Count number of occourences of specific values in a string - excel

Question

I have multiple rows with some words separeted by semicolons(;), and need to count how many times a certain word appears in Column A cell strings of Sheet1.
Using two rows for example:
Column "A"
Banana; Apple; Orange
Banana; Banana; Apple
I came up with this code for the counting of the specific word I want to count:
Sub count()
'The count will be registered in "B6"
strcount = "Banana"
For i = 2 to 30
If InStr(Sheets("Sheet1").Cells(i, "A").Text, strcount) <> 0 Then
Cells(6, "B").Value = Cells(6, "B").Value + 1
End If
Next i
End Sub
The problem with this code is that it doesn't recognize the 2 appearences of "Banana" in the second row returning me a count of 2 instead of 3:
Results for each fruit:
Banana: 2
Apple: 2
Orange: 1
I see that the problem is InStr only recognizes if the string is there, but how can I overcome this?
Solution:
Both basodre's and Алексей's answers worked.
For basodre's code I had to change only the delimiter from ";" to "; " (with a space after the semicolon) to match my string.
aFoods = Split(rIterator.Value, "; ")
Алексей's answer works perfectly too, but by the time of this edit is limited for Excel 2019 or above, given it uses the "TEXTJOIN" function and I couldn't come up with a replacement for that.

Answer 1

Here's an example that I think does what you need. Please review, modify to your range, and let us know if it works.
Sub CountWords()
Dim rng As Range
Dim aFoods As Variant
Dim rIterator As Range
Dim counter As Long
Const theFood As String = "Banana"
Set rng = Range("A1:A3")
counter = 0
For Each rIterator In rng
aFoods = Split(rIterator.Value, ";")
For i = LBound(aFoods) To UBound(aFoods)
If aFoods(i) = theFood Then
counter = counter + 1
End If
Next i
Next rIterator
Debug.Print counter
End Sub

Answer 2

Solution with RegExp:
Option Explicit
Sub test1()
Dim re As Object, result As Object, text As String, fruit As Variant
Set re = CreateObject("vbscript.regexp")
re.Global = True
text = WorksheetFunction.TextJoin(";", True, Columns("A"))
'In Excel < 2019 you can use: text = Join(WorksheetFunction.Transpose(Intersect(Columns("A"), ActiveSheet.UsedRange)), ";")
For Each fruit In Array("Banana", "Apple", "Orange")
re.Pattern = "\b" & fruit & "\b"
Set result = re.Execute(text)
Debug.Print "Amount of [" & fruit & "] = " & result.Count
Next
End Sub
Output:
Amount of [Banana] = 3
Amount of [Apple] = 2
Amount of [Orange] = 1

Answer 3

Using regular expression
Sub FindEntries()
Dim mc, rw
Const word$ = "Banana"
With CreateObject("VBScript.RegExp")
.IgnoreCase = True: .Global = True: .Pattern = "(^|;\s+)" & word & "(?=;|$)"
For rw = 2 To Cells(Rows.Count, "A").End(xlUp).Row
Set mc = .Execute(Cells(rw, "A")): [B6] = [B6] + mc.Count
Next
End With
End Sub
