two important probiotics for human health the Lactobacillus acidophilus and the Bifidobacterium lactis.
Overall, the paper is interesting but not well written at all. The hypothesis and purpose of study are not clearly and nor concisely presented. Yogurt starter culture use in the experimental procedure should be introduced. In materials and methods section all research components are not present and nor clearly stated.
Abstract should be like this. Please do not use abbreviation in the abstract. There are several grammatical errors along the text that must be resolved.
Abstract
This study aimed to assess the survive of probiotic cultures in kefir. Kefir is a fermented dairy product and here, incorporating nutritionally rich flaxseed mucilage and gum arabic as a prebiotic we monitored the viability of Lactobacillus acidophilus and Bifidobacterium lactis. Also, some physicochemical variables of kefir were investigated. The addition of flaxseed mucilage and gum arabic significantly (PË‚0.05) increased the growth of both, Lactobacillus acidophilus and Bifidobacterium lactis compared to the control. Samples enriched with flaxseed mucilage and gum arabic had significantly (PË‚0.05) decreased the pH and increased viscosity. Flaxseed mucilage and gum arabic significantly (PË‚0.05) changed the color parameters L*, a*, and b*. However, as the concentration of flaxseed mucilage increased, the L* value decreased. Moreover, adding flaxseed mucilage and gum arabic into kefir increased (PË‚0.05) the protein contents. These results showed that flaxseed mucilage and gum arabic could use to increase the survival of probiotic cultures in kefir without changing its physicochemical properties.
