Ojā (feminine) [Vedic ojas neuter, also BHS oja neuter Divy 105; from °aug to increase, as in Latin auges, augustus and auxilium, Gothic aukan (augment), Anglo-Saxon eacian; cf. also Greek ἆέξϖ, Sanskrit ukṣati and vakṣana increase] strength, but only in meaning of strength-giving, nutritive essence (applied to food) M I 245; S II 87; V 162 (dhamm'); A III 396; Ja I 68; Dhs 646, 740, 875; Miln 156; Dhp-a II 154 (paṭhav°). See also definition at Vism 450 (referring to kabaliṅkāro āhāra. The compound form is oja, e.g. ojadāna Ja V 243; ojaṭṭhamaka (rūpa) Vism 341.
ojā (= Pali id. ; derived by Childers and Senart from Skt. ūrj, by PTSD from ojas, which seems more plausible), food : Mv i.210.19 = ii.14.20 (prose) (lābhinī bhavati divyānāṃ gandhānāṃ … mālyānāṃ … vilepanānāṃ) divyānāṃ ojānām; ii.131.3 (and 6) (prose) (vayaṃ te romakūpa- [ mss. °pe] vivarāntareṣu) divyām ojām adhyohariṣyāmaḥ; see s.v. adhyoharati (used in Pali , like its noun ajjhohāra, of food). It seems clear that in BHS , at least, ojā means simply food , not essence or the like.
