 C. maritimum L. produces a high measure of reasonable natural products that can sprout with no burden, particularly in refined water. Ocean fennel (Crithmum maritimum L.), a lasting halophyte commonplace of beach front propensities, is notable for a few food and non-food employments. This audit presents both the qualities and ethno botany just as the discoveries, specialized advances and capability of ocean fennel examine with the mean to improve and disperse information in regards to the worth and possibilities of this halophyte. Momentum information recommends that ocean fennel shows great potential as a rising yield, being a refined food and furthermore a fascinating wellspring of human wellbeing mixes and crop insurance items. Additionally, ocean fennel might be proposed as another option and economical money crop likewise with regards to a saline agribusiness system. The ocean fennel is a wild plant from a similar group of the parsley and celery that is utilized as a new element for some food arrangements. In this work, some option culinary utilizations for this sweet-smelling plant as a dried fixing have been proposed. In any case, the characteristic items got from plants show a more noteworthy intrigue for purchasers and gourmet experts. As a result, the presentation of new flavors and regular colorants from plants could invigorate new open doors for gastronomy. The airborne pieces of wild-developed ocean fennel were collected in Central Dalmatia (Split, Croatia) during blooming stage. The plant material (blossoms, stems and leaves) was air-dried for 10 days at room temperature in a concealed and circulated air through spot. For the concentrate readiness dried plant material was pounded (1 min in rapid processor) into powder. Thus, two drying innovations were applied with the mean to acquire another zest colorant without synthetic blend. The outcomes are examined regarding visual quality, smell and taste of the dried out items. Additionally, the impacts on the general tangible properties of certain dishes arranged utilizing the two distinct kinds of this new flavor are accounted for. The presentation of the dried ocean fennel in gastronomy could build the tactile intrigue of some customary dishes and bolster the formation of numerous new plans. Then again, a few parts of ocean fennel require further seeing; in this manner, new innovative work exercises ought to be completed before full business misuse. In any case, in spite of the way that this halophyte as a rule becomes close to the seawater, seed germination is hindered when salinities surpass 50 mM NaCl. In the normal living space, ocean fennel organic products are constantly presented to a few particles, for example, Na+, Mg2+, Ca2+, Cl−, and SO42−. Sodium salts unfavorably influence seeds germination right off the bat by means of the osmotic impact; it isn't the situation that a high germination recuperation can be watched if seeds are moved in refined water. In this manner, it is conceivable to guess that in nature, despite the fact that ocean fennel seeds stay reasonable with high saltiness conditions, the germination begins toward the start of the spring, simply after salt draining which is because of the winter precipitations. Another fascinating perspective in regards to the ocean fennel seed germination is the way that it's natural products can be viewed as a dispersal unit. Both secretory envelope and springy coat can shield ocean fennel seeds from the harm because of potential Na+ and Cl− amassing. Besides, the high drifting limit along with the germination recuperation for clarifying the significant distance seed dispersal and the ensuing plants development. Aside from the nourishing qualities and natural action of ocean fennel, a few commitments are accounted for in writing with respect to some culinary and people employments of various ocean fennel-based items. Consequently, so as to assess whether ocean fennel can be viewed as a developing vegetable yield with a solid opportunity to succeed, a SWOT investigation was performed. SWOT (Strengths, Weaknesses, Opportunities and Threats) investigation involves the examination of the qualities and shortcomings of an undertaking, item, spot or individual and their relationship with the chances and dangers of the environmental factors. To put it plainly, it is a structure for distinguishing and examining the inside and outside variables that can affect the suitability of a task, item, spot or individual. SWOT investigation could be considered as a significant help apparatus for dynamic and is regularly utilized as an approach to methodically examine the inner and outer situations of undertaking, items and associations. It Reports the SWOT examination in regards to the abuse of ocean fennel as an elective money crop.

Crithmum maritimum (sea fennel) is a halophyte plant that grows spontaneously along the Italian East coasts, it is equipped with adaptive mechanisms that enable it to complete its entire life-cycle at high salinity and hence to generate economic yields although exposed to salt stress conditions. Its valuable nutritional and functional traits (i.e. high content in C vitamin, flavonoids, polyphenols, etc.) makes this blue source a sustainable and economically valuable opportunity for industrial manufacturing/commercialization of high value products. Currently, sea fennel is only marginally exploited by few artisan or semi-industrial enterprises for manufacturing of unfermented preserves in brine or olive oil, pesto-like sauces, fresh-cut and semi-finished products and no fermented preserves are commercialized, yet in either national and international markets. Given these premises, this research was aimed at exploiting Italian sea fennel cultivars with a high adaptation to Adriatic climates, high nutrients density and unique functional properties for the production of fermented sea-fennel based preserved. To this end, the microbiota dominating during the natural fermentation of sea fennel sprouts in brine was monitored by using culture-dependent (viable counting, isolation of pure cultures) and independent microbiological methods (PCR-DGGE and next-generation sequencing). In parallel, the main technological parameters of the fermented sea fennel sprouts (pH, TTA, lactic acid and acetic acid content, C vitamin content) and the isolated lactic acid bacteria cultures (acidifying activity, CO2 production, etc.) were also investigated. As a result, the main lactic acid bacteria species guiding the fermentation were identified, isolated and preliminary characterized.
