# Mefarek is a [[Toldah]] of Dosh. <ref>Rashi [[Shabbat]] 73b and Rambam ([[Shabbat]] 8:7 and 21:12) write that Mefarek is a [[Toldah]] of Dosh. <br />
One major difference between Mefareik and its Av is that Dosh is the removal of ochel from p’soles, something unwanted, which is not the case with squeezing juice from fruit. In order to maintain the comparison, the squeezing of the juice must be viewed as squeezing liquid from food. Therefore, the Gemara (144b) rules that squeezing juice directly into food (not drink) is permitted since then it is viewed as removing food from food and is not similar to Dosh where the extract is different than what it is removed from.<br />The Mishna
Berura (Sha’ar Ha’tziun Siman 320, no. 23) quotes a machlokes Rishonim regarding squeezing into a plate with the intention of subsequently pouring it into food. The Chazon Ish (O”C 55:6) rules that it is only permitted if it is direct and such is the opinion of Shmiras Shabbos k’Hilchisa (chap. 5, seif 5). See, however, Biur Halacha 320:1 s.v. muter </ref>
# Mefarek includes [[squeezing]] juice from fruit ([[Sechitah]]) or liquid from a cloth. <ref>Rambam ([[Shabbat]] 8:10 and 21:12) writes that [[squeezing]] fruit ([[Sechitah]]) is a violation of Mefarek. 39 Melachos (Dosh note 113) quotes Tosfot Ketubot 6a s.v. Hay who holds that [[squeezing]] a liquid from a cloth is also considered Mefarek. </ref>
# It is forbidden to squeeze a fruit in order to extract its liquid if one squeezes the fruit into a liquid or empty vessel. The prohibition is violated whether it is done by hand or with a utensil. <Ref> Shemirat [[Shabbat]] KeHilchata 5:1,2. [[Squeezing]] a liquid out of a solid ([[Sechita]]) is Mefarek which is a [[Toldah]] of the Melacha of [[Dash]] (Iglei Tal, [[Dash]] #8, Mishna Brurah 320:1).
* Shulchan Aruch 320:1 writes that it's forbidden to squeeze olives and grapes and the juice which flows from them on their own is also forbidden for consumption. However, berries and pomegranates even though they are forbidden to be squeezed the juices from them that flow on their own are permissible if the fruit was meant to be eaten and not be squeezed for the juice. Lastly, all other fruits may be squeezed. The Rama 320:1 explains that in places where it's normal to squeeze certain fruits for their juices it is also forbidden to squeeze those fruits just like berries and pomegranates; in other words, the Rama 320:1 holds that a fruit's usage is based location. Mishna Brurah 320:5 explains that [[squeezing]] berries and pomegranates is forbidden rabbinically because some people squeeze them for the juice like grapes and olives. However, all other fruit in the days of Shulchan Aruch weren't squeezed for juice and were eaten. That's why it is permissible to squeeze such fruits because the fruit if considered like a solid and extracting one solid from another is permissible.
* Therefore, the Shemirat [[Shabbat]] KeHilchata (chap 5 note 4) writes that nowadays that it is common to squeeze all fruits for their juice it is forbidden to squeeze any fruit on [[Shabbat]]. On the other hand, 39 Melachos (Rabbi Ribiat, vol 2, pg 328) lists certain fruits which are rabbinically prohibited to squeeze including oranges, lemons, grapefruits, apples, pineapples, cherries, strawberries, peaches, plums, pomegranates, and tomatoes. Similarly, Yalkut Yosef ([[Shabbat]], vol 3, 343 and 491) delineates certain fruits which are squeezed for the juices in some places such as grapes, olives, berries, pomegranates, apples, grapefruits, pears, mangoes, tangerines, and pineapples would be forbidden to squeeze on [[Shabbat]], however, fruits which are not squeezed anywhere such as quince or watermelon one be squeezed on [[Shabbat]]. Yalkut Yosef (pg 344) adds that even when it is permissible to squeeze a fruit, it may only be done by hand and not with a juicer (tool).</ref> One may not squeeze a fruit into an empty vessel with intent to put solid food in afterwards. <Ref> Shemirat [[Shabbat]] KeHilchata 5:5.

# It is permitted to squeeze grapes onto food, but it is forbidden to squeeze grapes into an empty dish even if it is for flavor. <ref> Shulchan Aruch 320:4 </ref>
# However, if one is stringent and does not even squeeze fruits onto food shall be blessed. <ref> Mishnah

# It’s preferable not to squeeze grapes even onto solid foods that will absorb the liquid or be improved. <Ref> Shemirat [[Shabbat]] KeHilchata 5:4 </ref>
# One shouldn’t suck on grapes while holding them in one’s hand, rather one should put the entire grape in one’s mouth, eat (or suck on it) and take out what’s left. <Ref>Shemirat [[Shabbat]] KeHilchata 5:10 </ref>
